HELP!!!I have a small workgroup, running 2 servers and 6 workstations. The PCs have onboard Realtek LAN ports that run at 10MB with a 10MB 3COM hub, but not at 10MB or 100MB with a known working 3COM switch. I am using CAT5 solid cable with the correct RJ45 connectors, and the maximum cable run is 20m. ANY SUGGESTIONS ON HOW TO GET THE SPEED UP TO 100MB/s?

You never mention if these built in ports can do 100mb. If not then put in 100mb nics.

Did you do a direct connect to the switch with a pc [not using the 20meter of cable]?

I don't know from your post what you have done to point to the problem source. Is it the nics, switch or wiring. Is the wiring new and did you run it?

Thanks for the response...
The onboard lan is 10/100 compatible. The switch has been connected to other PCs and tested fine, and the workstations have been connected to the 10Mb hub and worked fine at this speed. Unfortunately I don't have another 100Mb switch/hub to run any 100Mb tests. I have done the cabling personally, and have confirmed the reliability of the cable, connectors and flyleads.

Its hard to say exactly where the problem lies, as the switch works on another lan, and the existing lan runs at 10Mb with the 10Mb hub.

Have you tweaked the settings of the NIC and set them to 100 Mbps?

are the cards and the router autosensing??? you might have to set them at 100 if not...

OMG, check this out. hubs dont run at 100Mbps, get a switch.
