Dear Bruce et al., I did try using a different computer (PM G4 MDD 2003) with the same Ethernet cable and DSL modem. It worked perfectly (as it had in the past). Then plugged the G5 in again and decided to jiggle the cable around. Sure enough, when the plug is pulled outward (but still seated) it disconnects.When pushed inward as far as possible there is no problem. I tried the same maneuver with the second Ethernet port and had similar results (second port slightly better). Also tried a different cable; same story. Whew! It would seem that my options now are: 1. Open the machine and check the connections at the Ethernet ports for any repairable looseness (doubtful). 2. Use Ethernet and tape the cable securely in place. 3. Install wireless capablility, which I intend to do anyway, and forget about Ethernet. 4. Get a new logic board (doesn't seem worth it). Any further comments welcome, and many thanks for all the help.

Might be a bad batch of plugs. Something in the mold when they were made. I would try a different brand of cable / batch of plugs. Other thought. The actual contact wires inside the port might be compressed too much and not making contact. On port 1 (the worse of the 2) I would take a bent paperclip and VERY GENTLY try and pull/ bend the internal contacting wires out a little. That should get you good contacts.

Normally the little catches on the plug prevent the cable from having much play, and since you say you can pull the plug outward while connected, this implies there is too much play in the connector, and that perhaps a different cable with a tighter catch would solve your problem? Otherwise, ethernet ports phone ports all used bent wire connections that act like little springs. If one single wire gets bent inward, the port can act like you describe when that wire doesn't quite reach the cable connector. You can often look inside the port and see if any wires look bent? If any are bent, you may be able to straighten them from the outside using an open safety pin as a tool, perhaps with a small J bend at the tip so you can pull the bent wire back to it's normal position. Only attempt this with the Mac SHUTDOWN and DISCONNECTED from power. Safety pins are soft enough to J bend the tiny tip with appropriate tools, but sewing needles and stick-pins are generally too hard and brittle to put any bends in, they snap off. It's a delicate operation that requires good light and magnification IF a wire is bent. If all wires look identical an good, then you may need to open the Mac and see what's going on inside. -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.

Herb Goodfriend Elizabeth, New Jersey It might be helpful if you provided a bit more info about your DSL connection and G5. Does it actually have two physical ports? What brand and model is your DSL modem? Does your DSL connection use PPPoE or DHCP? How long do you have to be inactive before the connection drops? Does your monitor go dark in that time? When you say inactive, do you mean you stop using the G5 or stop using the Internet? You should also check the system log for any errors. Offhand, I'd say that for one reason or another your G5 is having problems waking the Ethernet port after sleep. Have you tried disabling sleep entirely to see if the problem goes away? It's a long shot, but you might also want to try a new Ethernet cable.
