If this modem has the wifi and such you get to set it all up again.
I recently purchased a new modem to avoid the monthly fee that Time Warner was set to charge us. I had to call TW to activate it and all is well on that score. Yesterday, I went to my seldom used net book that has Win 7, and the network was unattainable. I get a message that its 'limited', but no connection to the internet. I did the Win 7 troubleshooting issue without any success. Is this normal when one replaces a modem?
