[-- Attachment #1 --] The Netflex (Thunderlan) embedded ethernet controller in the Compaq 1850R does not seem to like the Thunderlan driver. When connected to a 10BaseT/UTP hub the controller will continuously cycle through the auto-detection bringing the connection (and the physical link) up and down repeatedly (driver with no arguments - default of autodetect). The same configuration will work fine and detect 100BaseT full duplex when connected to a 10/100 switch and the network connection functions. I have tried adding the 'media 10BaseT/UTP' argument which causes the controller to lock into that mode without autodetecting, leaving the link established. However, no data will pass (cannot ping in our out). I can ping the loopback address and I can ping the local IP. I have reproduced this problems with multiple versions of FreeBSD (2.x,3.x,4.x). My assumption is that Compaq has implemented the TI Thunderlan chipset in a "nonstandard" way and thereby broken the driver. Has anyone else seen/solved this problem? Any help/suggestions would be appreciated. Michael S.
