10/100 Router plus Gigabit switch networks

by johnc2994 / February 25, 2013 7:59 PM PST

I have a Zyxell Modem/Router with 4 ethernet ports running 10/100, if i plug a gigabit switch in to this and then plug 3 PC's into the gigabit switch, (each PC has a gigabit NIC) will the router pull the network down to transfer all data at 100mbps or will the PC's continue to transfer at 1000mbps and only the connection from internet router will be at 100mbps.

Everything stays at 10/100 i.e: B/G. All hardware must be gigabit/N and cables should be CAT6 not CAT5, and then good luck in attempting to achieve 100mbs, GIGABIT set up or not.

In reply to: 10/100

I see what you mean, so just to confirm, if i have a 10/100 modem/router plugged into the gigabit switch, which is in turn plugged via Cat 6 cables to the 3 gigabit NIC PC's, then the data transfer between the PC's will be at gigabit speed and the data transfer between switch and modem/router will be at 10/100.

Sorry to go on but i have been told (and don't believe) that whatever i do the network will drop to the lowest denominator on the network . e.g. if there is one component on the network that is 10/100 then the whole network will run at that speed.

Will not slow down entire wired network.

The reply from pgc3 above is confusing wired and wireless networking.

No, your entire wired network will not slow down because of your modem/router being plugged in to your Gigabit switch. As long as the 2 devices communicating and devices (e.g. switch) and cables in between are gigabit capable, your connection between the devices will be at gigabit speeds.

I love that!

One of the best kept secrets to boost your wired network speed is to put in a switch after the router and put your gear there.

No it won't magically transfer the WiFi to higher speeds but it will improve the network overall.

Your question reminds me of what happened long ago on DUMB HUBS. This is a switch, not a dumb hub. As what a switch does is well discussed, I'll stop here.
