Xfinity - Advanced Gateway (XB7)

The XB7 modem has WiFi 6 and the XB8 has 6e. You can get the XB7 starting at the Fast speed tier.

If all you have is one Xfinity device then you have an Xfinity Gateway which is a combo router/access point. If it's working fine I wouldn't upgrade it. If you need to upgrade then I'd just get a newer XFi gateway which is all in one. Buying a modem + router is gonna cost $250+, then they won't really help you if you have issues.

They're fine. The XB7 has fewer complaints than the XB8 or XB10 and the techs will tell you that the older ones (XB7) are more reliable. Whether that's true or not, who knows. But XB7 and/or XB8 are good. I stopped using it because I like messing with stuff and wanted an OpnSense box as the router and Ruckus access points, but before that I was using the XFi gateway as-is.

"Gaming Router" is just a Marketing thing used to sell overpriced routers to suckers!!! It's not going to be magically better than any other normal router. The simple fact is there is a MAX output signal that can be used to even be allowed to sell your product. I know my Xfinitiy XB7 Modem/Router had pretty good Wifi though I used my own Wifi Access Points with my Prosumer Gateway(Router). As you move up from 2.4Ghz to 5Ghz and the newest 6Ghz, you get faster speeds, but your range is reduced, especially going through walls. It's why most smart devices are 2.4Ghz only. It's more about a good, reliable connection over speed. I don't know how far away you are from your Modem/Router. How many walls? Sometimes this can be helped with a MESH Setup. Basically it's a setup with a main router and 1 or 2 MESH Units you spread around. For example, you have your Router located at one end of your house and at the other end of your house your Wifi is weak to dead. Well you would take one of the mesh APs Mesh Access Point and place it in the middle. So that it can still have a connection t the main router, and send that signal further to the other side of the house. You wouldn't want it located in the weak or dead room, because it would have the same issue as your device at that point. MESH just means that the AP is Wireless. It only plugs into a power outlet. AP (Wifi Access Point) is just a device that does one thing, WIFI. Being WIRED into the network is better. Wired back to your Router. That AP could then be placed right in the dead room and give you great WIFI like standing next to the router. I use Unifi APs. You can see a bunch of examples of AP's [here!](https://store.ui.com/us/en/category/all-wifi) Other companies also make these things. TP-LINK OMADA line for example. Many others!!! These things are powered by POE. Power Over Ethernet. Either by using an Injector, which is a small device you plug into a power outlet with 2 Ethernet ports. One side is powered that goes to an AP or a POE camera, and the other one go's to your network. Of course there are POE Switches. If you have a bunch of POE devices, it makes far more sense to use a POE switch to power everything, using a single electrical plug for the switch then a bunch of injectors and all their plugs. I have 2 AP's and use 2 Injectors. Some of the MESH systems out there may also allow you to plug into your network to have a wired AP as WIRED is always better and the Injectors on those is built in, so you just have a power plug. A big part coms to being a Renter or a Owner. If you rent, running Ethernet cables can be a problem. you can't do that. If you own, you can pretty much do whatever you want. When I got my house, one of the first things I did was create a large wired Network. That is the time to do it, when you don't have your house filled with crap. If you are a renter, then a MESH setup is about the only option. It's not a magical fix.

The XB7 is WiFi 6, and it has both 2.4GHz and 5GHz bands. The XB8 is WiFi 6E, and has 2.4GHz, 5GHz, and 6GHz bands. xFi Complete is essentially a “plan” add on. It includes a modem rental, unlimited data, Advanced Security, and some other smaller details that are in the fine print on the Comcast website. The Xfi Pro is a brand new “plan” that essentially encompasses everything on Xfi Complete, but includes a Pro WiFi Extender (formerly known as the Storm Ready device). Again, there’s some small print on the Comcast website. Don’t quote me on the differences between the two, as the Pro is genuinely brand new, and I’m still familiarizing myself on the details. But what I listed should be fairly accurate. Hopefully that helps you out a bit.
