NTE5 - extensions not working for broadband

Hi Guys

Just had Openreach call round to test the line after a fault at the exchange and they replaced the master socket so they could more easily test the line.

The only trouble is, my router will now only work at the master and I need it yo work on an extension. Phones still work on extensions.

Wiring as follows :

Long white short blue to 5
Long blue short white to 2
Long orange short white to 3

Long brown short white to B
Long white short brown to A

Any ideas how to get broadband through extensions would be appreciated.

Does the master have an adsl and phone socket on it now?

In reply to a post by blackpool:

Long brown short white to B
Long white short brown to A

Are these the ones on the extension cable, if so check the colours connected at the extension end, they should be the same
