Well, it's known that ocasionally an empeg network port will not connect with certain hubs. It's not known why, and not all empegs exhibit the problem with the same hub. Usually when the imcompatibility arises, there is no link at all, and adding a different hub inbeween will solve the problem. Some hubs can have problems switching between 10 and 100Mbps ports, so if you can force everything down to 10Mbps that might help, but I wouldn't expect it to solve the problem. Usually I'd just tell you to replace that Linksys switch, but you don't have one...
