Ethernet port always at 100mbps on certain switches

[TheDude]

I have a variety of network switches. All of them support 10/100/1000 operation, however my Fit-PC 3 connects at 100mbps when plugged into my "consumer-grade" Netgear switches, and I get 1000mbps when I plug it into my rackmountable Netgear JGS516 switch.

...most of the time.

I don't always get 1000mbps when I plug the Fit-PC into the JGS516, it does sometime connect at 100mbps - but recently it has reliably connected at GigE.

The connection speed is set when the Fit-PC is plugged in and powered on, but before any OS loads. All of my other equipment is able to connect at GigE speeds into my consumer-grade switches - I thought the only functional differences between them and the business-class rackmountable switches was switching speed and the number of ports.

My cables aren't the issue as they're all Cat5e and all my other computers are able to use them to connect at 100mbps.

You may want to check your cable or the connectors on the cable.

Gigabit speed requires all 4 pairs on the cable and connectors. If
you have a flakey cable or connector in regards to those extra 2
pairs of cables, then using that cable would force 10/100Mbps.

Next check the ports, the one of the fit-PC3 and on the switches.
I once had a bent pin inside the connector on a workstation. It was
only 10/100 so it needed both pairs and could not drop speed. But
if you have a bent pin on one of the extra 2 pairs needed for Gigabit
speed, well that's an answer.

Problems like that drove me crazy. Now I have a 8P8C cable checker.

We are unable to reproduce this bug with our switches and cables. I have a stable 1GB connection with my HP ProCurve switch. We will try to purchase your router to investigate your issue
