Here we go again, after over a month of connecting to 5G network getting amazing speeds, I thought the issues I was experiencing were over. We are again back to loss of 5G network, which occurred right after the firmware update, 1.2003.03.0178.  Now I get issues during my Zoom meetings, unstable connection. I'm so tired of this BS. I am sick of T-Mobile, and the loss of customer service since the merger with Sprint. Spectrum can't be worse than this.

Same issue for me after this same exact update.  I was able to manipulate it by disabling Wifi, rebooting, then re-enabling.  This worked for about 3 or 4 days.  Now it doesn't work anymore.  My speeds are perfectly fine on LTE, but as you said earlier, it SUCKS knowing that you can pull 4x the speed, but can't lock on consistently.  Hopefully it's just a simple firmware upgrade.  I know this upgrade fixed VPN issues and Party Chat issues on Xbox, but it'd be nice if they could combine the two and allow 5G.  When I call T-mobile, they continue to tell me someone is doing physical maintenance on the tower.  Uhh… since March some dude has been hanging from the tower?  Someone should probably go check on him.
