I have two Dell laptops, one is on Windows 11 and the other is a bit older and can only go to Windows 10. I bought a new Tmobile 5G gateway. The newer Dell sees both Wifi names (2.4GHaz and 5GHtz). No problem. The other Dell running Windows 10 doesn’t see either Wife Channel. I have tried everything: new Bios, manual entry of the names and specs, I’m at the end of possible resources to fix this. Dell blames the Gateway. T-Mobile blames Dell.

View originalMaybe your old Dell doesn’t like the combined bands with 1 SSID. There are reports of IOT devices having problems. Try creating a new 2.4ghz SSID and see if your Win10 Dell picks it up.
One thing I noticed with my Arcyadia gateway is that it goes into DFS bands sometimes and my Roku would not see it. I was scratching my head for the longest time until I used Wifi Scanner app (android) to find that out. Then I forgot about it later and scratched my head again. Only to rediscover the DFS channel issue. LOL
Hmm, I’ve noticed a similar quirk --- using an Arcadyan gateway. When using the WIFI ANALYZER app on my Moto phone, the gateway SSID will occasionally not appear. This has not caused a problem for ME (yet) because I connect the gateway to a separate router and use the latter SSID for wifi connections. I sympathize with you but cannot offer a solid solution. Well, I’ll let you know that similar situations exist for others.
The t-mobile router doesn't work with some Dell computers. T-mobile Philippines super was clueless. I solved the problem by connecting via a wifi extender.
