what do you do if your Wii finds access points,but when you test the connection it always fails?

its either you have a bad connection

or

your inputting the wrong password if its locked

if you have a bad connection try getting the router and the wii as close as possible.

if you are inputting the wrong password, too bad.

your neighbor doesnt like to share

Do you employ instantaneous or under pressure out? and do an replace on your wii attempt Wii putting>internet>gadget replace or maybe its around wii settings...you could continuously attempt google :) and stable success!
