can you get the xb8 in your area? it is a decent upgrade from the xb7 as it has wifi 6e. it also has a 2.5g lan port you can use on your wired PC that will give you the full 2100 speed your internet has to offer. if your pc has 2.5g lan

Honestly, Roger’s Xfinity gateway is a much more powerful router. It is Triband WiFi 6E and has 4x4 for all 3 bands. I am able to get pretty impressive speed with speedtest. I would not recommend using your old Deco x30.

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.

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.

If you have unlimited data depending on your region you have to use xfinity's equipment otherwise pay a $35 a month charge to use your own equipment and have unlimited data. If you have an xb8 those work perfectly fine. If you want faster Wi-Fi you can put the xb8 in bridge mode and still get the unlimited data and then just connect your room wireless router.

Modem goes in bridge mode. Don't expect a huge difference in range or performance, XB8 actually has a decent Wifi 6E chipset. If you want a proper upgrade get a Ubiquiti system with 2 access points, it will outperform the Asus BE98 for the same cost. https://store.ui.com/us/en/category/all-cloud-gateways/collections/cloud-gateway-fiber/products/ucg-fiber https://store.ui.com/us/en/category/all-wifi/products/u7-pro x2

I have Xfinity. I put their Xfi Modem/Router in Passthru mode. I use a Ubiquiti Dream Machine Pro for my router. All my devices use PiHole for DNS. So, it isn’t a problem. I was using my own Modem for years. But, after I upgraded to 2 GB service, they would not support the speed on my Modem, even though it was capable. So, I had to use their modem/router. I only agreed to update my service if I could use it in Passthru mode.
