Hi, I have seen similar problem with PS3, laptops and mobile phones.
It always happens on wireless, and when many clients connected to the router.
If I reset the router (the hole in the bottom), there is no problem connecting to the router for any of these devices. But if I connect at lot of other devices first, there is problems connection to wireless for new devices.
On the laptop I can see it connects to the router, but doesnt get the right IP, but assigns a dummy IP, telling that it didnt get IP from DHCP server.
As I see it, the router has problem with DHCP server on wireless side, when many devices has allready been asigned an IP.
In my case, I have around 15 devices connected, mix of wired and 2.4Gwireless and 5G wireless. All are 802.11n. Firmware is 1.07. And DHCP range covers 80 ip's, .20 to .100. Have also tried default settings, and range from .10 to .200. Same thing.
If i default the router, and first connect all my wireless devices, and then the wired ones, I can have all devices running on the router. But if I then have a guest that would like to use the wireless network, this happens again. He can see the router, and try to connect, but will not get an ip from the routers dhcp server.
