we have 20 new PCs being setup in a conference room. We have only 5 jacks in the room wired to our ethernet switch in the wiring closet. The powers that be want to just buy a 24 port switch, plug the new PCs into the switch and use 1 port on the switch connected to 1 of the existing jack that goes back to the switch in the wiring closet. The switch in the wiring closet is connected to a router to the internet and internet browsing is going to be a big use here. My concern is that performance will suffer due to all 20 PCs going through 1 port. Shouldn't we at least buy five 4 port switchs and make use of all 5 jacks in the conference room.
Or, connect a wireless router to 1 of the jacks and put wireless NICs in the PCs (Vista Home Basic o/s). Does that buy us anything? Thanks for any advice and please let me know if the scenario needs clarification. TIA
