I don't know where to post this really.

 

Greetings,

It's a while i'm having this problem but right now it's becomming untolerable.

When pinging my modem i get 90% of values with a time of 2 to 5 milliseconds, which would be godly amazing. BUT the remaining values are either timed out or 400+milliseconds, and they totally happen at random, with some time a 20-30ms which wouldn't be an issue.

Why is that occurring? Can i do something?

 

Notes:

My computer is connected via wifi, i can't use a cable. And let's avoid all the "are your internal fans clean?" stuff please. For the wifi i'm using a netgear device (N300 wifi USB adapter) with up to date drivers. Fluctuations in ping occur independently of the amount of obstacles without the usb adapter and the modem.

It looks totally different to me. He has a regularly repeating pattern, my problem happens totally at random

It may look different but reading it, and the links within, may give you some clues.
