It has 4 x 10/100 ports. You'd get nothing of value out of Gb ports on an L/XL package. So they might as well keep the cost down.
thanks for your reply. " You'd get nothing of value out of Gb ports on an L/XL package." i knw, makes a big difference when transferring stuff in LAN
Do what I do then, feed the output from the hub into a gigabit switch so the network is all 1Gb and the inernet feed into it is 100Mb. That way you have the speed of the LAN with the speed needed for the net.
