Weird Wireless Woes on an F560EM vista laptop

I've been tasked with repairing a friends laptop which came in with the symptom of not being able to connect to their wireless network.

Turns out the broadcom adapter seems to not be present in the device manager. Deleted and re-install drivers, no joy. Tried different driver version, partial success...

The strange thing is that it did come good on one reboot. Connected to my wireless fine. After a time, the laptop slipped into sleep mode and when i woke it up it had no wireless connectivity again. No wlan in device manager.

No difference in safe mode. I tried re-seating the adapter with no success.

Anyone come across anything like this before?

 

What brand laptop is this?

 

It's a HP/Compaq Presario F560EM laptop. Part of the F500 budget range of laptop.

 

Sounds like a dead card. Its hard to tell

but I suggest you update your BIOS to the latest one through the HP drivers support page. Some bios's have fixes for problems similar to these

Anyway a replacement wireless card shouldnt cost too much.

 

Thanks for the suggestions. I've updated the bios, windows and the HP software with no luck. Think it could indeed be a hardware error. Back to the vendor I think.

 

for those of yous who have not yet sorted out this wireless device problem..
i also had the same bother with my presario f560em. this may sound stupid but this works for me and my wireless comes on no bother now..
all i do now is hold the power button in 4 3 seconds when powering on and that fixed my problem. hope this helps you guys out there.
