I have Ubuntu 22.04.1 LTS on mini pc, never used Linux before, used windows 10 and everything worked fine.
Router model Asus RT-AX92U,
WIFI network that I use set up as
Tri-Band Smart Connect (2.4 GHz, 5 GHz-1 and 5 GHz-2) all channel settings set to Auto.
When I connect to my home WIFI I get very slow speed, if I run hot-spot on my phone I get probably the max speed my phone can provide (~40mbps).
When I check router admin panel it shows that my mini pc connected using 5G-1 band.
This is the only device that has this problem. I tried every possible solution that I was able to find but nothing works.
tried to set connection settings such as channel and band, edit
iwlwifi-7265d-29.ucode to /lib/firmware, updated OS and apt etc.
spent 2 days trying to “fix” it
How fix it?
