How to connect to ISP?

[mahesh]

I cannot connect to the internet. In Windows I use: Set up a new connection or network/ Set up a broadband or dial-up connection to the internet/ Set up a new connection anyway/ create a new connection/How do you want to connect? – Broadband (PPPoE)/ User name (name your isp gave you) and password (password your ISP gave you). I have a wired lan connection to a switch then to a modem. No router. I have looked at previous posts and one recommendation was to use the network manager but I cannot find it. Any tips please?
