Hi. I just got the 628, almost everything working fine.  I can surf, VOIP, connect Wii wirelessly, etc.  The only thing is, certain web pages won't load.  These include www.signonsandiego.com, www.washingtonpost.com, myspace and a few others.  99% of all other web pages load no problem, quickly and completely.  This is true whether I connect wired or wirelessly.
For the pages that don't load, I just get a blank browser screen. The status bar at the bottom says "Waiting for <webpage>" or it might say "Transferring data from <webpage>" but nothing loads. Generally, they don't even timeout; they just try endlessly to load which seems weird (at least for 5 minutes, after which I generally close the window.)
I have a MacBook with OSX 10.5.8 and PC with XP on the LAN.  The Mac has Firefox and Safari; the PC has IE and FF.  All have the latest s/w updates.  I have the same problem with the same sites on both computers on all 4 browsers.  Thus, it must be a router problem.  It cannot be a browser or machine-specific problem. Occasionally, I can tap into my neighbor's unsecured wifi, and when I do I can surf these websites.  So it's not a wifi problem.
My 628 has the latest firmware.  Is there some firewall setting that might be blocking some element that these websites have in common?  I don't know much about firewalls so I don't worry about "talking down" to me about it.  I read the help files and nothing really jumped out at me.  Thanks!
