    I fixed the speed of both Mac and PC to 100Mbps full -  Reset AE, power cycle Switch, then added mac - speed 75Mbps. Added PC, both at 75Mbps. All is wel!. PC goes to sleep, wakes up back to 9Mbps on both.  Both show link speed of 100 (fixed).

    Question: how to a find the link speed of the Airport Extreme?  Switch only has green LED so no clues there.



    I also had a problem with both Mac and PC (different time) where they said cable disconnected. PC would connect until operating system up, then switch LED would go off and PC would report cable unplugged. Simular for Mac.  I have seen other post with same problem.

    The fix is to power off all systems and start again - all the other fixes suggest, change config etc  in effect restart the router. I changed switches and cables with no effect.

    Hence I think that the issue is the auto negotiation of the AE and re-start all system restart/refresh the auto negotiation. fixing the end client help.



    it used to work ok, so what has changed. AE firmware?


    Solution for me:

    Use WiFI may only give 40MBps but it is better than 9Mbps !!!
