Responsible Changed From-To: gnats-admin->freebsd-bugs Refile. State Changed From-To: open->feedback Does this problem still occur in more recent releases? Responsible Changed From-To: freebsd-bugs->danny This sounds related to danny's change in rlphy.c rev 1.6. Justin, please apply those changes to your system to see if they resolve the problem. State Changed From-To: feedback->closed 10 Mbps autoneg fixed with: 1.6 +3 -18 src/sys/dev/mii/rlphy.c 1.2.2.2 +3 -18 src/sys/dev/mii/rlphy.c |
On 10mbit LAN's, (many) NIC's which use the rl0 driver (a discussion has been had recently on freebsd-questions as to who and which cards have given problems) appear to fail to correctly autoselect 10mbit and attempt to use 100mbit, causing slow data rates and potentially problems for the network. Fix: ifconfig can be used to force the card to 10mbit mode ("ifconfig rl0 media 10baseT/UTP"), which then solves the problem. This obviously has to be done on every reboot. Obviously this problem is ideally fixed in the driver (If that is the source of the problem), as these cards appear to operate perfectly in other operating systems (Windows, Linux, etc). How-To-Repeat: Boot a machine with a Realtek based ethernet NIC on a 10mbit LAN.
