A week ago, I said that I need to reboot my Thinkpad 755CX with 3com Etherlink III PC card (Combo) running OS/2 WARP Connect if I move one LAN to another. I thought that this was strange, because some people had already mentioned that they carry their hibernated thinkpads from one place to another and their LAN connections at multiple places just work file. Today, I finally found a simple cause for my problem. The two LANs, to which I am connecting my machine, use different types of cables. One of them uses coax cables and the other uses TP cables. After waiting for 35 minutes on the phone, I finally reached a technical support guy at 3com and explained the situation. Then The guy said "It is normal. What you have to do is JUST reboot your machine." I repeatedly tried to explain why I am concerned with this feature, but he did not understand my point. His final comment was that I should talk with the marketing department responsible for the future product feature improvement. The only useful information I got in the phone call was that the 3com drivers only check the connected transceiver at the boot time. When the card service tells the drive to reinitialize the network card, the driver uses the previously obtained information about the transceiver instead of checking it again. The tech guy could not explain why the driver was designed in this way.
