If they only work at 10Mb, then the SB will happily use them. The SB will use the highest rate it can negotiate. -- Michaelwagner Michaelwagner's Profile: http://forums.slimdevices.com/member.php?userid=428 View this thread: http://forums.slimdevices.com/showthread.php?t=16981 ___ discuss mailing list discuss@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/discuss
[slim] Re: Limiting Ethernet speed to 10 Mbps
Hmn... Seems that negotiation happens based on what the endpoints want, not what the wire can handle. So if one wants 100M and the other 10M, then the 100M node will negotiate down to 10M. If both endpoints want 100M but the line can only handle 10M, then the endpoints have a very hard time figuring that out. In my experience, they don't figure it out... :p So the only solution I can figure is to be able to force one end or the other down to 10M, which will force the other to follow. Since the SB is already highly programmable, it seems to be the easiest place to add this functionality... -- winstan winstan's Profile: http://forums.slimdevices.com/member.php?userid=6272 View this thread: http://forums.slimdevices.com/showthread.php?t=16981 ___ discuss mailing list discuss@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/discuss

Here's another reason why being able to switch a SB3 to 10Mbit would be really nice: What if I'm using a couple of these http://www.etslan.com/Ethernet.htm and the RG6 run to my living room? These baluns confuse the negotiation process, and they definitely only work at 10M.

That goes all the way from the front office to the back of my factory just fine. It's actually 100 meters between switches or hubs, but only 2 hubs maximum for any path traversal. So check if you have only hubs in your house and count how many your signal is going through. The limits are more relaxed for 10baseT, I think 4 or 5 hubs, so if 10 works and 100 doesn't, check how many hubs you're sending your signal through. If it's more than 2, replace the central one with a switch if possible. That's a better solution than putting up with 10baseT (or replacing wire already in the wall). Is the wire in the wall CAT5?

That, or it's damaged or badly installed - kinked, crimped, stapled through, or maybe running parallel to electrical wiring or over fixtures. None of which answers the original question - Can the Squeezebox2's 10/100 ethernet port be fixed at 10mpbs? You could accomplish this by controlling the switch port's speed, but most SOHO switches are unmanaged and have no such control. Over the years I've solved numerous ethernet incompatibilities by fixing a port's speed. Usually, though, it's to fix problems with the auto-speed-negotiation, which sometimes doesn't work as it should. -- JJZolx Jim ___ Discuss mailing list Discuss@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/discuss

Pat Farrell wrote: All ethernet wiring (well at least 99.99%) has four pairs of wires internal to the cable, and you only need two pairs. So if only one or two wires are bad, you can just reterminate it and save dragging wires. Don't ignore this suggestion (providing of course you have checked that both ends are terminated correctly)! If it is only some fluky damage to one wire; using a different pair would be an easy fix. You might also want to check the condition of the spring wires inside the receptacles. Ensuring they are in the right slots and teasing them down for a little more tension (or replacing the receptacle altogether) could be a good idea if it looks suspect in there. Reseating and/or recrimping is also another idea, providing there there is enough wire in there to bite. P.S.

With hardware I have to know what 568B means and how it is different from 568A :) Nah, you just have to be consistent. The signals don't know what color the wire is. You can invent your own scheme as long as you do both ends. Might make a difference at way high speeds, and really long distances, but most of the time it isn't important. The signals don't care what color the wire is, and most devices these days don't even care about polarity, but they definitely care that each signal is twisted with the right partner. Ethernet depends on differential signalling to reject noise and crosstalk. You need to pair 12, 36, 45, 78. If they're not paired right, you can't count on it working even at 10Mbps and even with short cables - I've seen it fail many a time when someone used a RJ45 phone cord (CAT5, but paired differently) in place of an ethernet cord. (actually 10/100 only uses pairs 12 and 36) -- seanadams ___ Discuss mailing list Discuss@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/discuss

Some anecdotal experience on the 100m rule: I recently ran a 90m cat6 line. Needed to get from suite 900 in our building to suite 400. However the conduit all goes to suite 100 (they're all in a row), so it had to go there and back again for a total of about 90m. I had hoped that the link would work at gigabit speed (which is supposed to work over CAT5e at 100m). Come to find after installing it, the switches would only negotiate 100Mbps. After replacing the short cat5e patch cords going from the patch panel to the switch on each end with cat6 patch cords, the link came up at 1000 Mbps.
