Good afternoon, I have verizon fios internet with a all in one modem/router conected to a server. I have 4 computers connected to this server with 2 computers connect hard line cat 5 and 2 computers connect wireless G. Their are times when all 4 computers are used at the same time and times when their is only 1 person on a computer. with this said we always have the same propblem. In the morning the network and computers work good, through out the day at some point the computer will freeze up or very slow. will have to shut computer down and restart and then it works fast again. Also one on the computers is a brand new dell with plenty of running memory.
