Windows 7: Windows 7 and WLAN with WPA-PSK Encryption

Windows 7 and WLAN with WPA-PSK Encryption

Hello Everybody!

I've got a problem with Windows 7 Ultimate RTM and wireless LAN on my Lenovo 3000 N200 Notebook with Intel 3945abg wireless chip....

I can't connect to wpa-psk encrypted networks although I installed the newest driver from intel and tried an older version, too. The network adapter is installed correct in the device manager...


If i use no encryption or WEP there is no problem, but i must use WPA-PSK...

The network settings on my notebook and on the accesspoint are 100% correct, and it worked fine with Windows Vista and the same hardware...

Please help me and sorry for my bad english...

More information would be helpful. Does your laptop actually support WPA? (I have a pair of HP iPaqs that supposedly support WPA - but i I enable it on my router they always fail to connect. I was forced to use only WEP.

Also, My sister has a laptop with Symantec Endpoint Security on it - and her machine refuses to connect to WPA on my D-Link, but she says (claims) that it it works on her LinkSys....

Yes, my notebook had support WPA encryption. I changed nothing on the router and with Windows Vista everything was alright. It's a Windows 7 issue.

//Edit.: I had tried it on 2 differnt routers, WEP is working, WPA not...

I also have this problem. I have a Fulitsu LifeBook 4215. It connected using wpa-psk under Vista. I recently upgraded the OS to Win 7. In trying to connect to the WLAN, I can't see wpa-psk as a protocol option. I've tried each of the wpa / wpa2 options without success.

What wifi card do you have in your laptop? Did you install Fujitsu drivers for it, or did you let Windows find and install the drivers? If you let Windows do it, you might want to install Fujitsu provided drivers - visit the support website and see if there are Windows 7 drivers for your wifi card. If there aren't any, use the Vista drivers and install in compatibility mode.

I just connected successfully. I'll talk through the steps, which are a bit bizarre, because there's nothing terribly much different that what I'd been doing before.

I had tried using WPA-personal TKIP and WPA2-personal TKIP, with the right password. No luck.

What I did this time:
* powered off and on the wireless router and modem (which shouldn't have affected things - other computers were successfully using them)
* on the connection properties dialog, checked the option to connect to the router even if it's not broadcasting its SSID (which it was, as I could see it in Win 7 - but I had not tried this before)
* selected WPA2-PERSONAL with TKIP
* checked the option to show characters (which should make no difference, and I had checked this before anyway)
* entered the password

And it connected immediately. The only things different were the reboot of the modem and router, and the checking of the option to connect to the router even if it was not broadcasting its SSID.

Go figure...if anyone can explain this I'ld be grateful.
