I have a WRT54G Linksys wireless router..

Standard g router, when I start up my Wii I can see wireless networks all around me ( apartment type complex ) and I connect to my router... It begins the download then about a quarter to half of the way through it stops and gives an error about losing connection... Any sugggestions? I could hardwire it to the Wii to get the updates but am I missing something?

I know someone said something about some Wii's having problems an not being able to work properly, is this the case for me?
