Has anyone experience using USB3 to ethernet adapters ? I need an extra
interface but my HW (Intel NUC) does not have room for another card).
Anything recommendable?
Best regards, Frans.
Hi there,
I´ve tried once an USB Multi-function Lan Adapter (it´s also a UBS3 HUB) with
PFSense, 2.2.x.
I´ve connected the internet on it, and used onboard NIC as LAN Interface. I´ve
experienced some strange behaviors,
like some instability on the internet when traffic has raised. Some logs was
showed on the screen by the time the problems occurred.
It was a test to a client, so I´ve replaced the machine to solve those
problems, but I believe I was using a cheap
adapter (I can´t tell you the manufacturer, because it doesn´t say on it).
In general, all USB ethernet adapters will be at least *slightly*
unreliable, regardless of whether it's USB3 or USB2.
Your best bet is:
a) find one with a well-supported chipset in FreeBSD (this is *much*
easier said than done, sorry...)
b) connect it as close to the on-board USB hub as possible; on some
motherboards, the USB ports around the case are not all equal; some are
multiplexed via an extra internal (on-chip) hub while some aren't. The
fewer hubs between the core chipset and the adapter, the better
c) find a way to guarantee electrical and mechanical connection.
Consider using LocTite(r) Blue or similar low-strength bonding agent on
the USB port to secure against vibration and gravity. (Also consider
that you can never get all of it off, so don't plan on re-using that
port for anything else later.)
d) disable all USB power management related settings in the BIOS
