Windows 7: Advanced Wireless Network Problem, WinXP Connects but Win7 Wont

Advanced Wireless Network Problem, WinXP Connects but Win7 Wont

Good morning everybody!

My D-Link rooter is driving me nuts! Basically I have many computers in my home and I seem to have an issue with encryption and compatibility.

I have..

My Works PC - Dell Dimension 1100 Windows XP Pro
My Works Laptop - Compaq Presario Windows XP Pro
My Rig - Windows 7 Ultimate 64bit
My Tablet PC - Windows 7 Ultimate 32bit
My Partners Laptop - Windows 7 Home Premium 32bit
My iPhone 4

My Rooter - D-Link DSL-2640R

With the default settings in the rooter (Mixed WPA, WPA2) My iPhone, Works PC and Works Laptop connects to the wireless network no problem, it appears they are using WPA mode whilst connected. However my Windows 7 machines are all seeing the network as WPA2. When I attempt to connect to the network it fails on all Windows 7 Machines.

I can only seem to connect the Windows 7 machines if I change from "Mixed WPA, WPA2" to "WPA2 Only" which then knocks out all the Windows XP machines

However if I disable wireless encryption, which I don't particularly want to do. All the machines work correctly with no problems!!!

I do have a function for "Guest Network" which broadcasts a 2nd separate SSID, but you cant use encryption on it. That could run the Windows 7 Machines but the problem is I don't know how secure it is.

Do you have this option, WPA-PSK (Wi-Fi Protected Access Pre-Shared Key)

If so use your own Key or Just retype the one that your using. Should be just as good as the others.

Change the Router to WPA2 only. Then on XP machine see if you can select the type of Wi fi connection to be WPA2. Also try both AES or TKIP.

Unfortunately no I don't have an option for WPA-PSK, I will try the next suggestion. My only worry is I know I have had problems with WPA2 on XP before. Will try and report back!
Thanks for the advice

After all that, I will say never trust D-Link products to work correctly. I have got a cheap replacement unit made by Huawei. Does everything I want it to, much faster and reliable.
