WireLess card keeps dropping

[elidd1]

I am consistantly having a problem where i connect to a wifi network and have full bars 70%-100% signal strength.. I get internet for a little bit, but then it just drops, and my network connection says its still connected.. If i boot the same machine to windows, i don't have this problem so i think it must be some kind of driver issue..

here is the output of my lspci :

I tried installing firmware-b43-lpphy-installer as someone suggested in another forum but got an error:

I assume that it is not the right driver.. can anyone help?

i'm not expert but i THINK you need (maybe)a realtek driver (("Realtek Semiconductor Co., Ltd."), device: b723 ("RTL8723BE PCIe Wireless Network Adapter")) && check if it's supported by kernel

[gentrix]

I think you first need to check if the chipset is compatible with the kernel; use http://www.cyberciti.biz/faq/linux-f...river-chipset/ to see your chipset informations,
oh and kali 2.0 still has a bug with displaying the current connections so you shouldn't rely on that much. but check if it is compatible if it was then download the latest driver for it and it should work just fine
