Wireless connection stops working when I try to bridge it

[moody84]

In my house, downstairs, my dad's computer is connected to the net using a USB ADSL modem. I have a belkin wireless router connected to it, working as an access point. My computer is upstairs with a wireless network PCI card (running win XP home_. With my dad's computer (also running XP home) with internet connection sharing I can access the internet from my computer via his. This works fine although I would like to get an ethernet ADSL modem so I don't have to run my dad's computer for internet access.
I also have another computer in my room running ubuntu. I intend to connect the ubuntu machine to my win XP machine using ordinary cat5 and a switch. I then hope to give internet access to the ubuntu machine through my win XP machine. This should be possible by bridging the wired network card and the wireless network card on the XP machine. It would be a bit of a tortuous route:
[ubuntu machine] -> wired network -> [win XP machine(bridging connections)] -> wireless network -> belkin wireless router(working as access point) -> wired network -> [dad's XP machine(internet connection sharing)] -> USB ADSL modem

My problem is this:
when I select the wired and wireless network cards in my windows XP machine network connections and choose 'bridge connections' the wireless connection stops working. Does anyone have any experience of bridging wired and wireless connections in windows XP? I hope someone can tell me what's gone wrong and what I can do about it.
Thanks

That's a very hard way to do things. Every time you bridge a connection or add a routing device you add another layer of network address translation. Each layer has to be on a different subnet. XP's ICS is hardwired to 192.168.0.1 for the bridge host, and you cannot have this address on your network more than once.

I see my current plan won't work using ICS. I would like to simplify the whole thing and dramatically imporve the reliability by using cat5 throughout. Unfortunately that would involve drilling holes in the house which is not allowed. I don't see any other solutions that don't involve buying new equipment and I'm not in a position to do that at the moment due to being unemployed. When I get a job, I'll fix it. At least it gives me an incentive to get job-hunting
