unstable connection / ping

[grim9x8]

Recently i've been having problems with my network most noticeably while playing league of legends. My ping will fluctuate between the 12-100, and it feels like my input delay is extreme even for the ping.
i'm on wifi with a wireless card. i've tried installing new drivers but it didn't result in any noticeable change so i rolled them back.
this has been going on for a couple of months it used to be remedied by a quick restart but that no longer works, and the network trouble shooter does nothing other than reset the access point.
ive tried running the hex tech tool kit (leagues of legends trouble shooting program) but it didnt seem to help.
i appreciate any advice.

I'd first recommend a new wifi card. Their pretty cheap and could easily be the culprit here.

would swapping to a wired connection fix the problem if its just the wifi card?

Yes, That would definitely correct the issue if it is a Wireless Problem. if you don't mind me asking, what router do you have?

Okay gotcha. I am not very familiar with the Orbi routers, I have heard great things about them though.
