The type of security that the adapter could use or not use is a property of that adapter. Some are not compatible with WPA.
Windows 7 and WLAN with WPA-PSK Encryption

haha youre absolutely right, however the thread is about those computers who have formerly connected successfully to their access point/router, but when the software only is changed to Windows 7 with no hardware changes made at all, the computer can no longer connect.
accordingly, there is no issue with the adapter connecting to the router as it used to do so under the old operating system. It is a problem with the OS or the Driver, and you can resolve the problem by enabling wider security support on the router side of the equation.

What software are you referring to?
How come i don't have any issues, with Xp or W7 using the same wireless network from my router?accordingly, there is no issue with the adapter connecting to the router as it used to do so under the old operating system.

by software is changed to Windows 7 i am referring to the operating system only eg. Installing WIndows 7 on a machine that used to run Windows XP.
the reason that you have no problem with your network device and router when you upgrade a machine from another operating system to Windows 7, is because of your particular network interface card, router and security setting combination - most users as is the case for you, will experience no problem in the upgrade.
some users however have a combination of network interface card, router and security settings that DO create a problem when upgrading to the new operating system, and they are the target of posting a suggested solution as above...Last edited by kyuss; 15 Jan 2010 at 06:22. Reason: grammar

Yes understood that. But i fail to see the requirements of lets say WPA to be different from going from XP to W7.
In XP, the router broadcasts the wireless network encrypted with WPA, wireless card is compatible with WPA, and XP is able to detect this network (SSID) and let you log on.
In W7, the router broadcasts the wireless network encrypted with WPA, wireless card is compatible with WPA, W7 will detect this network (SSID) and let you log on.
You got 2/3 variables which are unchanged and is independent of the OS. The third variable is the tool used on the OS, whether builtin or thirdparty (used by the adapter). If you used the builtin tool, then there is no reason why Xp works and W7 doesnt. If there is an issue with the driver of the adapter, then this needs to be addressed. Sameif you use thirdparty tool from the adapter. What the router broadcasts, it does so without descrimination between OS types.

i think what you are failing to take into account is that this worked. with no other changes to how my computer was trying to connect to the router - and failing, i allowed legacy support on the router, and windows 7 was suddenly able to connect, so all of our discussion and semantics aside I have provided a solution.
if you think this solution shouldnt have worked, you are incorrect. it did.
if you dont understand why the solution worked or dont believe that it should be necessary, you are wrong.
I came searching for a solution and found this forum thread because i had a problem - my network with no change in hardware, just a change in operating system, was no longer working.
i dont understand what point you are trying to make in saying this shouldnt make any change, this isnt blah problem etc, i created an account on this forum to share that I had resolved this problem as it manifested for our computer setup, and potentially have added value for other similarly affected users if they happened across the same thread.
perhaps if i can't express myself in a way that you fathom what i am writing about, and if you arent experiencing issues with your networking and windows 7 experience, you should move on to expending this time providing input on other forum threads which can probably use your knowledge to solve other issues

Ok so it has worked before. How many times? Did you know that your setup might not have been setup 100% correctly, and this could be the cause. I've seen and experienced settings that are NOT 100% and it works (only to die short after like your situation).
The thought that if it has worked, and assuming everything is 100% setup correctly, then have you made any changes to your system. Sorry if these questions have already been answered but i go through alot of thread and easily who said. Things do not simply worked and then not work.

cool,
no changes to system (hardware).
when i booted up after fresh install of windows 7 i tried to connect to the router i had always connected to from the laptop i had always used.
it asked for the security key which i entered and then stated "limited connectivity" and there was no internet available.
on clicking on the networking icon and mousing over the network i was connected to it stated it was using WEP security by default, like Windows 7 had picked up that the incorrect security was being used by the router (which had always used WPA2)
i right clicked on the network and selected properties, enabled the check box "connect even if the network is not broadcasting its name (SSID)", and changed security type to WPA2-Personal with TKIP and reentered my password
with these settings the windows 7 networking icon in the system tray indicated that i was unable to even try connecting to the network (indicated by a red cross next to the network name instead of the bars of reception)
i tried all combinations of security type and encryption type WPA2Personal/TKIP, WPA2-Personal/AES, WPA-Personal/TKIP, WPA-Personal/AES even tried to use WEP that I knew was incorrect.
all yielded the same red x next to the network name, and no ability to try connecting (connect was greyed out in the right-click menu)
went to the router and changed it to support legacy connections per my first post, and the connection started to work.
agreed, i have seen posts of people re-booting their router, modem, and re-booting their laptop/desktop and their network connection suddenly works but falls over again a couple of hours or days later.
so far so good for me. no dropouts, no failures to connect.

I think this is your adapter's setting, and you have tried changing it to match the router's security?on clicking on the networking icon and mousing over the network i was connected to it stated it was using WEP security by default
I'm not clear where you have changed the security, the wireless icon and the connections in connection manager are two seperate things.

The problem is caused by incompatible driver. Method to resolve as follows:
1. Right Click on Computer and Select properties
2. Select/Click Device Manager
3. Expand the Network Adapters
4. Right Click on the Wireless Adapter and select Update Driver Software…
5. Select/Click Browse my computer for driver software (Locate and install driver software manually.)
6. Select/Click Let me pick from a list of device drivers from my computer (This list will show installed driver software compatible with the device, and all diver software in the same category as the device)
7. Select/Click Have Disk
8. Browse for the compatible Driver (Either on your original driver CD, download from internet Downloads Folder, or your prefer location such as Desktop)
9. Select/Click/Open on the Driver and to install
After the successful l driver installation, connect the internet by using the wireless adapter. Occasionally, you may encounter the problem such as connected to network but without access to internet. Just go to Control Panel/Network and Sharing Center and Click on the “Red X” between the Network and Internet to auto rectify the connection problem.
Cheers! Hope this is helpful.
