Wifi not working (sometimes)

Hi guys,

I am new to ubuntu so I need your help with something.

Sometimes, wifi is not working and more specifically wifi networks list is hidden. When restarting, the problem seems to be solved. Have you any ideas or suggestions on this?

Thank you in advance.

Hi Kabapot,

Have a look here, see if that helps

How to solve internet connection problems

That is good advice, but it is also possibly the “nm-applet” problem.
There is lots of help about it on the net, most of which “helps” , but I
am yet to find definitive advice that fixes it completely that I can
point you to. I find the wi-fi “disappears” when my laptop “suspends”,
and then resumes. It starts ok from a cold start.
