After about 30-45 minutes I have to reset the router or renew the Ip as I cannot get any new connects to the internet. Existing connects are ok. This is across several computers all running Win 7
I’m experiencing a similar problem with my net n900 central router as well. You may try to disable DNS proxy. For me was DNS causing internet to hang up. I verified the connection by attaching the modem directly to my laptop and it was fine. Definitely it was the router. After rebooting it last for a couple of hours. I have to restart the router almost every day to get internet going again.
Do you know when they are going to release a new firmware? I have a feeling that they completely forgot about this router.
