I have this old DSL 502T Dlink modem router(wired). I have been using this for many years without any issues.
Recently though, there is issue connecting to the Internet (WAN side). It takes many attempts (restarts of modem) to connect to the internet for the first time, that is when my PC and Modem are started. It takes minimum 3-4 restarts of modem to get an internet connection working.
I am completely new in Ubuntu. So please explain everything as a newbie friendly tone. I have Ubuntu 13.04 LTS on my machine with a Windows 7 as dual booting. I rarely use Ubuntu. But now planning to use it regularly and want to be familiar with it. The first step is setting up internet in Ubuntu. Fortunately I was able to setup my CDMA modem with Ubuntu.
