Switch - cable problem
I setup a small office network with 2 computers runing
Win98SE and 1 computer runing WinXP Pro. Computers are in two rooms. Between rooms is one UTP network cable 15m long that connects 1 computer with Win98SE with other two. Other two cables is short (2 m). I use LevelOne switch to connect computers together. The problem is this: when I place the switch in room with separated computer (Win98SE) and connect him with one short cable and 1 other computer in other room with the long cable, the network works fine. But, when I place the switch in room with 2 computers (Win98SE and WinXP Pro) and connect these computers with the short cables and computer in other room with the long cable (the same one as above), the network is established only between computers in the same room; the computer in other room is not recognised. It seems that the long cable works only if the switch is connected-placed in the room with 1 computer. Where is the problem? Is it possible that the long cable work only in one direction? Please, I really need help about this. Thanks |

Please, I really need help about this. Thanks It sounds to me like the computer that's separate has a different kind of network card that is less forgiving of a marginal long cable. Either that, or perhaps in your tests you accidentally used an "uplink" port on the switch in the case that didn't work. What, if anything, do the status lights on the switch and the three computers tell you when the connection is failing? Is the long cable known to be of good quality? You didn't make it yourself, did you? (If you did, I bet you didn't honor the required pairings when you attached the connectors.) -- The e-mail address in our reply-to line is reversed in an attempt to minimize spam.

Our true address is of the form . . First of all, thanks for your interest in solving my problem. Now, let's see: 1. What is "uplink" port on the switch? Does it matters which port I use? Should I not change the ports for each computer I connect during my tests? 2. The status light on the switch are okay; they show three connected cards-computers-cables; the card on the separated computer has 3 lights: 10M-on, 100M-off and ACT- off, which should be on, I think if the network is okay. 3. I can't figured out how the long cable work fine in one way and don't work in other way (which I described in my first post). And yes, I did make it myself, just like other two (the short one's). I think I honor the required pairings (for the straight-thru cables, wright?), just I didn't follow exact color of wires. |
