Intel(R) PRO/Wireless 3945ABG problems.
I have a Dell e1405 laptop (aka 640m I believe) with a Intel(R) PRO/Wireless 3945ABG adapter, running Windows Media Center Edition. I usually leave my laptop on and docked to a CRT and USB keyboard/mouse. It seems that after a few days (usually 4-5) my wireless connection dies. It starts out first as not being able to make any new connections, and then all active connections are dropped. If I deactivate the wireless connection or turn off the radio I am unable to reconnect to my wireless router until I reboot. The issue is not with my wireless router (Linksys WRT54G), as the other PCs are never disconnected. When the wifi on the laptop dies I am able to ping the laptop itself, but no other PCs on my network. Before my applications usually reported errors similar to this when the wifi dies:
"WARNING: error writing socket: No buffer space is available or a buffer deadlock has occurred. The socket cannot be created"
I have taken the following actions in attempts to remedy the problem:
Update the wireless driver.
Clean install of windows.
Increased the number of tcp/ip connections (http://web.ircsystems.net/codemastr/bufspace.html)
(not 100% sure that this actually did anything)
After doing the above mentioned steps I no longer see the buffer space errors, but the wireless still quits after a few days of uptime. I have checked the Event logs and the only significant thing that has popped up was a Event ID 4226 (Tcpip):
"TCP/IP has reached the security limit imposed on the number of concurrent TCP connect attempts."
I understand that this can be caused by many things (p2p traffic, worms, a lot of http traffic), but at the time that the event was recorded the only thing I had going were a few SSH sessions and Aol instant messanger. I've used tcpview (http://www.microsoft.com/technet/sysinternals/utilities/TcpView.mspx) to check my network connections, and there is nothing out of the ordinary when the wifi dies. (I've checked with netstat -an as well).
Anyone else experience anything like this or have any suggestions?
My setup:
Dell e1405 with Intel(R) PRO/Wireless 3945ABG.
WPA2-Personal (WPA2 PSK) using AES/CCMP encryption.
Intel Driver Version: 10.5.1.75 (hardware version 2.0.30)
Windows XP Media Center Edition (2005).
Linksys WRT54G (running DD-WRT v23 SP1 Final)
Windows Firewall is turned off. The only other related software is a cisco VPN client (though this issue has happened previous to the installation of the vpn client)

These are the two applications that I believe to have been causing the issue:
ZCfgSvc.exe
iFrmewrk.exe
