the school lans in our district are currently 10mb shared, and we plan to pull out all hubs and replace with switches to create a 100mb switched environment... each school will have new pc's throughout, and new servers are going in, too
while we were in the mood, we thought we would upgrade our school routers. each school has a t1 circuit that talks frame to the district office through a 5-year old 2524 that connects to the lan via a 10mb rj45 port... our thinking was a new router with more ram/flash would have to give us a nice kick...?
recently got the following interesting advice: upgrading the routers is not necessary and would not significantly improve network performance on the lan side or between the wan links b/c the t1 data circuit at each site (which will not be upgraded anytime soon) is a bottleneck that a new router won't do much if anything to improve.
if true, would love to save the money and spend elsewhere. would appreciate any comments. mtia

decision. To do this we require the switch to do...
