DNS Server not available ?

Hello, 

 

        I just wanted to mention that as of the last 3-4 weeks I have had trouble accessing the internet from my computer when I have turned it on first thing in the morning. I turn on the Superhub, and after the computer has loaded completely, I try to open Internet Explorer. The signal bars in the bottom right hand corner say that I have full connection and internet access, yet I am still unable to access the internet and the same message appears over and over again. The message says that the DNS Server could not be located/found and recommends options I should try. I have tried all of the options at my disposal (nothing has worked, and each time I need to reboot both the Superhub and my Computer several times each morning) and the last resort tells me to contact my ISP.  

 

If the Virgin Media Forum team could give me any advice, a fix for this, or arrange for a Technician to come out if needed I would be very grateful ! 

 

Many thanks to the Forum team, appreciate the quick responses and answers. 

 

Thanks, Richard.

Re: DNS Server not available ?

if you do a wired connection the hub and disconnect from the wifi connection can you then get online?

what version of windows you running eg xp/vista/7?

when was the last time you could get online?

 

and to check the hub itself

Visit http://192.168.0.1 username admin password changeme if you then click on advanced settings, and choose connection and copy and paste all details

Re: DNS Server not available ?

Hi paultechy, 

 

                   I appreciate the quick reply in trying to resolve this issue. The Superhub is hardwired into the back of my computer, and after rebooting the computer several times it finally allows access even though as I mentioned it's been telling me the whole time that I have internet access. The computer is running on Windows Vista, and I am able to get online now, but can almost guarantee the next time I have to reboot the computer the issue will arise again ! 

 

Here is the readout from my Superhub: 

  

Many Thanks, Richard

Re: DNS Server not available ?

Hi Richard_SFC,

 

The local signal levels you have posted are fine. Have you tried a 2nd PC hard-wired to the super-hub to see if you can replicate the problem? You state that you switch your super-hub on of a morning. What happens if you leave the super-hub on overnight and then just boot the PC in the morning? Does it connect first time?

 

Regards,
