I have two ASUS RT-N66U devices, both running shibby's build 1.28.0000 MIPSR2-104 K26 USB VPN-64K. They have a WDS link set up between them on the 5GHz band (no AP functionality on this band).
The issue I am seeing: whenever I make certain config tweaks or reboot one of the routers, the performance of the WDS link is pretty cruddy (<25Mbps). What I have to do then is go into each router and do the channel scan on the 5GHz band. Once I do this, the WDS link performance goes up to its full speed (>170Mbps).
Maybe this is something that can be fixed in the firmware. If not, is there a way to set up a scrip to run as a scheduled/startup task that does the channel scan on the 5GHz band?
