Re: Cannot connect during mornings
I picked up a 4100b, and am still unable to connect. I have tried swapping cables, filters, ethernet cards (computers), and modem. Best as I can get with the 4100b is the power, ethernet, and DSL lights lit steady green. The activity light flashes on once every 15 seconds or so with one computer, and will flash maybe three times every 15 seconds or so with the other computer. Normally PPPoE is run on the computer. The pppd log says "Timeout waiting for PADS packets". (I'll do a search on PADS next.)
The 4100b's diagnostic pages report the following: 3008 kbps down / 512 kbps up, software 1.0.0.63, SN margin 26.0dB, line attenuation 13.0dB. The modem came configured for hosting PPPoE itself, and in that case all four PPPoE test items were reported failed. I then changed the configuration to having PPP hosted on the computer, and it didn't fix things. |

| So you are getting a PPPoE authentication failure? Your SN Margin and Line Attenuation look fine. I had a similar problem a few months ago,it turned out to be a bad card in the RT that serves my area. My neighbor also had the same issue. After they(at&t)replaced the card,the problem went away.

| I don't recall authentication failure being in the error messages. The messages had to do with PADS and other usual diagnostics. (I'm not in front of the log right now.)
Thanks for mentioning their hardware being a possible factor. I'll try to look into increasing timeout values on my end, and if that doesn't help, I'll post AT&TDirect. |
