Has your Surface Pro for Business with Snapdragon Elite had an Internet stability issue on 6 GHz WiFi bands?

My Surface Pro for Business with Snapdragon Elite started losing Internet connectivity about four weeks ago. I would find the machine still connected to WiFi, but without an Internet connection. I was getting lots of BITS errors and DNS errors. I had to reboot. It's one thing to start the day with having to reboot, but when it drops while working, it's a real productivity drag, especially if you get versioning problems with your 365 documents. Then the number of items to be indexed on 365 grew every day. I was having OneDrive sync issues. I followed all of the advice that Copilot could give me. (It was rather helpful, but sometimes ignored what I had already reported to it.) I even reset OneDrive, a painfully long ordeal given my the not-so-broadband broadband provided by my ISP. I finally reached out to Microsoft. The first agent had me update all of my drivers despite my PC presumably being up to date. She transferred me to another person to help with 365, who immediately transferred me to someone on the Surface team. That person wanted me to reinstall Windows 11, including wiping my disk drive clean. That was not palatable, and we moved on to just reinstalling Windows with the data save option. The reset was not easy; eventually, I ascertained that I had to suspend at least one of my services. I never figured out which one, so I suspended OneDrive, Norton, Carbonite, and Dropbox (and deinstalled them as well). This got me further into the reset process, which then failed at a later point. I ended up decrypting my SSD. The reset then worked like a charm. OneDrive resynced in less than a day as did Carbonite and Dropbox. I left Norton for later after I had re-encrypted my SSD. Unfortunately, that person neglected to mention that I would not be able to reuse my .ost files; I should have exported them first. It took about three days to resync my new Outlook files for my six or seven accounts. The problem persisted. Then our other identical machine started to lose its connection. It wasn't being used as much and was never left on overnight. Finally, I decided to switch from the 6 GHz band to 5.2 GHz. It hasn't dropped once in three days. The same now goes for the other PC. What's the value of a router supporting a 6 GHz band if our newest devices can't maintain Internet connectivity?
