My cable company recently upgraded its modems (oh, the fun...not!) There are 3 computers in my home, one which is connected directly to the modem, and 2 on wireless connections. The other wireless computer is maintaining an Internet connection without any problems, mine isn't. When it tries to automatically sign on to the network, the wireless connection gets as far as "Acquiring network address", then stops. However, it will successfully connect to another network that is within range, so I'm pretty sure my wireless adapter isn't bad. Resetting the modem isn't producing any results. Mine is a Dell Inspiron 2200 running Windows XP SP3. I'm using the wireless adapter that came installed with the computer, my anti-virus (Norton 2012) is up to date, and Windows Firewall is turned on. According to the cable company, my OS is supposed to be compatible with the new modem. The modem is an Arris Telephony Gateway. Any ideas on possible causes and solutions?
