This is for a uni project I'm working on.

I'm running jaunty on 2 machines both with wifi cards, one is a d-link pci and the other is a rtl8187 usb. Both cards are working properly. What I want to do is run an ad-hoc (peer to peer) wifi network from one machine that other machines can connect to and then with a bridged wlan0 eth1 be assigned ip addresses from the university dhcp server.

So far I have been successful in setting up the bridge and the ad-hoc network but I can't connect either of my ubuntu machines to it. I can however connect a windows box to it and it works fine, it gets assigned a dhcp address and I can connect to the uni network and the internet.

So my question is: why can windows connect and ubuntu can't?

Is there a better way to go about this?


This is my /etc/network/interfaces
#
auto lo
iface lo inet loopback

auto br0
iface br0 inet dhcp
bridge_ports wlan0 eth1
up \
/sbin/iwconfig wlan0 essid atxwire && \
/sbin/iwconfig wlan0 mode Master && \
/sbin/iwconfig wlan0 channel 10

This may or may not help your situation, but according to what you posted there, you aren't actually running in ad-hoc.

You have the card in Master, which is AP mode. Master mode is glitchy under a number of drivers however, so unless you absolutely need Master functionality (like if you had PDAs which don't support WAN over ad-hoc), then put the card into the actual ad-hoc mode. I have had a few instances where I was unable to connect some devices due to a buggy Master driver.

Yes I have since found that master mode is a problem. I asked a friend to look at it for me and he solved it by disabling the network manager and using ndiswrapper to install the windows drivers for both wifi cards and then configuring both devices in ad-hoc mode. It works fine now and both devices are allocated proper addresses from the uni's dhcp server.

Thanks for your help.
