If you want to have internet in your home, you need to have a modem. You can either rent one from your internet service provider or buy your own. If you decide to buy your own modem, make sure it is compatible with your ISP and the type of internet connection you have.
If you have an Ethernet port, you do not need a modem. An Ethernet port is used to connect to a broadband router, which then provides an Internet connection.
Most modems these days come with some form of WiFi built in. This allows you to connect your devices wirelessly to the internet without the need for any extra equipment. WiFi is a great way to extend your internet connection to all corners of your home or office, and it’s much easier to set up than a wired network.
A router is a device that connects two or more computer networks. A modem is a device that modulates an analog signal to convert it to digital so that it can be used on a digital network. A router does not need a modem.

I was looking for a cheap replacement after my dependable Motorola Arris SB6141 quietly died the other day after numerous years of service and chose the MB7220. One of the Comcast-supported modems is this one (the SB6141 is no longer supported).Whatever you may think of Comcast, I've had service problems with them for more than ten years and never once. The updates they made to their web tools that now allow users to register their own devices without having to endure the hassle of customer care calls impressed me even more. I installed, registered, and activated the new modem via the internet interface in under five minutes.The MB7220 tested out at 70Mbps down and 6Mbps up. That's not terrible at all considering that I believe I'm paying for a 50Mbps subscription.The bottom conclusion is that this one appears like a solid choice if you need to replace your Comcast cable modem. Because it has fewer channels than more expensive models, it won't be able to pull more than 300 Mbps, which is really not going to happen unless you pay for that kind of service. This one is a bargain at just over $50.

I placed an order for this as soon as it was available since I couldn't stand the Arris models' blaring lights. Thankfully, this item did not let me down. Although the lights are not as bright as the Arris type I had, they are still pretty bright. Actually, I went ahead and covered the lights with some LightDims Original Strength stickers to make them much darker.I just activated it on Comcast's website, waited for it to be provisioned, and everything worked with regard to the setup.I tested my speed before and after installing this modem, and I noticed no difference (55 Mbps down 5 Mbps up and 37ms ping). However, unless I'm mistaken, websites appear to load more quickly now than they did previously. I also visited 192.168.100.1 where I changed my login and password and reviewed all the device information (even though I had no clue what most of it meant).Overall, especially compared to the latest Arris devices, I highly suggest this cable modem.UPDATE (5/2016): I've had this modem for more than three months, and it's still in fine working order.UPDATE (7/2017): It has started crashing on me after 1 year and 6 months. A Twitch stream will crash if I watch it for more than six hours. It won't work until I repeatedly unplug it and then plug it back in.9/30/2017 UPDATE: A few weeks after my previous evaluation, it abruptly quit resetting itself. I have no idea why it did that initially, but it hasn't stopped working since. Since I have no idea what transpired, I revised the rating back to 4 stars. I did, however, email Motorola, but they never replied. Customer service seems to be terrible. The reason for the 4 star rating is the poor customer support paired with the sporadic resets that occurred for almost a month.(01/07/2018) UPDATE: I continue to experience connectivity issues when attempting to watch a Twitch stream. However, it only occurs when I watch Twitch. I'm not sure if Comcast is throttling Twitch, if there is a problem with Twitch, or if the problem is with my cable modem. I tried directly connecting the cable modem to the PC, but the issue persisted. I'm glad to know that the problem is not with my ASUS router. Certainly, the top of this cable modem becomes quite warm. Let me know if anyone has any suggestions.(06/03/2018) UPDATE: I haven't had any more modem problems since the recent upgrade. Only if there are any problems will I provide a new update.

My internet connection, xfinity performance pro, has a 150 mbps down and 5 mbps up rating. I've been using the Arris SB6141 modem, which has 8 down-channels and 4 up-channels. It's a terrific modem, with no problems, but its maximum speed is 120 down-channels and 5 up-channels. I bought the Motorola SB7621, which has 24 channel down and 8 channel up, figuring why not receive the speed I'm paying for. With a latency of 19ms, internet speed is currently 180mb/s down and 6mb/s up. I'm glad I'm finally getting the speed I paid for. Yes, the upload speed didn't change much, but xfinity doesn't offer 8 channel up in my location, so that's why. This indicates that even though this modem supports 8 channel up, it only displays 4 active up channels when you log in. xfinity is to blame for this, not the modem. The download channels function well; all 24 channels are visible and operational. Yes, I could have bought a 16 x 4 modem to have the same speeds as now, however at the time of purchase, this modem cost less or the same as all the 16 x 4 modems. By purchasing this Motorola, I will be covered even if I later increase my internet speed. The fact that this modem uses the Broadcom chipset rather than the Intel puma is an additional plus.The modem is well-packaged and comes with clear instructions. It was easy to set up. I was not required to dial xfinity. After connecting only the modem to my PC, all I did was go to Motorola.com and that brought me the xfinity activation page. Then simply enter your xfinity login information and follow the on-screen instructions. Very simple, which I appreciated since I didn't want to spend time on the phone with Xfinity support.I hardly seldom write reviews, but I felt this tiny box merited one, and I hope this will be helpful to someone.

