[Solved] Mint 17.2 Cinnamon Wi-fi problem

[deepakdeshp]

Hello,

I am able to connect to wireless network. It also indicates the signal strength but I am not able to connect to the internet or my router . Please suggest. When I connect other devices like Windows or my phone there are no problems.

Please generate an overview of your system like this:
- Launch a terminal window (this is how to launch a terminal window);
- make the terminal window full screen, to avoid chopped lines;
- copy/paste this command into the terminal:

Code: Select all

inxi -Fxz

(if you type: the letter F is a capital letter)

Press Enter.

Copy/paste the output in your next message.

OK.... You should be able to fix the driver for the RTL8723BE chipset like this:

But is it driver problem? The command output when connected to Wireless is as follows. In this situation no internet connection is possible

Trust me, the driver needs that fix anyway....

If that's not enough, I suggest dumping the unsupported 4.x kernel and use the latest supported kernel from the 3.19 series instead:

Bulls eye sir. Many thanks. The link had power management option for my chip set 8723 . I followed the tip and it is working fine.

Lesson:- Level 1 guy should not argue with a level 10 master.

P.S. I was not entirely wrong. It did not require a driver , just power management.
