I have had my N600 for a week now and I keep getting a problem. Every morning when I wake up my router is broadcasting a signal but I can NOT connect any of my wireless devices to it.
When I go into the device and choose my network, each device says that the password has been saved and I get no further.
However when I re-boot the router, then I get wifi straight away with all my devices.
My little network consists of
NAS iomega ix-200 - wired to router
PC (Win7) - wired to router
Laptop (Win7) - wireless
Tablet Asus - wireless
Other little devices such as Raspberry Pi - wireless
