Wireless Internet stops working until reconnect to WiFi Router

Question

Sometimes, like once per 20 minutes, internet suddenly stops working on my Mac. If I turn AirPort off and then on, it becomes working again.

With the same frequency, internet stops working on my iPod touch. If I turn wi-fi off and then on (or airplane mode on and then off) it becomes working again too.

I think it has something to do with my router preferences. But I have no idea where to look, please give me a clue!

My router is Asus GT-32, Firmware Version: 2.0.0.5

Answer 1

It might be the setting of the router concerning the DHCP lease : The amount of time that the DHCP server grants to the DHCP client permission to use a particular IP address. In this case it would make more sense to change it to not expire or extend the lease period.

If the lease expires, there's still a good chance that the router will assign you the same IP again. The lease expiration itself may disconnect your device, depending on the router's behavior and/or settings.

So go into your router's settings screen and check DHCP lease time.

There are newer firmware versions for the RT-G32 available from here. It might be worthwhile to upgrade (very carefully). Pay attention to the version you download, as it seems that there exists also an RT-G32 Rev.B1, which is probably not your router.
