I have upgraded my PC from XP Pro (Intel Motherboard) to Windows 7 64-bit with an ASUS P8P67 Motherboard. CPU is Intel i7-2600 3.4GHz.
Everything else appears to be working fine except for the fact that I cannot connect with my Linksys E4200 wireless router. This connection worked fine when I was running Xp Pro and the Intel motherboard. I have up-versioned the WMP600N driver to 22.214.171.124.
WHen I run the Linksys Wireless Manager both the 2.4GHz and 5GHz netwroks are visible with very good/good signal strength. I have tried using a passcode (which worked fine under XP Pro) and using the adapter generated PIN. Neither one results in a connection.
The E4200 is operating behind a Motorola cable modem and my ISP is Comcast (this arrangement has not changed) .
I am about at my wits end because I don't see where I have done anyhing wrong in the setup.
In reviewing the forum postings there seems to be something about either Windows 7 (64-bit?) and or ASUS motherboards that is keeping things from connecting. It's almost like the E4200 thinks it has seen the MAC address of the WMP600N and is denying a connection because it thinks it is a duplicate. (Or maybe the other way around.)

Try to uninstall the existing drivers for the adapter and download the latest drivers from the Linksys/Cisco website homesupport.cisco.com or can be downloaded from the link - http://homesupport.cisco.com/en-us/support/adapter
# Click on Start --> Run and in the run box type "devmgmt.msc" and click Ok...
# Device manager window will appear and in that check for the Linksys adapter.. Right-click on the name of the Adapter that you want to install and click Update Driver Software…
# A window will appear asking “How do you want to search for the driver software?".. Click “Browse my computer for driver software"..
# Select the option “Search for driver software in this location “then click on Browse..
# Select the driver that you Downloaded and click on next button...
Then try to connect the wireless network that you have created. Here is the link for connecting the wireless network connection: http://www6.nohold.net/Cisco2/ukp.aspx?vw=1&docid=

Thank you for your help.
Followed your instructions and still was unable to connect. The adapter in the PC can see available wireless networks and both the 2.4GHz and 5GHz networks configured on the E4200 (422netSecure2 & 422netSecure5). When I right-click and then clink Connect I get the Connect to a network dialog to enter my Security K. After entering the Key there is activity on the Connecting to.... "processing" indicator and then the "Windows was unable to connect..." message appears.
I have other systems that are connected to the E4200 without any problem and this same adapter (WMP600N) worked fine when it was in the XP Pro system.

Now try to make some changes on the router settings as well:
A] With the help of Cisco Connect Software (if at all you have installed the router with the help of this software)
1] Open the software and go to the option which says "Router Settings"
2] Then click on the option which says "Advanced Settings" which will take you to the router's configuration page.
3] Then go to the Wireless tab, keep network mode as mixed,
For Channel Settings of 2.4 GHz you can make Channel Width to 20 MHz only and Channel to 6, 9, 11..
For Channel Settings of 5 GHz you can make Channel Width to 20 MHz only and Channel to 40 or 161...
B] If you haven't installed Cisco Connect then you can log on to the router's user interface using it's default IP address in the browser which is 192.168.1.1 and type in 'admin' as the password leaving the username field blank. This will take you to the router's web interface and then follow steps as mentioned above to make the changes.

Router settings are already at 20 MHz only for both 5 and 2.4GHz.
I have tried a number of channel settings. Currently they are set to 149 and 11.
Still no connection.
Please keep in mind that this link was working when the PC was running Windows XP Pro, an Intel Motherboard (32-bit) and hte PC/Router locations haven't changed. The signal level at the PC is 5 bars on 2.4GHz and 4 bars on 5GHz.
There is something going on here besides the router settings.
