"Re: USB 3.0 interference (Mac Mini 2011 server owner)
I saw something pop up in my RSS about USB 3.0 causing interference with 2.4Ghz. (Reminder on potential USB 3.0 interference w/2.4GHz Wifi/BT in Feb 27th news after seeing another report of problems.)
I have one of these on my Mac Mini to get USB 3.0 (Kanex Thunderbolt to eSATA + USB 3.0 Adapter). I'm using it with this USB hub (Anker USB 3.0 SuperSpeed 10-Port Hub - link notes "VIA VL812-B2 Chipset and updated Firmware 9081").
It works remarkably well. However, if I put something really high speed on it, like a hard drive, (and it's only the USB 3.0 side that does this, eSATA doesn't make it malfunction), my Apple Magic Mouse and WiFi both slow to a crawl.
I have scratched my head over and over until I figured out that a mass storage device using high speed mode on that USB 3.0 port was causing the issue. Now that I have the external connector using eSATA (which is just about as fast to me), I can use my Magic Mouse just fine. But, if I connect a portable USB 3.0 drive (like this Seagate Backup Plus 2TB Portable HDD STDR2000100) and try to do a large transfer, guess what? Same issue. Mouse slows down to a crawl. Wired mouse works fine. Yeah, it's kind of frustrating.
Only advice I have is the usual (move USB3 devices as far away as possible, shielding (cables, devices), using 5GHz wifi if you have an 802.11n or ac base). Where possible, I prefer Ethernet.
