Networks extreme Lag

Dear fellow Bit-techers

Over the last 24h's or so, when using any application that uses an internet connection, on the desktop im using. I get points when there are extreme lag when nothing will happen, then the internet will start working again. and over and over it goes. I don't know what has caused this or how to fix this. maybe one of you has a solution.

Thanks

Adam

Have you checked your machine for malware?

 

I don't know what caused it but its gone, could just be the ISP being F**Ked up. swept the computer for malware and virusing and all that crap but nothing found. did give me time to go though lots of old files and delete stuff, got rid of 200 GB

 

ping your router, what does it show

Tracert 8.8.8.8 (google public dns) what does it show? any major lag points?

ipconfig /flushdns
