When you say you cannot even ping, does this include internally on the network (i.e. ping the router, or another device connected, such as a desktop or laptop), or are you only trying to ping out through the modem?

As with the Linux box, do you have mii-diag installed - what output does it give? For example, I get:

jonathan on jonathan [ ~ ] --> sudo mii-diag
Using the default interface 'eth0'.
Basic registers of MII PHY #0: (snip)
 The autonegotiated capability is 01e0.
The autonegotiated media type is 100baseTx-FD.
 Basic mode control register 0x1140: Auto-negotiation enabled.
 You have link beat, and everything is working OK.
 Your link partner advertised 45e1: Flow-control 100baseTx-FD 100baseTx 10baseT-FD 10baseT, w/ 802.3X flow control.
   End of basic transceiver information.

when connected, and 

jonathan on jonathan [ ~ ] --> sudo mii-diag   
Using the default interface 'eth0'.
Basic registers of MII PHY #0:  1140 7909 02a8 0390 0de1 0000 0004 2801.
 Basic mode control register 0x1140: Auto-negotiation enabled.
 Basic mode status register 0x7909 ... 7909.
   Link status: not established.
   End of basic transceiver information.

disconnected. What messages are in dmesg?
