Can't connect to wifi

I posted this on Serebii but no one knew what the problem was, so I'll try posting it here.

Whenever I try connecting to wifi I get the error code 61010. I've tried entering it on the nintendo wifi website but the UK one doesn't work (Nothing happens when you put in the error code) and the US website says the error code doesn't exist! Does anyone know why this is happening and how I can fix it?

Hmm... exactly HOW do you connect? I use a WEP key (btw I'm english too). This is your Wii, right? Anyways, if you are using a WEP key you may have an incompatible router (happened with my bro's 360), they have (or had) a large list on the nintendo wifi site.

you should go onto wifi.com and check youve got a compatible router