For service rates of at least 300 Mb/sec, the Netgear CM600 cable modem is a supremely dependable DOCSIS 3.0 cable modem. It lacks the problematic Intel Puma 6 chipset seen in many higher-end cable demos, making it a more dependable option than the company's CM700 variant.There might be a drawback for certain people, but it has nothing to do with the CM600. It should be remembered that ONLY the ISP can give ALL firmware updates when using the CM600 interface (in my case, Spectrum). Spectrum would benefit if the firmware were updated, however it is unclear if they will do so (when and if necessary).Furthermore, it has been clarified that Spectrum is unable to remotely troubleshoot problems with "non-standard" cable modems and routers. These are any devices that are not the normal complimentary cable modems and routers that Spectrum installs as part of their service. However, they can perform a reboot to make sure the CM600 is operating properly.Funny how I see this as more of a benefit! I enjoy that Spectrum is unable to change the settings on my modem or router because I am a certified network support specialist and am more than capable of doing so on my own.It's as simple to set up the Netgear CM600 cable modem as plugging it in and turning it on. Within seconds of connecting the Internet wire to the back, the CM600 was ready for use.The CM600 is a one-trick pony; it only functions as a cable modem. Internet data is transformed from cable data. Given the requirements and the high-quality parts, it performs its unique task exceptionally effectively. The CM600 is designed to extract a signal from a dubious or unreliable line. When other, less reliable modems fail, it will still be able to connect you to the Internet. I haven't experienced any sporadic cable dropouts since getting this modem. Keep in mind that it lacks an integrated wifi or wired network. A router of this kind must be purchased separately.A quick aside: Your home's WiFi universe's Grand Central Station is the router. Sending and receiving many data streams efficiently and effectively between a home full of WiFi-enabled devices, such as smartphones, smart HDTVs, PCs, tablets, cameras, and other devices, requires a significant amount of computing power. A radio transceiver is a router. The more information it can transmit across greater distances, the more powerful it is. More sensitive devices can detect data being transferred 500 feet or more away. I suggest the Netgear Nighthawk® R7000P to get the most out of your Netgear CM600. It is a fantastic dual-processor performer at an unbelievable price and was created to manage the requirements of the tech-enabled home.No. I'm not employed by Netgear.

For Xfinity Gigabit Internet service, I bought the Arris SB8200 because they were offering a two-year deal for the same price as the 400Mbps plan ($69.99). So I made the decision to buy my own modem to replace my outdated Motorola (Arris) SB6141 in order to save about $15 a month. For an 8x4 channel Docsis 3.0 cable modem, my SB6141 provided me with 259Mbps down and 35Mbps up on my previous plan of 400Mbps down and 35Mbps up. Therefore, having had an excellent product with the 6141, I opted to order another one since Arris purchased Motorola's modem cable section. The Arris SB8200 is the only Docsis 3.1 modem featuring two 2Gbps down Ethernet connections, making it the most future-proof modem available at the time this article was written. Even better, a refurbished model is available for half the cost!A Broadcom BCM3390 chipset, which is a much-needed upgrade over the SB6190's Intel Puma 6 chipset, is found within the Arris SB8200, along with 3GB of RAM, 128MB of Spansion S34ML01G200TFV00 NAND flash memory, and 16MB of Macronix MX25L12805D SPI NAND flash memory. The SB8200 has upstream bonding channels of up to 8 SCQAM and downstream bonding channels of up to 32 SCQAM or two OFDM (32x8 SCQAM and 2x2 OFDM). There are only Gigabit Ethernet connections, therefore the maximum speed you can expect is 950 Mbps on average, contrary to the box's 10 Gbps marketing claim. Even if your neighborhood doesn't provide Docsis 3.1 or Gigabit internet plans, this modem will last you for many years. Additionally, this modem has 3GB of RAM, compared to the 256MB or less of the other Docsis 3.1 modems! RAM! Oh, and with most carriers (including Xfinity), you may call them and pay a small price (Xfinity charges about $5.95 if I recall correctly) to add a different IP