Wireless device disconnecting unless reboot

Post by Matto_Fracico »

Hi all,
I have this issue: during the first 10 mins the wireless card works fine but suddenly cannot download data anymore and after 1 or 2 mins disconnects.
If i try to reconnect it just wont do it unless i reboot the laptop.

I have apparently a realtek RTL8723 and i have tried already many solutions posted everywhere with no results, i am also very new to this world.
The OS is linux mint 17.1

this is the mintwifi results (no idea what it actually is!!)

to generate this post i needed a connection so I used my android device.in fact the wireless connection is present but useless.
I have also tried the windows drivers with ndiswrapper but the wirless network simply disappeared.. :shock:

I am seriously lost.

In terminal enter

Code: Select all

 for p in /sys/module/rtl8723be/parameters/*; do echo $p; cat $p; done
and paste results in a post. I would also uninstall ndiswrapper as it might interfere
