Wifi disabled by hardware switch on hp pavilion G6 2231-tx

Question

I have a hp pavilion G6 2231-tx laptop running ubuntu 14.04 and windows dual boot. The wifi on my laptop is not working in ubuntu. It shows Wi-fi is disabled by hardware swith when I hover over the network icon in the top right corner of my desktop.

I have seen several posts like:

How do I fix a "Wireless is disabled by hardware switch" error?

Wifi disabled by hardware switch

and many more.

Things I have already tried:

1. Checked the bios.
2. Hardware switch on my keyboard(f12/fn+f12)
3. rfkill unblock all
4. Install wifi driver,Installing Broadcom Wireless Drivers (lspci -nn -d 14e4: returned no result though)
5. Checked /etc/modprobe.d/blacklist.conf what's blacklisted.

but those were of no help. Pls suggest a solution.

Edit

lspci -knn | grep Net -A2; rfkill list returns

07:00.0 Network controller [0280]: Ralink corp. RT3290 Wireless 802.11n 1T/1R PCIe [1814:3290] Subsystem: Hewlett-Packard Company Ralink RT3290LE 802.11bgn 1x1 Wi-Fi and Bluetooth 4.0 Combo Adapter [103c:18ec] Kernel driver in use: rt2800pci 0: phy0: Wireless LAN Soft blocked: no Hard blocked: yes

EDIT2

Now I followed this: Ralink rt3290 wifi driver is not working in Ubuntu 14.04

Now the message that "Wirelss is disabled by hardware switch" is removed but now there is no wifi signal at all. now rfkill list returns no result.

This is not an Ubuntu issue. This is not any driver issue. This is caused by me (and possibly you).

While watching some video... I tried to increase volume with: Fn + F10 key combination ... But I mistakenly pressed Fn + F12 which was Wifi button with 'Radio' symbol on it, which disabled my wifi connection.

Running below command in Terminal, you can see the issue:

> rfkill list all
    
    0: Toshiba Bluetooth: Bluetooth           #or whatever it is
        Soft blocked: no
        Hard blocked: no
    1: phy0: Wireless LAN
        Soft blocked: no
        Hard blocked: yes    `<------ that's because I press Wifi button (above) `mistakenly`

Solution: Press again the Fn + F12 (or, some other key where you have Radio symbol)

Now run again the same command:

> rfkill list all

    0: Toshiba Bluetooth: Bluetooth           #or whatever it is
        Soft blocked: no
        Hard blocked: no
    1: phy0: Wireless LAN
        Soft blocked: no
        Hard blocked: no

    <------ no means solved.

Now, go to:

(Windows button, if you have on the keyboard) > Settings > Wifi > move to On > select your Wiki connection to enter credentials

Done, your internet is back on.

I hope this works ...
