Hello @spike411,
We were responding here on the forum multiple times about this thing and what’s happening. You can use Search. Let me do it for you Omnia 3.10 disappeared Wi-Fi, where you can find details which you are looking for. Also, this thread is a long and old one. It results in mixed version of Turris OS, different drivers, and so on.
However, on the other side, I see, it’s easy to complain about it on community place instead of reaching our technical support department, which is the way which you should do first.
From your post, I cannot see if your 5 GHz Wi-Fi card is detected in lspci or what is exactly going on. The output from the system log, commands would be appreciated, and in that case, you should take a look at Getting help. We are trying to help users as much as we can, even if they are out of warranty!
It would also be helpful to know which version of Turris OS do you have and if you are using vanilla or CT ath10k drivers, which you can choose in reForis.
