Hi all! I'm using OpenWrt trunk (r41296) with batman-adv (2014.2.0) on a TP-Link WR1043ND using this network configuration file: http://sprunge.us/SVCI as you can see batman is running on ports number 1 (eth0.3) and number 3 (eth0.4).

root@OpenWrt:~# batctl if eth0.3: active eth0.4: active

I connect this router via ethernet cable to another device running batman-adv (2014.2.0). Looking at the link quality with "batctl o" I noticed that sometimes the link quality is poor using a port and good using the other one port. The good and the bad port aren't fixed, they switch randomly, so I tend to exclude an hardware problem. I connected the batman device to port 1 (eth0.3) and laptop on port 3 (eth0.4) and the quality of the batman link changes from one boot to another:
