Windows 10: wifi connection constantly dropped

I have two machines, MSI GT80 SLI. They are configured identically hardware-wise.

MSI GT80 One: disk 1: Has dual boot Windows 20H2; disk 2: the previous version of 1909.

The 20H2 install has issues with the Killer 1535 wifi card. Constantly drops the connection. The 1909 version has no such issues.
Before I upgraded, I cloned the OS via Macrium.

MSI GT80 Two: Dual boots Windows 20H2 and a non-Windows OS. The 20H2 has no issues with the wifi card dropping the connection.

There is something specific to GT80 "one" machine 20H2 that breaks wifi. I thought it was hardware but it never is, since the previous 1909 installed on the very same box runs OK.

I compared both 20H2 installs on both machines and they look identical. Same patch level, same driver version. Machine "one" installed 20H2 today and machine "two" 20H2 got installed a month ago. Same startup programs, same everything. One works, the other does not.

I am not sure when wifi stopped working, it could be the 20H2 upgrade has nothing to do with it. Since the first 20H2 install works fine. But on the second 20H2 install, wifi works intermittently. It will work and then drop the connection without recovering it.

sick of my laptop internet being slow and dropping constantly

I have the same problem here. Two Windows 10 tablet/laptops (one from Lenovo, the other from Acer) will drop their wifi connection constantly. The network environment seems not to affect the issue as at least Acer drops the connection with other Network as well. Usually troubleshooting wizard helps (resets wifi adapter), sometimes reboot is needed, sometimes the issue goes away by itself after a couple of seconds.

During the network problem, the available networks (SSIDs) are listed normally, but no data is really sent to network.

 

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

 

Wi Fi connection constantly dropping

I have an HP 17 X173 dx with Windows 10 already installed. My wifi connection drops constantly. It dropped twice while trying to get to this point of writing this post to the community. Seeing lots of posts about Wifi but most are older posts from 2016.
Was hoping to get some fresher info on this issue and how to fix it.
