Interned slowdown in the evening.
I am in Las Vegas, NV and in the last three weeks have strange problem: I'm paying for 150Mbit Internet. During the day the speed is mostly around 150-170. In the evening, around 6PM, it slows down and by 8PM yesterday it was 20Mbit. At about 9 or 10PM it goes back to normal.
Tech support has no clue what it is and want to send out a technician, but the is during working hours when everything is running well.
Any ideas what might be the problem?