address for the second Ethernet connection. This would be excellent if you wanted to link your home network to the second and your game console to the first for the fastest speeds possible. And eventually, when the two Ethernet ports are combined, you'll be able to activate 2Gbps!The equipment was quick and simple to set up; all you need to do is plug in the coaxial wire, Ethernet cable to your device (which, for 99% of people, will be a router), and power cord to get started. I'm up and running in ten minutes after making a brief call to my internet service provider (Xfinity in my case) to add the HFC MAC address. If you know what you're doing, you can convince Xfinity to override their attempt to dispatch a technician. As we'll discuss later, gigabit internet may be rather fickle, which is why Xfinity insists on sending a technician out for every installation of a gigabit service. Again, since this is only a modem, a router is required if you want wifi or the ability to connect multiple devices.The Arris SB8200 performs incredibly well, and I had no trouble getting my allocated modem speeds from my Xfinity account. Fast.com also counts backend speed as actual can only be 950Mbps as I previously indicated, yet I was able to test 1.4Gbps down and 45Mbps up. The results of my testing on Speedtest.net are virtually always 930–960 Mbps down and 40–50 Mbps up. Just my upload speed is faster than most people's download rates, and these speeds are AMAZING! The modem lights will have a blue light for downstream and a green light for upstream as of right now, Xfinity is only using Docsis 3.1 for the downstream channels (this is not an error or bug).My Xfinity subscription was giving me problems, including resets, sluggish speeds (300 Mbps max down), etc. Xfinity dispatched a technician, but nothing happened. So another rech arrived and discovered a massive amount of ingress coming from 4 lines on my tap. He released the traps, and I was able to resume using Gigabit speeds. The resets then began, happening at night approximately every ten minutes! Every night, only between the hours of 10 p.m. and 7 a.m., was it happening! I had additional technicians and supervisors out. After a month (and a lot of my time and speaking up), the problem was found to be a defective line amplifier that was generating noise and caused my upstream to spike into the high 50s, which leads to modem resets and t3/t4 faults. Now, although my neighbors were experiencing problems with some channels and sluggish internet, their modems WERE NOT RESETTING! And we knew my modem wasn't malfunctioning because it worked flawlessly for more than 12 hours each day and had no issues at all till night fell every day. Furthermore, while I frequently had internet outages, my neighbors never did. As a result, the Arris SB8200 is very sensitive to t3/t4 errors, and the Xfinity-owned gateways and modems have significantly higher thresholds for errors and resets. Additionally, Arris released a firmware update earlier regarding a strong sensitivity to t3/t4 failures, and even though I had the most recent version, I was still experiencing problems. They still need to improve on this. If you are having problems with your Arris modem, go to http://192.168.100.1 to view basic signal data, modem error logs, and modem and firmware information. To seek assistance and identify any issues, you can utilize this information and post it in the support forums.However, now that the line and backend errors have been fixed, everything is running smoothly and I'm saving a ton of money (the new Xfinity modem charge is $14 plus tax and it will be $15 by the beginning of 2020 so you pay for the modem in a little over a year) every year. Additionally, you'll have the most recent technology that is even better than the Xfinity modems and gateways, many of which use the Puma 6 chipset that I previously mentioned (causing severe lag and timeouts which can kill online gaming or video watching). I'm paying $69.99 for gigabit speeds that are 950 Mbps down and 48 Mbps up, which is an unbeatable value that you won't find anywhere else! It's fantastic for competition that the Arris brand is preserving the Motorola spirit! The Arris SB8200 is the best modem you can currently get for your money, and if you can locate one on Amazon that has been previously owned, all the better (they didn't have any when I got mine, but three weeks later they did and they were $100 less expensive), they did!

