Wireless not working on a Dell Studio 1558 running Windows 7 Home premium

seems i have the same issue.. running windows 7 wirless not detected but the lan's working fine.. downloded dirves throws up an error 

Ok, my issue was solved.. I have a dell studio 1558.. This might be complicated but i had to do these steps to make my wireless work. If your driver is not compatible then that's definitely not the right one for your system.. Assuming you have a laptop, remove the latop casing and look for you wlan card and there should  be a number on it.. type the number in google to find the right driver.. Or give me more specifications of your computer il try to find the right one for you?

as you said your device manger is fine, you have the right driver..Make Sure

to  check for any unknown device in your device manger again.

Solutions:

Check your network adaptor ..

should be 2 adaptors. Make sure the wireless adaptor is

enabled.. post me for steps .

I am having the same problem. I had to reset my computer and re-install OS and drivers from a disc and from the available drivers via dell website, but keep getting a "system not compatible" type error message when I try to download drivers relating to my wireless capability. I have something called "WiMax" that is up and running but that is not the same thing I had before (the ability to connect my PC to wireless connections on modem).

Hopefully someone finds a solution.

my OS is windows 10. but day before yesterday its working properly.

my wifi not working. its showing wifi device not connected also showing some error in device manager driver.
