When the latest update to the 3DS came I went ahead and downloaded it with no problems and went ahead and tried the new streetpass stuff (Incidentally it looks great). But now my 3DS can't access my router anymore. I've had this 3DS for about four months now and since Day 1 internet access with this router has been no issue, it has served as my main router and hasn't had a single problem with my 3DS before this. I download this latest update and now I have no internet access anymore.
The error code I keep receiving is: 003-1101 or in other words, unable to connect to the access point. I know my internet works fine since every other device, including the laptop I'm typing this on, run just fine with no internet troubles. I've already tried turning the system on/off, resetting the wireless via the little switch, resetting the router, and re-entering the settings multiple times to see if that would help. None of it did. I keep getting the same error. Other than this though my 3DS seems to run just fine.
