I have Lenovo laptop G50-70, which contains Realtek 8723BE wifi chip.
Under Windows-10 previews (from October release thru latest build#10047), this wifi
device does not work reliably. (And, mine is rock-solid under both WIndows-7 and
I've tried uninstalling present driver and re-acquiring the latest driver from the Lenovo
website (since driver is NOT available at Realtek websiite). The driver does work intermittently.
The symptom is that it will always find my access point by name, connect to it, and
get a valid IP-address. After that, a ping from the cmd-line sometimes works but most
times, even after a fresh reboot, the ping fails. on a few occasions, it has worked for
as long as half-an-hour...and then just suddenly fails. (e.g. freezes while using the
browser or while watching a streaming movie, etc)
[ My first workaround was to use an ethernet cable. But after six months, that was growing OLD! ]
EDIT: [ My newest temporary workaround is to re-install Windows-8.1 natively and
then install Win-10 virtually, using VirtualBox. ]
No need in repeating the how-to info shown in that other thread (about RTL8723BS)...I've tried
all these various 'recipes' and permutations....nothing will fix the problem. Three other people
have reported this identical behavior in the Lenovo support forum under Windows 8.1 64-bit,
but they have no answers there. (Lenovo support even seems to be confused at which wifi
device(s) get built into the Lenovo G50-70 !)
If you want me the start believing in Windows-10, someone NEEDS to resolve this issue!
You could START by unequivocally stating whether Lenovo, or Realtek, or Microsoft OWNS this issue !
[ i.e. no one seems to acknowlege or accept the responsibility to investigate/fix the issue.]
