Having issues with my wireless card and Windows/Linux partitions

HHalo6 · 01-30-2016, 05:34 PM

Hello. Recently I've been trying to install Linux Mint on my desktop computer in a partition along with Windows 10. My problem is that when I run Linux Mint (also happened to me before with Elementary OS Freya and it lead me to get rid of it) on live or I try to install it, it won't detect my wireless adaptor. Neither in the installation (it says I have no internet, and the adaptor does not emit light)... and neither when I have it already installed (happened with Elementary OS).

The problem is, everytime I turn the PC on and load either Windows 10 or Linux it won't detect my wireless card. I have to unplug it and then plug it in again and it will work. As you can imagine this is not a valid solution for me so I would be very grateful if you could light the issue a little, because it is driving me crazy. Especially because I live with 2 more people and they do not know anything about computers, and I have to share my printer and some more things so if they cannot use these resources they will be quite mad at me.

Thanks in advance.

Reboot your computer as normal (wifi card inserted), and run this command. Pop the card out/in, then run the command again. Post both results in [code] tags so we can read it

Code:

lspci -vv | awk '/[Nn]et/' RS=""

(that's 2 double-quotes at the end)

Sorry, couldn't answer earlier. Here you go. First one is when the card fails, second one is when it is connected to my network.

Code:

Thanks in advance. By the way, sometimes it connects to my network but it says like I'm connected to a ... null network? I do not know how to explain it, but it works anyway.
I'll be looking forward to your answer. Thanks again!

Step 4

If you're using Linux Mint, try MintWifi.

Just adding extra info. I am not stepping on syg00 post. His instructions are good also.

Mine as a example;

Code:

Thanks, but I am using Xubuntu because installing Mint was a completely mess and I am very familiarized with the Ubuntu family.
By the way, the problem only happens when I reboot and start Windows and then Linux or vice versa, although it seems to not happen anymore when I go from Linux to Windows.
So the real problem is when I last started Windows and then I start Linux, then it is in Linux when it does not work.
Hope I was clear enough, thanks for you response!

Hmm - I would expect to see wifi in the output of that command. Try this instead - install inxi if you don't have it

Code:

inxi -c 0 -v 3

Given that last post, I'd say Win10 is hibernating the card. I've seen similar issues reported - faststart in Win10 maybe ?

Well the hardware is obviously found there (Network card 2), and (in this case) the driver is loaded ok.
Somebody (as in Win10) is disabling it. Can't offer anymore help.
