you are using the password stored in the wireless router ? i know im stating the obvious but ??? what router are you using. if its a d-link (dir-301 ??? ) in the wireless network settings i had to tick 802.11g only mode and save before it would let me see my router and then connect . try to set a wep key for your tablet only i can use up to 4 separate keys also use the lowest security settings first and then when connected try to improve your security level until your at the highest settings you can use.
