One possible cause may be torrents. I haven't heard of any problems specifically with the 2wire, but I have heard of other routers crashing due to too many torrent connections.
Some questions to help isolate the problem:
Do you use torrents?
If so, which program?
Do you limit the number of connections?
Do the crashes coincide with heavy torrent activity?
When the wired PC loses connection, can the Blu-ray still connect?
Do you lose the TV streams when the wired PC hangs?
