there is another tablet out there with "pogo pins" that don't make good electrical contact which messes up the wifi on that tablet. see link below. my le pan II suffered from very slow and flakey wifi until i pressed (squeezed) the two halves of my le pan ii together using my fingers (camera side edge). i think this whole wifi issue with the le pan ii is a hardware issue where there is a bad contact or connection that affects the wifi. "compressing" the le pan ii's two halves near the camera edge fixed the problem for me. the tablet is a joy now - no longer fustrating. the above explanation makes sense and explains why some le pan's are good, others bad (in terms of wifi).
