Hi, Previously our AEBS was at the furthest end of the house and I'd experience some kind of WiFi drop out. The WiFi icon on the menu at the top of the screen would still show four bars of strength, but if I opened AirPort utility it would show I'm disconnected from the internet (the globe) and a warning symbol next to the AEBS, stating that it was previously a part of the network. We moved the AEBS to a better location which is literally in the room next to me, however I just noticed it happen again now after a couple of weeks. We have the 4th Gen AEBS, handling DHCP & NAT, and I have the base 2011 21.5 inch iMac. Has anyone else experienced anything like this?
