[Solved] Wireless network not detected sometimes

[askhanduja]

Hi,

I am using 64-bit Linux Mint 17.2. I use the Cinnamon desktop.

The issue I am facing is that my wireless connection is not detected sometimes by Mint. It works just fine though once I restart my system. Would appreciate any help to solve this issue (of not detecting wireless network sometimes).

Following is the output of the command: inxi -Fxz

Tried strengthening the signal using the best channel. Will let the results be known in a few days since the problem occurs only intermittently. Thanks a lot for the help. Great work that you are doing here pjotr.

Haven't faced the "no connection" issue in the past few days. Seems the problem is solved. Thanks for the help.
