Greetings friends, stay a while and listen , I tried to play Mario Kart and Chocobo Tales on my Nintendo DS R4IIIsdhc card without any success. I tried EVERYTHING, and yet cant get it to work. I am using adsl wireless router and i have no problems connecting to it. I've turned off its firewall and put WEP security. So, the DS can see my access point and actually can connect to nintendo WFC but what happens? When i try to connect to my girlfriend (search for friend using friend code) it searches for like 2-3 mins until it disconnects me from server with an 86420 error at the same time as it disconnects her. I have tried port forwarding - forwarded 29901 port in my router (intracom JetSpeed IAD) and put address 192.168.1.13 or example for it and then set that static ip on my ds and tried if the connection works. I can connect to nintendo wfc but not to a friend. I have also tried in both situations t connect to a random person on worldwide and cannot find anyone cannot connect to anyone and after several mins same error shows. Also i tried telling girlfriend to forward port on her router and she did but it didn't help. I've searched EVERYWHERE for an answer, but i just cannot make this work. If you have ANY suggestions or if you think i'm doing something wrong here, please tell me, i'd be VERY delighted.
