I've got the 6230 and a Billion 7800n, windows 7 64bit, latest drivers and firmware etc. I've got 3 other laptops connecting with wireless n fine.
The card says it connects but there's no internet connection. I can see that it's got the gateway address but pinging it does not work (works for other laptops). The router system log is full of "DHCP SERVER: DHCP request from laptop" and the router's reply "DHCP SERVER: DHCP ack to laptop". Other laptops do this once where as my new laptop just keeps on going.
Now I know that there's been a lot of problems with this card and Intel haven't addressed it yet. The solutions that work for me are either disabling wirless n on the card which is unacceptable because I lose speed which was the point of buying this card. The other solution is to reinstall the driver which allows the card to work perfectly. I can restart my laptop and it will run fine again. It's the 3rd boot that what ever magic the reinstall did, fails. This happens 100% consistently. So does this mean that it's a driver/software problem?
I really don't want to have to keep doing this alternative solutions because it should work. If Intel advertised the card as one i'd have to re-enable on startup I would not have bought it...
Anyway enough ranting. Can I get a confirmation from an Intel support person that this is a problem and they are working on a solution?
I humbly apologise to Intel, the problem was due to a conflict with the intel card and my current bios firmware.
For others who might run into this problem, I have a Clevo P150HM laptop. They don't make their bios firmware releases public so you have to request it specifically from their support team. However there is a thread here: http://forum.notebookreview.com/sager-clevo/416916-clevo-bios-thread.html which lists firmware obtained by customers. I hope this helps anyone else in this situation.
Since recently I'm having the exact same issues on my Sager NP8150 (which is basically a rebranded Clevo P150HM) also with an intel advanced-N 6230.
Might I ask which BIOS/EC versions you used to solve the problem, and how you configured your pc to reinstall the drivers automatically on boot?
