I just installed Red Hat Linux 9.2 on Dell Latitude D500, but no network card was detected. When i ran lspci command i saw these in the ethernet controller row:

02:00.0 Ethernet controller: Broadcom Corporation: Unknown device 170c (rev 02)

Can someone please help me out? I need to access the internet with it.

I have found a (possible) bug in Ethernet driver provided by most Linux
distributions. The symptom of the bug is:
When a user runs Windows and then restarts (soft reboot) in Linux the
Ethernet card stops working.
Solution: poweroff and then start the computer. Avoid soft reboot from
windows to linux.
The problem was found on connecting ADSL broadband and cable-net. It was
tested under SuSE 10.0 (32 bit) and Fedora core 5 (x86-64).
Readers, please try this and inform others about the bug. Suggest me where I
can report this (possible) bug. Thank you.
