The router/modem works fine when I am accessing the internet. If I don't access the internet for about 1/2 hour or so, the router acts as if its sleeping and I cannot access the internet. (my computer is not on power save or otherwise dormant during this time) Also, all the lights on the router are still green.
The network map on my computer shows connection between computer and router is enabled, but shows that the conection between router and the internet is disabled.
I called Windstream tech help, and they sent a signal to the router and connection was restored. I can also restore connection by power off then power on the router.
This has occurred several times and I am wondering if the router has a "sleep" option that can be reconfigured.
