I have just changed from Vista Home to Windows 7 Professional on my laptop. The laptop will access the internet with a wired connection only. It now indicates there are no wireless networks to join even though my is one of 50 in the area. I asked Windows to diagnose the problem but it has no suggestions.

Thank you.

Thanks for the help!

I am now able to "see" the wireless connections but not connect when I click to access the connection.

Friends who visit with their PC's can access my home wireless after they login with the password if they are using Windows XP and/or Vista.

My Windows 7 is still an enigma!

Spent $99 and 1/2 day with Microsoft online tech support without a solution!!!!

Upgrade to Windows 7 has been a "bummer" --- may have to go back to XP or Vista if Microsoft does not provide an update fix.

Again, thanks for the assist!

SOLVED Just signed up to perhaps help the miriad of stressed people as I was. I had 5 computers connected to home network combination of Vista and XP - no network problems. Bought new laptop with Win 7. Connected fine to network.

Left laptop alone for week or so - didn't even turn it off and when I tried to start it up - no network connection possible! Could still "see" network but wireless just would continually try to connect without success. Attached a ethernet cable from router to laptop and it connects fine - just no wireless.

Messed around with aes, tkip, antivirus plus heaps of other suggestions. But the solution was to upgrade the firmware on my router. Downloaded it from tplink website and opened the routers setting webpage and uploaded the newest firmware.

There's no doubt it is a Win7 problem as the old firmware works fine with xp, vista but they don't tell you this when selling you win7 and you spend heaps of time trying to find these solutions. I didn't try system restore but this would've been my next step as the win7 did work for a couple of weeks before it went down, so it has to be some kind of update or something that conflicted with the router after previously working.

Hope this helps someone.

While what you have listed here are some good basic things to follow, I was already doing them.  I saw my problem show up when a patch was applied to my laptop.  Originally I saw that patch being offered by the ASUS laptop update utility.  I backed it out and the problem went away.  Later I installed some Microsoft patches and the problem came back.  Here is the issue I am seeing:

When I first bring up the system the WIFI is never turned on automatically, as it is supposed to be and as it used to do prior to the patch.  I have to select the icon in the system tray, which shows the WIFI as of to turn it on.  It does so for all for about 5 seconds, just long enough to attach to the network, and then it turns itself off again!  I then have to do this a second time and that one will work.

It also turns itself off when any device changes are made to the system, such as plugging in or removing a USB flash drive.

I sometimes see it turn itself off when my screensaver has been running for a while, but it has to have been for quite a while, say at least 20 minutes.

I have completely disabled it being powered off by Windows, so it shouldn't ever be turning this off unless I tell it to.

This system has Intel My WiFi Technology in it and I saw some post about updating Intel drivers from their site fixed a similar issue, but it turns out that was for a different Intel WIFI chipset than what I have.  I have verified I am on the latest version of their drivers.

This become quite intolerable when I am at class at ITT and need to be on the network using my WIFI connection.

I am open to any suggestions.  Right now it seems my only option is to backout the last set of patches from Microsoft, because I don't know just which one causes the problem, and ignore all other patches that are made available.  That is not a good solution, because it means I will be ignoring possible security and bug fixes that I actually do need.

Hello Everyone,

I wanted to thank you all for the active discussion in this thread, and I would like to jump in and see if I can help address the multiple issues that seem to be covered in here.   I would also like to take the opportunity to thank Barb Bowman (MVP) for their efforts in this thread to date 

For a full list of steps to try, see the Wired and Wireless Tutorial on this page:

After reading through the thread, there appears to be some confusion regarding Wireless Networking technologies and configurations using Windows 7 and I would like to spend some time to try and clear things up with some basic troubleshooting / best practices for Wireless Network related issues.

1.       First try and power off your modem, router and desktop/laptop. Then power on the modem, then the router, and then finally the desktop/laptop. Please do this in that order, allowing 60 seconds in between each device to enable the device to be fully booted and able to accept connections.

 

2.       Update the drivers for your wireless network adapter via Windows Update, or by using the website for either the company you bought your PC/Laptop from or the manufacturer of your networking device.

