Samsung Galaxy S4 WIFI & Bluetooth won't turn on

[gansat]

My Samsung Galaxy S4 (SGH-i337) wifi is not turning on for the last few days. I've tried all options that's available in various other forums including master reset, wipe cache partition, renaming the wpa_suppliant.conf as well as rooting the OS and installed NJ4 kernel software. Nothing has helped to get back the wifi. Are there any other suggestions that could help me? Thanks in advance for your help & suggestions.

This has happened to me on several occasions. No rhyme or reason. Just comes back on.
