Gentlemen:

I'm seeing an HS220 coming and going in app status.  Including Beta.   Interestingly, it showed -73db down, was dropping 3% of pings, and was averaging 164ms ping response time.  162 packet test from a PC.   (Testing from the router is similar)

A simple restart of the affected switch delivered:  -44db, 0% loss, and 7ms average response time.  134 packet test

Fellas, respectfully, this suggests your network drivers are... ahem...  not too stable.

Hardware version 3.0, firmware 1.0.3.

Please advise any updates on upgraded drivers.

May I also suggest you develop a routine by which we can command a switch restart for all switches?  It seems these devices would benefit from an occasional restart and I don't much care for manually doing same.
