I've been having terrible trouble with packet loss and latency with my USB wireless adapter for a while. No other computer on the network has this problem so I updated drivers and I reinstalled windows and still the problem persisted.
Finally I noticed that unplugging my USB HDDs resolved the problem. I felt this was rather odd as the packet loss and latency happened even when the hard disks weren't active
Is this to be expected? Is this an unavoidable consequence of having a large number of USB devices? Is there anything I can do about it?
