Hey all, I just installed a new ALFA AWUS036ACM with MT7612u driver on my pi router. When it works, it works great!. 300 or so mbps down (270 from steam!), but it seems to crash every few hours. Reloading the driver mod requires a reboot. I'm getting error -110 'mcu_wait_resp'. Are any of you aware of alternative drivers that work better or a self healing solution without reboot?
What OpenWrt-version?
21.02.3. Fresh install
Maybe try snapshot and see, if it works better? Another option could be turning the USB-ports off for a second and then back on with a script, when the driver crashes with uhubctl?
I have a different wifi usb adapter based in the same chipset, if the following file exists:
ls /sys/module/mt76_usb/parameters/disable_usb_sg
try setting true the above parameter with:
mv /etc/modules.d/mt76-usb /etc
echo "mt76_usb disable_usb_sg=1" > /etc/modules.d/mt76-usb
and reboot the rpi

It was set to 0, so I set it to 1. After that my speeds are limited to 100mbps instead of 270mbps like I was getting before. Did you encounter something similar?
As the usb adapter was unusable before setting the parameter, I don't know if are any slowdown, currently the adapter is in a nano pi r4s working in 5Ghz band channel 36 VHT80 and testing with iperf3:

Would you mind sharing which wifi adapter you're currently using and what your wifi config is? Also what software/drivers you're using for the adapter?
Nvm, I'm just stupid. I had setup the integrated radio instead. Big Thanks for the help!
