Looks like I spoke too soon. I am still having problems with iwlagn. I have an Intel Centrino Advanced-N 6200. The problems are intermittent: when downloading a file, the download will simply stop at some point (when downloading using Firefox 4 or wget). The same thing happens when streaming from YouTube. Here is the output of dmesg immediately after a download degrades and then grinds to a complete stop:
