Intermittent Wireless Connection in Fedora Core 6

[Jeffrey D. Yuille]

Hello,

     I recently did a clean install to Fedora Core 6 on my IBM ThinkPad 
T-30 laptop.  I am using an Atheros-based wireless card with WPA-2 
encryption.  The madwifi drivers are installed and I have a Linksys 
WRT54G Wireless router.  I started NetworkManager, 
NetworkManagerDispatch, and wpa_supplicant in 
"system-administration-server settings-services".  I also unchecked 
"network".  Although I was able to connect wirelessly, the signal seems 
to be dropping every 10 seconds or so.  After a while, the signal will 
stop entirely.  Has anyone experienced this problem?  By the way, the 
wireless router is approximately 2 feet away from where my laptop is.  
Any help would be greatly appreciated.
