I have a Netgear modem/router hooked up at my house, and a USB Wi-Fi Connector too, and this combo worked to play Strikers, but, ever since Brawl released I haven't been able to get any kind of connection.
I went online and eventually figured out it's because my Netgear has an SPI Firewall or some crap and Nintendo's servers hate SPI firewalls. Since I can't turn it off I have to get a new modem/router.
So can anyone recommend a modem/router that works great with a Wii? I have a 150ish American dollar budget for the thing, as I'm tired of this crap not working and well, I just can't spend 200 bucks on a modem/router.

Here's a list of routers that are incompatible with the Wii, apparently!

Belkin
F5D6231-4 vers. 1000
F5D7230-4 vers. 4000

Linksys
WCG200 ver. 2
WCG200-CC
WCG200-CC ver. 2

Netgear
CG814W
CG814WG ver .2
CG814WG

RCA
DCW725

Bummer, I have a Netgear CG814WG ver 2! Any advice?

Most routers should work fine. It's the rare one that doesn't. You just got unlucky.

I have a Buffalo AirStation G54. It works great. They don't make this model anymore though. I highly recommend Buffalo routers though.
