i used a wireless modem to provide internet access for my K4(untouch), and at first time it worked normally. But just after a crush(cause to restart) to my K4, i could not find the wifi name(SSD) i used last time anymore, while other spot names remains available. I've tried to input the spot information(SSD & password) manually but it didn't work.Could anybody please tell me how to solve the problem? thx a lot!
