Please can someone help?!
Recently changed from virgin to Vodafone and got a new router. Previously had range extender for the back of the house. Tried to connect it to the new router...seems to install all ok, solid signal light on etc but when you try to connect it using the wifi password it says it's incorrect.
Tried buying a new range extender (TP link) but same problem remains. Initial set up fine but when you clink on the _ext wifi it says password incorrect.
I've been on the phone to Vodafone who have tried numerous things but nothing worked and they don't know why it's not working!
