Wireless Laptop as Ethernet Bridge

[allnightarockin]

I have a wifi a card in my laptop. I would like to take the signal i get from my wireless access point and connect my PS2 or my other laptop up to the internet/network through the ethernet cord on my laptop
So it would look like this
Modem>Router>Ubuntu WiFi> Ethernet/Cat5 Device

Any help would be appreciated..
I suppose i could bridge the connection between my wifi and ethernet cord but im not 100% sure how to do that..
i am semi-new to Ubuntu but i know the basics and a little bit more, so any hints you could give me would be amazing =]]

Thank you, and hope to hear back soon.

That shouldn't be too hard. I've done it once too.
You need to install bridge-utils. Then you'll have to do something like:

brctl addif br0
ifconfig br0 up

Delete the IP from your wlan interface and add it to your bridge interface, for example:

ip addr del 192.168.11.14/24 dev wlan0
ip addr add 192.168.11.24/24 dev br0
route add default gw 192.168.11.1

Now you've lost your network connectivity, and you have to configure the bridge:

brctl addif br0 wlan0
brctl addif br0 eth0

That should restore the connectivity _and_ add your non-wireless nic to the bridge. With this configuration it should be working. I haven't tested it, but it should go fine.

Good luck
(ofcourse you need to replace the interface names and ip's if their named/numbered differently)

Thank you for replying so quick Friek..

I had a bunch of stuff here but it doesnt apply anymore so i am just gonna edit it out =]

Please read next post though, im still having issues.

I decided to try and figure it out myself..didnt workout so well
br1= My bridge
192.168.1.147 = My Local IP


How i thought to make a bridge in BRCTL [Bridge-Utils]
you type

 sudo addbr br1

followed by

 ifconfig br1 up

followed by

ip addr del 192.168.1.127/24 dev eth1
ip addr add 192.168.1.24/24 dev br1
route add default gw 192.168.1.1

then

brctl addif br1 eth1
brctl addif brq eth0

Does this look correct?? it didnt seem to work for me, br1 became unrecognizable and i couldnt connect to anything

i fixed it by typing ifconfig br1 down.
then deleting the bridge in BRCTL


Do you know what could be going on??

My routing configuration after my last attempt (when i deleted it all)
Terminal:

Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
192.168.1.0     *               255.255.255.0   U     0      0        0 eth1
link-local      *               255.255.0.0     U     1000   0        0 eth1
default         DD-WRT          0.0.0.0         UG    0      0        0 eth1

Please let me know if you need more information. This would be so useful for me..
im just not 100% sure how to set it up

Hmm, the way I did it work alright. However, I now read that some wireless nics don't do the job. Read this site for some explanation.

Friek, many thanks for pointing this link out !
I tried to do all this bridging thing yesterday, did what you told (but before I found this thread). Off course it didn't work, but I didn't understand why... now I have a real, true final answer (rare in Linux world sometimes).

thanks also to allnightarockin for the perfect title

Cheers
