Hi.

Wondering if someone could help me with a setup issue. 

I was using a TP Link vr2800 modem router with my Sky broadband SR203, worked fine with no issues. The Sky router had not so good WiFi in the house (can't move the location) so swapped it out for the TP link. 

Just had Sky fibre (FTTP with cityfibre) installed the other day. The guys used the Sky SR203 router for the setup, it works but again the WiFi is not good. 

The question is how do I set the TP-link vr2800 router without using the sky router? Tried just unplugging the cable in from the sky router (port 4) and putting in the tp link router (port 4) but it doesn't work.

Any help would be appreciated thanks.
