I have had this problem most of this month!! Here are the case numbers from having to call support to no avail to straighten the problem out.I have Gen 4 modem is HT1100! Case numbers I have are 47156914 on 4/11/15, 47165480 on 4/12/15, 47181619 on 4/13/15, 47183648 on4/14/15, 47200704 on 4/14/15, 47312526 on 4/21/15 and still have not gotten the DSN server errors fixed! Here is what I have done rebooted computer several times, changed dns server to the 184.108.40.206 and 220.127.116.11, cleared cache, unplugged evrything from wall,done flush DNS, cleared cache and cookies. Well after all this support told me my computer was messed up and refered me to hometec which I have to pay $9.99 a moth for 12 months until paid! So hometec said they could not find anything wrong with my computer, and now I'm still having the same issues and out of money to find out it wasn't my computer. Someone needs to fix this I pay to much money to not be able to use the internet..
I was looking over your direct connection to the modem and your ipconfig /all results and saw that all the IP address listings are IPv6, not IPv4. I believe we should really look into your settings and do testing over the phone. Can we have someone call you from our corporate office on Monday? You let us know the best time.
Also, over the weekend, if you have time.
Try to access a website by its IP address. In command prompt, type "nslookup www.facebook.com"; or any website, and type the IP address that comes up in your web browser's address bar. If this connects you, we may need to help you make some adjustments.
Im thinking that Norton antivirus has changed this last configuration to push all web traffic through Nortons DNS server, there are several antivirus programs that do this and when their DNS server is down you get basically the same as your seeing
I have a update to share! I figured out the problem with the DNS errors, It was my router that was causing the problem and I have returned It! I went ahead and bought me a new computer and everything is doing fine now. I want to thank everyone that tried to help me get the problem resolved, you guy's went above and beyond to help me and I want to thank you! Have a great rest of the week..
I think I speak for everyone when I say that we are SO happy you got this fixed! We really broke our heads over this one 🙂 Please do come back to us if you need anything, or just want to offer up some of your own advice!
