wireless Internet goes off then on again randomly

I have "Option Globesurfer ii 7.2" router attached by cat5 cable with "Airlive WL-5470POE", I configured airlive unit to be AP, but i have a problem that the internet goes off and on randomly.
when the internet goes off and tried to go to router page ( i was prompted to give username and password, but when the page is loaded previously and tried to refresh it I have "404 not found" page.
if I press "back" on the browser and refresh again some times the page refreshes (and in this case there's internet), or it will return "404 not found" (no internet connectivity).

Have any ideas, thanks in advance.
