Hi, I have a Linksys WRT300n router and have had no trouble setting it up for my wii.
I haven't played in a while and tried to play BWii but it said I had a connection problem. I have gone through my settings in both the router and Wii, but I just cant figure out what the problem is.
I don't have security on my router, but I do have a wireless MAC filter because that is plenty of security for where I am at. For my Wii, I have an IP address reserved for it in the DHCP set up (as I have for my laptop & PSP as well). The MAC addresses match in the filter.
I have tried manually inputing the information in the Wii, even though I shouldn't have to. I ran a diagnostic on my router when my Wii was connected and it found it and displayed the correct information. I have disabled the SPI firewall because I read that could be the problem. It didn't work so I re-enabled it. I just can't think of what else it could be.
Earlier today I could use the Internet browser and was on the Voting channel, also the Weather and News channels updated. I haven't been able to connect games or go on the Shop channel at all.
