If none of the articles helped an you are still recieving the error 721 code, then try the following to resolve your issue:

  2. Double click on the green triangle and a pop-up window will appear. Check to see that DSL Status: OPERATIONAL. Click for sample screenshot
  3. Press the Alt + D key at the same time, this will pop-up a new window, titled Administrative. There will be four tabs, click the second Tab which is titled CONFIG. Click for sample screenshot

    Tiscali/Talk Talk are notorious for providing a bad service. I was with them for 2 years and finally went with another provider, due to the high number of times I was having trouble connecting to the Internet (my latest provider I have had no connection issues or speed issues as yet)

    The only thing I can recommend is contacting support and be prepared for repeating the same task over and over again, try not to be fobbed of and keep at them.

    I realise their support is quite bad, so if you want to leave it as a last resort, you can try following the guide at: http://www.pcadvisor.co.uk/forums/index.cfm?action=showthread&threadid=292755&forumid=1

    I am sorry I can’t be of more help.
