SylvesterCorsayou have to pay to switchjp_Switched to different lines that didn't have any corrosion. Problem with flaky connection went away.How'd you switch?
???
That's only if you need AT&T to come over and wire things in the house for you.
There were multiple phone lines (practically one in each room) inside the house that went into a junction box (in the garage) leading outside. I removed the plastic cover from the phonejacks and looked for wires without corrosion. I found one with 2 lines (4 wires), corroded line and an unused line. I connected it to the jack and changed the connections in the junction box in the garage.
Instead of doing all that first, you should just open the plastic cover to the RJ-11 jack that your modem connects to and inspect from that end. Also if you have different filters, you should try them. I had more success with different ones.
Also give a call to AT&T? I had a good time calling up their techs to dig my neighbor's yard.
