I have an Intel 6230 Wireless N network card in my laptop, and it connects to my network just fine and can access the internet when 802.11n is disabled. However, when I enable 802.11n mode in the adapter properties, everything goes wrong. I lose network and internet access, although curiously enough, Windows will still detect all wireless networks in range, and it will also tell me that I am connected my home network with limited connectivity. At this point I cannot access my router setup page, so I am unsure how Windows figures I am connected to my network at all.
I have a desktop being used as a Minecraft server that connects to my home network through 802.11n at 300Mbps just fine, so I know my router is setup correctly and everything is working there. Security settings for the router are WPA2 on AES, which I've read is required for Intel adapters on 802.11n to access network speeds above 54Mbps.
Has anyone encountered this issue with their network adapter? It seems redundant to have a 802.11n adapter if it only works at 802.11g settings. I am beginning to think the card is a dud, however it just doesn't make sense to me that it connects fine with 802.11n disabled, although when enabled it will still detect wireless networks in range.

Wallzii, windows 7 does not always accurately report conections from what I have read and experienced.
Try connecting the laptop directly with a cable. Delete the network from manage wireless networks and set it up 'fresh'
Also your router may be quirky, could you please post the brand and model? -
What's the router in question? Id the firmware up to date?
Did you upgrade Wi-Fi drivers? -
The router in question is an SMC Networks model SMCD3GN, firmware up-to-date. My drivers for the wireless adapter are also current. Sorry, I meant to provide that information in my first post.
I have deleted all the networks from the manage networks screen and refreshed my network, and the same problem persits; wireless G works fine, wireless N does not.
I have also reset the router to its factory defaults and that did not remedy the issue either. Still, my desktop with a D-Link 802.11n adapter connects at full bandwidth just fine. -
I'm afraid you'll have to play with advanced network settings on the router.
Check what happens if you change it to "Green Field" which should be n-only. -
You need to set 802.11n Channel Width for band 2.4GHz to AUTO
Intel 6230 doesn't get internet access when "N" mode is enabled; what gives?
