It's been about a week now since i switched and have observed the nfe0 link down, link up, followed by perpetual timeout scenario. During this same period the weather around here has started to feel like it's mid-summer with temperatures easily reaching the upper 20s to lower 30s. We share our internet-connection here with about 6 appartments and as it turns out over the last couple of days i have not been the only person who has had some oddball network events happen to him. As it turns out some people have had problems where they simply wouldn't get a link until after they pulled the cable and plugged it back in again, and since about 2 hours ago the power supply of our Gb-switch seems to have become of the persuasion it wants to become a space-heater instead. Initially the Switch's Power LED would still turn green though no link LEDs would light up (and no links were established) and about 15 minutes after that the power LED also no longer turns on. This could very well explain the spurious link losses i've been observing. So i'll likely be getting us a new switch tomorrow (currently have the whole thing running through an old 10-baseT HUB) and keep an eye on things to see how they will develop from there on out. If the nfe problems persist, i'll definitely try the provided suggestions but for now i'll put the investigations on hold. With kind regards, Pascal Hofstee
