I have some network issues with my T60p (Model 8742-C3G).
The (lan) network traffic stucks sometimes, especially if I enable the wireless
kill-switch. The network is 100MBit FDX and I've tested different peers.

An example 
with kill-switch off:

Same machine in Windows and I have always max 1 ms. 
I've tested another machine on the same LAN cable and it shows max 1.2 ms.
Wireless on this machine works without problems.
