One thing to consider is I've heard bad things about the latency,
jitter &
throughput of these USB Ethernet adapters, if I get round to it later
I'll run a
test but it may be worth figuring out if the existing Ethernet port on
your
device supports vLANs.
That is exactly what I didn't want to hear, but thanks for the warning.
High latency, jitter and poor throughput would be bad news because this
NIC must handle all internet traffic from the LAN - admittedly 3 or 4
computers at the most, but still.
I'll look into vLANs.
I also have the possibility to install a wireless NIC, although looking
in the computer manual, it doesn't make it clear if it replaces the
cable/RJ45 NIC. If it is in addition to the RJ45, I could use that as
the solution.
Thanks

well I ran some tests yesterday and my results confirmed these ones
http://rednerd.com/2010/11/16/asix-ax88772-usb-ethernet-adapter-performance/
so we know that chipset at least is OK. What is this chocolate box
computer? What architecture? ARM? x86?
A USB NIC will almost certainly use a but more CPU than one on some
other type of bus, your best bet is to set it up inside your network &
have a computer either side of it run iperf & see what kind of
throughput you get.
Good luck, let us know how you go, & do look into vLans as they are a
very elegant solution, particularly if the box in question has a gigabit
NIC.
