Ok guys this is the problem.
I recently i upgraded my internet from 5mb/s to 30mb/shttp:/www.speedtest.net/result/1455479891.png ">www.speedtest.net/result/1455479891.png
The problem is when just 1 laptop connects to our network i get serious lagg on xbox live. I have 3-2 stripes and later on it turns in 1 BAR
My internet speed cant be the problem. I'm using an ethernet cable which is connected directly to the modem. And when the laptop uses the wireless option from the modem and router in 1 i get the lagg on my xbox live experience.
Is there a way that my xbox get 1st priority from internet so the laptop just gets the slow internet? I cant shut the laptop down because my sister uses it.
And help would be awsome!
