I'm trying to get 8.09 running on my dg834v2. Everything works great except for the DSL. If anyone has any thoughts about how I might get this running I'd really appreciate it.

This is the problem:

Oct 23 08:30:58 OpenWrt daemon.warn pppd[781]: Timeout waiting for PADO packets
Oct 23 08:30:58 OpenWrt daemon.err pppd[781]: Unable to complete PPPoE Discovery

I've installed kmod-sangam-atm-annex-a (definitely the correct annex) and br2684ctl (and I've enabled br268ctl).

Here's my opkg list:

And here's my /etc/config/network (note that the gateway and dns options are to enable connecting through a second dg834 that has the original firmware so that I can download packages with opkg):

Any thoughts?

For what it's worth I've read everything that the search turns up for PADO and DG834 DSL without finding something that might explain why this isn't working.

There's should be a line saying DSL in sync, but you don't have it, that means that DSL modem has not synchronized with DSLAM. Double check nas0 parameters.

It turned out that the problem was that I had not set the adam2 modulation variable. After I set the variable to T1413 the DSL was able to sync.

well, i can not sync anyway ... Seldom when the modem syncs , it get synced for a few minutes and the dsl goes out of sync... and never sync anymore... SNR margins are over 15 ... i have no idea why this is happening... everything is ok using netgear firmware. Any help ?

The discussion might have continued from here.
