    Intel Dual Band Wireless-AC 7260 constantly drops connection

    felyyy

      Hey guys,

      first of all, thank you for reading my post. I got a massive problem with my Intel AC 7260 Wireless Adapter in my Alienware Area 51 R2.

      For some reason, after nearly 3 years of constant performance and no hardware problems at all, the WiFi card of my Area 51 keeps losing Internet Connection.

      The strange part is, that the connection to my router is still intact, but the Internet access gets crossed out. I also have a notebook, an iMac and an iPhone connected in the same network and every device works just fine.

      To proof furthermore that my router works just fine, I tested LAN connection on the Area 51 and there are no connections drops at all.

      Back to WiFi Connection: I searched in some forums and there are some people who seem to have the same problem like me. For example: Alienware Forum - Killer wifi keeps losing internet connection

      What I already tried was:

      • installed latest driver from KillerNetworking (v.1.6.2149) x64
      • installed latest driver from Intel 20.70.0.4 for AC 7260
      • deactivated and activated Wifi Card in device manager
      • deactivated IPv6 (altough it worked 3 years with IPv6 settings on)
      • Power Management -> disabled "Allow computer to turn off this device to save power"

       

      To make it as understandable as possible, I'll try to list the scheme of the problem:

      1. WiFi Connection is "stable"

      2. Suddenly the current application stucks because the PC has no connection to the Internet. After 10 secs, the WiFi symbol gets crossed out. Windows displays that I'm still connected to the router, but there is no Internet connection. (every other device is still connected and has internet connection though)

      3. For 1 sec, the crossed out WiFi symbol changes to a crossed out Ethernet connection Symbol (like I had a LAN cable connected, with connection to the router, but not Internet connection)

      4. And 5 secs later, the WiFi symbol pops up again and the Internet connection is back again.

      5. Repeat multiple times a day

       

      I can confirm that the connection drops are not coming more frequently when the download/upload-traffic is high. The connection drops in an idle state on the desktop of Windows as well.

      Do you have any ideas? Do you think it's a hardware defect?

      Keep up the good work!

      Best regards from Germany,

      Felix
