WiFi Bluetooth shaded black

I'm seeking help with my WiFi and Bluetooth shaded black. I know the are tons of threads on this issue. But I've been at this for about a year. I've come across many solutions. But the issue seem to keep resurfacing after every solution. I get at a point in which after using triangle away I can get it to shade grey and turn on for about 10-20 mins but after that it shades black not grey and refuses to work. This is slightly different then any other solution as this can be repeated and it keep working then it stops. I've spent countless hours and many frustrations at repeated partial solutions which leads to inevitable failure. I'm rooted and Knox is tripped. The solution has to fall into I would assume the bootloader were the Knox trigger is. As some on xda might see I'm a noob but have been with a very limited scope mainly my device kinda know what I'm talking about. I'm at a total loss. I've ventured in to my system with various tweaks to no avail and can't change my bootloader/modem due to what I assume is knox. I have no idea where to go from here. I wouldn't expect anyone on here to give me a solution to this problem though it would be nice. However a point in the right direction would be greatly appreciated. If anyone knows anything please respond. I couldn't tell you all the relevant information I've collected and things I know pertaining to this but ask if I've tried and I could tell you.

Please and thank you in advanced
