Using Wireshark for a DSL "link no surf" problem

[Kok-Yong Tan <ktan () realityartisans com>]

Is it possible to use Wireshark to troubleshoot a DSL "link no surf" problem?  The ISP insists it's a CPE issue but the 
problem only started after their Tier 1 tech monkeyed with the DSLAM and/or the CPE (remotely) in some manner.  I find 
it suspicious that the problem was intermittent packet loss until they tinkered, whereupon the problem became a "link 
no surf" issue (i.e., there's Layer 2 connectivity but zero Layer 3 traffic passing).
