TP Link WA750RE range extender connects to Plusnet Hub One but no Internet

[#1]

Hi, Ive just connected my PlusNet Hub One and it works fine, wireless good, everything connects, internet good.

The only problem is I use TP Link WA750RE range extenders upstairs.

They connect to PlusNet Hub One fine, they have good wireless signal, but no internet.

This problem goes away when I reconnect my old router!

This is the same on both TP Link WA750RE range extenders upstairs!

Everything works as it should, just no internet!!

Any ideas?

PS Just tried my Phone as a hotspot and TP Links WA750RE work perfectly, internet and everything, so it must be PlusNet Hub One causing problem!!

I think I might have fixed it!

I had set PlusNet Hub One Wifi Channel from 6 to 10!

When I set it back to 6, everything worked!!

I don't know why!!

But fingers crossed!!
