Hi

Triple boot : Windows 7, Natty-11.04, Mint-12 :

In both Natty and Lisa network connection suddenly drops with a message at top right. This happens very frequently in both the Linuxes. Modem blinks, DSL cable etc are fine (India). All updates are applied regularly. This happens during download also. I use UGet (my experience tells me it is the only downloader on Linux with aria2 enabled which can stand up to IDM).

Very rarely this happens in Windows. Even if it happens windows quickly redials and connects.

But in Natty and Lisa unless I restart, the problem is not solved.

I have tried a couple of forums but did not receive convincing answer.

Please suggest a solution.

Thanks.

They are Microsoft, it’s going to succeed. In three years they are going to have this thing on half a billion computers, so it will be out there. I have to say, I actually like Windows 8. I am not a Windows user. It’s probably the first time that I would use a Windows machine.

And you did not ask yourself why is my connection lost ?

This problem doesn't come from your OS, it comes from your connection.

Accepted. Is there any way / setting / tweak / install or uninstall by which I can overcome this problem ?

Here are some clues that I found. First of all, this problem occurs disregarding the OS (distro) you are using.
You run the update regularly, sweeping the possibilities that it comes from your software (no bug, malicious program, etc.).
Before you take the pain of doing these, have you try troubleshooting?

There are three possibilities that I can think of (I sort it from the easiest solution) :

• Router problem, try checking your cables (the easiest way, yet somewhat helpful although I find it pretty annoying )
• Driver mis-configuration, you would want to find identify your networking device (brand and model are usually enough) just in case; find in your package manager for networking utilities (if you are lucky, you can find the driver you are looking for)
• Hardware damage, the most frustrating problem; this one is out of my reach.

Hope it can help.

I forgot to ask, how old is your PC?

Very helpful. Here is the feedback.

All updates are applied regularly. I just updated handbrake to 0.9.6 (just released).
I faintly remember this problem began cropping up after I updated kernel to 2.6.38-13. Is it connected ? I did not have this problem before. This is new so that rules out hardware problems.

Hardware wise I have done all the things you have mentioned. I am comfortable with screwdrivers. There are no hardware damages.

The frustrating thing is: downloads stop midway and I have to restart and do it all over again.

PC is dell optiplex 170L with onboard intel graphics, intel network card and is atleast 5 years old.

Yike....ubuntu 11.04 on a optiplex 170L. That is going to be no fun at all.

Just because this problem popped up when you updated your kernel doesnt mean its not hardware releated. Did you update the kernel with both mint 12 and ubuntu 11.04?

There could be some issue with UGet and the kernel you updated to as well.

Mint 12 shipped with 3.0 kernel. Updates to kernel haven't appeared as yet. I installed mint as I heard a lot about it but I prefer to do almost all my internet work with Natty as I am comfortable with Ubuntu since 10.04.

So kernel has been updated only on 11.04. I have also been using UGet for a long time without any problems. I have also tried with aria2 plugin enabled/disabled in UGet without success.

About optiplex 170L: I am waiting for Windows 8 in a new PC. Till then I am stuck with this.

It may be a memory problem, I had one of the newer distros last week complain about not having enough memory with 1 gig. Can not remember for sure but was Mint or Ubuntu I believe.

I have 2GB. I have not received any memory warnings.

Does memory have anything to do with the network?

I doubt it. The same problem repeated today also (network drop, wait for a few minutes and reboot). I have installed four browsers - Chrome-FF-Opera and Epiphany. Uget is the only download manager I use. I am unable to understand whether it is software conflict or a hardware problem.

Browsers won't get into software conflict. Even if so, it wouldn't be relevant to your problem. I think it is hardware problem; either incompatibility, misconfiguration, or damage.

As I was typing the connection broke. One of my friends, a long time windows user suggested it was a Kernel problem. Ubuntu Natty-11.04 has 2.6.38-13 and Mint Lisa-12 has 3.0.0-12. Is this so ? If yes, is there any workarounds ? I request any person with knowledge of kernel to suggest a workaround.
