[solved] cannot connect to wifi

[Fraggosyko]

Hello from Greece,
Yesterday everything was ok but today morning my laptop cannot connect to any wifi, not only to mine. On the other hand other devices like my android can connect. Turning the laptop off and on does not solve the problem. Here is what I gor by typing in terminal the mentioned commands

OK, first of all: why kernel 3.10 for Mint 13? That's not a supported kernel for Maya.... Do you have the same problem when booting from a kernel from the 3.2 series?

Secondly, it might help if you disable power management for the wireless chipset, and disable hardware encryption:

Thanks for your quick answer, but I don't know even what the kernel is, what version I have and how to change it. I was using this laptop without making any changes, at least I know about, for 1 year now. Till yesterday everything was working ok.. 12 hour later, today, without making any changes, the laptop is not connecting anymore.. The only thing I did is shutting the laptop off...
I figured out that my laptop has the indication of wireless modem at the f12 button, I pushed it and now after giving iwconfig in terminal I got this but no connection again.

upgradind to mint 17.1 will solve the problem? I wanted to upgrade anyway, so maybe this is the time?

That sounds like a good idea.... If there's still a problem then (hopefully not), getting help with troubleshooting will be easier. Because most forum members here, are already running Mint 17.1 on all of their machines.

I succesfully iinstalled mint 17.1 and the problem is solved, thanks