The Arris SB8200 is the only Docsis 3.1 modem featuring two 2Gbps down Ethernet connections, making it the most future-proof modem available at the time this article was written. Even better, a refurbished model is available for half the cost!A Broadcom BCM3390 chipset, which is a much-needed upgrade over the SB6190's Intel Puma 6 chipset, is found within the Arris SB8200, along with 3GB of RAM, 128MB of Spansion S34ML01G200TFV00 NAND flash memory, and 16MB of Macronix MX25L12805D SPI NAND flash memory. The SB8200 has upstream bonding channels of up to 8 SCQAM and downstream bonding channels of up to 32 SCQAM or two OFDM (32x8 SCQAM and 2x2 OFDM). There are only Gigabit Ethernet connections, therefore the maximum speed you can expect is 950 Mbps on average, contrary to the box's 10 Gbps marketing claim. Even if your neighborhood doesn't provide Docsis 3.1 or Gigabit internet plans, this modem will last you for many years. Additionally, this modem has 3GB of RAM, compared to the 256MB or less of the other Docsis 3.1 modems! RAM! Oh, and with most carriers (including Xfinity), you may call them and pay a small price (Xfinity charges about $5.95 if I recall correctly) to add a different IP address for the second Ethernet connection. This would be excellent if you wanted to link your home network to the second and your game console to the first for the fastest speeds possible. And eventually, when the two Ethernet ports are combined, you'll be able to activate 2Gbps!The equipment was quick and simple to set up; all you need to do is plug in the coaxial wire, Ethernet cable to your device (which, for 99% of people, will be a router), and power cord to get started. I'm up and running in ten minutes after making a brief call to my internet service provider (Xfinity in my case) to add the HFC MAC address. If you know what you're doing, you can convince Xfinity to override their attempt to dispatch a technician. As we'll discuss later, gigabit internet may be rather fickle, which is why Xfinity insists on sending a technician out for every installation of a gigabit service. Again, since this is only a modem, a router is required if you want wifi or the ability to connect multiple devices.The Arris SB8200 performs incredibly well, and I had no trouble getting my allocated modem speeds from my Xfinity account. Fast.com also counts backend speed as actual can only be 950Mbps as I previously indicated, yet I was able to test 1.4Gbps down and 45Mbps up. The results of my testing on Speedtest.net are virtually always 930–960 Mbps down and 40–50 Mbps up. Just my upload speed is faster than most people's download rates, and these speeds are AMAZING! The modem lights will have a blue light for downstream and a green light for upstream as of right now, Xfinity is only using Docsis 3.1 for the downstream channels (this is not an error or bug).My Xfinity subscription was giving me problems, including resets, sluggish speeds (300 Mbps max down), etc. Xfinity dispatched a technician, but nothing happened. So another rech arrived and discovered a massive amount of ingress coming from 4 lines on my tap. He released the traps, and I was able to resume using Gigabit speeds. The resets then began, happening at night approximately every ten minutes! Every night, only between the hours of 10 p.m. and 7 a.m., was it happening! I had additional technicians and supervisors out. After a month (and a lot of my time and speaking up), the problem was found to be a defective line amplifier that was generating noise and caused my upstream to spike into the high 50s, which leads to modem resets and t3/t4 faults. Now, although my neighbors were experiencing problems with some channels and sluggish internet, their modems WERE NOT RESETTING! And we knew my modem wasn't malfunctioning because it worked flawlessly for more than 12 hours each day and had no issues at all till night fell every day. Furthermore, while I frequently had internet outages, my neighbors never did. As a result, the Arris SB8200 is very sensitive to t3/t4 errors, and the Xfinity-owned gateways and modems have significantly higher thresholds for errors and resets. Additionally, Arris released a firmware update earlier regarding a strong sensitivity to t3/t4 failures, and even though I had the most recent version, I was still experiencing problems. They still need to improve on this. If you are having problems with your Arris modem, go to http://192.168.100.1 to view basic signal data, modem error logs, and modem and firmware information. To seek assistance and identify any issues, you can utilize this information and post it in the support forums.I'm paying $69.99 for gigabit speeds that are 950 Mbps down and 48 Mbps up, which is an unbeatable value that you won't find anywhere else! It's fantastic for competition that the Arris brand is preserving the Motorola spirit!

