I have a wGR614 v7 router set up and it works fine with both wired and wireless devices. However, every 3 days or so, if I try to connect to it with a wireless device, it will try to obtain an IP address and fail until I log into the router config and reapply settings (with no changes made). I assume this recycles the signal. Why do i have to do this every 3 days or so? is there a timeout setting of some sort? The wired devices continue to work without issue.
