Ubuntu 14.04 LTS: Cannot reconnect to the wifi. (HP Pavilion 15 15-p264na)


I currently run Ubuntu 14.04 LTS dual-boot with Windows 8.1 and was hoping to find a solution for the wifi connection dropping around every 15-20 minutes. I followed praseodym's solution on:
http://ubuntuforums.org/showthread.p...7#post13003107
and rebooted but could not connect to the wifi afterwards; I looked around for solutions using ethernet connection but couldn't find a solution that worked for me (or I didn't look hard enough).

Unfortunately I can't provide an lspci result as I am typing this from Windows but I do know that I was using the Realtek rtl8732be driver, and it has been much trickier to solve connection issues compared to my old Dell Ubuntu laptop which used Broadcom.

I'm running out of ideas, does anybody have any suggestions as to how to reconnect to my wifi again?

lsmod?
ifconfig -a
dhcp or static ip adress?

Thanks for replying, the ethernet is in a dodgy place so I'll have to come back later so I'll leave this here:
