It works better than a PC in the same room. There are 2 walls inbetween the router and the Wii.
-> Here's a tip. My router didn't work with the PC in the same room out of the box. A new version of firmware saved it from being returned. What others also discover is that while one PC may work fine, their new PC won't connect. Again it can be the firmware in the router.

So I finally bought a Wii and was a little disappointed that the wireless card sucks so bad. It is a mere 3 feet away from my wireless router with a receiver between the two. I was able to run a successful connection to my network but when I wanted to connect to the internet the signal was too weak. I powered down my receiver to see if there was any interference from it but no dice.
Nintendo in all its wisdom decided to not give me a wired option to go directly from the Wii to the router (unless there is some accessory for it) and made their internal wireless card so crappy that it cannot have a strong signal from a router 3 feet away. Way to go Nintendo, now give me a way to hard wire my Wii to my router.
