Question [Q] hotspot and 3g/4g conflict

Hey guys.

Recently I came to find that my HTC One can't use its hotspot capability and it's own internet at the same time.
What I mean is that if i am using my internet and I turn on the hotspot for someone to use, I cannot use it at the same time. I always try it using google.com and it says that "the user is offline" and tells me to check my connections.

I have tried it in revolution hd stock kernel; stock rom and kernel, Stock rom costum kernel, 4.3 and 4.4... And The result is always the same.

I would like to know if someone had the same problem and found a fix. (I am on unlocked bootloader, rooted and S-off, if it helps)

Thanks ahead for the help
