I noticed that AT&T released some firmware with IPv6 support back in May for their 3801HGV (and related) gateways. To try this out, I factory-reset my 3801HGV (still on version 6.9) and it installed the 6.11 firmware about 10 minutes later. I then used the obscure page at https://esupport.att3.2wire.com/online-tool/compat-index.jsp to request an IPv6 address ("wait 48 hours" it said) and got a routable IPv6 address in just a few minutes. All for naught, though. With IPv6 enabled, the 3801HGV crashed and rebooted about once an hour. After unchecking "IPv6 LAN Enabled" in http://192.168.1.254/xslt?PAGE=C_2_6 everything went back to normal. If anyone from AT&T is listening, I'm happy to help diagnose your firmware problems. Ivan
