Hey fellas i have a question, ive asked a few people what the cause might be but no stright answer so far, if this is the wrong subreddit please do tell and ill remove the post.

Basically my issue is while gaming, on wifi,( sadly cable is no option for me) sometimes i get lag spikes( seizures i like to call em)

Its a constant 1.5KMS ping spike( no disconnect at all), for sometimes a few minutes or longer), it stays on near 1.5k ms, when its not happening everything is fine and dandy,even outside of gaming,. the network goes on the lag spike for a while, its not slow, its still fast for downloading and such, but its simply delayed,

i downloaded selfishnet to try and isolate the problem, maybe its an upload issue, other devices arent causing it it seems, on selfishnet it shows my pc either downloading or uploading at extreme speeds, ( Im talking like 14000 kbs( which is way more than my network speed),

Any idea on a cause or a fix?
