Windows 7 cannot connect to WPA2 secured wireless network

Hi all,

I am facing problems connecting to my company's network with Windows 7 x86 Enterprise edt.

The wireless network is WPA2 secured with TKIP and it normally prompts for my credentials when I was on Windows XP.

I have tried with several other machines with Windows 7 x64, also Enterprise edt and that prompts me for my credentials before I connect to the wireless network.

It seems that the problem is with the Windows 7 x86 as I am not the only person with this problem.

Could someone please advice what I can do to resolve this issue?

Thank you and Regards

I've solved the problem by following procedure:

My router configuration

Authentification mode: Shared key

WEP Encryption: WEP-64bits

Key index 1

Initially W7 won't connect to the wireless network.

My steps

I have Czech version of Windows 7, so, please note that text in English version might be slightly different from my translations.

  1. Goto network and sharing center
  2. Select Setup new connection or network
  3. Select Manually connect to wireless network
  4. Type network name, select WEp security and enter key, finally click Next
  5. Click Change connection settings
  6. Goto protection tab
  7. Select Security kind: Shared and Encryption kind: WEP
  8. Retype network key
  9. Precc OK and Close

This worked for me.

In case you already have some setup for your SSID, delete id before.

    Your administrator has to change WPA2 to TKIP as he has an unsupported setup; there is a bug in the administrative setup as well because WPA2 and TKIP are incompatible.

    Further there are bugs in Windows 7 WPA2 handling code which was introduced in recent updates so you will have problems connecting anyway with many devices in particular the iPhone. IOS 5 has introduced its own set of bugs. I have IOS 5.1 and it has a range of problems.

    Typically it takes Microsoft & Apple about 6-7 months to correct the bugs so expect around another 3 months or so to go but sometimes they are quick depending on their assessment of the urgency - if a lot of people complain and the solution is not daunting then it is quick but they still have to go through Q/A; sometimes Microsoft sets up an interim fix which is available by navigating the knowledge base (you have to check some disclaimers) and be prepared to rollback the updated software.

    The quickest way to fix this is to hire a smart kid from MIT or even a high school who has an in-depth knowledge of networking and security protocols (very easy to find someone) and they can typically fix this problem within an hour - this is actually very cost effective and is unimaginably less expensive then anything else I have undertaken. Your company or administrator has to understand this.

    I justs spent a good hour with similar issues listed above. I have a new W7 laptop that wouldn't connect to my home wireless network. It could connect to other networks at other locations and could even connect to my iphone which is connected to my home network. It was driving me nuts. I tried everything.

    I could get it online if I hardwired it via cat 5 to my router but then the wireless would still not work. The last thing I tried, (which worked), was hooking it up via cat 5 to the router, removing all the previous wireless connections and recreating the new home wireless connection. Once I pulled the cat 5 out, it was still working. Rebooted and it still works. I'm stoked. AM now off to get drunk and celebrate.

    Good luck.

    I have the same problem, and when I put in enable 802.1x and then try to put the connection at WPA-PSK it takes off the enable 802.1x feature. I am lost.
