Re: Gigabit Switch

Thanks MK and Joel,

My LAN is small with about 20 office users (some wifi access) and a 
computer lab for students with 12 PCs as well as wifi access (to be 
added at this upgrade). Application is just Internet access and a shared 
server for office staff. There is no technical staff like System 
Administrator so no need to have "managed" feature set. It is more 
important that the switch is reliable since it will be running nonstop. 
I am looking for gigabit speed to speed-up copy recorded large video 
files to and from the server is rather slow now with 100BASE-T speed 
although still bearable.