The Quick Start manual included in the box made setting up the Xfiniity compliant modem incredibly simple. A word of caution for Comcast / Xfinity customers: choosing the option to text an activation code is a joke when going through the setup Wizard. The code is only good for 15 minutes but I didn't get the text until 30 minutes had passed. Instead, just use your Xfinity account name for the activation and provisioning.While my own six-year-old, reliable Motorola Surfboard SB6580 was still operating as intended under DOCSIS 3.1, Xfinity found numerous reasons to nag me about an upgrade and how much I was missing out on by not having a 3.1 modem. Since I like to own my own modem, I limited my options to the ARRIS Surfboard SB8200, Netgear CM1000, and this Motorola MB8600 after looking over the acceptable modems for my area on Xfinity's approved equipment page. At 1001 Mbps, 32 down x 8 up DOCSIS channels, and DOCSIS 3.1, all three are equivalent.The Arris is extremely popular among the cool kids, and for good reason—especially since they chose Broadcom's chipset over the extremely problematic Intel PUMA chipset. It's a sweet treat with 3GB of RAM and 128MB /16GB of NAND flash memory. And I would have happily bought it if it weren't a hideous white box that clashes with everything in my place.I am aware that vanity's name is Monkey Rat.I've never been a big fan of Netgear, and I thought that its hardware—128 MB of flash memory and 256 MB of RAM—was insufficient. With potential residential speeds now around 1Gb, this is ultimately not a major game-changer, although one would anticipate more from a company with the name Netgear. Although it has many features, which is impressive for a cable modem, I just didn't see a reason to go down this road.Now, that contrasting white Arris was beginning to appear more appetizing.Then I made a pleasant comparison between the MB8600 and both. 512 MB of RAM and 128 MB of NAN — a dollar less expensive than the Netgear with a doubling of the RAM, and although marginally more expensive — and unquestionably lacking in hardware — than the Arris. However, I paid extra for the potential to bond as many as 4 different lines in the future. Although faster than a gigabit bandwidth isn't necessarily on the horizon and LACP technology necessitates a higher end router, this device is well positioned for a future with a potential for 4Gb.A word of warning: the device is HUGE. If you are familiar with prior surfboards, you will see that this one is far taller and lacks any mounting options. But because of a well-ventilated grid design on the side, it provides excellent ventilation.So how does it function? My internet package is awesome! Wired speeds on speedtest.net show a boost, but it's not really all that visible. Whether connected directly to the cable modem or my ASUS RT-AC86U router, notebook and desktop performance was insignificant (stop laughing; I can guarantee you, I've never seen that even in the middle of night). Although I thought this was a little strange as my Google Pixel 2 phone and nVidia SHIELD K1 tablet are still traveling through a router, I can't dispute with the results.I need to check out the built-in spectrum analyzer utility on the MB8600, which I keep forgetting to do. When I do, I'll add an update.In the end, I like it; I play the old Everquest and noticed faster response times, but, like I said, Microsoft isn't doing anything earth-shattering or sky-igniting. I don't really have any qualms about streaming the occasional movie, and I can only commend the device for its dazzling Wi-Fi increase, which I am at a loss to explain.Next, I might upgrade my router and replace my Cat5e with Cat6 in an effort to squeeze out a few more Mbps. But in all seriousness, I believe it is time to call Xfinity and perform some line tests. I'll also provide you updates on that.

I bought this to replace a modem and router from Netgear that were getting clumsy. I ran a speed test after installing and activating using Spectrum. For 100gbps, I pay: I was able to connect directly using an Ethernet wire at a speed of 119 mbps. I then have 98 mbps through the 5.0 ghz speed. But when testing at 2.4 GHz, my speed was 33 mbps even when my laptop was right near to the cable modem. That is essentially the expected speed for any 2.4 ghz connection, based on what I know about it. When buying, keep in mind that the 2.4 GHz frequency has a greater ability to penetrate residential barriers. I would strongly recommend it for the price if you plan to use it via a direct connect or neighboring wifi on the 5.0 GHz frequency. If you require higher speeds over a greater distance, you could prefer one with a stronger antenna signal.
Assuming you would like a 50-word answer to the question: How do you set up a modem? To set up a modem, you will need an Ethernet cable, a computer, and a modem. First, connect the Ethernet cable to the modem and the computer. Next, power on the modem. Finally, open your browser and follow the instructions on the screen to complete the set up.
A good modem will generally cost you around $60. This is the price for a decent quality modem that will provide you with a good connection speed. If you want a top of the line modem, you can expect to pay closer to $100.
A modem is a device that connects a computer to the Internet. A router is a device that connects two or more computers to each other.
The three most common types of modems are dial-up, digital subscriber line (DSL), and cable. Dial-up modems are the oldest and slowest type of modem. They connect to the internet over a standard phone line. DSL modems connect to the internet over a digital phone line. They are faster than dial-up modems, but slower than cable modems. Cable modems connect to the internet over a cable TV line. They are the fastest type of modem.
A modem is a device that converts digital signals to analog signals so that they can be sent over telephone lines, and vice versa. There are four main types of modems: dial-up, DSL, cable, and satellite. Dial-up modems are the oldest and most basic type. They use a telephone line to connect to the internet and are very slow, with speeds of around 56 Kbps. DSL (Digital Subscriber Line) modems use a phone line as well, but they require a special DSL filter. They are much faster
