I have to 2nd USOGoose's verdic on the Netgear 7550. Just received mine last night and lost network to every computer 30minutes after install. The computer connected via ethernet had internet running, no other computers could reconnect to the Netgear. Could not reset the modem remotely, had to physically go the to model and reset it. Sucks late at night when everyone is in bed and you need to send a quick email from your laptop or tablet. Considering reinstalling my old 2wire.
Good, then I know it's not my line, as AT&T thinks it still is, despite replacing the 7550 3 times. And yet the 755o is still on their site yet they pulle the 4111n.
