What is my network speed? How can I increase it?

Configuration:1 server with 1000 Base T nic card
15 Windows 7 computers with 1000 Base T nic cards
4 XP computers with 100 Base T nic cards
1 router with 100 Base T
48 port 10/10/1000 Base T managed gigabit switch
All are connected by Cat 6 cable

From what I understand - the network will run at the "slowest" nic speed of all devices connected to the 1000 Base T switch

Goal: Have the network running at the max nic speed of each computer.

What are your thoughts?

That's not 100% correct...each device will run at its rated speed...so the 1GB nic's will run at 1GB...the 100Mb nics at 100Mb

So your pc's with 1GB nic's will transfer at that speed to the server - long as both are connected to the gig switch

That was true when we used Hub and not switches.

Each port on a switch is unique pipe and flows are the spend of the nic on the pc provided the switch has a port that matches or greater than.

Check the lights on your switch to make sure they registering the ports at the correct speed most managed switches have lights with different colors to tell you what speed the port is. Thru the GUI of the managed switch it will show you also.



Where's your server connected? To the Gigabit switch or the router?



every device must be using gigabit Ethernet, gigabit Ethernet port, gigabit switch and if compatible enable fat channel



It seems that smckeown777 and trgrassijr55 are on the same page. Yet, nattygreg, has a different opinion.

Which is true:All devices must have gigabit Ethernet nic card
OR
I can have a mixture 100 / 1000 connected to the gigabit switch and each will operate independently at the speed of the nic card in that device?
