x220 Laptop - Wireless Jumping access points. (Strong signal to weak and back = Poor performance)

Windows XPTablet PC Edition 2005 V 2002, SP3

i7-2620M CPU @ 2.7Ghz, 4Gb Ram

 

Intel WiFi Link 1000 BGN driver 14.3.0.6 - 2011/10/27

AccConn:  5.84

 

T series Lenovo's do not have this issue.

 

Using the Wireless Connection Status window I see the Associated MAC Address jumping to another address which has weaker signal and then back to the original which is strong.  During such an event Outlook 2007 loose server connection, users complain etc etc.

 

This happens intermittantly and again definately on more than one x220 machine.

Check in Device Manager, under the wifi adapter. In the Advanced tab, there's a Roaming Aggressiveness entry. Change this to lowest.

If that doesn't work, try this newer driver (15.0.0.75):
