Windows File Sharing w/ Wireless & Wired Network

I am trying to share folders across my network between a laptop on a wireless connection and a PC that is wired to the router. When I try to access the PC from the laptop in the same workgroup, I get the following message stating //PCName/ is not accessible. The same procedure works fine when the laptop is on the wired network instead of wireless. My setup is as follows:

Linksys WRT54G Router
Microsoft MN-720 Wireless Adapter
Windows XP Professional on all machines

Any help would be greatly appreciated. Thanks.

When the laptop is using a wireless connection, can it successfully obtain an IP address from the router (presuming that you are using dhcp)?

Yes...gets ip address and connects to internet fine. Seems to be an issue specific to windows file sharing.

What is the exact error when you try and access the laptop?

If the laptop is plugged in my workgroup shares are accesible, connecting via wireless to the WRT54g that the machines are plugged into no dice. The error given is 6118 "The list of servers is not currently available"
I've got to believe it's something with the WRT54g. But even with it's firewall turned off, just to be sure, still no luck. Would love to find someone who's solved this before digging into the network traffic to find out what it's dropping.

Can you ping between the three computers?

Perhaps something here may help:

Did you ever find a solution to this. I have similar setup - disabling the router's firewall fixes it for me, but I really don't find that an acceptable solution.

Do you have file and print shareing installed on the wireless adapter? sometimes this is overlooked and only installed on the wired nic.

I have the same problem.

Windows XP laptop and a windows xp desktop connected through the linksys wrt54g. When the laptop is plugged in to the LAN cable, the computers can see eachother and filesharing works. When the laptop is connected wirelessly, the computers do not see eachother.

I think it's a problem with the WRT54G b/c this exact setup worked fine at my old place using a D-link router.

I'm using the sveasoft firmware for the wrt54g. I tried looking through some of the advanced settings, thinking that may help but I have no idea what they do.

Please help!!!

I had the same problem with sharing files between 2 Computers. DSL PPPoE connection to WRT54G, Computer 1 Windows XP, hard wired to port 1 of WRT54G. Computer 2 Win98/SE with WPM54 G wireless adapter. After the default config of the WRT54G using the 192.168.1.1 connection via PPPoE I was able to access the internet on both but could not always see/share files. I used the "How to set a static IP address in Windows behind a Linksys Router" procedure from the Linksys Knowledge bases #534 and all seems fine now. The tech support from Linksys was bad and it seems like the default dhcp server is not recognized as well as the assigned IP addresses. Good Luck
