Adsl with netgearRouter help

Good day ppl…….I have a PC that refuses to connect to the internet via a netgear router. I have tested the pc and settings at my work place and it connects with ease, take it to another premises with ADSL and try and connect via a netgear router, NO connection. I have changed the router, tested the line, changed cables and reset the password and I still dont have connectivity. I can ping the router and logon to it as well. Can anyone assist?
