Really hope someone can help me on this one.
Okay, i'll start with listing some facts so that you guys have got something to work with.
I connect to Internet through BT Broadband.
I have bought a NETGEAR DG834G Wireless Router.
I have also bought 2 NETGEAR Wireless WG511 adapters.
I own an iMAC and 2 Windows XP Laptops.
Okay, before I begin, please excuse my pathetic attempt at techy type talk - I really am a newbie of newbies and my terminology is way off track. In other word, I don't know my mouse from my keyboard.
Right. The router is connected to the iMAC via the Ethernet cable(?!).
Internet connects to that no problem.

Laptop 1 is connected to the router via the wireless card.
No problems there.
Laptop 2 is also connected to the router via wireless card.
Again, works like a dream for the internet.
Both Laptops have 100% signal strength and all is good.
Okay, I want to now create a network.
I try a few things, go through Windows XP wizards and so on and I find it difficult to get one connected. I put this down to the fact that there is a MAC involved so they are different platforms and thus cannot be linked unless another piece of softwear is purchased. I can't really affor dthat so I forget that idea.
Okay. So now I try and ping Laptop2 from Laptop1. NO, IT DOESN'T WORK !! Same the other way around.
Okay, so I take out the Ethernet cable(?) from the iMAC and plug it into Laptop1, which then becomes the primary source to the router. I now try pinging Laptop2 and it works. Well it didn't just 'work' straight away, I had to go through the Home Network Wizard that is located in the Network Connections folder on XP.
Okay, when I have the Wireless card in Laptop1 and NOT the cable, the icon for LAN (Realtek) says "network cable unplugged", which i kinda guess makes sense realy doesn't it. I also have this other thing in Network Connections called 1394 Net Adapter which does what, I dunno. When I DO PLUG the Ethernet cable in, it does this thing which 'bridges' all those things which seems to make things work.
Don't get me wrong, I would keep plugging Laptop1 into the Ethernet cable to play network games and talk to Laptop2 but the problem is that everytime I then take out the cable so to use just the wireless, it messes around with my settings and I have problems getting on the net.
Now I have spoken to Netgear and they are very blase in saying that "the router must be faulty" but I totally disagre with that notion. I'm sure that everything is fine with the router and that they are just being lazy.
I've posted this problem on a few other boards and I get these replys that are quite technical in their answers. What I really need is for someone to explain to me as if I were a martian from Mars who doesn't know what a PC is...in fact, I pretty much am

I'm so sorry for rambling on here, but I really am tearing my hair out.
Any help would be greatly appreciated
Yours awaitingly.
