Ubuntu 8.10 and Vista, crippling network card?

Hi

I decided yesterday to install Ubuntu 8.10 on my laptop to check it out, the installation went flawless and the bootloader was fixed automatically.

The problem however appear to be that the network on the laptop does not work anymore.
This problem goes for Vista and Ubuntu.

I am able to connect to any wireless network with Ubuntu, but i am unable to get internet access.
Other machines using the same wireless have no issue.

Vista however is unable to connect to wireless networks, claiming that it does not recieve a response from the wireless router.

Cabled network are a different matter, i get local area only, but i am connected.

Computer: Toshiba Satelite L40

NIC: Realtek RTL8139/810x Family Fast Ethernet

WNIC: Realtek RTL8187B Wireless 802.11g 54Mbps USB 2.0

--------------
Before i installed Ubuntu, i was able to access the cabled and wireless networks without issues.
I have now tried in three different wireless networks in both OS's
and 2 cabled networks.

I haven't found anything in google that indicated anything on this.

Edit:
Reinstall of hardware and updating BIOS made Vista able to connect to wireless networks, Ubuntu still cannot access internet, but can still connect to the wireless networks.

 

I would wager that it is the router rather than the computer. Settings in ubuntu do not have any affect what so ever on settings in vista and it is extremely unlikely that you simultaneously hosed both. I'd go through the normal steps for resetting the router and see if that helps.

I'd also bet that you are able to connect to the internet, but you do not have a DNS set. This could also be due to a problem with the router, the other computers may work fine because they got their DNS settings via DHCP before something on the router screwed up.

 

Were you able to connect to internet via Vista before you installed Ubuntu 8.10?

 

Try going to a coffee shop or someplace with public wireless. Does it work there?

 

Yes, i was able to access internet on both of the wireless networks (one at work and the other at home) using Vista before Ubuntu came along.

and i am able to do so now as well after reinstalling the wireless card and updating Bios.

Ubuntu however does connect to the wireless but does not allow access to internet.

There are no proxies in the networks.
Ubuntu clearly states that i am connected.
I have DNS listed, Ip-adress and subnet is ok.

Using cabled network is ok now.

 

Actually, there are no "other" computer, it is a dual boot, all installed on same machine, different partition of the HDD

 

yes, as stated at the end of my first post:

Hi,

I cannot help you with Windows, but I can probably help you figure out what is going wrong in Ubuntu. When you are wirelessly connected to the network, issue the following commands in a terminal:

Code:

ping 209.85.171.99

If that works, but

Code:

ping google.com

doesn't, type this command:

Code:

host google.com

and let me know what happens.

If the first command (ping 209.85.171.99) didn't work, do this:

Code:

traceroute 209.85.171.99

and this:

Code:

ifconfig

and post the output of both here.

If the first command did work, it's a DNS problem, so let me know what brand/model router you have.

 

Do the Windows drivers provide a diagnostic tool? In addition to telling you what's wrong, they might even fix the problem. You might have to download drivers from Realtek to get any tools, as the ones from Windows Update and system manufacturers sometimes strip them.

Thing is, this happens on all of the wireless networks that i access.

With windows Vista on the same machine, i am able to access internet through the routers.

I'm starting to wonder if Ubuntu just doesn't cope with my wireless network card.

 

EXACTLY THE SAME PROBLEM ON MY TOSHIBA A 210 LAPTOP WITH THE SAME CARD!!! happy that i am not alone... i think theres something wrong with network manager in ubuntu 8.10.. i uninstalled it and installed Wicd... i could get on the internet and load the pages quite fast, but still it wasnt that good as in Vista... My problem is also, when i connect to a wireless network in ubuntu a i cant connect to any wireless network in Vista when i reboot... The only way how to fix it is always shut down computer!!! and than again turn it on and than it works in Vista... I read many many times that ubuntu cant affect Vista, but i am not 100 percent sure now... i updated bios, reinstall Vista, reinstall Ubuntu, updated drivers in Vista, did everything what i could but nope.. nothing has changed!!!

 

This Ubuntu thread suggests that the Realtek 8187B driver in the latest release kernel, 2.6.27, which is part of Ubuntu 8.10, corrects some problems with running this WiFi hardware under Linux. However, if you read toward the end of the thread you can see others having similar problems to yours, and are pointing the finger at the Networkmanager program. So one solution for now seems to be;

Hopefully an update to Networkmanager in the future can address this problem.

Good Luck..

 

same problem...i have got only wi-fi...no other option like cable etc....what to do???
