Questions about upgrading the WLAN Card in an Alienware 18

So my Alienware 18 has the Broadcom 4352 WLAN card but I've been experiencing a lot of random disconnections ever since I got my new router (an ASUS RT-3200 Tri Band Router)

I was thinking maybe to upgrade the WLAN card.

I have a questions though, on my previous Alienware 18, I did swap the Broadcom BCM4352 card with my Wireless-N Killer 1202 but couldn't help but notice (while on Windows 8.1) that the Radio Switch driver when installed still says Broadcom so I am thinking, how is this so, I changed my card but there seems to be like some sort of Broadcom Wireless switch (radio control) driver separately? wouldn't that be a problem? or maybe it wouldn't even work? I can't remember if it did work as that was a long time ago that I installed it.

Another question comes to my mind is, which is the best WLAN upgrade for my laptop? I know the new Wire-ess-N killer cannot be installed because it's in a new form factor.

If you were in my shoes, what would you do?

1) Keep my BCM4352 which disconnects randomly
2) Install my Wireless-N Killer 1202 and get better ping rates but old technology (as in no AC speeds although bear in mind that my internet connection is 50 MBPS Down / 10 MBPS UP)
3) Buy an Intel Dual Band Wireless AC7260

Please help

 

Also, if I did opt for buying the Intel one, which of these would work? I see the 3rd one has different connectors:

2) http://www.amazon.com/Intel-Dual-Ba...8&qid=1425159861&sr=8-2&keywords=Intel+AC7260

3) http://www.amazon.com/Intel-Dual-Ba...8&qid=1425159861&sr=8-2&keywords=Intel+AC7260

 

Sorry, I couldn't stop laughing at that ridiculous router of yours . What do you use that thing for? You do know that anything more than a $100 AC1750-class router is pretty much a waste of money, right?

But I digress. Just get an Intel AC 7260 and be done with it. And not the ones you linked, either. Get the revised version such as this or this.

 

I don't know why I bought this router man, paid $300 USD for it and it disconnects like hell! worst investment I made

 

Return it and get a TP-Link Archer C7 V2 or Archer C8.

Why do I get the feeling you're swimming in green. Do you sell oil to western nations?

 

no man, actually been out of a job for a year and 3 months now but I believe in paying more for quality, seems like one shouldn't buy an ASUS router before 6 months pass till they have polished the bugs. I miss my AC68U router that never ever disconnected

 

I have like a 30 dollar Asus router that I've used for years flawlessly sorry just had to put that out there

 

Then his router must be 10x better!

 

Get the 7260AC and be done with it. The first amazon link is fine.
