Vista - Connect to the network manually 2

I had to do this because i couldn't view 1st, 3rd to 4th page on my thread. Any way let me mention my problem again. my problem is that i always connect to the internet automatically whenever i plug in the ethernet cable from my adsl 2/2+ modem to my computer. it doesn't request for a id and password. i have no problem setting the wireless for requesting a wep every time but the lan connection is the problem. please do not give me complicated explanations because of the com fault i mentioned before. if you have any solutions , just post me the steps and i will try. i am using a modem under the brand Riger and it comes free with my ISP package, on the modem it states that it is a DB108-WL model and it is a adsl 2/2+. I tried going to 168.192.1.1 but it doesn't gives me an option to configure the settings. any suggestions? i have plenty of time.
