I subscribed to Verizon FiOS this January and have had problems ever since with the Actiontec broadband wireless router locking up every few days. The easiest way to make it lock up is to download movie trailers. http://www.apple.com/trailers/disney/underdog/large.html will lock up the router in seconds. Video iChat conversations will lock up the router in a few minutes. The problem only occurs from my Macs whether connecting wirelessly or via ethernet. My Windows computers download videos with no apparent ill effects. I've had the Actiontec router swapped out twice, so it doesn't seem like a hardware problem.

Verizon customer service says it is a Mac problem. I haven't figured out how to contact Apple, yet.
