I need some help. Recently I found out that something has changed on my TF 300. I get all wi fi in reach and have no problem to use most of them but the problem starts when for example I am using a wi fi repeater the pad will have the full signal but is resulting in trying to obtain ip address and then saying authenticating etc but never connects. I did start it from scratch and put in the secure password again and again several times while even re booting a few times also but still not connecting. This same problem I have on 3 repeating systems I normally use at different households. Please also note that I do not have this problem on the smart phones or laptops I use. thanks for any advice anyone can give me.
