I am trying to configure my Wireless LAN in such a way that it can route packets from other nodes to a access points, so that nodes outside the reach of the access point can route their packets through my card. I understand that I need to put my card into Ad-hoc mode for this to work.

However, # iwconfig eth1 mode Ad-Hoc # service network restart fails to look up IP information for my card. DHCP is configured in the network. I have tried to put the card in Auto and Repeater mode too through iwconfig, with the same results. Funnily the configuration file at /etc/sysconfig/networking/devices/ifcfg-eth1 still showed the mode as Managed even when I had set it to Repeater. Manually changing the setting did not yield anything fruitful.

I am using Fedora Core 5, 2.6.16 kernel, and my card only supports 802.11b not 802.11g.

Any idea?

Ok...did you check whether your wifi card is binding with the other node? Unless it binds, it wont get an IP address.

How do I check that?
