Thanks for the advice. I will try that over the weekend

Hi.thanks for your reply. I am pretty sure it is adsl line and my ISP is Vodafone. I have unplugged and hard reset the router but to no avail Kevin_Z wrote @Loz Who is your internet service provider?...

I purchased a new tp link adsl 2+ router / Modem. My problem after setup is the adsl light just keeps flashing and not staying on solid as it should. Put my ISP Vodafone router back and that works...
