Unable to connect via IPhone

I have 2 cameras. One I have no probs with but the other one at our summer house is impossible to connect to. Bought a new router to accommodate wifi, couldnt get it to connect unless plugged in to router, infrared is useless. But biggest thing is it blinks when u connect so if youre using it as a cam to see if any probs the other side has advanced notice :( defeats the purpose
