Windows 10: having Ping spikes all the time and random disconnects from my WIFI on my PC

So, my WIFI on my PC has been having issues since and I really dont know how to fix it. I always get ping spikes and even sometimes disconnect from the WIFI. This especially happens a lot when my brothers PC is on his PC. The thing is, ive even played online games with my brother, and he seems to have no issues about disconnects and ping spikes, while I was disconnecting several times. I have the same WIFI stick like my brother and i even bought a new one for the thought that the issues were coming from my last one, but im still getting the spikes n disconnects. Any help would be appreciatable

Random Ping Spikes

As of two days ago, I have been getting random ping spikes. I have done speed tests, and get normal speeds, but when I ping my router or other sites, such as Google.com, Ill have random spikes of up to 400ms. It will be a stable 1ms when I ping my router, but will randomly spike to ~400ms at random intervals. Any help is appreciated. I can supply any screenshots if necessary.

 

random ping spikes

i get lots of random ping spikes. they dont happen all the time but maybe once evry 2 days and last hours. when i type ping (my ip) -t in cmd it says "request timed out" every time i spike. none of my other devices seem to experience this issue and i even
got a new antenna and its still there. it might be my router but i dont think so. what should i do?

 

Random High Ping Spikes

So, I decided due to other issues I was having, and low storage space to reset my PC. The issue was solved that way, I'm no longer experiencing random ping spikes.
