Been having a lot of WiFi issues with my iPad. It's not a connection problem -- just overall signal strength compared to what I am getting on my other Apple devices. Yes, I did all the router fixes suggested. My router is not dual-band. Does only "G" Thought I would return my 16GB to the Apple Store let them know the issue and upgrade to the 32GB. Perhaps, just by chance, the 32GB will have better WiFi range on it. All this within 7 days of my original purchase. Will Apple store just do the upgrade with no restocking fee? Thanks for the help.
