Give it a chance. You will love it and besides - you really needed an upgraded modem anyway since most stuff is going wireless.
My husband was very anti - new technology. He went out of town... While he was gone I set up a wireless network with his TV and Wii on it, the bedroom TV on it, my Blackberry Playbook and the computer on it, and signed up for 30 days of free Netflix. He loves it! It will be a year in October and we still have the Netflix. He is a B movie fan. Who knew! LoL!
I'd be more frustrated having to wait on the modem!
