Roku works perfectly once I make an internet connection, but it won't connect unless I power cycle my modem/router and the player. Occurs after Roku has been off a couple hours and occurs with both a wired or wireless connection. Power cycling my actiontec dsl modem/router and Roku always bring it back up and it works fine. Four call to support yielded people eager to help, but no permanent solution.
I have used a vast variety of wired and wireless devices with my actiontec modem (GT704-WG) without any problem, so I am inclined to believe my issue is roku specific. (I noticed another user with this problem said he got his player from Amazon, which I did as well. Maybe the batch Amazon is selling is defective.) For what it is worth, here's my wired connection: Actiontec is connected directly via ethernet cable to a netgear powerline adapter; the netgear adapter sends a wired signal via my house wiring to another netgear adapter at a different location; the latter adapter is connected via ethernet cable to my Roku player.
My next step will be to return my Roku player to Amazon and buy a blueray player with netflix capability.
I am not familiar with your particular modem, so I don't know if you need to login to connect to the internet, but if you can, try connecting the Roku DVP directly to the modem and see if you can connect that way. It would be helpful to know if you have had this device running as expected previously. I take it that the Actiontec is a router as well as a modem? I would try (temporarily) disabling any firewalls, and security in the router settings. If you are then able to connect, re-enable those one by one until you find the setting that is causing the issue.
If all else fails press and hold the red reset button (On bottom of XR unit, on rear of others) for a full minute while powered. Disregard any rebooting just hold that button for a full minute.
