Frequent Disconnection on 5G Home Internet

Hey everyone.  I think I have found the solution for you.  So, like y'all, I've been having issues with the internet for almost 3 weeks now (my gateway is the arcadyan kvd 21).  When I called T-mobile they just sent a replacement gateway and said that should fix it.  Surprisingly enough, that did not fix the issue, the replacement gateway that was sent did not match their records and due to maintenance on the nearby tower, the gateway wouldn't communicate.  Today, at least for the past 2 hours, there have been no issues with the wifi.  So when it comes to solutions.  It could be because of the manufacturer.  but the advice my spouse and I got was to go in the home internet app, go to  the Networks tab and add a network.  Make ones frequency set at 2.4 and set the others frequency exclusively at 5.  Its been a bit over 2 hours and the wifi hasn't dropped.  We do have the gateway connected to a router that is handling the load pretty well.  Good luck fellow travelers
