I purchased the iEDGE flash card (flashed to 1.9 firmware) for my recently bought DSi XL. It's a fantastic card just like my old EDGE flash card but I'm having major wifi problems. I can get on the internet fine (through my Billion 7800N router) but I can't connect to games like Tetris DS or Tetris Terror Instinct homebrew... I'm getting really bad withdrawl symptoms not connecting to the internet ranking on Tetris Terror Instinct! Can anyone help me with my bizarre wifi problem? Many thanks in advance.
