Hi all,
I am very new to Linux and facing similar issue with RTL8723BE on HP-

At first, the system couldn't recognize any Wifi network.
Tried the rtlwifi_new. Now, the wifi does connect, but only withing a
range of 1M from router's antenna. The connection drops are very
frequent.

I have a ThinkPad Edge e540, same problems with 13.10 using the driver from gh.
Reloading the module works, but not for long.
Seems like a lot of newer Lenovo laptops have this wireless adapter, I couldn't
order mine with a different one in my country.

Could somebody backport the driver to Trusty please?

https://github.com/lwfinger/rtl8723be - works for B5400. However, it is
necessary to manually declare few constants in the code:
#define IEEE80211_CHAN_NO_IR0
#define REGULATORY_CUSTOM_REG 0
#define REGULATORY_STRICT_REG 0
#define REGULATORY_DISABLE_BEACON_HINTS 0
This device is on Lenovo B5400 too. No support yet in 13.10 and 14.04.

I couldn't find the edit option for my comment, so here is a solution for lost
Internet connection problem:
sudo modprobe -r rtl8723be

This helped me and now I don't have to reboot the machine after Internet
drops.
