Rated 5 out of 5 by Good Hojjamighty from Fast Ethernet over USB 2.0! I am the IT department at my plant: sometimes I need to bypass the corporate net and get outside with a little speed for a quick download, right? With this adapter, I can run two totally separate networks on one machine. Since it's USB, I can even make it available to a virtual machine while hiding it from the host! Driver is tight and high; no junk installed, no foolish systray processes bogging your works; just good solid ethernet access. Great Price, Too!

Rated 4 out of 5 by Rob from Easy way to add Ethernet Connectivity Best and easiest way to add connectivity to an additional network that is isolated from your company network for development of networkable devices.

Rated 5 out of 5 by Bob from USB 2.0 Ethernet Option a Lifesaver The USB Ethernet cable is a must for those computers that came without an Ethernet card and port installed. Saves a trip to the shop to have a port installed, and is easy to use, either with a DSL Modem or a Router, which was how I used it to hook into a late model PC that had no Ethernet Port in place.

Rated 4 out of 5 by Proceed with caution from Worked but lost latch for Eth. cable under tension It works great and is easy to use, but be careful not to place it under continuous tension. I am on my 2nd one because the 1st one lost its ability to grab onto the Ethernet cable. It had been positioned with the cable hanging down from it or sometimes stretched out, so I guess that put slight but constant pressure on the piece that latches the cable in place.

Asked by: alternator
No. This must be connected to a USB port on a computer and then connect the RJ45 port to a router, switch or modem.

I have received a new computer that does not have a cd/dvd player. The unit came with a disc. is there a link to a down load for the information?
Asked by: will
The drivers for that device are on the products page on our website. Just put in the part number in the search bar and once on the page, they will be located at the bottom. We have both Windows and MAC drivers.

I have a 12" digital photo frame. Is the 7.5in USB 2.0 Fast Ethernet Adapter Cable the wireless adapter the correct item for this frame that is sold separately for it.
Asked by: Kathy
Unfortunately I would say that this is not the device you need. Our device requires a PC in order to work properly. I would recommend contacting the Manufacturer of the Photo Frame and see what device they recommend.

We use a device in our designs that requires a USB to Ethernet adaptor. The manufacturer specifies that an adaptor be used that has a ASIX AX88772 Chip set. Does this unit or any of your units use that chip set? Thank you

This unit now uses a Realtek Chipset.
