Network disconnects after minute Dell Dimension 8200

[wowfunhappy]

Hello. My family has an old Dell Dimension 8200 which has become incapable of running Windows at decent speeds. I was hoping to install Linux as a solution.

However, not being all that computer literate, my family needs a simplistic interface. My hope is to use the Moblin UI. Because Moblin doesn't support the computer's processor, I'm hoping to install the UI on top of OpenSuse 11.1.

I've successfully installed Opensuse on the computer (I haven't attempted to make the Moblin UI work yet). However, I am having problems with the internet connection.

The computer uses a standard Ethernet cable to connect to the internet. Opensuse however is not able to see this connection unless I unplug the Ethernet cable from the computer and plug it back in. After doing so, the internet works perfectly for about 1 minute. After that, the connection will stop working again unless I, once again, unplug the Ethernet cable and plug it back in.

Obviously, unplugging the ethernet cable every minute or so is not practical for general use. Can anyone offer any assistance? If you need me to post the output of any terminal commands, tell me what commands and I'll do so.

Thanks!

Become root in a terminal with

su

and post the output of

lspci -vnn

Maybe, but a modern linux distribution does not have lower demand for RAM/CPU than a 7 year old Windows (XP), on the contrary.

Windows XP runs with 128MB of RAM (and it will do quite nicely if configured in the respective way).

An openSUSE under 256MB of RAM will be not a lot of fun, perhaps with moblin (don't know its minimum requirements), maybe with fluxbox or some other, slim WM.

If you were not able to strip down Windows XP to run with low hardware specs, I doubt you will be happy with openSUSE 11.1 (or any other "big" linux distribution).

[wowfunhappy]

The computer used to run Windows 2000; Windows XP didn't exist when we bought it. It's specs aren't THAT bad though. When we first got the computer, it was one of the most expensive computers you could buy.

I'd like to try installing XP, but I don't have a spare copy. And while Windows 2000 SP1 and SP2 work fine, my father is worried that without SP4 there's a large risk we'll get a virus.

It has 512MB or Ram, so more than the 256MB you said are needed.

I'll post the output of lspci -vnn as soon as I get a chance later today; thanks. Do you want me to run it during the minute the internet works, or after it disconnects (or both)?

[Akoellh]

512 MB is plenty, even for KDE (3.5 for sure).

And instead of lspci -vvn which will give a lot of (in most cases) useless information but missing a lot of useful one, read this.

openSUSE Forums - View Single Post - Getting Your Wireless to Work

BTW:

Win 2000 has certainly lower requirements than XP, so I would bet it is a configuration problem and not "weak" hardware.

[wowfunhappy]

Akoellh, if the script is absolutely necessary, I'll run it, but please understand that running scripts takes slightly longer than running a command, and when your internet is constantly disconnecting from the computer you are working on, slightly longer becomes a lot longer. I don't know how good this constant unplugging and replugging is for my ethernet port.

Here's the output of lspci -vnn when the internet is working:

Thanks again for your help anyone. Again, I can run those scripts if I need to, but for now, running these commands means a less constant running to the back of the computer.

[67GTA]

You need to be using the dmfe driver instead of the tulip driver. I think once you blacklist the tulip driver and reboot, you should be fine. Look in /etc/modprobe.d/blacklist.conf to make sure the dmfe module isn't blacklisted and add

blacklist tulip

The lspci command is fine in this case because I was almost certain what the output would be, and I've had experience with this PC model.

[wowfunhappy]

Sorry... I once used Ubuntu as my main desktop OS but after half a year of not using Linux I've started to forget stuff...

how can I edit /etc/modprobe.d/blacklist.conf? The file is only accessible when logged in as root. When running as root, I'm not able to start the gedit program that I need for editing text files... sorry if it's a noob question...

[67GTA]

I remember seeing a bug a while back about apps not opening as root. Try becoming root with

su -

and then try gedit.

[wowfunhappy]

Okay, that worked, I was able to open gedit as root.

When I opened blacklist.conf, it appeared in gedit as a completely blank document.

Not sure if that's part of the problem, but anyway, when I typed "blacklist tulip" into the file, saved, and rebooted, the problem was even worse. Instead of connecting to the internet and disconnecting a minute later, my computer wouldn't connect at all.
