I have it configured as a WDS repeater, but this only works when the channel is set on the main router (a bt home hub 5 also running openwrt) and repeater to 36 (a non DFS channel). When I set the channel on my main router and repeater to "auto", and it selects a DFS frequency, the second interface on the repeater doesn't enable, and I have a lot of errors in my system log that say:
daemon.warn hostapd: Failed to check if DFS is required; ret=-1
Is there any way to fix this? The only non DFS channel my router works on is 36 and it's congested where I am.
Second what @anon4457646 said, i have a wrt1200 and from everything i've read the dfs implementation is pretty poor on the new wrt series, i've never had a dfs channel work on mine, wds or otherwise.
