I think it would be worthwhile to swap out the DSL modem you are
currently using with a different one known to work correctly. Since you
previously swapped your hub for a switch and had the same problems this
suggests the fault is toward the WAN side of your LAN. Your service provider
reports that everything is fine as they can see it so the next component to
suspect is that DSL modem.
DSLExtreme might let you borrow one (perhaps of a different manufacturer than
than the one you are presently using) for troubleshooting purposes. Or you
might borrow one from a friend or neighbor. (There are lots of DSL modems
floating around because providers often give them away to new subscribers
whether the subscriber needs one or not. And people frequently leave them
behind as they move out of apartments or houses.)
Also, IIRC you said the cable (phone wires) checked out OK by DSL Extreme. The
DSL modem is the active electronics component between your LAN and the DSLAM
at the DSL Extreme office or telephone company central office. 
I don't have one of these DSL modems to offer you for testing purposes.
Good luck, I know these things can be exasperating.
 The DSLAM, or Digital Subscriber Loop Access Multiplexer, is typically
made by someone like Alcatel or Cisco, and placed in the telco's Central
Office, or sometimes a suitable remote location. The DSLAM is also active
electronics equipment and connects to the DSL modem using passive copper
