I hope this helps someone experiencing my scenario where Laptop WIFI Adapter Driver is old...

After installing the T-Mobile Gateway Gray Kit I was unable to see the SSID name in the list of available networks on my 2017 HP Laptop running Windows 10, but everything else in the house connected, since I renamed Gateway to the previous router SSID name. I searched the type of wireless adapter I have in laptop, Intel Dual Band Wireless-AC 7265, and visited Intel site to update Wireless adapter Driver to the latest for my device, 19.51.33.1. After the update I am able to see the Gateway SSID and laptop connects.

To find WIFI adapter name: Right click internet icon in Task Bar > Open Network & Internet Settings > select 'WIFI' > 'Harware Properties'. Look for Manufacturer Name an Model. Go to manufacturer site and search for driver download; mine was an executable file, which installed and updated after a few prompts.

One may access the T-Mobile Gateway Settings by connecting Laptop directly to Gateway via LAN cable into back of Gateway and enter 192.168.12.1 into browser. One may view and modify the 2.4GHz and 5GHz WIFI Networks Settings. Username: admin > Password: (Is what you determined during installation, or the default listed on bottom of Gateway.) I'm using my laptop on the 2.4GHz network, so I changed the Gateway Channel from default 1 to 11, this didn't affect the other devices already connected. None of these changes had any affect on laptop SSID discovery until after I updated the Driver.

Vypur!!! You da man. Been trying to figure this out for 2 days. I have the same wireless adapter as you in my somewhat older Alienware computer. T-mobile wifi would not show up in the network list. Did show up for every other device in the house including Roku's. I tried updating the driver by searching the internet for latest driver. Was informed that I had the latest driver. That is where the problem lies. I actually did not have the latest driver. Why it failed to determine that I don't know. Anyway, I followed your advice and went to Intel site and found the actual latest driver and downloaded and installed. Then I immediately checked the wifi network list and viola!!! There was my elusive T-mobile wifi network ready to connect. All good now, so thank you sir for your help. THIS SHOULD BE YOUR FIX, EVERYONE. Don't trust Windows to search internet and find latest driver. Go to site yourself and find it if you are having issues.
