Parents ADSL modem/router will no longer connect to the net.

The error log simply fills with:

OAM loopback response not received on VCI 0/38

OAM loopback response not received on VCI 8/38

OAM loopback response not received on VCI 0/35

Nothing changed with the router, and tried new cables and filter. Been ranting at Pipex's support (guess where located) for my dad who's sick of them. They're blaming the router, but the logs dont even get to a handshake - which is where they say it fails as invalid user credentials.

They're saying it passes all their line checks, although I know the basic tests ISPs have direct access to can easily give duff info as had the 'everythings fine' on a non working line myself! Only the BT openreach tests actually mean anything

I know if this is the case the routers DSL light goes red, as it was my router previously and forgot to reprogram when I first gave it to dad

Any one any idea's whilst I await their escalation to BT/UK personnel?

If the router is duff, then I think I'll use this to migrate away from Pipex/Tiscalli and to something else for them.

Try resetting router to factory defaults... also try changing microfilters

Tried filters, and tried a reset also. :(

Know it might sound daft but have you changed the phone cable from the modem to the filter. A friend of mine had similar issues and changing the cable worked fine for him

I havent, as the cable isnt moved so thought it couldnt be damaged - especially after 2yrs.

If the advanced line test comes back normal, then I'll send dad a spare router the in-laws have. But I think he's now mindset on leaving.

I'm assuming that nothing has changed in the house including the addition of a Sky box or a new phone on a previously unused extension? If that particular error happens all of a sudden with no other changes it usually means there's a cable fault - if it's always happened then it can mean that that the modem isn't using the appropriate settings for the ISP or that the firmware is duff as suggested above, but it would never have connected if that was the case. I'd get that spare router on first, as you'll get asked to do try that at some point and it's good to be forearmed

As you know, the standard line test just checks for some degree of end-to-end connectivity - a line can be pretty much dysfunctional for broadband and still pass the test, and the Openreach engineers essentially used to run the same test but could also pull a chunk of data from a BT test server to verify some quality of connection. I know there were changes in the way they were forced to work though so that may no longer be the case. You'll also get the threat of being charged £90 or so if they can't find anything wrong, which is of course a con as most of teh tests simply aren't looking for the rights things.

I'll get the old router and cable dug out, program it up, and report back.

I can understand your issues with pipex support, seeing as though its now run by Tiscali using their support staff.

TBH though, it does sound like a router problem. After resetting the router, I assume you have re-entered the username and what you are sure is the correct password.

Pulled the router config apart and reprogrammed.

Sending a spare router I've set up just to be sure.
