Installation as per Wiki (also added OEM and OpenWrt stable/snapshot bootlogs there) worked smoothly for me. However, when running either latest stable or snapshot I am consistently/reproducible seeing the following:
I have 3 separate SSIDs one for each frequency, 2.4 GHz, 5 GHz and 6 GHz. If I connect to one after the other it consistently crashes/reboots at the 3rd connection attempt regardless in which order I do those connections.

My Netgear WAX220, albeit only with 2.4 GHz and 5 GHz radios but running similar Mediatek/Filogic chipset, runs stable with more than 2 months of uptime. And my Verizon CR1000A, albeit with Qualcomm chipset, with the exact same Wi-Fi configuration also runs stable in the exact same use case.
Has anybody else experienced such instability issues?
Anyway, as the Acer Predator Connect W6 can be had for as little as 99 bucks here in Switzerland I will just get another one to rule out any kind of hardware issue. Thanks!
