I can't ping or access shares on a laptop when it's connected via wireless.

I'm trying to setup a scan-to-folder for an end user and every time he's connected to the wireless you can't ping his computer or access the share.  He has an Atheros wireless adapter and is connecting using the built in Windows 7 wireless client.  It had been working and the only changes I made sure upgrade to Windows Pro and join to the domain.  The only group policy's being applied are to disable the windows firewall, and give the user local admin rights.  I have removed my AV software, made sure firewalls are off, and upgraded the wireless driver but with no success...  It works when you plug it in with a cable, but there's no jack close to his desk.  Any ideas?

Ensure that  network discovery and file sharing are both ON.

Also make sure the wireless is on the same subnet.  I routinely make my wireless a different VLAN so I can control what kind of traffic is moving across it.  Though in all of my cases, the wifi is more for guest/visitor type internet connections, and will generally on have a route for Wifi to outside world.  In many cases, I even have whatever is serving DHCP give external DNS for these WiFi users too, and no traffic goes from LAN to WiFi intentionally.

Are you sure the firewall is disabled on the wireless and not just the wired connection?  If on the same subnet/VLAN it does sounds like a firewall issue.

@xBouchardx  Network discovery and file sharing are on

@tsaico  It is in the correct subnet... I can ping my workstation from the laptop having the problem, but I can't ping from the workstation back to the laptop.

@RobWill  I agree it does sound like a firewall issue, but when I type firewall in the run box, it says it's disabled and it's using the domain profile.  I don't have any VLAN's. I have the access point plugged into a new Firewall/ Router.... I wonder if it's blocking it somehow.  I will try plugging the AP into the switch and checking out the firewall.... I will have to wait until tomorrow to continue, they have taken their laptop home.

Is it an access point or a wireless router?  A wireless router will act as a firewall allowing outgoing connections but not incoming.  A true access point integrates with your primary router.  If it is a wireless router you will need to configure as per:

Can you ping anything at all when connected wirelessly?  Do you get a valid IP address and DNS?

Sorry I took so long to get back with everyone.  I was able to fix by updating the firmware of my access point.  Strange one I know, but that's what did it.
