Acer Veriton N260G
I want to use Acer Veriton N260G (Intel Atom N280, 1.66 GHz, RAM1024MB, HD160GB, LAN WLAN; https://www.engadget.com/products/acer/veriton/n260g/specs/) for a personal router/firewall. Because this computer have only one LAN, I want to buy an USB to Rj45 adaptor (http://www.emag.ro/adaptor-a-usb-3-0-to-rj45-aglnu303/pd/DNX7G3BBM/) for second LAN.
Why do you think, will work?
The performance is likely to be pretty bad, and USB network adapters can be unreliable. If your connection is slow enough it might work. If you don't have the computer yet, get something else. If you're trying to reuse a computer you already have the easiest thing to do is just try it and see if it performs well enough for you.
