Re: Help!! No wireless for Ralink MT7620a + MT7610e eval board

Log show that eeprom setting for wlan is absent:

rt2800_wmac 10180000.wmac: failed to load eeprom property
ieee80211 phy0: rt2x00lib_request_eeprom_file: Info - Loading EEPROM data from soc_wmac.eeprom'.

So you need find it. Usually it exist at offset 0 of /dev/mtd2. To check pls show

hexdump -C /dev/mdt2

If it is there, to extract it:

cd /lib/firmware
dd if=/dev/mtd2 of=soc_wmac.eeprom count=1

And reboot router.
