I don't agree. I have seen more problems generated by incompetence in trying to fix duplex/speed, than I have seen problems generated by autoneg not working properly. I am always amazed by the fact that very few people out there know that you have to lock duplex at BOTH ENDS of any given link for it to work properly. Generally, in a LAN environment with good quality switches and good network cards, autoneg works just fine. Yes, with 10/100 meg fiber/converters converters you should definately lock duplex, but in most other cases I recommend to leave the duplex setting to auto. Yes, cisco routers are notoriously bad at doing autoneg, but I blame that on cisco and not on autoneg. The el cheapo $50 desktop switches seem to hack autoneg just fine. -- Mikael Abrahamsson email: swmike@swm.pp.se
