wlan0: deauthenticating by local choice (Reason: 3=DEAUTH_LEAVING) ->Wireless Network controller [0280]: Realtek Semiconductor Co., Ltd. RTL8723BE PCIe Wireless Network Adapter [10ec:b723] - wireless connection unstable on Lenovo G40-70 20369 (based on LENOVO Lancer 4A2) in Ubuntu 14.10

Wireless connection keeps dropping:

Hi, I've currently bought a Lenovo g40 laptop. I've installed ubuntu 14.10 lts. I've tried to troubleshoot my wifi disabling iwlwifi 'n' , also change the config of my router from WPA AES to WPA2 AES. I've also updated my kernel to version 3.19. It did not fix my wifi connection. The wifi access point I was connecting to was 'TP-JAIRAHMHAT'.

Here is my wireless adapter details:
