Recently got sky broadband and can now access the internet through both computers. However im not sure if this means i have set up a network ( dont think i have) as i can not file share. The hardware given is a wireless router from NETGEAR model DG834GT. The router is cabled into my main computer and my lap top is connected by wireless. Therefore i dont know if i need a wireless card in my main pc?  otherwise i dont know what im doing wrong do i need setup a wirless network or just the normal networking setting. The computer names (workgroup) have the same name. The only other thing i can think of is that i dont think my router has a software installed  as i dont think it came with sky or its because i didnt run through the sky cd properly as it trys to install Explorer 7 which checks if u got a valid windows which i havnt
Any ideas would be GREAT if possible

Cheers DaveI'm almost having the same problem.  I have a Linksys wireless 150n router and a linksys wireless n pci adapter.  The computer hooked to the router is running win 2000 with sp4 and the computer with the adapter is win xp pro with sp2.  Both connect to the internet just fine.

Now what I'm am getting from a few other people, is that if you are running firewalls, this can cause problems with sharing.  Win 2000 has CA security center running on it and win xp has norton 360 running on it.  I have GONE in to both to enable file sharing, and also in the network connections I made sure file and print sharing was turned on.  I also disabled the windows firewall that comes with xp.  Beyond that I don't know what to do. 

My win 2000 computer can SEE the other, but comes up with the error that it can't find the path.  The xp computer doesn't see the other.  I've also checked to see if the ip addresses are different and the subnet masks are the same.  They are.

I haven't yet tried just turning the firewalls off to see if it works.  I might try that tomorrow if all else fails.  Though I would like to have some protection you know.  Any help for us would be great, thanks.
Okay, so basically today I went ahead and turned off the firewalls to see if that helped.  Well, what do you know, it worked.  So, my bottom line is that if you are trying to get file and print sharing to work and you think you have everything right, and you have firewalls, it's probably the firewalls.  Now, yes it worked turning them off, but alas, I want to keep them on and still have it work.  I have fiddled with the settings for many a hour trying to get it to work with no success.  so, if you want  your firewalls on to don't ask me, i haven't figured it out, yet.  Of course the brand of firewall running will probably PLAY a bit of a roll on what the settings are that need to be configured too.You don't have to disable the firewall(s)...you just have to let your firewall(s) know that you want to allow network connections.

Check you firewall documentation for this.
