Windows 10: Default Gateway not Available since switching to windows 10

I switched to windows 10 about 9 months ago and ever since my connection has been dropping in and out, It gets better when I reset my modem but even then it is slow, My network adaptor is Realtek PCIe GBE Family Controller, I am connected using ethernet through the power line but wifi with an external usb adaptor doesn't work either. Troubleshooting says Default gateway not available, it usually says not fixed, although once it randomly said fixed.

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

 

Windows 10

Should Micosoft not be fixing the problems with windows 10 as it seems a lot of people are having this " The default Gateway is not available" since upgrading. I myself have spent hours trying to get my internet back on as it keeps going off comletely or
limited assess available This has only happened since I upgraded to Windows 10

 

I had this exact same issue with a Dell laptop which has an Intel wireless adapter.

What fixed it for me was changing the Power Saving options for my wireless adapter to Maximum Performance. You can follow the steps in this article: Fix Wireless Limited Access Default Gateway Not Available Windows 10 - TeckLyfe
