Wireless & wireless button not working Pavilion dm4

[Locokid67]

Hi there

HP Support Assistant ran a BIOS update this morning and ever since I installed the update the wifi capability of my Pavilion dm4 3002sa (running Windows 8 fine since November 2012) has been compromised.

Basically, the wifi button stopped working and windows can't find any wireless device built in!?

I have updated all relevant drivers including the supposed HP 'fix' for the F12 button but now the F12 wifi button toggles Airplane Mode on and off only.  I can't turn the wirless device on through PC Settings as the little toggle icon there is greyed out so won't allow me to do anything with it. I have gone into BIOS settings and set them all to default but still the same issue.

Can anyone advise on a solution - I am due to travel for work on Monday so it would be great to get this fixed otherwise i take I will be taking a laptop away alongside an ethernet cable!! Is this simply a bad driver issue that HP will sort quickly?

Hello! Just had the same problem and I seem to have found a solution. I turned off the laptop, removed the battery and unplugged the power. I then pressed the power button for 30 seconds and the put the battery back in and plugged in the power.

Thanks for the suggestion but I tried that and it doesn't work for me unfortunately! Anyone else? Or should I go direct to HP for an answer? Thanks.

HP sent out a hotkeys driver update yesterday which probably addresses the issue.

That is great news ItsmeKT!  We're just waiting to hear back from Locokid67 to see if it helps resolve his issue.

I can't test this until next week as I'm away for work and had to leave said laptop at home cos the wireless didn't work 😉 but I'm keeping fingers crossed the update works. Sure someone else will get this before me.

Awesome!  Thanks for the update, Locokid!

Where can I get the hot fix.  I've been struggling with thie problem since I did a fimrware upgrde.  Did a firmware downgrade and that did not fix the problem.
