My 2 cents on this dreaded wifi+bt card. My system: Lenovo Flex 2 - intel i5 + 8GB RAM Ubuntu version: 15.04 (clean install)
Previously when I was on 14.04 LTS, I had to create a rtl8723be.conf file and add the options to make my system stable. I did a clean install of UBuntu 15.04 a couple of days back. After which, I am able to connect to the wifi network without any extra setting. I made a few changes to wifi router though (Dlink N router) 1. Set channel to 1 2. Set frequency to 2.4GHZ 3. Set encryption to WPA+AES I have a stable connection, with no drops . I have a few issues though. 1. The wifi never connects when laptop is woken up ffrom sleep. Needs a reboot 2. The wifi never connects to router when signal strength is less than 50% -- 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/1461174 Title: Realtek Wifi card rtl8723be [10ec:b723] WiFi has an issue Status in HWE Next: Triaged Status in linux package in Ubuntu: Confirmed Bug description: My WiFi has an issue. --- ApportVersion: 2.14.1-0ubuntu3.7 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC1: u 1785 F.... pulseaudio /dev/snd/controlC0: u 1785 F.... pulseaudio DistroRelease: Ubuntu 14.04 HibernationDevice: RESUME=UUID=c2a5715c-c92c-47fa-9aa2-c6f6e03f21bf InstallationDate: Installed on 2015-06-09 (0 days ago) InstallationMedia: Ubuntu 14.04.2 LTS "Trusty Tahr" - Release amd64 (20150218.1) MachineType: Hewlett-Packard HP 455 G2 Package: linux (not installed) ProcFB: 0 radeondrmfb ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-3.16.0-30-generic root=UUID=97d2645a-a2be-49ec-b1bd-37c43ab4eeb1 ro quiet splash vt.handoff=7 ProcVersionSignature: Ubuntu 3.16.0-30.40~14.04.1-generic 3.16.7-ckt3 PulseList: Error: command ['pacmd', 'list'] failed with exit code 1: No PulseAudio daemon running, or not running as session daemon.
