I have same issue. But when i change my wifi router security setting ( WPA Encryption: AES to AKIP or AKIP+AES) then if works fine.
I tried that but it didn't help fixing the connection issues for me. However, i have changed my router from WPA to WPA2 and now i am able to connect WiFi (WNDR3700 using OpenWRT).
FM Radio is weird. It seems that libandroid_runtime.so does not export the required functions
-> java.lang.UnsatisfiedLinkError: Native method not found: android.hardware.fmradio.FmReceiverJNI.acquireFdNative
I read somewhere that Verizon M7 does not have FM Radio maybe this is the base for this ROM? I checked libandroid_runtime.so on my HTC One Mini 2 and this one exports these functions. However, trying to use this library on the One S and the device does not boot anymore.
