Hello,
I know that problem come up almost every day but after looking all over last night, i still can't connect to internet with my wii

I'am French playing in Thailand so not that easy to get help here... I have a SMC router.
I go to the router configuration 192.168.2.1, i disabled everything like firewall WEP...
Then i chose to go for the static adress,then wrote IP adress and the DNS manually like it said on my router menu but still doesn't work... MTU is set at 1500 on my wii. I also set the channel to 1 like it said everywhere. And another problem, i can't use ipconfig/all, the ms window close after few seconds when i open it

That's my menu :
INTERNET
ADSL: CONNECTED
WAN IP: 61.7.138.79
Subnet Mask: 255.0.0.0
Gateway: 61.7.138.1
Primary DNS: 202.129.27.135
Secondary DNS: 202.47.249.4
GATEWAY
IP Address: 192.168.2.1
Subnet Mask: 255.255.255.0
DHCP Server: Enabled
Firewall: Enabled
UPnP: Enabled
Wireless: Enabled
All the IP changed from last night so i don't really understand

I'am not a pro in computer so if you can try to explain me like easy easy ^^
And i don't really get what i need to put in "Default Router".
Please help me !
PS: Sorry for my english so poor...
