Xfinity WiFi Not Listed in Windows 10 Laptop. Not able to Change WiFi Mode

Hi All

I am having hard time trying to connect my Dell Windows 10 Laptop to Xfinity WiFi. I have both 2.4 and 5 Ghz WiFi enabled separately (due to many Smart devices at home) and either is getting listd in the availalble WiFi networks. All of the other devices at home are working and even another Windows 10 Laptop also is able to connect to WiFi. Issue is only with one Laptop and that laptop is able to connect to other WiFi Networks and even the xfinitywifi open WiFi also. 

I saw the same issue reported in many threads and the suggestion was to change the WiFi mode from 802.11 g/n/ax to just 802.11 g/n. I am not able to do it in the Admin tool as its greyed out for me. Called Xfinitiy support and they have no clue what I am talking about. They simply restarted my Gateway and told it will fix in an hour. 

Please help

Thanks

So some Dell computers will only connect on certain channels, that being said, you can go into the device manager, click on network adapters, click on your wifi card, under advanced tab, you will probably see  a long list of options, the setting will be different depending on make of wifi adapter, look for something like "mode" or "band preference" something along those lines, it might say auto, in the drop down menu, select "G" or similar, there could be more then one setting, set the same, this solved my issue, also i see this issue on older 2.4 g wifi cards, if your card is 2.4 g, personally, i would invest in a under $15 usb high speed network adapter, that would give you access to the much faster 5G band, but that's just me

Thanks a lot @jlavaseur for the response. I tried to play around with the WiFi settings under the Advanced tab and none of that helped. 

There are options like "Preferred Band", "Wireless Mode", "Channel Width" and many others and nothing really helped. 

Do you have any other suggestions? The funny thing is that was able to connect to the Gateway few months back, but not now. I dont use this laptop always, so dont know what changed on the Gateway for this stop working. Also the Xfinity open wifi and the cable also works. Just the 2.4 and 5 Ghz Wifi connections won't.

It would need to be changed in the gateway's settings itself if it is even possible any longer.

@eg i have successfully just changed the band on my wifi card from "auto" to "G" with out changing the gateway, on a side note, i noticed i occasionally have to change the link speed from auto to the desired speed on certain network cards, i don't equate this with a problem with the Xb7, but just older technology trying to keep up ...

I'm curious as to how changing a network client's settings can possibly physically change the settings in a router. It's two separate systems / devices.

it doesn't change the routers settings at all, the router is already configured to use those bands by default, backward compatibility, its just older network cards don't seem to be able to negotiate the connection on 'auto" You can change the routers band to use just "N" and "G" it works the same way, but you effect the rest of the devices on your network negatively, as they no longer can access the "AX" band,  personally i find it more productive to just address the rogue network card ...

Like I said, some Dells only connect on certain channels, possibly your router changed channels,  that would be my guess, maybe a setting option for that…

Also win 10 has a hotspot option, you could possibly setup a hotspot on your other win 10, the hotspot shares the host computers internet connection, I have used this option for a quick and easy guest network, you can set logon and password, it has various options, maybe a work around

Thank you for the comments

WiFi Adapter settings have not helped so far. I had tried the Hotspot option earlier. Was not able to start WiFi hotspot when I was already connected to WiFi. I think it will work only to share Internet from LAN through WiFi.

For now did a work around using an old router by connecting to the main Xfinity Gateway and keeping in Bridge mode. I am able to connect to the WiFi from the old router on my old Win 10 Laptop. This setup seems to be ok for now, even though I have to keep 2 routers online.

Thanks a lot for all the help extended !!

Excellent! I find there is usually a way… now that you jogged my mind, I might have used a usb WiFi dongel  just for future reference, if you ever need to replace your Xb7, go to the xfinity store to pick it up, have them activate there, you go home hook it up, it reboots your online, plus you have full access to the gateway admin panel, nothing is grayed out…
