100Mbit Ethernet Notes

By: Richard Glaser - Revised: 2006-06-07 devin

Most if not all of this is unconfirmed...
  1. Apple's Zynx card (aka Apple 10/100) 100Mbit card has been reported (but not confirmed) to not work at Full Duplex, but will report that it can. This can result in terrible performance. Force your switch/hub to half duplex for any computer that is using this card.
  2. Several people have reported that Cisco Switches work much better if you turn off spanning trees which is on by default.
  3. Unconfirmed from Asante
  4. Three extensions seem to interfere with the connection on the b/w g3s but not necessarily other g3s or g4s, although the folks at Asante suggested I scrub them on all machines. They are: DNSplugin, SLPplugin & WebSharing.
  5. If you have an aftermarket ethernet card, you should also disable the Apple Enet extension.
  6. If you are using Asante cards, be absolutely sure you have the latest driver.
  7. Another unconfirmed report. Try moving your ethernet card to a different PCI slot like A1. Apparantly some customers have reported that this has fixed their problems.
