But shouldn't the Squeezebox auto-negotiate the connection down to 10Mbps if 100Mpbs fails?

If you're not following one of the standards, that's probably the most common way to incorrectly wire the jacks or plugs. If 10Mbps is working, but 100Mbps is not, there could be a host of problems - too tight of a radius in a cable bend, running the cable parallel to electrical wiring, running too near fluorescent light fixtures, nailing or stapling through the cable. I've posted this before, but here's my little spiel on running cabling: For a long, permanent run of Cat5/5e/6, use solid core cabling, not stranded core. Terminate both ends of the cable with _jacks_, not plugs. Then use patch cables at either end betwen the jack and the equipment - in this case the SB at one and the router/switch at the other. Do NOT make patch cables yourself with plugs and a crimper - they're far harder to make correctly than you'd imagine, and preassembled patch cables are both inexpensive and available in many lengths. Solid core cabling, jacks, jack housings (or wall plates) are commonly available at places like Home Depot. Depending on the type of jack you buy, you may need an inexpensive punch down tool, or you can get by using a knife. Often the tool is packaged with the jack itself. The jacks are usually color coded with both 568A and 568B wiring patterns - just choose one and stick to it on all jacks that you wire. As far as running the cable... Don't kink the cable. Don't crimp it excessively with staples, tacks or other fasteners. Avoid sharp bends wherever you have to go around a corner. Avoid running data cabling near electrical cabling, but if you need to cross an electrical cable, do so at a 90 degree angle. Keep data cabling away from flourescent lighting fixtures. Untwist the colored wire pairs for no more than an inch or so from where they're punched down in the jacks. -- JJZolx Jim ------------------------------------------------------------------------ JJZolx's Profile: http://forums.slimdevices.com/member.php?userid=10 View this thread: http://forums.slimdevices.com/showthread.php?t=24689 _______________________________________________ discuss mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/discuss
