Wow, they just cut and paste that (with no added commentary) from Tampa Bay Online -- and while they give credit at the end ("Source: TBO"), they don't give a link or nothing else. Here's the original article: http://www2.hernandotoday.com/content/2009/feb/28/ha-dial-up...
thanks for posting the link, I tried to find the original post which netted that link, but the hernandotoday threw me as someone's personal blog so I never bothered to open it
RJ11 is for phone, RJ45 is ethernet. Connecting the telephone system to an Ethernet jack can supposedly break the phone system or short it out or something. You can often plug RJ11 into an RJ45 jack, it will fit and make some contacts, which is often done to save on in-wall wiring costs in mixed networking deployments where you're still using POTS and not VOIP.
My philosophy professor still uses dial-up. He says it's because wireless is so unreliable My head almost exploded when he said it because he was using his laptop on our school wide wireless internet while he was saying it.
