networking - WiFI not available after installing TLP on Ubuntu 14.04

This afternoon I installed TLP on my laptop running Ubuntu 14.04.



After the restart my WiFi suddenly stopped working
_ message: "Disconnected - you are now offline"
- I have a button on my keyboard that turns wifi on/off - now it just stays red and doesn't change (to blue) at all when pressed.
- In my network indicator now there no option even to turn wifi on/off and its the same in system settings





  • RFKILL LIST ALL gives me:



hp-bluetooth: Bluetooth
Soft blocked: yes
Hard blocked: no


And no wireless mentioned at all.





  • Attempted fixes: (that did not work)


    1. Change the following in TLP's configuration:




WIFI_PWR_ON_BAT=1
WIFI_PWR_ON_AC=1




  1. sudo service network-manager restart


  2. I then uninstalled TLP (and purged) - still nothing


  3. I then uninstalled other things I installed earlier in the day: Weather and calendar indicators, and preload.




    • NOTE: i noted in my software center there was 3 changes in the history that i did not recognise: Removal of : Python3 tz, Python dateutil and python3-dateutil (I do not know what these are signifying)





I do not know what wireless card I have or how to find that out.



Kindly assist me please



EDIT:




  • Wireless card: EDIT: found this: RTL8101/2/6E PCI Express Fast/Gigabit Ethernet controller

  • Running the following didnt change anything




    sudo add-apt-repository ppa:hanipouspilot/rtlwifi
sudo apt-get update
sudo apt-get install rtlwifi-new-dkms-linux-firmware
sudo apt-get update && sudo apt-get upgrade


Edit: Seems like my wireless driver has been uninstalled somehow? am I interpreting this correctly?



sudo lshw -c network



Output



description: Ethernet interface
product: RTL8101/2/6E PCI Express Fast/Gigabit Ethernet controller


Nothing saying Wireless interface???
