I meet a problem when I flashing the snapshot to my Lenovo Y1, I can't find the 5G radio in wireless settings. How do I find the problem is?
I had this problem too. ( I think it's a bug? Other router... )
You could flash a stable version and then copy
/etc/config/wireless
Otherwise you could try to add it manually
config wifi-device 'radio1'
option type 'mac80211'
option channel '36'
option hwmode '11a' # or '11n'...
...
I have try this configuration according update without wipe configuration. Doesn't work else.
Here's my friend Joshua Holborn say:
[ 0.409496] mt7620-pci 10140000.pcie: MT7620 PPLL unlock
[ 0.414640] mt7620-pci: probe of 10140000.pcie failed with error -1
Can't find the 5G chimps on PCI-e, may not about the mt76 problem.
Problem resolved.