 

3.       Ensure that your router is set to broadcast it’s network name (SSID), ensure that you are connecting to the correct wireless network (SSID) and that you are using the correct WEP/WPA  passkey on both devices.

a.       Please use “Windows Connect Now” or “Wi-Fi Protected Setup” if available on your wireless router to ensure that the connection is setup correctly.

 

4.       If you are trying to use WPA or WPA2, please ensure that both your network adapter and wireless router support this protocol. If you are having issues detecting your wireless network when using WPA or WPA2, try configuring your router to use WEP instead and see if you can connect.

a.       Please note that the change between WEP/WPA/WPA2 will need to be made on both your computer and wireless router.

b.      If you are only able to connect using WEP, then your networking hardware may need a firmware upgrade. If you are not comfortable doing this yourself, please call your hardware/router manufacturer for help in doing this.

 

5.       If you are having a problem with your wireless connection after resuming from hibernate or sleep, or are having intermittent connectivity issues, try to adjust your Power Management profile to change your Wireless Adapter Settings to Maximum Performance.

a.       To do this click “Change Plan Settings” next to your Power Profile, and choose “Wireless Adapter Settings” and set it to Maximum Performance. You should do this with all of your power profiles. Additional guidance is available here: http://windows.microsoft.com/en-us/windows7/products/features/power-management

 

6.       Call the support line for your router manufacturer. It is likely that neither Windows nor the router are having problems, it is simply an issue of getting the configuration settings on both set up to work correctly together. The router manufacturer will be the best resource to know how to configure their device.  Most of the contact numbers are listed here: http://support.microsoft.com/gp/vendors/en-us

If anyone has any questions please let me know.

Thanks,

    not sure why you have not updated for 8 months. but unplug your router, then run

    system restore. then go into Windows Update settings and change the settings to

    notify you, but not download.

    Turn your router back on. Go to the IBM site and install whatever updates IBM

    has available for your laptop, ignoring WU until you have completed that

    process.

    THEN--

    When WU offers the list of updates, check for drivers for your NIC card and any

    other hardware devices and HIDE whatever driver that are offered. Perform a

    manual System Checkpoint before proceeding with any WU updates.

    Reading the posts, my issues seems to match this thread but with some variation. My experience is most similar to that by Frank L on 3/15/10. I am a novice user. System: Lenovo T500 Thinkpad, Intel 5100 AGN Wifi Win7 Home Premium 64 bit Built 12/2009, set up 12/31/09, Trend Micro AV & firewall. Network: Netgear WTG624, circa 2005, WEP (yes, I now know this is evil, but at the time we had a wireless card that did not support WPA), SSID appears to by default. Other units on Network: Dell Dimension Desktop and 2003 IVM Thinkpad, both running XP. There had been no maintenance on this router since 2006 or 2007. The new Thinkpad set up fine out of the box, ran updates and connected to the network without difficulty. I must have set windows update on “prompt” as my spouse (her computer) checked with me several weeks later asking “should I let it update”. Allowed changed to auto updates and allowed updates to run/install. Immediately after restart, the wireless failed to function. Did not detect any networks (several in our vicinity). Basic troubleshooting was unsuccessful. Following expression of several colorful metaphors, ran system restore to the pre-update checkpoint and wireless began functioning again and automatically connected. Auto updates returned to “prompt”. It was a very busy time and we blissfully went on our way. July 30 and I am backing up my spouses data prior to travel. I notice that the Thinkpad was being prompted for updates. Forgetting the prior experience, I downloaded & ran updates for Java and for Windows in that order. Following the Windows update, wireless failed to function. Wireless indicator light out on the laptop, no networks detected, Nothing discovered on auto troubleshooting, firewalls turned off/on, attempted a manual connection - all unsuccessful. Could connect to network via Ethernet. Ran system restore to undo Windows update. After restart, connected briefly (maybe 30-60 seconds) to the network when wireless cut off – no networks detected. Ran restore again to undo Java update….same thing. Ran system restore a third time to a system checkpoint and “all was fine again”….except that Win7 likely has not been updated since 12/09. I appreciate the guidance offered by Kevin and others in the prior posts. My issue seems closely associated with something in Windows Update. I understand that there may be other configuration/compatibility issues in the background, but do not want to make a set of changes that either cannot be undone or difficult to track. Do you have any information on any of the Win Update components that should not be installed/blocked or best steps for proceeding? Thank you in advance
