I have COX internet and this has happened to me the last few days (Very Frustrating) I couldn't find codes you spoke of at first, but rebooting my wifi from Cox seemed to work yesterday.
It happened again this morning and I was able to find the settting you posted via COX online portal and low and behold, just as yours? Mine was to g/n not b/g/n.
I changed it to b/g/n and it works great!
Hope that helps all!
I cannot thank you enough kind sir or ma'am. I was on the verge of dropping my two Rokus in the dumpster after dealing with this issue on and off for a month.
Just followed these directions in the Xfinity app. Once I switched the 2.4GHz to b/c/n, my Express immediately connected to the internet.
(I have an Express+ model 3910RW.)
Keep forgetting to post. I called Xfinity the other night and after a bunch of rebooting and being put on hold, the rep was able to reset my 2.4 gHz and the Roku connected. Then it disconnected 30 minutes later. She had emailed me the link to update my router so I was able to switch to the b/g/n and it’s worked ever since. Tho everything has been running a little slower.
Thanks for this tip!!
@Skinny68 It took a while for me to access the xfinity router settings online, but once I did, I was able to change the channel to b/g/n (or whatever the letters are that the poster said to do) and it’s been working so far!!
This option is not working even, I followed the steps but the problem is the same the intensity is very low and I used two Routers and a different red connection
Thank you so much for your posts. I am 72 and your info was easy enough for even me to follow! Many, many kudos to you!!!
