Thanks for posting.
I would like to recommend the following links in order to troubleshooting your system:
Something else you may consider is possible interference by other wireless devices so here is another link that will provide more useful information:
Hello, very similar problem here. I bought a Lenovo ThinkPad E330 with a Centrino N 2230 card, and it connects properly to various wifi networks (full signal, even checked the signal quality with inSSIDer) but it just drops the connection even if I keep it right next to the antenna. Sometimes I manage to load a webpage or two but after a couple minutes invariably the browser hangs and can no longer connect to any server, although in the Windows taskbar the network shows up as excellent.
I've reinstalled the Intel drivers and software (downloaded the most recent package on the intel website), deinstalled the Lenovo network manager bloatware, tried various networks and the problem persists.
Currently I cannot use my computer due to this issue.
(Windows 7 64 bit, driver v 220.127.116.11)

What are the recommended settings for 802.11n connectivity?
How do I improve my 802.11n wireless performance?
There are several variables that may cause a connection to be dropped.
Drivers: since these wireless cards must be customized and tested by the system manufacturer you should use the latest drivers available on the laptops website. If these still present an issue you may want to uninstall those and install the latest generic ones from Intel:
Interference: this would cause a connection drop in one specific area (i.e.: only at the office but not at home) and usually other devices connected to the same network and near each other would suffer the same way.
Firmware: the firmware of the router if outdated may cause unexpected behavior with newer devices.
Malware: certain virus and other malware may case connection drops, if the system used to work correctly in the past then began suffering from connection drops you may need to check the system and may need to do a system restore to a previous date.
Conflicting software: some computers come with more than one connection utility, try disabling all connection utilities and use only the one from windows.
Power: some power settings may disable the PCIe bus or specific components to save power, set your system to a maximum performance power setting and test again.
Heat: overheating may cause connection drops, you usually identify this issue if your wireless adapter completely disappears or also if after a while you get heat warnings or the computer turns off, make sure you have good ventilation available for the laptop.
Integration: this is an issue that would be handled with the laptop manufacturer, you identify it by checking with them, and they may have it listed as a common issue on these laptops. You would suffer from connection drops all the time and every network.
Failed wireless adapter: can be actual adapter or antennas that are damaged, you would suffer from connection drops all the time and every network, but no known issue has been identified by the computer manufacturer.
I have the exact same problem as Thomas on my Dell Inspiron 17R SE with Windows 8. I've tried a Puppy Linux Live CD, and this doesn't have the problem. The same goes for my company laptop (Dell Precision with Windows 8).
Even more, when I try to make a connection I get connected for a few seconds and then not only the connection on my laptop drops, but all wireless connections on all other devices (tablet, smartphone, another laptop with Windows Vista) that are connected to the same wireless network get disconnected.
It looks like when trying to connect from my laptop, the access point drops all the connections it holds. The wireless signal is still up, as I can see it in inSIDDer.
Any help on solving the issue us much appreciated.
I'm having exactly the same problem with a Fujitsu Lifebook UH572 with this chipset. It generally behaves itself with in our offices where we use some Zyxel WAPs (though it has difficulty connecting some times), it connected to my LG Nexus 4 acting as a wifi hotspot, but the user had problems at home and in our Italian and South African offices (I don't know the hardware).
Essentially, it would connect and stay connected then disconnect after 5-10 minutes. At his home, it also managed to crash his wifi router. I've updated the drivers, played around with settings and got nowhere. Eventually I disabled it and installed an Edimax USB wifi card which has been rock solid. Intel, you have a problem.
I've had the same problem as well, with Dell Inspiron 15z.
after Dell renewed all hardware without result, I have tried deleting all drivers.
This was the procedure:
- Uninstall Intel WiFi Dashboard
- Uninstall adapter from Computer Management, DO also uninstall drivers.
- Restart computer
- (do the last step 3 or 4 times, until you reach Microsoft drivers 18.104.22.168, date 5-12-2011)
This helped and my problems are now gone!!!
As you can see, Intel is either too incompetent to solve this issue or are too lazy to find a solution. How can you make a product that consistently fails to work? Without even trying to find a solution? I have returned 2 computers solely due to the fact that this crap wireless adapter causes the laptop to be complete garbage. Hopefully, someone with a brain that works for Intel can actually resolve this problem instead of the multiple monkeys currently working on it.
You may want to try the latest driver version 15.8 since some users reported it solved the issue for them. Also make sure your access point has the latest firmware installed.

I have a similar problem...kinda.
In my home, My laptop has no problem getting wifi conection, BUT when I do, my cousin that has a laptop too, has no acces to internet.
Right now I'm in my uncle's house, where 2 cousins have laptops (an Asus, like myself, and a Dell) and we are having difficulties connecting to internet.
If I'm connected to internet, one of my cousins can't, or if they have, I can't connect.
Is strange when the 3 of us can be connected at the same time.
I dunno what to do, it was not happening when I bought my laptop, and I haven't installed anything strange besides the 15.8 driver.
(My Asus is Windows 8, the other Pcs are Windows 7)
