Slow network when NetworkManager manages a PPPoE interface defined in /e/n/i

[ebrahim]

I have searched many websites trying to find the solution to this problem. I tried such things as disabling IPv6, reconfiguring Firefox, etc... But I could not solve this problem. The problem occurs in each new version of Ubuntu and never gets fixed.

You can see some of my efforts at (http://forum.ubuntu.ir/index.php/topic,22957.0.html) and ( http://tinyurl.com/9ekhmm5 ) and many other people that mentioned this problem at http://ubuntuforums.org/ ...

Description

When I use pppoeconf in a terminal to connect to the Internet, every time I get this warning (in the terminal):

WARNING: ifup -a is disabled in favour of NetworkManager.
Set ifupdown:managed=false in /etc/NetworkManager/NetworkManager.conf.
Plugin rp-pppoe.so loaded

After I fixed this warning (by changing true to false), my Internet speed in Ubuntu has been working such as win7 without any poor perfomance; and when I restore the value to the default the Internet speed is very slow.

Some of information about the case where managed=true:

I have hp2170 laptop, have been using Hotspot(wireless)-128 kbps bandwidth (rise to 1 Mbps at night) from my local ISP, installed Windows 7 64-bit and Ubuntu 12.4 32-bit (in addition to WS08 R2-Backtrack 5-Fedora 14-Windows 7 32-bit) .

99% of the time I used those operating system for web browsing and download; I could connect to the Internet very well with no errors but as mentioned before I measured Internet speed.

In Ubuntu 12.4 64bit:
firefox (v 11):download speed:max 28 kbps
open page speed:very slow

chrome (better than Firefox):
Open page speed:very good
Download speed:max 80 kbps

And synaptic package manager download rate: max 40 kbps

In windows 7 64bit:
Firefox 15.1
both download speed and page speed:very good
download speed:min 110 kbps (with IDM)
please consider the max and min download rate.

I tried to make the title more descriptive, but please correct it if I have misunderstood.

[Marius B. Kotsbak (mariusko)]

But why do you manually manage it? What happens if you stop using pppoeconf in the terminal and configure the ppoe connection in the network manager options instead?

@ Marius: I love terminal and did not configure the ppoe connection in the network manager options ,but i am going to do it.

[Marius B. Kotsbak (mariusko)]

Good, i think you either should use Network Manager fully or not at all (stop it).

[ebrahim (taheri-113)]

hi

I create ppoe connection in the network manager options( for example "test") then in terminal:

sudo pon test

(shows):

the file /etc/ppp/peers/test does not exist.please create it or use a command line argument.

 i am not sure what it means by "Plugin rp-pppoe.so loaded" in the warning.

[Marius B. Kotsbak (mariusko)]

Please also connect to this connection through the Network Manager menu.

[ebrahim (taheri-113)]

sorry:

it does not appear in Network Manager menu so i must used the terminal.

[ebrahim (taheri-113)]

hi all

happy new year

yesterday,I installed Ubuntu 12.10 completely without any errors,but in the first effort to connecting to the internet when typed pppoeconf command in the terminal, said:
"Plugin rp-pppoe.so loaded"
 I didn't any thought.

thank you

[Marius B. Kotsbak (mariusko)]

Please add a screenshot of the network manager dialog where you are not seeing ADSL config options.

[ebrahim (taheri-113)]

thank you

I'm not sure what you mean by the command especially "... where you are not seeing ADSL config options." but try to take screenshot.

I took some screenshots such as:

This bug was marked Incomplete some time ago and was supposed to autoclose after 90 days. I'm going to close it manually due to no activity (and likely the issue has gone away/been fixed).
