The problem was the same on his computer and my laptop. I reset his router (Home Hub v 3) and tried it in the test socket to no avail. The router stats were (superficially) very good indeed. I tried an alternate DNS server and that did not seem to help. The router could be faulty but this was his second one, supplied because the problems arose with the original Home Hub. And at that point I ran out of time and ideas.
The only thing I know of that might cause this type of problem is a MTU set badly off - but I reset the Hub (end of a paper-clip down the hole) which should have restored the correct value. So the only thing left that might be faulty would be the new ADSL2+ line card in the telephone exchange - which fits with the timing of when problems arose. But what sort of a fault could produce this sort of phenomenology?

On the subject of trying another router, I have noticed that my router (i.e.using my Plusnet credentials) will connect to my Plusnet account on any broadband line in the area (all on the same telephone exchange). Does that open up possibilities for additional testing?

Quote from: jelv I'd be very surprised if you can connect on any line
Last week I went to see someone who uses TalkTalk - which is supposed to be LUU in my area. Plugged in my own router and it had established a connection to Plusnet before I had a chance to change the settings. Also done something similar on Orange. So although the stats aren't enough to truly say it is any line, it certainly is not confined to other Plusnet lines.

Quote from: itsme were you issued with a Plusnet IP address?
Good point; I did not check that.

Do a factory reset on the current router and put in credentials only.
Check whether your login is on plusdsl or plusdsl2 on your login - when I had ADSL2 issues we found that Plusdsl2 had issues at Plusnet it was not the total problem but it did affect it.
For NSLOOKUP you can type NSLOOKUP /? or just NSLOOKUP and then type ? then Enter key for even more detail.
DNS is in the PC too so try changing the lan card settings.
One sure fire way to stop bad resolving of internal networks is to change the subnet to a totally different one and change PC's to automatically get IP and DNS, if these are static you may have issues.
If running Win7 then the definition of the network as Home, Work or Public can affect it
TraceRT will help too because it can show any weird paths, also some trojans disable Google or put in an alternative IP in your Hosts file, hopefully you are not running windows as an Admin, otherwise you are wide open.

Is there a way to view a computer's DNS cache so you can note down some cached entries to see if they are wrong?
