@bkai,

Have you had the chance to go into your system logs in the WebUI to see if there are any errors being thrown when the disconnects occur?

When the dropout occurs, it would be helpful to know what side of the connection is causing this. For multiple devices to have dropouts at the same time, I would expect to see an issue with the WAN connection or the negotiation between the modem and router. If the behavior is limited to wireless devices, I would make sure that the router is continuing to broadcast the SSID throughout the drop, or see if the entire wireless network drops out for a second.

Is there a reason that you have attempted so many changes to the power supply given to the router? Is there an indicator that the router is underpowered or restarting each time?

  @bkai,

I think that you can eliminate the power source as an issue as this is rarely the case, especially if the router is operating normally. I would double check that you go through the different filters for the logs, it is somewhat hard to believe that no messages would be given for behavior like this, but it is possible.

If you are using a wireless device when the connection drops, does the device disconnect from the network or only lose a connection to the internet?

If you have a device that you know will drop the connection each time, you may try to set an IP reservation for the device. This way we may get a clue if it an addressing issue.

You may potentially want to look at the logs for your modem or get in contact with your ISP to ensure that the WAN connection is not dropping.

Lastly, you may want to look into resetting and reconfiguring the network, as this would erase any cached or incompatible settings that are causing the issue, such as a WAN IP change.
