Problems connecting with my Roku 3

After a software update at the end of June, my Roku 3 will not connect to the internet. It connects to Wifi, and we get a check mark on connection status, but it will not connect to the internet (red x there). I've tried all the usual fixes - unpugging and resetting the roku unit, doing the same for my wireless modem/router. I've contacted Xfinity and they have checked my system remotely and say they can't find anything wrong. I lowered my firewall settings on the router to minimum and still no change. Both of my smart TV's have been able to connect to the internet so the problem seems to be pointing to my Roku device. Could there have been something in that last software update that messed up my Roku 3's ability to connect to the internet? How would I know if my ROKU 3 is failing? It seems to boot up normally just as it always has - it just can't establish a connection to the internet. It literally worked on June 29th and has not since then. Would appreciate all of your help.

Re: Problems connecting with my Roku 3

@makaosant-

I suspect this is your problem:

Are you connecting to the 2.4 GHz wifi band or the 5 GHz wifi band?

Your problem may have been caused by an update to your router which affects some Roku models. If you receive this update it changes the router's wifi connection parameters for the 2.4 GHz wifi band from b/g/n to g/n. This has been reported for routers supplied by Comcast/xFinity, Cox, and AT&T, but there may be others.

Affected users report the Roku identifies the local network as available and rates the connection quality, but will not then connect. The fix is to switch the router configuration protocols from the g/n wifi set by the update back to b/g/n. If you don't have access to your router's configuration controls you may have to have your internet provider do it for you.

Thanks to forum user @AvsGunnar for providing the links below to instructions for reconfiguring router settings for the listed internet suppliers. If you can't do this yourself, you may need to contact your internet provider to make these changes for you:
