I am using my new iPad with a linksys "G" router and I am impressed at the distance that I have been able to maintain a connection with. Granted I live on the third floor, I was able to maintain a connection and stream videos from you tube at 500 ft. I have not tried it with an "N" router yet. Is the wifi problem specific to "N" connections? Are the other defects you speak off specific to a certain models, or have there been problems reported across all models?
