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

    On Windows 7 Pro SP1, HP Pavilion dv6 (new laptop this week).  Sorry this is so long...but it's worth it!  I thought I should share my solution as this has been a major issue for many of you...last good deed for the year : )

    Just like everyone here on this forum...I've discovered these issues too... "Limited Connection", "No internet access", no Internet IP, etc. on several make/model laptops with their wireless connections.  When I got my new HP laptop, wireless worked fine at home.  Then I took my laptop to work and use the wireless...no problem.  After 3 days not connecting to my home wireless, I tried connecting yesterday..."No internet access".  I worked on it for at least a couple of hours.  There is talk about McAfee causing it (installed on the 2nd day)...which I mess with...I don't think it was the problem.  I tried the Microsoft reset TCP/IP fix, Fixit50199 (did not work for me initially).  I thought about the old fashion fix for Windows XP (which save me a lot of work with connection issues on PCs on many occasions), go in the registry and remove the winsock and winsock2 and reinstall the TCP/IP stack.  I recalled doing it for my brother earlier in the year on his Win7 and it worked for a while until he tried to connect at school.  He said it depend on which building he was at.  His thought is the router type...seems to be an issue with connecting to N routers on campus.  I thought about the last time I connected at home and how the automatic update kicked in just before the shutdown...more likely something in the updates/hotfixes corrupting the winsock profile for that wireless network connection that is already registered (is my guess).  Anyway long story short...here is how I fixed the issue...

    (Note:  if you read on other ways to repair the TCP/IP stack, don't try them...they don't work in my opinion...and I fix computer for a living : ).  I personally modify this for Windows 7...here you go...

    First, remove the wireless network profile that you are having problems with.  Search and open "Manage wireless networks" (without quotes), highlight the connection you are having problems with, and click "Remove".

    Second, backup the registry before you start if you like (http://windows.microsoft.com/en-US/windows-vista/Back-up-the-registry) and follow the below...be very careful and make sure you delete the right keys.

    How to uninstall and reinstall TCP/IP stack in Windows (corrupted Winsock2)

    To resolve this issue, delete the corrupted registry keys, and then reinstall of the TCP/IP protocol.

    Step 1: Delete the corrupted registry keys

    1. Click Start
    2. In the Search box, type regedit, and then hit Enter.  Click Yes to allow.
    3. In Registry Editor, locate the following keys, right-click each key, and then click Delete:

    HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Winsock

    HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Winsock2

    1. When you are prompted to confirm the deletion, click Yes.  Close the Registry Editor.

    5.  Restart the computer.

    NOTE: Restart the computer after you delete the Winsock keys. Doing so causes the Windows operating system to create new shell entries for those two keys. ****If you do not restart the computer after you delete the Winsock keys, the next step does not work correctly. ****

    Step 2: Install TCP/IP

    1. Click Start > Search box type "Network and Sharing Center" (without quotes), click on "Change adapter settings" on the right, double click on "Wireless Network Connection", click on the Properties button on the bottom left.

    1. Click Install.
    2. Click Protocol, and then click Add.
    3. Click Have Disk.
    4. Type C:\Windows\inf, and then click OK.
    5. On the list of available protocols, click Internet Protocol Version 4 (TCP/IPv4), and then click OK.  Do the same to reinstall IP Version 6, start with #2 above.  Click OK's & Close until you are out of the windows.
    6. Restart the computer.

    STEP 3:  Install the Microsoft reset TCP/IP fix from this site, Fixit50199, http://support.microsoft.com/kb/299357.  Just click on the button and Run it.

    STEP 4:  Now, setup your wireless connection again.  Wait about a minute for the "Internet access" to show up.  You should be good now...test by surfing the internet.

    If it still do not work, try the above again.  You probably did not do a step correctly (make sure to restart the computer).  Let me know how this works for you.  Happy New Year!

    I see that this issue has been around for a while, but I thought I'd add a post describing a variation on this theme. I have a Lenovo Thinkpad T410 running Windows 7 pro 64-bit. I've had the computer for a year and until about a month ago my wireless connection worked fine. Now, for no apparent reason, I find that whenever it goes to sleep, it won't connect to my wireless router automatically when I wake it up, and frequently it turns off the wireless adapter entirely requiring me to troubleshoot the problem and tell it to turn the wireless adapter back on when it discovers that it's turned off. I've tried several of the suggested fixes (uninstalling and reinstalling the network adapters, updating the drivers, etc., but nothing seems to help. Is this the result of a Windows 7 upgrade that I may have installed without reading the fine print? It's REALLY frustrating.

    Peter --- One month now and no fix from Microsoft, this says something about their interest in solving customer problems!!!!!!!!!!
