Re: Using Wireshark for a DSL "link no surf" problem

[Pedro Tumusok <pedro.tumusok () gmail com>]

Well if the tech can see stuff, its not what I thought might be the
problem, which was PVC settings.

But does your modem get an IP address, ie is it setup as a router or does
your computer get the ip address?
Are you using PPPoA/PPPoE etc?
