When I was in contact with Dell Technical Support on my specific issue, I was told that there are other laptops out there with the same problem i.e. wrong card. Suggest you call them and escalate.
Actually I even don`t have a 5Ghz router, I was trying to solve my wifi problems when I realized that there was no option to choose 5Ghz. By that time I thought that maybe the problem was the wrong card.
Do you know if I have to have a 5Ghz router to appear this 802.11a? Or even if I don`t have this radio type should appear?
By the way, my wifi is working now since I downgrade the wireless drivers until 220.127.116.11.
i have the same issue. next week a techician will come and install a new wifi card in my 7537. But is your laptop fixed now? Because i am affraid that he will install the same wifi card that i own now...

I had the same concern so I asked them to send me a replacement laptop, just to be sure. Dell agreed and I am scheduled to receive in early January 2014 due to shipment backlog.
A technician replaced my lcd/antenna kit 2 days ago. No improvement...
Today he came back with 3 wifi cards. 3 different cards. At first the cables of the antenna came loose so he will come back to replace the lcd/antenna again. But with a quick fix we both noticed that none of the cards improved the wifi speed.
I use an external dlink wifi adaptor and i get speeds up to 25mbps. With the original internal intel cards i got 15mbps at max.
The tech told me he was affraid that this 7000 series have the same problem like the xps models. The alu cover of the screen causes all of these problems and that the only solution is asking my money back because the replacement laptops will probably all have the same issue.
I ll give and update when i have some more news about how they will solve this. I am not going to wait yet another month for a solution.
I just wanted to add that I ran into the exact same issue with my Inspiron15 7513 that I bough on 12/30/2013. I was wondering why I could not find any 5GHz settings in the adapter properties, and this post confirmed the issue for.
Today I was on the Phone for over an hour with tech support and customer service, and at the end I was told that there had been a mistake in the order page and the order confirmation where the WiFi adapter had falsely been described as dual band. When I asked if they could ship me a dual band replacement card, I was told that none of the Inspiron models came with a dual band WiFi card and that Dell therefore could not upgrade me to one.
My only option, I was told is to return the device for a refund.
Unfortunately, the 2.4GHz 802.11N WiFi performance of this notebook is very bad, compared to my older XPS 15 and any other notebook I have used in the same place in my house. Even after the upgrade to the latest drivers from the Dell support page.
I find it scandalous that Dell has to this point not changed the product description on their webpage, even though they know it is false. I almost seems as if they are counting on the fact that many customers would not be able to tell the difference anyway, and that the hassle of a return might deter the rest.
I am wondering if I could just buy a dual band card (802.11ac, dual-band, 2x2 Wi-Fi plus Bluetooth available for $25) and replace it myself.
Agreed, it is scandalous that they would advertise a product and not manufacture it according to their own specs.
I know that this might sound callous, but companies like Dell are hurting in the PC space and so their basic instinct could be to turn a blind eye to these types of issues as it costs them $$ to fix. That is unfortunate as we are the loyal customers paying for their products. The only thing I have ever asked Dell for in my case is to make good on their original laptop specification.
However doing a return is a hassle. Also replacing the wifi card with the AC model is simple (2 screws and antenna connection swap fully detailed in the owner's manual), and it is relatively inexpensive. My advice for you is if you like the laptop and would like to keep it (I know I do), replace the card yourself and move on.
Same problem. The system is still advertised on the Dell website as having dual band, but the support people claim the invoice is incorrect.
Wifi performance is significantly worse than my 5 year old Del.
UPDATE: after the web chat where Dell claimed that my invoice was incorrect, I called and talked someone else who was much more helpful - after reinstalling drivers, tinkering with settings, etc. they agreed that the wifi card should be replaced. The next day a tech came and replaced the single band card with a dual band card. Wifi performance is now better than it was, but still significantly worse than my 5-year-old Dell laptop.
