My Laptop don´t detect wifi networks.

Hi everyone!

I have a laptop that does not detect wifi networks. One day I was surfing the internet and suddenly I close the browser and the internet since I have not find any wifi network. Sanitize your hard drive, I had trojans and viruses. I have checked to uninstall and reinstall and still the same. I have checked if the wifi connector manual for this power in the device manager is the driver of the wifi enabled. Not that is wrong with my laptop

I need help please ... many thanks!

Try system restore and take back your windows setting to an earlier date when it worked fine.
start-> Programs -> Accessories ->System Tools-> System restore.

What kind of laptop do you have?
on some laptops there is a switch to disable the wireless nic - ensure its turned on

I think this is your problem, because people ask me this question all the time.

On my home HP laptop,...the WIFI button above the keyboard turns the power to the wifi on and off (glows Orange when off, glows Blue when on).  If you look at the top of your keyboard....  there may be a button in that area.  OR, on some laptops there is a button assigned to the F" keys.    For example my Dell laptop, I have to do keypress Fn + F2 (Function key plus F2 key.)  Still on other laptops the are switches instead of buttons... like my Toshiba laptop that has a sliding switch to turn wifi on and off.

Hope that helps.
hello everyone, thanks for your contributions, but none of them serves
the wifi is on (a message) but no network, I have reinstalled the driver but nothing.

As you can reinstall the wifi network?

Thank you
At this point I would verify the setting on the wireless router, check the encryption method and reset key.  Go into the properties of the wireless adapter, and remove/re-add the wireless network you want to connect to using the new key.  Set it to automatically connect.

Also, you might want to check if there is an HP wireless utility that is running down there in the taskbar..... maybe try disabling it, reinstalling it, or try using windows to manage the wireless connection instead.
I've several SSID but the laptop dosen't detect nothing but other laptops detect correcltly all the APs.
It's run Vista and i use the windows interface to detect the WIFIs.
thanks

Ok, here is a quick and dirty trick to see if the radio is *really* on

Select your wireless card and hit start scanning.

If you get an error, the card is NOT on.  If you don't get an error, you SHOULD see wireless systems in your area.
