I was prompted to update firmware version from v104_b1 on 10-29-2014 to the latest version via the Dlink app on my Iphone, before i did this i connected an ethernet cable as recommended and proceeded with the update, after the camera rebooted everything seemed fine so i disconnected the ethernet cable and the red light stayed lit. I rebooted the camera several times (also rebooted router Asus RT n66u) hoping that would fix the problem. I reconnected the ethernet to gain access to the settings page and reconfigured the wireless settings but after rebooting again, still no wireless connection, after fooling with the camera for an hour i had to back up the firmware to the previous version. Once this was accomplished the wireless connected immediately. I believe there is a flaw in this upgrade, the IOS app still prompts me to upgrade but until this is resolved at Dlink i will ignore it. I'm happy this camera will let you revert to a previous version.
