It is my opinion that the wifi router is not the culprit, because:

- i have tried to connect to various wifi routers in various locations, all with the same issue:
   - at home I have a linksys wrt54gl v1.1 w/ OpenWrt Backfire 10.03.1 / LuCI 0.10.0 Release (0.10.0), that's an 802.11b/g router
   - i also have a GL-INET router w/ OpenWrt Barrier Breaker r38451 / LuCI Trunk (svn-r9971) , that's a 802.11bgn router
   - the appartment building here has an own wifi network, which is a cisco system with transceivers and a central controller, i have no clue about the models, firmware versions or capabilities of that network as i do not manage that
   - at a club-building i often come there is an aruba networks system, also with transceivers and a central controller, where I have the same problems connecting with ubuntu - no clue again of what firmware etc that is not my equipment
   - when setting up my samsing galaxy note 4 as a mobile access point, I have the same issues connecting this laptop when running ubuntu
   - at work, i don't have a clue about the make/model/firmware of the wifi system there, but i know i also have the same issues
   - at various public venues and hotels i tried connecting, resulted in the same issues
   - i have tried connecting to the wifi when visiting friends or family, it will be near impossible to make a list of all those ap's and their make/model/firmware versions, but i never was able to get a usable connection there either
   - all other devices in the house (several other laptops w/ windows or ubuntu, android phones, android tablets) connect to both of my own routers and the appartment building routers without any issues
- when booting into the windows installation that is also on this machine, i can connect to all those networks flawelessly and stay connected without any packet loss over prolonged periods

hope that helps.

Title:
  rtl8723be wifi unusable on lenovo ideapad y50-70

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  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.

  Run with fwlps=0 ips=0 as options to the rtl8723be module, or testing
  https://github.com/lwfinger/rtlwifi_new/ didn't help.
