Just installed a belkin n600 wifi extender (model 9F9K1106). I used a windows 7 notebook for the simple setup and it appears to work fine. I have a Comcast SMC D3 modem/wifi/router as my main wifi. The trouble is that my iPad, iPhone, linux notebook, and android phone see the extender and connect ok but cannot access the internet. It appears to only work with windows. Any suggestions?
