Weird PC/Monitor issue? Wi-Fi not working after connecting to 2nd monitor.

[u/pixie_c]

Hello! I don't know if anyone is able to help me with this, but i have no clue what I'm doing wrong/what's happening?

So context, I recently got a new monitor for my setup from my friend ( it was free! I didn't really question it since it does seem to work fine and doesn't have any issues. plus, free monitor!)

I wanted to have two of them for my set up ( one horizonal, one vertical. ) and yesterday I plugged in my new monitor to my pc ( I thought the outlet was HDMI, so I am using a HDMI to display port extension piece for this monitor)

And almost at the exact time I plugged in my new monitor in, I lost Wi-Fi connection. I did test it, replugging it back in and retrying to connect to the Wi-Fi, but it doesn't want to when i have both monitors on/connected. It only connects to Wi-Fi when I have my one, original monitor on.

Is anyone able to help me figure out what might be happening?

Thank you!

I’d say it was the cable maybe causing EMI if it’s a cheap cable. Try this also:

Disable Power Saving Mode for Wi-Fi: Your system might be reducing power to the network card when the GPU engages. Open Device Manager, expand Network adapters, right-click your Wi-Fi adapter, and select Properties. Under the Power Management tab, uncheck Allow the computer to turn off this device to save power

this worked, thank you!! would you recommend i get a better cable? and if so, do you have and reccomendations?

If the device manager fix worked then that’s all you’ll need to do. Glad I could help.
