Router is dropping connection every 3 minutes or so. Running latest firmware. Tried switching bands to the correct version for my carrier (O2UK) band 20. every time I log back on tplinkmodem.net it's reset to band 1.

Bought from amazon UK in March this year.

Current IPS version is 22042701.

Symbols on the front of the router are power, wps, wifi, signal strength 3 bars.

I've tried everything that's been said on other topics about it but I'm not 100% pc savy, so have no real idea on how to rectify the problem or whats needed.

All I know is it's annoying as and I'm about to chuck it out the window.
