Wireless WPA2-Enterprise Connection Issue

Postby blin » Fri Dec 02, 2011 9:21 pm

Running Windows Home Server with Radius server installed and configured. Out of the four laptops using wireless one will not connect, all laptops are running Windows 7, two running running Ultimate and 2 with Home Premium. three will connect with out any issues, one will not, its one of my Ultimate machines. It has successfully connected once but I was "experimenting" with some of the settings and now it will not connect. I have reset all the settings to be identical to the other three but still no go. I have deleted and recreated the connection, again duplicating the same settings still no go.

My connection settings are as follows;

WPA2-Enterprise and TKIP is selected. For the Authentication method selected Microsoft Protected EAP (PEAP) De-selected Validate Server certificate

Selected Configure and De-selected Automatically use my logon name and password.

Under Advanced Settings, tab "802.1x settings" I have "Specify authentication Mode: User or computer authentication". Next section selected "Enable single sign on for this network". The radio button "Preform immediately before user logon" is ticked. Also have selected Allow additional dialogs to be displayed during single sign on. Under tab 802.11 settings under Fast roaming, "Enable Pairwise Master Key (PMK) caching checked. PMK time to live (minutes) = 720 and "Number of entries in PMK cache: = 128.

Again these are same settings as the other three machines.

An update I hooked up an external USB wireless device and can log onto my wireless connection, I can take my laptop out of my house and get a connection. It is specific to this one access point .... could this be a registry issue? If so anybody know where the settings for wireless devices are located in the registry? Is this even possible?

First, please check this issue in Clean Boot.



If the issue persists, please go to run the built-in network troubleshooter and delete and recreate the wireless network connection.



Also, please take the following steps to test this issue:



Configure the connection to obtain an IP address automatically
=======================================
a. Click "Start", input "NCPA.CPL" (without quotation marks) to Start Search bar and press "Enter".

b. Right-click the network connection and click "Properties".



If you are prompted for an administrator password or confirmation, type the password or provide confirmation.



c. Click to highlight "Internet Protocol Version 6 (TCP/IPv6)" and click "Properties".

d. Check "Obtain an IP address automatically" and "Obtain DNS server address automatically".

e. Click "OK".

f. Click to highlight "Internet Protocol Version 4 (TCP/IPv4)" and click "Properties".

g. Check "Obtain an IP address automatically" and "Obtain DNS server address automatically".

h. Click "OK".

i. Reboot the computer.



After that, please try to uninstall and reinstall the latest driver to test it.

Tried all suggestions, previously I have deleted and recreated the wireless connection and have uninstalled the built in wireless connection all to no avail.

Verified both IPv4 and IPv6 settings are automatic, they are.

As stated previously the built in wireless adapter works in other locations but not "in house".

Not sure what happened but the built in wireless connection has started working, at first it was spotty, some times it would log in and work other times I would have to hook up my USB adapter. This evening I have gone through several reboots for various reasons and each time I have gotten a connection. Wish I know why so if anybody else had this problem could give them a possible solution.

Right now the solution is to use an external connection until it works it self out, crappy solution.
