Is this issue symptomatic of the device sleeping? The S3 has an optipn in the settings to sleep the wifi connection if the screen times out.
You could try toggling airplane mode on then off. That used to sort some APN issues on 3/4G
You might also want to check the channel your routers broadcasting on, as it may be a cluttered channel. Also check that your not using WPA encryption, but WPA2 & PSK for better compatability and speed.
