Network Connection Problem

By Kimberly.Stohlmann ·
We changed over from a 10 base hub to a 10/100 switch. We lost connection to 3 out of 5 systems. When plugged into 10/100 switch those units do not connect to server. When plugged into 10 base hub, those systems connect fine. All wiring is cat5 or higher.

What happened?

Some 10MB devices seem to lose the connection after a while if there is no data flowing to a 10/100 switch. The switch swithes to 100MB and 10MB device stays at 10MB.
I think you can best set the switch port to 10MB, if you have a managable switch, or be sure to keep some data flowing every few minutes.

Have fun,

Auto Detect

Some Vendors equipment does not do well with certain switches. Try making both the port on the switch and the PC device Full/10 and it will stay that way. They don't operate wellon the Auto Detect settings.

switch port

YOu need to configure the port of your switch from 100Mbps to 10Mbps. This should solve the problem and work perfectly.

Check NIC settings

by chriswilds In reply to Network Connection Proble ...

Have you checked the settings on the network cards? I've frequently seen issues connecting that are fixed if you change from say, Auto Negotiate to 100 Full, or in your case maybe from 10 Half to Auto Negotiate.

Hope this helps
