Hi --

 

One of those problems I'm ready to pluck my eyes out of their sockets it's driving me insane  :crazy:

 

Setup:
 
  • Airport Extreme 802.11ac Gen. 6 running latest firmware 7.7.2 -- Acting as WiFi Base Station - http://www.apple.com/airport-extreme/ 
  • Dell Vostro 1520 laptop with built-in Intel WiFi Link 5100 AGN WiFi adapter.  Current driver: The one suggested by Dell according to this laptop's Service Tag (version 13.0.0.107 from 09/15/2009)
 
Issue:
 
It started a few weeks ago.  One day, my laptop started to randomly disconnect from the WiFi in the house. Right now, if I try to connect, I get the message "Windows was unable to connect to NameOfTheSSID"
 
I can't remember if it started following an OS update. 
 
Facts that drive me crazy:
 
  • Of course I have tried with the latest drivers (version 16.7.0)
  • Of course I have restarted the router several times
  • Of course I have tried to go back to that router's previous firmware (7.7.1)
  • I have then gone back to the dell-recommended drivers when that didn't work out (but I have kept the new ones handy in case someone asks me to change-up again)
  • This laptop connects well elsewhere on other WiFi access points (!!!)
  • Other devices in the house connect well to the Airport Extreme, including all Apple products, but also a Win7-64bit workstation with a Atheros DW1525 PCI WiFi adapter (!!!)
  • Another Wintel laptop (legacy XP) with a built-in Intel adapter is experiencing similar problems.

So it's like, they work, but not together   :(

 

I am including a screenshot of my WiFi adapter's driver properties.

 

I am currently connected using an Ethernet cable // Realtek gigabit // plugged into the same router -- That works fine.)

 

Thank you in advance for trying to help me figure out *why* the WiFi doesn't work.

 

P.

Update --
 
As you can tell from the attached screenshot of Xirrus Wi-Fi Inspector, the built-in WiFi antenna sees the signal quite perfectly.

Update:

 

I was unable to connect to any another site today (see attached pictures).

 

So I guess it's not just because of the Apple device...

Have you tried temporarily turning off any WiFi encryption you might have setup (i.e. WPA, WPA2 or even WEP) and seeing if that changes anything?
