Wired PPPOE Connection in Jaunty drops on DHCPREQUEST

[KT]

This is in Jaunty, but I had the same problem in Hardy, or almost exactly the same, even though I never troubleshot it then.

Symptoms are lost connection after at least a short break from using the internet, but its inconsistent. It might drop while I am away for 3 minutes, and might not drop if I go out for an hour. But it drops really regularly, as in 5 times a day if I am off and on the comp all day.

When its gone, not all connections are cut off, only new ones cannot be made. So I have had the interesting experience of chatting for an hour on skype with a great connection, while my browser and bit torrent or chat all cannot connect. Sometimes those legacy connections continue for a long time, like for instance on bit torrent.

I installed wicd some time back, which seems to be a bit better, but nm did the same thing.

When the connection is gone, 'plog' returns nothing at all, no data. A quick poff and pon will get the connection back, but sometimes it will quickly die again.

My syslog file seems to turn up this entry every time the connection dies (been monitoring for a couple days now):

Sep 21 22:00:08 krsh-desktop dhclient: DHCPREQUEST of 192.168.1.2 on eth1 to 192.168.1.1 port 67
Sep 21 22:00:08 krsh-desktop dhclient: DHCPACK of 192.168.1.2 from 192.168.1.1
Sep 21 22:00:08 krsh-desktop dhclient: bound to 192.168.1.2 -- renewal in 37547 seconds.

And then the connection is gone.

If any other info is needed, just let me know.

This could be a hardware issue, although I am not sure, but a friend of mine has precisely the same connection and modem, I believe, and never had this problem on 8.04 or 9.04.

I have a desktop and server machine connected via wired ethernet to a residential router. The desktop (Jaunty) would lose it's connection on a regular basis. I solved the problem by installing WICD and have now upgraded to Karmic and am still using WICD.

The Jaunty/Karmic server also loses its connection to the router every few days, with the log filling up with the same "dhclient: dhcprequest" entries posted above. I have restart the router and the server to solve the problem.

Hi I want to provide an update.

I got sick of this problem and went out and bought a cheap Linksys network card, put it in and disabled the onboard LAN, and problem was solved.

Then I installed 9.10, still all was good. And to confirm, later I moved my box and must have dis-lodged the network card, cuz my connection was gone. At that time I pulled out the network card and went with the on board.

And the problems came back. So I just put the network card back in, it wasn't broken after all, and I expect that the problem is gone again, will report back if not.

So, I have to blame this on the Asus mobo and on-board LAN. Hardware problem I guess.

The comp is HP a6405cn with these specs:

So this may implicate the Realtek RTL8101E 10/100 Mbps LAN, possibly? I dunno but problem solved anyway.

Just another quick update, bizarrely the same thing happened again, (plog returns no data), but just once or twice in the couple days after I switched network cards.

So that's weird. But only once or twice, and now all is well with my connection. Pretty strange.

Anyway this is probably the last update I will put up here. Maybe it will help someone someday.

And thanks to this board and participants.
