TP-Link WDR 4900 - 5GHz Wifi Problems with CC

Description

I'm experiencing wifi problems with my TP-Link WDR 4900 running OpenWrt Chaos Calmer.

I have a properly configured /etc/config/wireless. But the wifi doesn't come up, LUCI displaying "Wireless is disabled or not associated", at the same time offering to disable it (sic).

I don't really know what is happening there, deleting the entries in the config file and re-adding it didn't help. Please tell me which logs to post to provide further information to investigate this issue.

Thanks.

The 2.4GHz wifi is working properly, only the 5GHz wifi has these issues.

please double check if you have set the correct channels.
on the 4900 the first radio0 is 5ghz, the radio1 is 2ghz.
if in doubt, post output of 'uci show wireless'.

I don't see any problem there, do you?

first try setting a channel instead of using 'auto'.
(first = 5ghz, so try 36 - 2n radio = 2.4ghz - so try 1)
any difference?

I have same problem. I did what you said and nothing.

There are no problems with the wdr4900 on recent DD builds. Just compile and install a recent DD version of openwrt and you have your problem fixed.
