I have a RTL8723BE wifi chipset which frequently disconnects on my ubuntu 14.04. I have searched a lot of forums to get the solution, but I havent been able to find a working solution yet. I found on the website https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1320070 that has a custom kernel, but that link is no longer active. Is there a solution for this?
There is a new version of this driver at GitHub. You will need to have the package with the kernel headers installed. git clone http://github.com/lwfinger/rtlwifi_new.git cd rtlwifi_new make sudo make install This version of the driver will be submitted for inclusion in kernel 3.18. I ran it for 39 hours with no disconnects.
I may not be experiencing the same bug, but lwfinger's rtlwifi_new package doesn't seem to fix the problem entirely, only partially. I can now go several hours without the connection requiring a reset, but occasionally the connection will stop working despite NetworkManager etc still reporting the interface as associated. I've also added the 'fwlps=0' and 'ips=0' options to the module opts, with marginal improvement.

However I could resolve this issue by performing above steps. Wondering why this issue still exist in latest version of kernel. I am using Ubuntu 14.04 64 bit os, laptop moderl lenovo z50-70
With Ubuntu, who knows. After wasting many hours trying to get out-of-kernel drivers to build after Ubuntu backported API changes, I have stopped supporting any Ubuntu kernels!! My guess is that you did not have the firmware installed. Kernel 4.0 should be OK.
I have the problem of loosing connection on my Lenovo M30-70, I am using Kernel 3.19.0-17-generic on Ubuntu 15.04. I installed this rtlwifi_new driver (comment 1) and the connection is much better, but it still disconnect after a while. It always happens when dmesg shows the following line: wlan0: AP 14:65:11:d7:9f:b6 changed bandwidth, new config is 2452 MHz, width 1 (2452/0 MHz) The only thing that helps is to reconnect manually. Is there any solution for this? (I came from https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1320070 my last comment was that this solution works stable, but now I realized this problem)
Same issue on the same chipset (Lenovo E555) with kernel 4.0 (using wireless-regdb 2014.11.18-1, case it would be related to bug #70881)
I have the same issue with kernel 4.4, on a HP Stream 11. For me fwlps=0 in the modprobe configuration seems to resolve the issue of frequent disconnects. It does not solve the issue of the wi-fi being completely unusable somtimes after waking from sleep (cannot see any networks).
