Most reliable drive for intel wifi 2200bg?

[oversky]

I just can't stand with it anymore. My wifi lost connection 5 times in one afternoon while my labmate was happily surfing without any problem.

I am using v10.5.3.1. Last time I tried 11.01.0, I can't de/active wifi through Fn+F5 (I also updated Hotkey utility). So, which version do you think as most reliable drive?

The latest one that you can get through Lenovo's Software Update.

I'm using 9.0.4.26 which seems quite stable (driver date:10/25/2006). That's the number in Device Manager. Software Installer has it down as 10.5.1.0 . . . but I've never been quite able to figure out Intel's driver numbers.
