Help. My iPad Air (running iOS 7.0.4) suddenly can no longer connect to my Netgear N600 (WNDR3400v3) router on the 2.4 GHz channel. What I find interesting is that the iPad Air still connects on the 5 GHz channel, my Windows 7-based laptop also connects fine with the 2.4 GHz channel, and even my Samsung Galaxy S III connects fine with the 2.4 GHz channel. Any suggestions on how to fix this problem? Do I need to change the channel configuration of my router on the 2.4 GHz side to see if I can remove a potential conflict with other routers in my neighborhood nearby?
