im close to pulling my hair out!!!! i updated my AEBS n to the new firmware, and it stopped working completely! just wasnt showing up in airport utility. so i did a hard reset and put it back to 7.4.1. now i am having an intermitent problem with the signal strength... basically ill get full speed sometimes them sometimes it'll go off air, either hang the connection,not load the page at all or completely disappear from my task bar. just wondering if anyone has got this issue, or has any advice to resolve it. thanks as always!!
