Ubuntu 7.10 Networking Problem


I just finished installing a dual-boot of Vista and Ubuntu on my HP Pavilion. The installation went seamless, both Vista and Ubuntu both work properly, but I am unable to access the internet in the Ubuntu boot. I am on my vista section right now. I noticed that when I started Ubuntu it had "enable roaming" selected. I de-selected this and changed the configuration for dhcp, but no luck. I even tried switching the connection to static and manually entering my IP/DNS/Gateway information, but still... no luck. Any suggestions?

Are you attempting to connect via a wireless nic? (If so, which one?)

How do you connect to the net - dialup with a modem; using a cable modem; DSL with a router connecting use a cable; router with wireless?

Assuming it's some sort of network card, what type of card is it? There are a few fairly command brands which require a bit of fiddling to get them to work, although many should just work out of the box.

I'm connecting via nic to router to cable modem. I've tried to do a little research about my question, and I've noticed that a lot of ppl attempting dual boots have the same problem, but I've found no solutions. At one point I had Ubuntu 7.04 installed as the only OS on my computer and it automatically configured everything without a problem. It just seems weird that it does not pick up any settings at all when Vista is running perfectly fine on the other partition.

I don't think dual booting is the problem, unless Vista is somehow setting the card state in a way which makes it impossible to use with other OSes, but I've never heard of that with a NIC. What sort of card is it (manufacturer and model and/or chipset)?

I found the problem online (thk god for the internet). I guess that when you shut down a windows machine the ethernet card gets turned off, so that when you boot into linux it is disabled. The way to fix this is to shutdown the computer, unplug it from the power source, let it sit for 15sec. or so, and then boot into the linux distro (in this case ubuntu). I lost the link to the article, but it works.

Thanks for your help guys

Well done... what you describe is quite an old problem.

I've not seen it in a while.
I think you can change the nic settings in your bios so it won't sleep. Avoids having to do a complete power-down just to get network up again.

Hi,

Can you give some links to the solution (or problem description), please? I've a similar problem with a WinXP/Ubuntu install: If I hibernate in Windows, then I get no network in Ubuntu.

Thank you in advance!

I honestly cannot find the article, I just spent 10 minutes trying to find it again. I do know it was a link out of the gentoo linux forums. The problem is mainly with RealTek 8139 (and a few other models) Ethernet cards. I suppose when windows shuts down it turns off the ethernet card, so when you boot up into linux the card is still shut off. I think you can edit this in your System/Device Manager utility, or also in the BIOS (thanks Simon). Otherwise your other option (unless they come up with an updated driver) is to completely shutdown the computer, unplug the power source for 15 seconds or so, and boot up directly into linux.

Hope this helps...

The answer is (probably) in post 12 of this post: http://www.linuxquestions.org/questi...roblem-591466/

So, if you are dual-booting, either do a complete power-down (unplug laptop battery, unplug PC) or as dresb says in that post:
Quote:
Boot on windows.
Go to the device manager and get into "properties" for your network card.
In the "Advanced Options" tab select:

Wake-on-lan after shutdown | enable
Reboot into linux. Your network card should be working.
The second method looks easier in the long-term.

Thank you both. I'll try it once at my place (yes, it is one of those Realtek chips).

Regards!
