losing phone jacks here, one at a time. the Internets were offline earlier until I tried plugging the DSL interface (no, I won’t call it a modem since it doesn’t do what modems do) into a phone jack in another room. It stayed online, so now I have a snake of Cat5 cable running through a couple of rooms to get everything working again.
Lost the phone jack in the bedroom ages ago, but didn’t care all that much. Now I think it may be time to call in some professionals. The spaghetti-tangle/spider-web I can see looks too messy for my rusty telco skillz. I don’t even have a set of punch tools anymore.
So if your DSL connectivity gets squirrelly, that’s one diagnostic step you can try.
