tl;dr -- WiFi works but very slow, whereas Ethernet works fine. Multiple troubleshooters did not help, and I'm not sure about the driver I need
Long time reader, first time writer, and generally new to Linux Mint. I have a relatively fresh install of Linux Mint 17.2 Cinnamon Refaela, and the WiFi used to work fine, but now it doesn't.
Options considered and eliminated:
- not router as other devices work fine
- not Internet connection as a cable connection is very fast (240mb/s vs. 0.3 mb/s with WiFi).
- system is fully updated
I have read several guides on the subject (eg. https://goo.gl/jiQNhc) but at the moment I'm a bit confused in regards to my physical WiFi card: on the one hand HP says that my model, 4720s, has Atheros 9285 (http://h20564.www2.hp.com/hpsc/doc/publ ... -c02057767) but on the other hand some reviews (eg. http://www.notebookreview.com/notebookr ... 0s-review/) says I have the RALINK 3090. Running some commands on terminal say the same, but I consider the possibility that I just got the wrong drivers (not sure how). My BIOS isn''t being too helpful...
So my first question would be: how do I know what card I actually have?

and also, sudo mintwifi says (I've omitted irrelevant output):

As far as I can tell the settings are "correct" in the sense of disabling encryption key, power management etc.
At this stage I would mostly want to just re-install the driver, but I'm not sure how to do that: where and how do I get the driver for my network card?
Note that most guides and tips refer to non-functional WiFi, but here's the case is a bit different, just slow...
Many thanks for your help -- and let me know if I can post anything else that could provide useful information
