For our network we have a Juniper Networks SSG20 Firewall unit which is connected to a T1 utilizing a Netgear FS524 24-Port 10/100 Switch. We have a total of 10-users in-house (some of our users are connected via ethernet with the majority of our users connect wirelessly) and I've noticed a degradation in performance going from 1.5Mbps to as low as 26Kbps. I know for a fact that some of our users are uploading/downloading videos and streaming news sites. I know the quick fix to this problem is to increase our T1 bandwidth to at least 3Mbps or faster but I also would like to know if I were to replace our Netgear 10/100 switch to a 10/100/1000 gigabit switch if this would resolve my performance problem before we spend the money to increase our bandwith?
Your response is greatly appreciated.
