Need to check the compatibility and what settings of the Netgear router may not be supported bu your Roku devices.
Post a list of your Roku device and RokuTV model numbers (from Settings/System/About).
Post the model numbers of the Westell and Netgear routers. The old Westall routers really were pretty good. Simple, cheap, and just worked; not many settings to get in the way.
What ISP (internet service provider are you using these routers with)?
Are you using a modem in addition to the router, or is your router the only equipment in place on your network?
------
Provide some details as to exactly what you are seeing and if you are getting any errors on screen (error numbers).
