I've been facing a frustrating issue with my custom-built PC that has been running perfectly for over three years. Lately, I've been experiencing significant ping spikes every ~10 seconds while using WiFi. It's not my ISP since I moved to a different provider, and nothing has come close to fixing it despite extensive searching online. This started about a month ago, so I'm not sure what's going on. Interestingly, around the same time, my monitors flicker off and back on occasionally, which feels connected. I'm at my wit's end trying to troubleshoot the cause. I've checked for malware, updated all drivers, and it seems to be an issue with my PC since both upload and download speeds drop during these spikes. I'm considering whether my wireless card might be failing, or if there's a PSU issue, but I can't pinpoint it. Any advice on diagnosing or solving this would be greatly appreciated!

Update: I swapped out my wireless card with one I borrowed from my dad, and it completely fixed the issue! I guess my original card was the culprit. Now I’m wondering if it could also fix the screen flickering I was experiencing. Thanks for the help, everyone!
Before you go swapping hardware, you might want to check if your device is searching for other WiFi networks every few seconds, which could cause lag. Try running this command in the command prompt: `netsh wlan set autoconfig enabled=no interface="your wifi network name"`. It might help reduce those spikes.
It might also help to test your default gateway with a ping test. If you can see consistent spikes there too, it could point to your router rather than your PC.
Good idea! Check your router first before diving into PC parts.
Sounds like it could be your wireless card acting up. Sometimes, WiFi adapters go haywire and cause these kinds of problems. Have you tried using an ethernet connection to see if the issue persists? That'll help narrow it down.
I plan to try Ethernet soon; it’s just a hassle to set up. But I agree, that could be a good test!
I tried it but got an error about privileges. Running it as admin fixed it, but sadly it didn’t solve the lag.
