The higher elevated the better. In the three-story house situation, I definitely agree with your statement regarding the router being placed on floor two. As a general rule no other electrical or wireless equipment should be placed within three feet of the wireless gateway. Do not set wireless gateways on speakers due to electromagnetic interference regardless if there is power to the speaker or not. To ensure you have the latest firmware you can check in the router settings page. You can also call tech support so they can verify you have the latest firmware updateand that your router settings are configured properly to work with the update. The "sleep"/signal drop/intermittent connectivity issue has been fixed with the latest version. There is an unexplained DNS timeout that seems to affect Windows 8/8.1 with this model wireless gateway. It is not happening across all wireless adapters. The current workaround is a reconfiguration of DNS. If this is affecting you please note your wireless adapter model. Any reconfiguration should be done by a qualified tier support technician over the phone or an on-site service technician.
