WiFi not working on windows 10, connects but no internet.

As you can probably tell by my username I have exhausted all efforts, i've been trying to fix this for 2days now, installed/reinstalled 4 different OS trying to fix it and I cannot find a solution, it always worked before.
Basically when I connect to my router I get full bars and its showing as connected with internet, if I go to do ANYTHING at all that requires an internet connection (opening webpages, downloading) etc. it just says no internet connection, OCCASIONALLY it will go very slowly for a while before ending itself again. Also if I try to connect to my phones hotspot it connects fine and everything works.
Other devices in the house work fine, other laptops, phones etc. all connect fine. The most mind boggling thing about this is it works fine in ubuntu, I can connect to my wifi fine and everything is good, but on windows 7/8.1/10 it does not work (yes i formatted numerous times installing these OS and it took me forever and a lot of lost data). Some more useful advice: when i just install windows it works fine, but as soon as i restart it no longer works.
I have tried so many things its hard to list them all but i'll try:
troubleshooting, ipconfig /flushdns, netsh stuff, reinstalling OS, disabling and re-enabling wireless, reinstalling drivers, resetting router, checked that my mac address wasnt blocked.
If anyone has any idea please let me know, I greatly appreciate it.
This is what my network activity looks like in task manager:

Have you tried disabling IPv6, NetBIOS, LMHOSTS and using a custom DNS? Run CMD as admin and copy:

Code:

netsh int ipv6 isatap set state disabled
netsh int teredo set state disabled
netsh interface ipv6 6to4 set state state=disabled undoonstop=disabled
reg add "HKLM\System\CurrentControlSet\Services\Tcpip6\Parameters" /v "DisabledComponents" /t REG_DWORD /d "255" /f
reg add "HKLM\System\CurrentControlSet\Services\NetBT\Parameters" /v "EnableLMHOSTS" /t REG_DWORD /d "0" /f
wmic nicconfig where TcpipNetbiosOptions=0 call SetTcpipNetbios 2
wmic nicconfig where TcpipNetbiosOptions=1 call SetTcpipNetbios 2
wmic nicconfig where DHCPEnabled=TRUE call SetDNSServerSearchOrder ("208.67.222.222","208.67.220.220")

Also setting up IP manually and removing all network protocols, except IPv4? So it would look like this.

I have tried this now and it didn't help, however this time when I re-installed windows it was different, I disabled automatic driver updates and my wifi worked fine for a while, i even tried restarting and it still worked. However after using it for maybe 5mins or so it just suddenly stopped again.

Edit: WiFi works now (for downloading steam at least), however it's extremely slow when it is fine on other devices. It is too slow to browse the internet and it just says no internet connection if I try, however downloading it has speeds in the Kbps. This is not an issue on my 4g hotspot which has completely normal speeds, so I don't think its a problem with the wireless card, especially considering it works fine on ubuntu.

Edit 2: screenshot of network activity to help understand the problem

Edit 3: Forgot to mention that occasionally it works fine and the download speeds go up but after 3-4 min it drops down like in the screenshot and stays that way for a long time before suddenly working for a moment again
