Two versions of Ubuntu and this is still a major problem. Running Ubuntu 15.04 (with several upgrades from previous versions) on Lenovo S540 with RTL8723be.

Re: [Kernel-packages] [Bug 1240940] Re: Need support for Realtek Wifi card rtl8723be [10ec:b723]
Hi, I have tried the same as Sergio and have the same result. Latest 3.13.0.31 kernel does not fix it. I also have the options mentioned. The best I managed is with kernel 3.14 and the driver from github, and still from time to time the network stops and asks me for a password. If I enter it, most of the times the network reconnects. I tried with latest 3.15, but I cannot even compile the driver there. I expected that 3.15 would already have the driver in it, but alas...

[Kernel-packages] [Bug 1240940] Re: Need support for Realtek Wifi card rtl8723be [10ec:b723]
Hi, I've had this problem since november 2013 when I bought the laptop. With Ubuntu 13.10 at least modprobe and modprobe -r used to work. With Ubuntu 14.04 the connection drops even more often and only restart helps (most of the times). All drivers I found origin from the released by RealTek. They seem to have a bug which no one still cannot find and fix.

This device is on Lenovo Thinkpad S540. It is not recognised by Ubuntu 13.10 and 14.04. There are some drivers on github but after working some time, the connection drops and I have to restart. Also my dmesg is full of rtl messages. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1240940 Title: Need support for Realtek Wifi card rtl8723be [10ec:b723] Status in HWE Next Project: New Status in HWE Next saucy series: New Status in HWE Next trusty series: New Status in “linux” package in Ubuntu: Confirmed Bug description: This device is appearing in some OEM machines, but driver is not yet available upstream.
