Fix For – No Internet Access IP Problem
There is no name to this bug so we have code named it “blizzard” to provide help and support to our customers that have purchased computers and call for support. “Blizzard” is just a unique keyword that will help you find this help file when searching our site. (and it’s nearly Christmas so it fits). I haven’t used the word “blizzard” in any other Knowledge Base post so there will be no confusion, if I have directed you here on the phone, you are on the right page.
We have been inundated with a bug that causes IP problems. This glitch will prevent you from accessing the internet and display some kind of “Page Cannot Be Reached” problem quoting an IP configuration issue.
We started to see the problem a couple of weeks ago with what we thought were isolated cases. The past day or two we have been inundated with calls and computers being brought in to have this repaired.
The cause of this bug is yet unconfirmed. There is suggestion that it has been caused by a Windows Update. I don’t agree with this because I have seen the problem on machines with a fresh install of Windows.
We refer to this as a bug, which is a glitch – this is not a virus. Do not panic.
There doesn’t appear to be a pattern yet as the computers I have seen affected are different models and makes, with various different brands of network adapters.
This issue is not just on wireless computers, but also on LAN (hard wire) connected machines.
My theory is that this relates to the big switch over from IPv4 to IPv6.
This bug is not local to our area, there has been discussion on forums from computer technicians all over the country today about this problem.

If this resolves the issue – you do not have to do anything else.
