Hello,

I'm now running Linux 3.0.8 and I still see this issue:

$ ifconfig eth0

eth0 Link encap:Ethernet HWaddr f4:6d:04:39:XX:XX

I'm not absolutely certain about the quality of equipment I'm connected to - so I'd like to know how can I
remove it out of equation.

My Internet connection seemingly works this way:

My_PC -> 16-port unmanageable Ethernet switch -> Cisco Ethernet switch -> Cisco PPPoE concentrator (the
first device I can ping via PPPoE connection)

Best wishes,

Artem
