There may be someone near you on the same channel, causing interference. Although there may be 11 channels for use where you are, there's overlap, and it boils down to using one of the end ones, or one in the middle (yeah, three usable channels out of eleven). Over the years, I've had to replace modems, switches, and ethernet cards, because they've *all* failed at times. It seems worse with anything with a long cable attached. If there's thunderstorms even remotely nearby, they can induce destructive currents into the cabling. If you cable between buildings, there can be a significant difference in earthing between them, and you can put a lot of current through something that joins them together (you need ethernet equipment that's galvanically isolated, and many cheapies don't bother with using transformers on the ethernet lines). Anything connected to the phone system has /that/ length of cable between them and the exchange to expose them to destructive interference. While some people advocate using surge arrestors, I'll point out that they don't prevent your equipment from being destroyed, they just try to limit the damage so that (hopefully) your house doesn't catch fire, too. And, of course, there's the case of random electrical component failure. -- tim@localhost ~]$ uname -rsvp Linux 3.19.8-100.fc20.i686 #1 SMP Tue May 12 17:42:35 UTC 2015 i686 All mail to my mailbox is automatically deleted, there is no point trying to privately email me, I will only read messages posted to the public lists.
