I was wondering if someone can help me. For whatever reason I am unable to make a connection with friends with Pokemon White. I get the error code 86420. I use a DSi and my router is a Belkin. I tried disabling the router's firewall but that didn't work. Does anyone have any suggestions? Thanks
Okay, this is how you can fix your problem:
Step 1-Use this step to find your IP Address. If you know your IP Address, skip to step 3. If you have a Windows PC, click on the bottom left (or start) and click on Run. Once you're in run, type in cmd and press enter to enter. You should see a black box come up. If you have a mac, search 'How to find Command prompt on mac' on the web, or try anything else.
Step 2-In this black box (called the command prompt) type in ipconfig/all and press enter. Lots of text should come up. Scroll your way to 'Default Gateway' and minimize the black box or write down the numbers that are to the right of Default Gateway. The numbers here are the IP Address.
Step 3-Open up your browser. DON'T use the search bar on your browser like Google, Firefox, Opera, etc. Use the search bar on top of the computer screen. Type in the IP Address with the dots in their order, eg: 192.168.0.1 and press enter.
Step 4-After you hit Enter, you should see a website which looks like you have to log into it. Where it says user, type in Admin and type in Password for the password and press enter.
Step 5-You should now be in a website where you can configure your Internet settings. From here, click on 'Firewall rules' to the left of the website.You should be in some kind of Port Fowarding area. From here, you will see see something that says 'Add custom rules'. Click in the box that says name and type in DS or DSi. Now click in the box next to it that says Start Port. In here, type in 1. In the box next to it called 'End Port', type in 65535. Now in the box next to it that says Protocol, click in it and select 'Both'. Finally, type in the last part of your IP Address in the last box. Under all of this, there will be the options Add, Delete and Reset. Click Add.
Step 5- Go on your DS and see if it works. If not, call the Nintendo Support centre.
Hope this helps!
