Computer Manually Disconnected from network

Hello all, a while back ago I upgraded my internet, then had to downgrade it. After it downgrading it still works, but an annoying issue happens whenever the internet goes out, or when i start up my computer. The yellow triangle is on the connection sign (wireless) and the internet wont work unless I run the troubleshooter, which it gives me
"This computer was manually disconnected from "Yukon****"(my wireless network)
"Problem with wireless adapter or access point" (this one doesn't show most of the time)
Most of the time when it detects them it says detected and the problem goes away, but it can be frustrating as it doesn't always work on the first time troubleshooting it, and have to do it multiple times.

So if you can help, it would be much appreciated, thanks.

Welcome to the Seven Forums.

Let's try a simple thing first:
Wireless Network - Remove
Restart and reconnect (re-enter your key to connect).
Restart again as a test.

If that fails, then update or re-install the drivers for the wireless network adapter.

Thanks for the response, sorry it took so long to respond but after doing that i cannot access
My internet while all others in the house can and am forced to write this on m phone

Can you connect via LAN cable?
