DFS UK 5ghz channels

Hi all,

 

My next door neighbour uses channel 36 on 5ghz, I set mine to channel 100 but noticed that every day when I come back on to check it has changed the channel to 36 or 48. So today I have changed to channel 60. I don’t live near an airport so I’m wondering what’s triggering it. By moving away from 100 down to 60 which is still a DFS channel will I have more of a chance. 

 

Do 5ghz AC 80mhz channels overlap on the non DFS channels? 

 

Thanks

In the US, no, 80 Mhz channel is either all inside or all outside of DFS.  See http://duckware.com/wifi#6g

 

See https://en.wikipedia.org/wiki/List_of_WLAN_channels for channels in UK.

 

The best you can do is just keep trying different channels until you find one that you don't get bumped off of.  If you get bumped off, that means the router has detected some 'radar' or similar signal (it could be military)

Lots of things will trigger this. 

The above link shows that channel 149 should be available. Router may not though. Depends on router probably.

If the below reference is correct, I would try channel 138 because the maximum power is 1 W rather than 200 mW.
