slow speed using pppoe connection on Ubuntu

Asked by Maris Radu

I have a Compaq Presario CQ61, instaled Ubuntu 9.10 and Windows 7 on it.
It works great except the PPPoE connection in Ubuntu, when i dial in Windows my download speed reach up to 91 Mb, rebooted in Ubuntu, downloaded same file from the same server with a speed of maximum 3 Mb, cheked in Windows again 80 - 90 Mb constant. I can't figure what slow's the internet connection in Ubuntu, I don't have any modem or router. I am using PPPoE directly from my PC. I instaled Fedora 12 (64), this works fine and the speed reached 85 Mb, Upgrade to Ubuntu 10.4 but the speed is the same, a max of 3Mb on an 100Mb internet conection, that works on Windows and Fedora, but not on Ubuntu.
(NO iptables configured, NO HTB, CBQ ...etc configured) .

Anyone has any ideas on what should I do ?
 Thank you

@tjpmack2 > I don't see anything about speed in the link you provided, just how to set up the connection, but like I said, the connection is set up and worknig, but it is slow ( max 3Mb ). It should reach up to 100 Mb in theory, practicaly I reached up to 96 Mb using Fedora Core 12 (64), and 91 Mb in Windows 7.

The windows speed is of no interest to us. It is a different OS with different support. However the fedora info is very useful as it is the same OS, Linux.

I don't use PPPoE but is it possible to export the config from fedora to then import into Ubuntu? I'd also log a bug

the config for the connection is simple and the same:

in file: /etc/ppp/dsl-provider
noipdefault
defaultroute
replacedefaultroute
hide-password
persist
user "example_user"
usepeerdns

Or do you mean the whole config of ppp package ( don't know if they are compatible, but if needed I will reinstall fedora side by side with Ubuntu, Fedora it's deleted now )

I logged Bug #610130: "Ubuntu slow pppoe speed".

The problem is in the Kernel module r8169 , I change it to module r8101 , and I reached a speed of 76 Mb.
