BT/WIFI issue

[Hans Sprungfeld]

It’s normal due to a bug in the Realtek chip of its power management features. There is a workaround on Windows:

The process is short as all you need to do is to change a registry key at:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E972-E325-11CE-BFC1-08002bE10318}\000X

(X may be one of 0 / 1 / 2 … )

Search for and change the value of bLeisurePs from 2 to 0. Can be 2 settings so look carefully. This deactivates the wifi chips power management.

Reboot.

Hi, I have the same issue on my other tab, don’t with my Cube

The solution for my other tab is

Disable wifi
Reboot
Connect your BT
Activate wifi

Don’t know if it’s work on cube

so now my feedback

yesterday i have changed this settings, but no luck the speedtest was terrible (checked the settings 3 times  and 4 reboots)

todayi bootet the tablet and i tried to use an external BT Dongel, but no luck, the dongle had an error in the driver lib created.

i unpluged the dongle and checked the  speed again — it works now fine

i also changed now the BT settings (energy options, that the system cannot daektivate the BT Mouse)

but i think the main improvement was the regedit change.

 

Thanks a lot.

Nope. The workaround works. I guess you did something wrong / not what I told you.
