Henk Stubbe, could you please advise to the router manufacturer, model,
firmware version, and version of WiFi you are attempting to connect on
(ex. 802.11n)?

** Tags added: latest-bios-3.03

** Description changed:

- I obtained a lenovo y50-70 a few weeks ago, and installed ubuntu 14.04.3
- LTS on it (dual boot with windows 8 that came pre-installed).
+ The rtl8723be wifi adapter rarely connects to a network. When it does,
+ it will be choppy (10% to 50% packet loss on a ping to the default
+ gateway) and usually disconnect after a few minutes.
  
- $ lsb_release -rd
- Description:	Ubuntu 14.04.3 LTS
- Release:	14.04
- 
- I have not been able to get the rtl8723be wifi adapter to work yet.
- 
- If it will connect to a wifi network at all (which is rare), it will be
- choppy (10% to 50% packet loss on a ping to the default gateway) and
- usually disconnect after a few minutes.
- 
- The internet suggests a few work-arounds:
- 
- - run with fwlps=0 ips=0 as options to the rtl8723be module (eg. http://askubuntu.com/questions/590414/wifi-problems-with-rtl8723be-in-ubuntu-14-04)
- - install an alternative driver (eg. http://askubuntu.com/questions/590414/wifi-problems-with-rtl8723be-in-ubuntu-14-04)
- http://paste.ubuntu.com/1230961
- 
- However, none of those suggested worked for me.
- 
- I have tried downgrading the kernel down to 3.13.0-62, and various
- kernels in between, but none of that helped either.
- 
- Output of the wireless-info script here:
- http://paste.ubuntu.com/12309610/
+ Run with fwlps=0 ips=0 as options to the rtl8723be module, or testing
+ https://github.com/lwfinger/rtlwifi_new/ didn't help.
