Internet won’t work after new router on laptop

[Idkjustfixtheis]

I’ve literally tried everything and can’t seem to find any help form xfinitity for this issue. I got a new router recently and it can’t connect the WiFi to my laptop but can connect to everything else. This happened after I got the new router so I don’t think it’s my laptop. I’ve rest the gateway many times, changed passwords and wifi names and still nothing. I talked to two agents and called xfinity and still nothing. This is ridiculous and I’m seriously considering going back the old router!

[EG]

The two WiFi bands have recently been combined into one with the Comcast gateway devices. Some devices get confused and don't know how to see / talk to combined bands.

If you are not using any Xfi Pods, you can try separating the 2.4 and the 5.0 bands and give them two different broadcast names / SSID's;

Associate the laptop with the 2.4 or the 5.0 (whichever one works) band's SSID (broadcast name) and password.
