Frequent Lags and Disconnects With DSL

Hey guys. At our house we have Fast Access DSL through ATT. We are getting very frequent disconnects and lags. We have multiple devices running off of a single DSL modem/router. It has wireless and wired connections available. Our wireless devices disconnect as frequent as our wired devices do. We have called ATT many times. They have had us replace the DSL filters and did a line test outside our house which came back clear. However, when they run a line test while I am on the phone with them, they say they detect multiple errors on the line. We have replaced our DSL modem with a new one as well. It is a NETGEAR VersaLink Four Port Ethernet Wireless Gateway, Software VER:06.04.12. The self-diagnostics on the Modem come back clean with no problems detected. We get static on our phone line frequently as well.

Here is a screenshot of my modem's statistics page. Any help would be much appreciated.

In the technician readout part of my modem I also see this if it helps:

So the NID [in most cases grey phone box on the side of your house near power meter] has a test port, you can buy a LONG jumper run it to your modem and test it, if it stops going off line you have a n issue with your inside wiring, it may NOT be the line the modem is on , it may be another line another phone is on, the test port will require you disconnect the house wiring to use. If this fixes the issue [temporarily] either rewire your house phone, or have someone trouble shoot YOUR wires. Usually someone left pig tails on the outlet or screws in the NID and they are shorting out either on an unused pair or possible the primary pair. Sometimes there is corrosion where water got in, or a wire is damaged physically as well, and less commonly, a splice is loose, but it happens. Also alarm feedback can occur if their components are old and you have one even if its not active.

Thank you so much for the help, Waca. I will try out your troubleshooting tips and post back with the results. I figured it was probably something physical with the wire, but I didn't know if any of my router statistics would indicate exactly what it was.
