[Newbee on Kali] Wifi Disconnects and Reconnects

Well I'm not new to Linux, I've gone through Ubuntu and mint, Gentoo, etc. So I wanted to try Kali Linux so I can practice and master my information security Hobby. I tried it first on a live with persistence, and everything worked fine, so I installed it on my hard drive, and everythings goes as in the live version, except for one important detail..

Right after booting, the wifi works fine, and it loads around the first 3 or 4 webpages on firefox, but right after that, it doesn't load the pages anymore, and the wifi starts going down and reconnecting constantly, and sometimes if I restart the network-manager service it works again for the next 5 minutes.. and it starts failing again.. I've tried a couple of other posts and forums and all their solutions, but nothing seems to work, the only thing I couldn't try is the NAT thing on the network configuration, because I can't actually find it in the settings (I'm using Gnome and it seems like the settings application is far more simple than the rest)..

Could anyone help me please, or at least tell me what you think the problem may be, or even how to get to more advanced settings in the gnome enviroment..

Here are the logs when I run dmseg regarding the connection (I'm connecting through wifi):
