Windows 10: Can't stay connected since update; Default Gateway Not Available or No Internet is primary...

For some time after a Windows update, I have found that I can't stay connected more than a minute or two at most.

Network Icon will show "No Internet", Using Windows troubleshooter gives "Default Gateway Not Available" most of the time.


My PC is all but useless for using the internet... Any help is appreciated.

Default Gateway not available

The "default gateway not available error" occurs frequently when connected to my ISP's modem. This causes the internet connection to drop frequently and I have to run the troubleshooter to restore connection. I have gone through
all of the steps in the article

Fix network connection issues in Windows

The problem persists.

 

No internet found after switching WLAN connection, Default Gateway not updating

After the previous update on my Lenovo Z51 running windows 10, I've found that switching he wi-fi connection to any other network causes the network to appear to have "no internet connection". Troubleshooting the network fixes the problem with the message
"default gateway not available - fixed". This happens every time I switch networks regardless of which network I connect to or whether I've connected to that network before. The problem seems to be that the default gateway doesn't update when the network is
switched.

Here is the "default gateway" part of the "Wireless LAN Adapter" output of
ipconfig during different conditions:

Normal, working connection to network 1:

Default Gateway . . . . . . . . . : fe80::1%18

192.168.1.1

After connecting to network 2, no internet found:

Default Gateway . . . . . . . . . : 192.168.1.1

After running network diagnostics, "default gateway not available - fixed":

Default Gateway . . . . . . . . . : 192.168.0.1

After connecting again to network 1, no internet found:

Default Gateway . . . . . . . . . : fe80::1%18

192.168.0.1

After running network diagnostics, "default gateway not available - fixed":

Default Gateway . . . . . . . . . : fe80::1%18

192.168.1.1

What seems to be the problem and is there any way to fix this? I am constantly moving around and frequently have to connect to different WLANs.

Ethernet connections do not seem to be affected

The laptop is dual booted with Linux, which has no problem switching networks, hence the
network interface card is working fine
