Elitebook 8440p wifi stopped working after windows 10 upgrade

HP Recommended
Elitebook 8440p
Microsoft Windows 10 (64-bit)

Hi, I am looking for help.

 

I have a HP Elitebook 8440p that I recently upgraded to windows 10.  I also did a bios update from F50 to F60. All hardware drivers are found and installed. There are no errors in the hardware management window and everything is peachy.

 

Today however, I discovered that my wifi isn't working. 
The wifi button seems to work, the little light goes from orange to blue and then my blue-tooth is working fine (I connected with my phone in a jiffy). 

 

If I go to my network center and click the adapters, the wifi tile has a red cross and is not connected. When I click to connect, it sends me to the windows 10 network GUI with the wifi button. I tried to turn it on but it will not. It stubbornly refuses to turn on.

 

The adapter in question is a Intel® Centrino® Ultimate-N 6300 AGN, I uninstalled it, en grabbed the latest driver from the Intel support site. But nothing changed. I tried to bridge the network adapter, and I tried to let windows10 do a troubleshooting run, and windows keeps insisting I should "turn on the wifi button" on the laptop, but it's already turned on, and blue, and the blue-tooth works.

 

Since the laptop says all drivers are fine, and the wifi led on the keyboard works as advertised, I am kinda stumped why it refuses to work. Do I need some kind of driver for the wifi button?

 

Any advice is welcome, thanks for your time.

 

Transjuicer.

Hi:

 

Try tweaking some of the advanced settings.

 

Some Intel cards are acting very strangely on W10.

 

Enable WMM for starters, and set the Roaming Aggressiveness to Lowest.

 

Here is a list of advanced settings for most Intel wlan cards.

Thanks Paul,

 

I changed the WMM settings and tried changing some other settings on a try-by-try basis, none of the changes had any effect.

 

I am sure that the wifi was working normally under windows 7 so I'm pretty convinced it's a windows 10 snafu.

You're very welcome.

 

Sorry that changing the settings didn't work.

 

The only other suggestion I can offer would be to uninstall the drivers you tried and use the latest W7 Intel driver from your notebook's support page, or Intel, and see what happens.

 

It is definitely an issue with W10. 

 

I had an issue with my Elitebook 6930p (the model before yours came out) with the Intel 5300 wlan card and was able to get it to work by using the latest W7 driver directly from Intel, plus finagling with those settings I mentioned.

 

After I upgraded to W10 the drivers showed working, but the device would just hang on the connection script and would not connect.

 

It has worked fine ever since I made those adjustments.
