I have a Belkin wireless router. I also have a modem inside my mom's closet that connects each room in my house that has an ethernet port to high-speed internet. The router is behind 4 thick walls with a cordless phone in the living room (I don't think it interferes with the router). I have no where else to put the router closer to the Wii. When I play SSBB online, the game lags into the deepest freeze of it's life.
My local GameStop has a Wii LAN Adapter in stock for $30. If I got this, do you think I will receive less lag and better time playing online? It would be a wired connection.
