They changed the WiFi network configuation going a year now and I didn't have the N900 until a month ago. I never tried to configure the N900 against the old Windows 2003 IAS server. That's back when I was using the N810. Sorry for introducing too many variables into my original post. I've long since given up on the N810, since my understanding of bug 3914 is that the N810 will never work against Microsoft NPS RADIUS.

The settings required for our network (WPA, PEAP, MSCHAPv2) are well documented and, as I said in my original post, my Windows laptops and iPod authenticate fine. I only include that information to try to offer up the idea that I'm not utterly clueless, not to suggest that the N900 is an inherently inferior device that won't work for anyone.

I came across the "PEAP + MSCHAPv2 WiFi Authentication Setup" page weeks ago and all that did was to tell me that I already knew what settings to put in my N900, despite the fact it doesn't work for me on our campus (where I work). At the bottom of that page it says, "If you're uncertain, try if step-by-step guide below works. If it doesn't - bummer."
Bummer, indeed.

I get human nature is to protect one's own code or favorite device against all negativity, whether justified or not. I also get the slapping down on the "mee too" posts. Given the complexity involved, at this point the Maemo developers are going to need logs to look at and I keep hoping that the several people that are in fact giving them logged details across several different buzilla entries will eventually lead to a breakthrough. The point being, I'm not the only one on the planet having this exact issue, even if it is only affecting a small number of N900 owners.

In truth, I've already pretty much given up on the N900 for work and moved on, especially given all of the Android-based devices coming out within the next few months that look to be amazing. I can still use the N900 at home and at friends' houses, just not at work, at least not currently.

We use the Thawte Server CA certificate, which is included on the N900. However, I did in fact get the exported cert and installed it, but it still didn't work.
