M4400: Intel WiFi Link 5300 AGN Failure

This has been happening a for a couple weeks now.

Problem:

Every time I boot up the computer and switch on the WiFi/Bluetooth button on the right side - only the Bluetooth light turns on above the keyboard.

Temporary Solution:

I go to Device Manager and find that the "Intel WiFi Link 5300 AGN" slot has the exclamation sign next to it so I disable the card and then reenable it again, then the problem is gone (the WiFi light turns on and I can now finally see wireless networks in the "Connect" window).

This is only temporary because once I restart the laptop, the problem is back and I have to do these steps over again.

Permanent Solution:

Does anyone have suggestions?

 

Try uninstalling the drivers and reinstalling them from dell's website. Sounds like a driver problem to me. Only other thing I can think of is that you some how disabled the switch from affecting the wifi connection. If the latter, then you'll need to go into the BIOS and check wifi for what the switch controls.

 

if you have the dell warranty, why dont you give them a call? easier to let them sort it out. they might even give you a new card or somethings

 

Try an update version of quickset that supports this card.
