I would also like to know what is the difference between the 2 routers. Especially concerning wireless. I had no problems with the Mega 100WR2, 99.70.1 and my wireless card, Netgear WG311T. Now packets keep timing out a lot. Signal is 60%, which should be good enough. When I tested with my friend's Linksys, not sure which one, but it worked fine aswell. Need to know what changes were made to the wireless config between the 100WR2 and 105WR.
