Networking Woes (done this before)

ipodandimac

Ok I've done my fair share of networking, and had this exact setup working at school yesterday.



I have a cable modem plugged into an Airport Extreme, the airport extreme configured for DHCP, and then an ethernet cable going to an eMac, with the eMac configured for DHCP as well. The AE is set to distribute IP addresses using 10.0.1.1, and my powerbook is connected fine (right now). The eMac, though, keeps generating a bogus IP address using DHCP instead of 10.0.1.2 for example. I have no idea why it's doing this, and I've restarted every thing in the chain of networking. I wouldn't be so mad if no internet was working, but for it to be working right on my powerbook but not the eMac doesn't make sense. Suggestions?

Hi



I have seen the exact same problems laterly.



I have been able to get thing to work again by doing the following which may or may not work in your case.



I went to system prefs/Networking/Airport and manually turned it off via there and applied it. Then tuned it back on and renewed the lease and applied.



This has worked several times for me now.



On the odd occassion it doesn't I turn off both the cable modem and Airport Express and once they are ready everything is then working.



These problems have been around but quite as bad since 10.4.2 but where made much worse since the Airport update 2005-001.



I hope this is of some help

I would try setting the IP address manually at both ends and see if it works that way.



If it does, then I would turn the DHCP back on at both ends and force the Mac to renew the IP.

BTW, what OSX version are you running?

thanks for the replies. i guess the eMac and its 800Mhz of horsepower just took a while getting the airports dhcp stuff. i left it on for a couple hours and it worked itself out.
