USB to ethernet Adaptor

Thu Oct 08, 2015 1:43 am

I'm building a firewall with my Pi B+ model and was curious if any of the USB to Ethernet adapters are usable on the pi? Or which ones work better. I need two LAN ports for this to be successful and sit between the client and router. Thank you in advance :) :D

Many of them work. Try to avoid the really cheap ones on ebay and the like as they use the DM9601 chip set which has a bad bug in the driver (that might have been fixed by now, I haven't bothered to check) and is only USB 1.1 giving you a maximum of 12Mb/s over the USB even though the chip supports 100Mb/s ethernet. They are advertised as "USB 2.0 compatible" which means they will work with USB 2.0 - just not at USB 2.0 speeds :shock:

I've used an AX88772 based adaptor with no problems. It was still quite cheap and a bit more flexible as it has a short USB lead rather than plugging in directly.

+1 (the DM9601 driver issue led to some of my first posts!)
FWIW, some brief notes/images of the devices I've tried out are here:

Note that the USB 2.0 spec defines three speeds ("low", "full" and "high") and that it is perfectly possible for a device to be designed to and compliant with the USB 2.0 specification while only supporting "full speed".

I am looking for a known good USB to ethernet adaptor that does not require power from a hub, anyone got a recommendation (don't care about price, want it to work with my rPi3!).

USB to ethernet Adaptor

Cant you use an ethernet hub or switch? The mcmix/controls are tcp/ip devices so should work through normal Ethernet routing equipment. A USB adaptor doesnt sound like a great idea.
