X220 - Access Connections Wireless issue - Driver disconnected while associating

Question

I am trying to connect to our wireless network at work.  I have verified that my settings are correct with the other X220s that we have connecting to our network.  When the connections fails and I select "help me fix this" I get four error messages.
Thanks in advance if anybody has any ideas.
Connection status:  Not connected
Cause:  The driver disconnected while associating.
Error code:  229378
Recommended actions:
The selected wireless network is out of range or unavailable.  Move to a location that is closer to the access point and try again.
Verify that the encryption settings (WEP/TKIP/AES) specified in this profile match those expected by the wireless network.
Verify that the wireless adapter in your computer has not been restricted from accessing the radio channels being used by the wireless network.
Verify that the wireless network name (SSID) is specified correctly. The SSID is case sensitive.
If the problem persists, contact your network administrator and provide the troubleshooting information below.

Answer 1

I share your pain with same Intel WiFi Link 1000 bgn.  After many, many hours yesterday I am now solidly running Wireless N at 144 Mbps on a LinkSys E4200, 99% reception from 30 feet away.  
Previous to yesterday I could not get 'N' to work at all.
First, if you have a newer dual frequency Router, this Intel adapter only supports 2.4ghz..
1. I am using Access Connections 5.85, Windows 7
2. Router: 2.4 Ghz Network Mode: Mixed
3. On my LinkSys router Channel: Auto NEVER worked for either  'G' or 'N'.  I picked channel 4 by chance and things got better.  No further experiments. 
3. Channel Width: Auto (20mhz or 40mhz).
4. Earlier forums indicate WPA2-P and AES must be selected.  That's what I am running.
5. Numerous references to "power" conflicts.  Set all Power Management to Maximum Power. 
(Control Panel -> Device Manager ->Network Adapters -> Intel WiFi Link 1000 bgn -> Power Management)
(Access Connections -> Wireless Settings -> 4. Advanced Configuration-> Maximum Performance)
If you followed these steps, Wireless G should be working stabily for you now.
Now for the secret sauce to make Wireless N work:  go to http://communities.intel.com/message/82098#82098
See Feb 3, 2010 post How to get 5100 AGN to connect at N speed?
I am indebted to this guy.
Save the instructions!  For some reason my EDGE 14 wireless totally quit this week and that's what sent me down this wireless rabbit hole again.  At least this time I was able to make N mode work for the first time.
Frustrated but relieved,
