Woke up this morning and had no internet. Unplugged both my cable modem and extreme, replugged and still nothing. Did a reset on my extreme with a paper clip. That seemed to do the trick for about 5 minutes before I lost connection again. I then reset again using the paper clip and tried to setup in Airport Utility. Kept getting "unexpected error" message repeatedly. Nothing I did seemed to work. Oh well I thought, maybe it's time for a new one. Check my wires and they seem to be fine. I can get internet straight from cable modem to iMac no problems. When I try to connect hard wire from extreme and modem to iMac, I can't get no connections. Went out and bought the new tower extreme and I'm still having issues. I can get wifi throughout the house but no ethernet connection to my iMac in my office. When I was able to get a connection from extreme to iMac, I lost my wifi. What the heck am I doing wrong? Help?? I've spent at least 3 hours now trying to figure this out.
