Can't connect to internet ttill 15 min after startup
I have a problem that seems to be getting worse. I am running Windows 7
Home Premium. I have a wired Ethernet network in the house and connect to the internet and the home network via an AT&T Modem/Router using ATT U-Verse. (U-Verse in itself may be the problem). I cannot connect to the internet after a Startup or Startover until 15 minutes after either. This started out at about 5 minutes and has slowly taken longer and I just timed it at 15 minutes. This is on my primary computer. I have a secondary computer also connected to the internet through the same modem/router and it doesn't have the delay. It connects to the internet quickly. this computer is running Vista Home Premium. I have turned off Norton Internet Security, thinking it might be the problem but it still exists with it off. I had an earlier problem with the IPV6 Protocol and that took a while to get rid of. It turned off IPv6 and had to remove 435 entries that had somehow got into the system. Does anyone know of a requirement to have IPv6 working in Windows 7. I know it is required if you use Homegroup, but I don't use that because my second computer has Vista and Homegroup won't work unless all computers are on Windows 7. I don't know if I have made myself clear, but does anyone have an idea about where to look to see what is happening that causes this delay. I use 'Process Explorer', but I don't see anything out of place there. Thanks for any help Don D. |

The Internet isn't something you connect to, it's something you use to connect to other hosts on the Internet. How are you determining that you don't have a working Internet connection for 15 minutes? My guess is that your attempt to repair an earlier IPv6 issue has left you with a system that is confused about how it should network. It might be waiting for something to time out, and only then does it attempt to use IPv4. You might remove and reinstall the Windows Networking components. While IPv6 shouldn't be needed, if it was removed improperly it could be causing problems. Reinstall it and leave it installed (but unused). The good news is that 15 minutes is more than enough time to do some troubleshooting. During the 15-minute blackout, open a Command Prompt and if you use DHCP then run "ipconfig /all" (no quotes) to see if your computer is waiting for an IP address to be assigned. If all of the IP info is assigned and correct, ping the router and the second computer. If you have connectivity to them but not to the Internet the problem is likely with the router. Ping an IP address on the Internet to see if you have IP connectivity. If pinging an IP address works but accessing your mail server or a web site by name doesn't work, then it's a DNS issue. This just scratches the surface but will hopefully get you started. -- Char Jackson |

Nope, I can't. It is just one box, a modem/router. It is a 2Wire i38HG. |

The Internet isn't something you connect to, it's something you use to connect to other hosts on the Internet. How are you determining that you don't have a working Internet connection for 15 minutes? OK, I'm using a generic term meaning that I can't connect to any host on the internet. When I look at Network and Sharing Center on Control Panel, I see a Red X over the Network icon indicating that I'm not 'connected to the Internet'. My guess is that your attempt to repair an earlier IPv6 issue has left you with a system that is confused about how it should network. It might be waiting for something to time out, and only then does it attempt to use IPv4. You might remove and reinstall the Windows Networking components. While IPv6 shouldn't be needed, if it was removed improperly it could be causing problems. Reinstall it and leave it installed (but unused). It is waiting for a 'Toredo Tunneling Pseudo-Interface' to connect. I have determined this be doing an ipconfig and ipconfig /all immediately after I start up and then again when the 'RED X" goes away. (meaning to me I am connected to the Internet). This appears to isolate the problem to IPv6, because the ipconfig after the x disappears, shows that it is using an IPv6 address. This is strange because I uninstalled the IPve adapter after an earlier problem. I had been told on another forum that this wouldn't bother me as long as I wasn't using Homegroup for my home network I can't use Homegroup because my 2nd computer is using Vista. The good news is that 15 minutes is more than enough time to do some troubleshooting.

This just scratches the surface but will hopefully get you started. -- Char Jackson After all this, what is the Microsoft Teredo Tunneling Adapter and do I need it. I will do some more research, but do you have a quick answer. Also what else would use IPv6 other than Homegroup in a normal home environment. Don D |

I disabled another entry in the Device Manager for Networks. A hidden entry for the Microsoft Toredo Tunneling Pseudo-adapter. After another startover, the time between starting up and connecting to the internet was only about 2 minutes, which sounds almost reasonable. It did have an entry in the ipconfig /all for the adapter but no 'Connection specific DNS suffix'. Again, it showed an IPv6 address. I will do more research but I still am not sure what effect my disabling this adapter will have. Thanks |

I tried the 'ipv6 uninstall' from the cmd prompt and it tells me 'ipv6 is not recognized as an internal or external command, operable program or batch file.' I am assuming that this message is because ipv6 was already uninstalled? Anyway, everything seems to work and I connect to the internet immediately after startup or startover. The speed of my connection is fine and it looks as if ipv6 is not actually necessary for any program I run or web site I use.. Don D |
