When my laptop starts it usually has internet connection but today it doesnt work and now i have to use my bros computer. I check my network connections and one of my networks was deleted all i have now is the wireless network which is automatically there. I have a Siemens 4400 modem and it came with a disk i followed the steps and then when it went to the detecting modem it had a error saying couldnt establish a connection with the modem.

anyone help please maybe just a quick guide
