Ideapad A1-07 tablet wifi-bluet​ooth does not work!

Hello everyone. As you can see from the title on my tablet is not working wifi and bluetooth. When turning wifi tablet is reset and continues to be off and on until it forcibly turns off, and when you turn it on again, and do not touch wifi everything is normal and there are no problems with resetting. Can someone help me and give suggestion to solve this stupid problem.  I'm from Croatia and I'm bad with the English writing.
