We had a spike yesterday when a submersible pump tripped the main circuit
(RCD) in the consumer unit.

Every thing came back up OK when reset ( including the LL phone) except
the internet connection.
I have tried the following:-

1. Swapped out the ADSL router with a spare.
2. Swapped out the cable from BT wall socket to router with a spare
3. Swapped out the face plate (with integral filter) to the BT socket with
a spare.
4. Tested set up with two different PC's and 2 laptops.

Any suggestions?

So what happens lights wise on the router ? Do you get both the adsl and
internet lights up ?

If you dont get the internet light up, likely the isp has locked your
service out.

If the adsl light doesnt come up likely something broke behind the BT
socket
but thats very unlikely given that the LL still works. Usually if anything
the LL
doesnt work because there is no dc path anymore but adsl still works
because
it doesnt need a dc path. Its theoretically possible you could have killed
the
dslam port back in the exchange, but very unlikely.

A) The DSL light is showing steady green.
b) The 2 WLAn lights are doing a steady regular flashing as per normal.

You need several layers of connection from the router to get functional
broadband service.

First you need DSL sync, which it sounds like you have. The router will
report uplink and downlink speeds, line attenuation, and error rates etc.

Next you need a working PPPoA connection to the ISP - so basically
logged into your account with the correct username and password. Once
that is right you should have an IP address and access to a default
gateway. The router should be able to confirm all that.

Next you need working routing. So from a command line on your computer
you should be able to ping the ISPs default gateway, or something on the
wider internet. For example "ping 8.8.8.8" will check you can get a
response from Google's DNS servers.

Lastly you need working name resolution. So for example if the above
ping works, but ping www.google.com does not, then that suggests is
actually the name lookups that are not working.
