Hello,
I've been using ubuntu for a few weeks now on my desktop and want to move it to my laptop, however I'm having problems with wireless networking. I have a toshiba tecra m2, the wireless chipset is an Intel 2100.

On starting ubuntu (the latest 606 version) it finds the card fine, it finds my SSID of my router fine and I can contact it (giving it a static ip lets me ping myself ok), and the details of it (iwconfig and the network details page via ubuntu) seem fine.

However, it cannot reach my router. I've tried assigning a static ip and putting the details of my router, but that doesn't do anything. I've also tried leaving it on DHCP and on calling 'ifup' it gets as far as doing a dhcp discovery but fails I think.

Everything else works fine (including wired ethernet) and I'm sure as far as I can see it is doing wireless ok, I just cannot make the switch from Windows until I can get wireless!

Anyone got any suggestions? I've tried various values with iwconfig but nothing seems to do much. On the network setup window, whilst it is activated the network status window always says 'disconnected'.

Thanks.

I've configured my wifi on my laptop yesterday, I'm a newbie too. So don't blame me if this sould too much evident.


Does your two interfaces (wifi and wired) are up at the same time ? I've got a problem similar to yours. In order to enable the wifi, I did ifdown on both interfaces, then ifup to the wifi interface.

Hello,
Yes I've tried disabling the wired ethernet.

Here are the various settings and outputs I've had.

1. This is the response if I set up the network using DHCP:
2. Here are the contents of /etc/network/interfaces when I use static ip
3. Here are the contents of what iwconfig and ifconfig produce
If anyone could help, it would be much appreciated.

Neil.

What does iwlist scan output ?
