Thanks @Matwood26 this helped. Everyday at 4:30am all of my wifi compatible devices lose connection from Xfinity. This has gone on for 2 weeks. Xfinity says their system updates all modems then. And it shouldn't affect service. But it does everyday and this is annoying to keep rebooting this modem daily.
Download the Xfi app from your app store. Once installed, login to app, and follow these instructions:
Go to the Connect tab. Select See Network. Select Advanced Settings. Select 2.4 and 5 GHz WiFi.
Select edit next to the 2.4 GHz option. Once that opens you will see a drop down on the top under wifi mode...this is where you will see the option to change it.
So I came across the same issue I’ve had my Roku hooked up to our personal WiFi for a year+. This morning it stop working. I can hook up to my guest WiFi settings but not my personal?
OMG!!!! You are a genius and my absolute HERO!! I’ve been tearing my hair out for days resetting, rebooting, unplugging and troubleshooting this with ZERO luck until I saw this! Y’all definitely do this! as soon as I changed my wireless to the b/g/n reset/rebooted the roku AND the router one more time BAM connection was restored! Thank you so much!!!
Are you getting error 14.30?
Go into your modem/router/gateway configuration pages and make sure 2.4 is enabled and set for channels 1, 6, or 11 with a 20Mhz width (and set for B/G/N mode if similar to this XFinity issue).
Also make sure 5Ghz is set to channels 36-48 or 149-165 (36, 149 preferred) and NOT using DFS channels between 52-140 (Rokus dont support DFS).
If need be contact Cox CS and they can help you with it.
My new router (WIFI 6) did not initially work (error code 14:30 and all that jazz). My solution was defualt settings BUT make sure the Wifi 5Ghz channel is set to 44 or less... I read somewhere that Roku didn't work on channels 48 and above...
Hope this fixes it for you.
this thread has actually been more helpful than the 10 others I read
I will try the changes in the morning as I work evenings and have to head out today.
But thanks again, it sounds like you all are onto something
Thank you so very much! This worked for me as well! Roku customer service chat was not exactly helpful and even left the chat after I told them everything else in the house was working fine. So glad I looked here!
