Not really related to Faster Internet, but the Wansford exchange does seem to be having a rough patch with faults. I have had three cases, and an Openreach engineer confirmed several others, where a user can't get onto the Internet and their router has a solid DSL connection to the exchange.
The symptoms of this are a solid DSL light showing a good connection, and a sensible speed displayed in the router's web pages. The Internet light will be off, or red instead of green, or Amber instead of Blue on a BT Home Hub. The router web interface will show no IP address, there may be an error like Authentication failed, No PPP session, LCP down or similar.
If you change the router login to bt_test@startup_domain the above symptoms persist - you can't even log in to the test user (which needs no password and should work on all lines).
So if this happens call up your service provider and tell them you have a good ADSL signal but no PPP session, that the bt_test login doesn't work and that some of your neighbours had the same problem and BT Wholesale had to make changes at the exchange.
Most "help"desks will have you changing filters and monkeying around with all manner of things, but you either need them to report it to BT Wholesale or get them to arrange an Openreach engineer visit who will then have to do the same. Don't be put off by threats of visit charges, if you have an ADSL signal with 448k upstream and a sensible downstream speed then it isn't a problem with the phone line or wiring.c
