ASUS S56CA-XH71 Ultrabook NIC

I have been reading here since I purchased and received my Ultrabook and this site is a ton of knowledge.
The Asus Ultrabook I purchased has a wireless NIC that is junk, actually if I had known Asus used such junk NIC I would have never bought the Asus computer line period.
The first computer I have is the U56E which is right around 8 months old which the wireless NIC works fine on the low end of the router b/g/n 2.4GHZ, but won't see the high end 5 GHZ, then I purchased and received my S56CA this past week and I am very very annoyed with the wireless NIC in both machines, more so in the S56CA since it does not run 100% and will drop connection.
I know some of this is my fault, but the majority of the fault rests with Asus, they need to give a thorough detail of the listings with their machines, especially their Wireless NIC does not support full wireless N and will not work with all routers.
Yes I read the details on the S56 on at least 15 sites, they are stated wireless N, which yes it possible works with wireless N, but the low end of the router it works on is b/g/n 2.4GHZ so who knows if it is actually working straight wireless N and the speed is quite less to be desired. My 2007 Dell Lattitude I replaced with the S56 would run circles around this new machine in regards to the wireless NIC.
I also filed a complaint with Asus today, so who knows if anything will be done or corrected.

Anyway enough of that, what I am looking for since I go to the sites where the professionals are which wireless NIC card would you replace the Atheros AR 9485 in the S56CA machine with?
I have read here Intel 6200 and 6300 is recommended
Even read good things about the Atheros AR9380

So what does the pros say?

 

The frequency it operates on has less bearing on network speed than you may think. The GHz range of a wireless radio only partially relates to the speed of a wireless network. A 5 GHz network can carry more data than a 2.4 GHz network assuming the electric power to the higher frequency radios is maintained at a higher level. However, some 802.11g network products match and even exceed this potential speed advantage of 5 GHz 802.11a by utilizing a pair of radios instead of one, increasing capacity up to 108 Mbps under the right conditions.

The real advantage to 5 GHz range is that a lot of other devices operate on 2.4 GHz, so you'll better sidestep interference by running off of the higher frequency.

You can read more here: Is 5 GHz Wi-Fi Wireless Computer Hardware Better than 2.4 GHz?

Your poor speed could be due to a bad driver, a faulty card, or excessive interference (assuming your router and ISP are fine).

I seldom hear bad things about the Intel Advance, so if you're looking to upgrade, I would say that's a solid choice.

 

Thank you sir, I ordered a Intel 6235 and 6230 today just to make sure they work and will change both cards out on my ASUS computers.
I did learn something today as well I want to share with everyone, Do Not Trust or rely the specs given by a supplier or seller if you want to know the exact specs on a ASUS Computer you need to go to ASUS and read the specs.
Someone is not getting their specs straight and ASUS specs are different in regards to the NIC in this machine compared to all the other sites I looked at in the time of purchasing this machine.

 

Stock NICs usually produce the bare minimum performance, so I'm not surprised if what you got did not - in fact - omit support for the 5 GHz frequency. Sorry to hear you weren't happy with it, but in any case, I hope your replacement treats you well!

 

You know the funny this about it, my old 2007 Dell with the bare bones factory NIC ran circles around this 2013 ASUS's NIC.
I have expressed my extreme disappointment with their quality of parts and the crooked way they want me to purchase the recovery CD and Operating System for my machine.
Never in my life have I ever been informed I had to purchase a recovery CD or OS that came on the system every company I have ever bought a computer from regardless of desk top or Laptop always said the price for the software was included, this is my second ASUS in less than a years time and it will be my last, when I buy again I am going back to Dell and long as Dell does not try to pull the crap ASUS has pulled.

Now some will ask why did you buy a second ASUS, but my wife's ASUS came with cds' which was purchased in April of 2012
