TP-Link 4900 V1 using DDWRT 23320

Hi,

I've been using various versions of the above firmware and so far if i change beyond 21676, it seems that the 5ghz wifi channel goes slow, so anything connected to it struggles to get internet access. If i revert back to 21676, all is well.

Any suggestions as to what is wrong or what setting i may need to change?

Thanks

Darren

ok, attached a copy of the settings when on 21676.

I don't have the advanced settings ticked. When i flash to a later build i've not changed any of these settings. The only change i have had to make is to a command file in order to get the router to connect to my sky fibre account.
