Intel Dual Band Wireless-AC 7260 constantly drops connection

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 red. 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 a 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

For me it works OK.

open a cmd prompt type

ipconfig /all

post results when its working and when its not

Hey guys,

thanks for your answers. Sadly my problem is still present.
I managed to take screenshots from the whole process as well as ipconfig /all in a state where the internet connection has dropped. Maybe this helps further.

Hey guys,

Thanks for your answers. I really appreciate this :)

Sadly, my problem is still present. After I fully uninstalled the Killer E2200 Ethernet card (+ drivers) and the Intel AC Dual Band AC Wireless-AC 7260 (+ drivers),

my Wireless Network did not reconnected itself for some hours. But I guess that was just luck.

Yesterday, I had the same issue multiple times again.

I also took screenshots from the eventvwr, maybe this helps further. If you don't understand the german eventlog, please let me know. I tried to translate the event logs under the Imgur images, as well:

Do you have any other suggestions? After searching through some online forums with the info of the eventvwr in mind, i found some examples of ppl with the same problem like me.

For example this one: https://communities.intel.com/thread/109381

Thanks in advance and best regards,

Have you tried falling back to driver version 18.20? That was the only thing that worked for me with the AC 7260. If I try any newer version, the wifi goes up and down constantly. With this old driver, I am getting over 400Mbps on AC and 180 on N.
I have to make sure windows doesn't update the driver, but it's only tried to do it once.
