Help and Support Raspberry Pi

Hi!

I have a problem with my USB WiFi dongle (ASUS USB-AC51) which is built on the MT7610u drivers.
The network card is visible in ifconfig and under lshw, BUT i’m unable to scan for any networks, nothing shows up!

When going trough dmesg i clearly see a few errors

How can i correct the faults and make my USB wifi card functional?
Looking forward for your help and input :slight_smile:

Okay got it working by doing this:

“mv /lib/firmware/mt7610u_sta.dat /lib/firmware/mt7610u_sta.dat.bak” and rebooting, sadly only 2,4GHz wifi networks are visible.

Is there a newer driver available for 5GHz?

Now the 5GHz networks are visible after i turned down the 5GHz Wifi channel under 100 :slight_smile:
