7800DXL needs manual recovery from dropped connection

Post by judge63 »

My 7800DXL was rock solid for about 18months, but over last few months it periodically loses the ADSL connection - PPP goes down, keeps trying to bring LCP back up unsuccessfully. ADSL is still in sync. Need to manually pull the cable from the wall, change the ADSL config, or reboot the router to recover.

Maybe a coincidence - around the time it started happening, there was some change in the exchange - now getting slightly higher upstream sync speeds than before - 780 now, was around half that before. Wonder if I am now connected to some different equipment which is not quite as compatible?

Not able to get any useful info out of BT support - sorry not a home hub - must be your router :(

Any ideas? Any config tweaks I can do to "force" an ADSL re-sync after PPP goes down?

Thanks.

Can you post a copy of your system log once the issue occurs??

will do - when it occurs. Could be day, could be a week or more...

Meantime I have got a script running. It is nice that there is shell access. The script should toggle the adsl connection if it sees the pppoa interface staying down for at least a couple of minutes (that's the theory anyway ;)

Problem has happened - and my script recovered it :)
Here is the log (the user.notice entries are from the script).
Does it provide anything useful? Thx.

pppd:LCP: timeout sending Config-Requests , means the router is sending LCP config requests to the exchange and the exchange is not replying.

Try setting your WAN connection to PPPoE

Re: 7800DXL needs manual recovery from dropped connection

Post by judge63 »

Gave that a quick try, but didn't come up. PPP complaining about some channel problem. I'll look into it more at the weekend.

Is there a known issue with BT exchange equipment which causes LCP to fail with PPPoA encap?

Thx.

Unfortunately pppoe did not help. Connection has gone down twice and has required manual recovery. Log has lost when it first went down, but can see it is looping trying to unsuccessfully restart, before finally I pulled the cable from the wall to recover.
