I know this is nitpicking, but, by "coax" I assume you mean "thin ethernet", "thin-net", whatever. Thick coax worked just fine for me, much better than 10baseT when it first came out, or trying to use 10baseT on older wiring. A clean thick ethernet coax installation was no problem - except that it is expensive/time-consuming to install, and, worse, to modify. However, 10baseT became very reliable about four years ago, and, on a good cat-5 installation, is very nice, as everyone knows. I agree that thin-net should be avoided like the plague. I never had anything but trouble with it, even for short distances. I was surprised to see it still being promoted for cheap home/small-office installations, as I observed in an electronics store a few nights ago. Especially now that you can get inexpensive, small 10baseT hubs (but only for about the last year or so has the price really come down) from several vendors. Today, there is absolutely no reason to use anything other than 10baseT (or 100baseT) on new installations. Always use level-5 wiring. [And, I would recommend eliminating *all* the thin-net coax from existing installations.] To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isp" in the body of the message
