Ubuntu bridging wireless interface

Silvr · Post by **Silvr** » 28. Feb 2008, 03:15

I was trying to set up a Virtualbox to run WindowsXP under Ubuntu, on my laptop with a Centrino 2200bg wireless card. I followed the instructions in the manual. When I add the wireless interface to the bridge and restart networking, it shows a full signal in the NM icon, but it constantly asks me for my WPA key. I know I am typing it correctly. I have also tried changing it from auto to AES-CCMP.

I know that in the manual it says that it is not possible to set up a bridge wirelessly. I have searched and found a lot of posts from people that say that they have done this.I assume that the manual is outdated. Could someone please help me with this?

Hi,
I suppose you're using a WLAN router.
If you don't mind to use additional hardware you could use a WLAN USB stick and activate this USB device in the VB settings of your guest system.
Then install the driver for the device in your WINXP.
This solution runs totally separate from your Linux network. You could even use an USB stick that ist only supported in WinXP and not in Linux.
If it is supportd in Linux you have to unlaod the Linux driver with rmmod before using it in WinXP.

So there is no way to bridge a wireless interface with VB without adding another card?

Its really starting to irritate me now. This works for other people, just not me. I am starting to think that VBox is just not compatible with my Centrino 2200bg. This is what I did:

sudo sysctl net.ipv4.ip_forward=1
net.ipv4.ip_forward = 1
sudo tunctl -b -u zac
tap0
sudo ip link set tap0 up
sudo ip addr add 192.168.1.150 dev tap0
sudo parprouted -d eth1 tap0

Anyone know what I am doing wrong?

Wireless bridging like you would do with a Lan interface just isn't possible because of the limitations the bridge has. It needs additional options for wifi and it's never made for that. Try the following guide, it should work. They are still active in that topic, so any changes there might help you get it working if it doesn't.

That is my thread also. You are correct. I was originally trying to created a bridge. Then I found that it is impossible to do with wireless. I was under the impression the parprouted way would work, but it doesnt work for me either. I thought I would post here to see if anyone has got a Centrino 2200bg to work with wireless.

Oh, well, I do have a centrino, only the 3945 card. When I have some spare time, I might try it and see if it works or not.

I have the same results using parprouted, my wifi card is intel 3945 and I'm using Ubuntu Hardy.

I've had it intermittently work or rather partially working to see some of my machines on the network.

The man page for parprouted does say it was originally written for the 2.4 kernel and the original poster of that guide appears to have had it working under Fedora.

I need to guests to access the network and my machines on the network to access the guests preferably over wifi.
