That's a coincidence. I'm using a D-LINK 655 (Rev A4, vers 1.34NA). Again, I've only seen this problem with this specific router.
I also had gone through all of the tests of turning off low-power mode, auto-scan, auto-connect to AT&T, etc. but can still have it lock up in the middle of loading a page.
This weekend I can hopefully try it on a few more networks (also a good chance to hit a McDonald's with impunity).
