I just moved to a new apartment, I used to have AT&T, but now I have Xfinity. I pay for gigabit, and my download speeds are always fine, and my ping times and upload seems reasonable, but at random points in the day things just stop loading and a few minutes later its fine.
I've tried other devices in my house, they seem fine, but then when I go back to my computer its OK already so I don't know what the issue was.
Because its so transient and lasts only a few minutes at a time, I don't know how to debug it.
