....sigh... So I'm at the end of my rope. I have recently switched my entire home network over to wireless. Previously to this, I had a hodge-podge of bad ideas connecting a bunch of systems. But it worked. Somehow :) Here is the dilemmia. I now cannot access any resources over LAN. ie, shared folders, printers, etc. via windows XP. If I boot up via Ubuntu, everything is available and works no problem. If I connect computers via a hub or crossover cable, everything works great. But... over wireless.. nothing. The computers are XP MCE and Pro, with occasionally a Home computer connecting. I try accessing via run //computername/ I've tried ensuring everything is on the same workgroup... It seems the XP computers are completely blind to each other. As a temporary measure, I've installed Hamachi on everything, which works... but less than ideal. I can't figure this out. Help?

what do you mean by wireless? Wireless router? Ad-hoc? What?

Sorry. Wireless via my Linksys router (DD-WRT)

can they all get to the internet? can you ping between them? software firewalls turned off? BTW this "//computername/ " is wrong command Correct command is \\computername\ or on a peer to peer network better \\ipaddress\

Right. Sorry. Touch of the flu and forgot to use \\ instead of // in the message. I knew that didn't look quite right. Pinging works between everything. Everything has total web access. The only thing that seems not to work is file sharing. Cannot find any settings in DD-WRT that seem off...

I would suspect it is software firewalls then preventing sharing access. Turn them all off and see what happens.

all off. No luck.
