hello and thank you for contacting me i have one question have you tried to plug your ethernet cable in to your router and tablet first before taking those steps. i own the android mid 7 inch tablet with froyo 2.2 and i am having trouble with my wifi connection and the only way i can connect at the moment is through ethernet by doing what i asked in the beginning. i really can't provide any info about static ip and the other things you spoke of but i hope what i said in the beginning works for you so if you changed stuff put it back and just do the connection first.
