So basically, I can surf the web, message friends via Discord etc. When I try to call people on Discord, I get 'No Route'. I cannot connect in online mode to steam, or join a multiplayer game in anything (i even tried minecraft, without luck!). So, I've tried unplugging my USB WiFi adapter, restarting my PC, disconnecting then reconnecting from WiFi, and resetting the router, all without luck. Ethernet is not an option for me, so I have no idea what to do! Please help!!

When you can surf the web it means most things are correctly configured. If it was something simple like subnet mask nothing would work.

So first I notice that IPv6 is active. Most ISP do not support this but if you have one that does you may be using ipv6 connections. IPv6 is not supported by many things so it is not uncommon for some to work and other not to. It should switch to ipv4 for those things but not always.

I would try to disable the ipv6 support in the wifi nic settings.

The other common thing that causes this is the firewall on your machine. Many times it will set the network type incorrect and decide that your pc is directly on the internet rather than on a home lan. It by default puts in different rules...

I've tried it on my laptop, and it still cannot connect to any of the services I mentioned above.
 

Yes, I am on my own WiFi.
 

My bad! There is xfninitywifi for me and I was looking at the difference in ipconfig's. Accidentally sent the wrong screenshot. Here is the real one with my WiFi.

Many times only web surfing works no other ports are allowed. I would see if disabling the windows firewall temporarily makes any difference.

It could also be things like proxy or vpn if you have ever installed either of those, many times they do not uninstall cleanly.
