About seven years ago I wired the house with cat 5 cable for my network. All has been running well since with cable internet through a linksys wrt54gs router and 10/100 switch for the computers in the basement. Currently I have 3 computers hooked up to the network all gigabyte lan capable. Will I will have to upgrade to cat 6 cable, get a gigabyte router and switch to take advantage of of the gigabyte transfer rate? Will my internet service be any faster (download upload speed)? It will cost a couple hundred bucks+ to buy the equipment and cable plus my time to install. Is the cost of upgrading my network worth the increase in speed?
