Is My Wireless Dongle Dying?

Hello,

I've been having some frustrating wireless connectivity at my PC recently, and seemingly only at my PC. It began about a week ago, with Discord calls intermittently spiking to 3000 - 5000ms ping. Since then, the PC has struggled to stream, game, or even load web pages.

At this point I have replaced the router and put in a range extender (was previously using homeplugs) and connectivity for all devices has improved; except for my PC.

I presume it is the wireless dongle I use finally dying. [Here](https://imgur.com/a/tDSUNOs) is a picture of my network performance via task manager as it downloads a game from Steam. Is my assumption likely correct?

Thanks!
