Hey all! Around 7 months ago I ended up relocating for some family issues, and I went from a wired to wireless connection. Everything was working fine until a few days ago. Stuff like Discord, or browsing videos on YouTube, etc; work completely fine, but I'm getting these frustrating frequent small ping spikes. So playing games like Rocket League, Modern Warfare, GTA, so on and so forth cause me to lag and are just enough to ruin the experience. I'm no means a networking expert but I try my best but this issue just stumps me.

I started out using "ping 8.8.8.8 -t" in CMD and watched the process, and for the most part it'd come back with 20-35ms for most hits. But for every 6-12 pings, it was very random when it'd happen, the spikes would go to 80-130ms, and then return the normal. I would occasionally get a request timeout but I figured with it being on WiFi and being a decentish ways away from the modem that it's expected, unless that in itself could also be an issue. I also ran the prompt on the computer downstairs that is connected directly to the modem and it would consistently hit 18-32ms and never spike in ping or timeout a request.

So I searched around Google for possible solutions for the specific adapter itself but didn't find any. So I tried going into device manager and toggling off the "allow the computer to turn off this device to save power", as well as going back into CMD and using "netsh wlan show settings" and then using "netsh wlan set autoconfig enabled=no interface="WiFi" to disable the adapter sniffing for another connection while connected to the home network. But neither have those have fixed my issue.

I am at my wits end because I don't know what else I can do. Maybe I'm missing something that I can fix, or it's a hardware issue with the adapter itself. I don't really have the option of hardwiring directly from the modem to my room at the moment. Any help would be appreciated as I genuinely can't think of any fixes. Thank you in advance!

I can accompany screenshots of stuff needed as well.
