Hi. Had the same issue, Alexa didn't connect with T-mobile gateway. It worked 3 months as it should and then it stopped to connect to wifi. After some time with the amazon representative over the phone, I went to the settings for T-mobile gateway and change the frequency from "Automatic" to 2.4 Hz. And it was done! No issue so far. Hopefully it can help someone else as well !!!

I purchased two Echo Show 5 devices and, although I was able to connect both on the 5G in the beginning, my home lost power briefly and I could not get them reconnected on 5G or 2.4G.  Hours online and phone with Alexa support and no go. I actually had Amazon exchange the Echo Show devices lol.

After reading this I checked  my settings in My T-mobile gateway app. I have settings for 5G and 2.4G but in the 2.4G I changed the setting on the WPA Version from WPA2/WPA3 to WPA2. I then rebooted my gateway and my Echo Show and viola! They both connected seamlessly.

I have one Roku TV, one Roku streaming device, my phone, 5 Wyze cameras and now 2 Echo Show 5 connected and everything is running beautifully.

Hope this can help someone else as well.
