It's really hard understanding what your trying to say with grammar like that. You might want to type out full and complete sentences.
Anyway try these steps first.
1) Set your Wii with a static IP address using OpenDNS and setting your MTU to auto (zero).
2) Update your wireless router with the latest firmware if available.
3) Set your wireless channel to either 6 or 11.
4) Turn on DMZ and input your Wii static IP address in the DMZ.
