While powering the tablet the wifi often after a few minutes just looses connection and refuses to reconnect. Turning it off is working but turning it back on just does nothing. A reboot does not fix it. No wifi connection. Wifi is turned on after a reboot but it does not find anything while searching.
Any tips ?

Update: Now it even dropped without charging and by only playing back some video. Error message I see with dmesg is
CFG80211-ERROR wl_is_linkdown: Link down Reason: WLC_E_LINK
Trying to reconnect gives me
CFG80211-ERROR wl_scan_timeout: timer expired
It seems to me that it is some kind of driver issue.

Update2: Was able to get wifi going again by devel-su and entering ifconfig wlan0 down && ifconfig wlan0 up

Update2: Was able to get wifi going again by devel-su and entering ifconfig wlan0 down && ifconfig wlan0 up. Though this does not work everytime. Still think this is a driver bug in the kernel.

Update3: The bug seems to be reproducable everytime when streaming long media streams with gstreamer (e.g. LLs VideoPlayer or a Youtube video on Webcat)

Steps to reproduce: 1. Open LLs video player 2. Open https://www.youtube.com/watch?v=tG_lvirWXTg Youtube video stream 3. Hit play
Result: Randomly the stream aborts loading as wifi drops dead
