connecting to 2 different LAN's at the same time

[Bob A Job]

Heres the deal.
Ive been on a wireless internet connection through a wifi PCI card onto a Access Point which hosts our LAN (3 other peoples PC's) before being forwarded on to a net connection.
Im upgrading to my own ADSL but want to keep connected to the wireless LAN to continue gaming/chatting on that network,
I have 2 PCs currently connected to the wireless connection (through ethernet & 1 shared internet connection on the PC with the wifi PCI card)

So if i get ADSL and have both my PC's connecting through the new telephone adsl line, can i still have the second using my own net, but accessing the wireless network through the other PC.
In other words, can a PC connect to the net on one LAN and connect for chat & Filesharing on the other LAN without major problems?

Sorry if its confusing, it is to me too

you think that's confusing http://en.wikipedia.org/wiki/Network_bridge

the simple answer is yes ..... sort of - by setting up a bridge (which does exactly what it says)
your problem could start with two PCs though

XP/Vista both have the ability to bridge
your networks must be using different ip ranges
first connect both networks (you must have two network adapters)
also ... in real terms running two wireless networks in close proximity isn't a good idea ... so your new lan could do with being a wired setup!!

in network places .... select both adapters .... right click ... select bridge .....

this config is meant to be used by a single PC (server) ... I'm not certain what the outcome would be bridging two seperate machines (you should really buy a hardware bridge)

the alternative is to use the same workgroup name for both LANs ... and physically move the connections.
