#13452 assigned defect

DIR-825 wlan phy1 invalid mac address

Reported by: yatakama <atakama0512@…> Owned by: juhosg
Priority: normal Milestone: Barrier Breaker 14.07
Component: kernel Version: Trunk
Keywords: Cc:


After upgrading to AA 12.09 on a DIR-825 rev B2, the second radio doesn't come up and the kernel log shows:

ath: phy1: eeprom contains invalid mac address

I assume this is related to the changes in r35731.
I reverted to 12.09 RC1 on the same router and the second radio comes back up with the correct mac address, so the caldata partition doesn't seem to have been corrupted.

Just flashed r41353 and the second radio works. I still have these error messages in the log:

kern.err kernel: [   12.250000] ath: phy1: eeprom contains invalid mac address:
kern.err kernel: [   12.250000] ath: phy1: random mac address will be used:

ifconfig then shows the real mac address, not the random one previously generated.
Speaking of mac addresses, I noticed the following pattern: br-lan, eth0 and eth0.1 have the same mac, ending in 4d (in my case), then eth1 is 4e, then wlan0 is 4d again and wlan1 is 4f. I distincly remember that the stock firmware assigns 4e to wlan1, but I don't know what eth1 gets. Not a big nuisance though.
All in all, I think the ticket can be closed and #14563 as well.

I checked again and it turns out my memory didn't serve me correctly. Here is the mac address layout for stock firmware version 2.06EU:

lan 4d
wan 4e
wlan0 4d
wlan1 4f
