Wifi cuts out when laptop isn't charging
I'm on Linux Mint 14, kernel version 3.5.0-170-generic(x86_64).
As of recently, I've noticed that unless my laptop is plugged into the charger, I can't use Wifi. I'll have a connection, and when I unplug my power cable, I'll maintain a connection for a few minutes, then I lose all access to my network; I can regain a temporary connection if I toggle wifi--but it will eventually cut out again.
I know for a fact that this was not happening (at least) June 1st-June 6th (or anytime before that). Not sure what could be causing it.
My laptop is an HP Spectre 14.
I appreciate any and all help.

I would be looking at power management settings
Re: Wifi cuts out when laptop isn't charging
As far as I know, Linux Mint 14 doesn't have something like this. I haven't changed any settings regarding power consumption at all ever. Besides, it's not turning off the wifi--I just lose network access. I can still see the wifi networks and connect to them, can't access the internet.JeremyB wrote:I would be looking at power management settings

Here you go. I was plugged in when this happened.

Can you get me another from after unplugging charger and losing wireless?
Another important question, why are you not using LM13 Maya or LM17 Qiana instead as these are the only LM versions with current support and updates

I have Mint 14 set up just how I want it. I'm afraid to update, to be honest. I need everything working and I don't even have a reliable way of making backups; it's not a good reason, but it's why.
Sure, here you go:

Re: Wifi cuts out when laptop isn't charging
I couldn't find much from the wireless script and that surprised me but a google search brought up a issue with a HP that was solved by simply going into BIOS and reset to defaults. If that doesn't work, a kernel update might fix it, try 3.11 or 3.13

Actually I did find something, what country are you in?
This might not do anything
Code: Select all
cat /etc/default/crda

cat /etc/default/crda
I'll give both of your ideas a try. I think I might end up upgrading to Mint 17 though.

There is a chance that the cat /etc/default/crda will have an entry at the bottom of REGDOMAIN=00, if this is the case
