[Solved] Restart wifi needed after shutdown w/ wifi disabled

[klaplong]

Hi all,

I am running Linux Mint 13 MATE 64-bit on a Dell XPS 15 (L502X). Though I know this isn't the best supported laptop there is for Linux, I generally love my Mint experience.
Despite this, I have one problem, which is humongously annoying. One time I manually disabled WiFi through the Fn + F2 combination on my keyboard. After this, I shut down my computer. The next time I logged on, my WiFi wasn't working. After turning it off and on again through the hardware keys, it worked.
The problem didn't go away after shutting down with working WiFi, so you can understand why this is such an annoying problem.

I have tried searching the internet, but I couldn't find any useful leads. I also posted my question on the IRC-channel a couple of times, but I didn't even get a response (not even someone acknowledging they have read my question). I really hope someone can help me get this thing out of the way!

Cheers,
Klaplong

Try this. First open a terminal and run:

Code: Select all

rfkill list

I get this.

Code: Select all

rfkill list
0: acer-wireless: Wireless LAN
   Soft blocked: yes
   Hard blocked: no
1: phy0: Wireless LAN
   Soft blocked: no
   Hard blocked: yes

If I wanted to unblock these interfaces I would run

Code: Select all

sudo rfkill unblock 0
sudo rfkill unblock 1

Rfkill only unblocks 'soft' blocks, hard blocks are caused by hardware switches, but the soft unblocking might be all you need, try it anyway, it can't do any harm.

Awesome, that worked.

I just rebooted to try and surprisingly I didn't have to reset my wifi. That might have something to do with a kernel update I ran earlier today.
I disabled the adapter and rebooted, and I did get the problem. After running your code it worked again.

Thank you very much! I will mark the thread as solved.
