I have two PCs and a laptop on a wireless home network. Everybody was
sharing files just fine until I got a new router, now the PCs can still share
between themselves but the laptop can't access the PC files nor vice versa.
When I ping the laptop from itself or another computer it times out. No
security changes have been made to the laptop, software- or otherwise, only
the router changed. I can access the Internet just fine from the laptop. I
can "see" the laptop computer name from the PCs but can't share its files
even though they are set to be shared. Before I fry my brain any
further....help? Any ideas on why this happened? Should I try to uninstall
and reinstall my wireless adapter, or is there some way I can reset the ip
address, or is there something I need to tweak on my router perhaps? I am
hesitant to try any of this without checking with someone more
experienced...I know just enough to be dangerous!! Thank you so much....Sandy

If you can't ping laptop self, I would check the firewall first.

Well, that did it, thank you Robert!! (You're hardly surprised, right?!) I
had already shut off Windows Firewall but it took disabling Norton's as well.
Why would installing a new router make the firewall a problem, though, when
it wasn't before? Is it okay to leave this turned off, or should I only do
so when I want to access other files or printers? I'm just trying to learn
something here, but if it's too complicated, no problem...
