I'm having a similar problem. A MacBook Air, two iPhone 4s, an iTouch, an iPad2, an Adroid, and a 2 Windows laptops, and all are at 11n but the iphone 5 which always negotiates at 11g. I'm using a D-Link DIR-655.

I have the same router. If all others are at 11n then this has to be the phone...
How are you speedtest.net results? Mine seem to be fine - equal to my desktop at about 24Mbps down and 4.75Mbps up.
Maybe the phone is just reporting it at 11g when it's really 11n... no clue.

What happens if you "forget" the G network in your phone settings and have it only connect to the N network.
Reset the Networking settings may be a good idea after that, it will just force you to re-enter all your WiFi passwords.

There is only one network Wireless Access Point that excepts both G & N, but it negotiates G. I did a reset Network and it still negotiated as G. I did the very same thing with an Iphone 4, and it negotiates at N all the time. Anyone else having this problem with the iPhone 5?

Dibert..That is very odd then.
I would try to find another Wireless N network to connect to, just to see if the phone can connect to it. On my router it is a dual band, so it operates at 2.4Ghz and a seperate 5Ghz, my iphone 5 connects to the 5Ghz with no issues.

The problem is that the phone doesn't tell you if it's connected to G or to N so how would you know except for looking at the router itself.
I tried all the above... actually I've seen this with two iPhone 5s and both only showed G connection.

I see your point lol. my 5GHZ network is N only so I know its connected to that network because it has a different SSID.

I changed my router to 11n only and could not connect with either iPhone 5 or Apple TV. I found and turned off the setting for "Advanced > WiFi Protected Setup" and now I get connection. And the router's wireless status still shows 11g for the phone and 11n for Apple TV.
So.... The router's at 11n and the iPhone 5 is connected and getting good speedtest.net results but the router shows it at 11g. Seems like if it was really at 11g then it could not connect to the router... weird!

Very weird...WiFi Protected Setup should only be used if your devices suppport it..usually a push button on a router/extender or like Blue-Ray device. If your router was setup to only accept those that have WPS on, then you found your culprit.
Still dont understand why the phone is seeing it properly or showing that its connected to the N speed. You would only see the N speed on sharing of a file locally, since your internet connection is not going to be near 100Mbps-300Mbps lol.

I wonder if there's a app for that... to tell you what is your wifi setting - 11g or 11n? Or maybe a website to connect to that will tell you...
Actually, I'm done messing with this. My speeds are great so I'm happy. (Still, darn curious though...).
