SQL Application VERY slow, only over wireless not wired
I have a client with several locations that all connect to the central location via VPN Tunnel using either SonicWall or Cisco ASA5505. At the main location there are several virtual servers hosting their EMR application "eClinicalWorks". Any computer anywhere using a wired connection has no issues what-so-ever. EVERY location has a Cisco WAP 1142 and the only complaints are of slowness or the application hanging when used on the laptops connecting to the wireless. It seems that if they are wired it runs perfect. They are using WPA2/TKIP/AES.
Anyone have any ideas as to what might be causing this application to hang only over the wireless?
Thanks in advance, and I apologize if this is the wrong forum, please move accordingly.
