I am having a similar problem, NetGear wireless router, using DHCP, routers IP 192.168.5.1, disabled SSID broadcast, and there is a password required.
I can connect to the QU-16, but after 1 minute, my wireless signal turns off (according to my android device). After another minute, the wireless turns back on and then I connect, access the QU-16 and after 1 minute, wireless turns off.
I have been able to properly use this router to access web pages for more than 30 minutes from the android device… but if I access the QU-16, wireless goes off.
Is there a setting in the router that would cause this behavior?
