[XBOX 360] Networking question - please help!

[Fazley]

I currently have the 360 wireless adaptor to connect to my ADSL router.
It works so-so most of the time but interferes very badly with my cordless phone and my TV Video sender.
Consequently a lot of the time when Mrs Fazley is on the phone/watching TV I can't use it because the wireless signal kills her own entertainment.
Now here's my idea: My 360 is sat next to my desktop PC (which has an unused LAN port) - the desktop PC is in turn connectly wirelessly to my router (this one doesn't cause interference)
Is it possible to use a crossover cable from the 360 into my PC to piggyback off the PC's wireless connection to my router? If so how do I set this up?
Hope this makes sense.

yup. you need to get a cable (cross over should do the trick) and then enable ics or internet connection sharing. You might need to open ports on your router.

Or buy a new phone and bin the TV sender. DECT phones operate on same frequency as 802.11b/g
My dect phone seems to be fine however so I guess its hit and miss.

Yep, crossover cable should do the trick.
My dect phone is fine with my wireless network too.
I don't have the official Xbox360 wifi adaptor though, using an Asus AP to plug to my 360

Ok I'm getting mad with this now!
Here's the deal:
I have a wireless ADSL router on 192.168.0.76, a PC with wireless adaptor on 192.168.0.77 and a NIC (IP can be whatever I want) plus an Xbox 360 which is connected to the NIC via a crossover cable.
Whenever I enable the NIC I lose my Internet connection on the wireless adaptor. When I re-enable it I get the net connection back.
It seems that when the NIC is enabled it stops the wireless adaptor from sending or receiving anything.
I have no windows firewall or anything fancy turned on, wireless router is a Netgear DG834GT.
Anyone please? I'm getting annoyed with it now!
