Wifi doesn't connect unless directly connected to router by ethernet cable

Whenever I unplug from the router and go upstairs, I can't connect to my wi-fi. The problem also persists downstairs unless I am connected by ethernet. It's been happening for about 2 days. At first the wi-fi would jump in and out randomly and quickly but now it simply wont connect. Is it a virus or how can I fix it?

Delete (or forget) the existing WiFi connect.

disconnect the wired connect

enable WiFi and be sure the device is active

look for your SSID and attempt a new connection (allow it to be remembered)

Hi Mininanner22. Do you have another device that can connect to your wireless network in the same location? If you do and it connects w/o a problem, the issue is with the wireless reception on the problem machine. If another device detects your network and can't connect, you could have a problem with the wireless section of the router since you mention that your wi-fi was intermittent.You could try resetting the router if another device detects your network but can't connect, or seeing if there is a firmware update for your router and trying that. Weather another device can connect when the other can't will tell you where the problem could be.
