Not a big brand. They used to make modems, and they make low priced networking stuff. I have a managed Zyxel 16 port gigabit switch that I got for $99 early this year, have not had a single issue with it.
Heard of them. Not bought anything from them. I remember them as modem makers also. I bet gigabit switches are commodity parts that can be built easily. Isn't that the reason we have Woven networking gear?
