Help with wireless bridge

[Mike Daniel]

I have tried this on several occasions and have never got it to work.  I
have tried using Fedora Core to bridge between my wireless AP and Ethernet.
It works fine doing Ethernet to Ethernet but when I add the wireless, it
does not work.  As I recall, it forwards the traffic but it my wireless
gateway does not forward the traffic from the Wireless to the Ethernet ports
on the gateway.  It would be nice if it would work, I could extend my
Ethernet to another part of my house.  I am waiting to see if Linksys comes
out with a fix for this (I have a linksys wrt54g).  I have not tried it
since they came out with a new version of the firmware.

Hi
Can anyone either help or tell me a better place task for it. I need help
setting up a

<http://www.experts-exchange.com/Networking/Linux_Networking/Q_20957382.html
> Windows XP PCs. I want to extend this network wirelessly to my Dell
Centrino portable.

I reconfigured the kernel with wireless and bridge support and installed a
generic 8180 wireless card using ndiswrapper. I have configured it so:
iwconfig wlan0 channel 1
iwconfig wlan0 mode Ad-Hoc
iwconfig wlan0 essid any
ifconfig wlan0 192.168.1.10 broadcast 192.168.1.255 netmask 255.255.255.0. I
have copied the output from ifconfig and iwconfig below. The portable now
detects its presence so the card must be working OK.

I think I want a simple bridge which just sends/receives packets from eth0
to wlan0, no fancy tricks. But if I create a bridge like this:
Brctl addbr br0
Brctl addif br0 etho
Brctl addif br0 wla0

then it doesn't work and the network stops. What do I need to do?  (I know I
need to add encryption and change the ESSi later for securit reasons

Thanks in advance Andrew
