AT&T tech support confirmed that the Uverse router has no problem. Rebooting or DNS flush with ipconfig didn't help. I also noticed that sometimes websites like Google or Facebook would work while most of other websites won't. Please advise how to solve this problem. Thank you (I am typing on my Macbook).
 
Perhaps the router is only running iPv6? This would explain why you could only access a few iPv6 websites. Also check to see if your router is only on ac or the 5gHz band. A older or cheaper WiFi card on the Windows machines might not like that. Especially the XP ones, why you are even keeping those around with all the security issues I don't know.
