Noob networking advice

So I think I've figured out the ABC problem but I'm now stuck with accessing other pc's connected to my router. I could do it fine with 98SE but XP, I'm lost. I've set the PC's to share files but can't find them anywhere. Any ideas?

Or is this a VPN kinda thing?

 

This is the starting point for file sharing:

And just when I thought the d@mn thing was working ok then this happens

The wired connections seem ok but the wireless is useless. After finally been able to put it on another channel, it works then vanishes again. I can understand it might be interference but I've tried 3 different channels and my laptop is no more than 30cms away and it can't read it properly.

Search Netgears website and they keep mentioning "bridged mode" but I can't find info about it.

So any ideas please? Thanx

 

Phone

If your cell phone has bluetooth capabilities it could be connected to the network via one of the PCs which could be bluetooth capable either with a built in bluetooth in the case of a laptop or a usb bluetooth device on a PC
