Roku premier won’t connect to wifi

I’ve had my roku premier for about two years I believe. It was fine until the last maybe 6-8 months? Nothing changed with my internet, router, etc. it just won’t connect now. It shows my wifi strength is strong. All of my other devices connect just fine. I’ve restarted it a million times, restarted my router, doesn’t fix anything. I did a factory reset, did nothing. It randomly decided to work again for a couple months, now it’s back to not working. Is it just trash at this point? Super frustrating.

Re: Roku premier won’t connect to wifi


I am assuming this is probably the 3920 Premiere (since you have only had it for a couple of years).  You can verify this under Settings/Systems/About.

This device can only connect to your 2.4ghz band so has to be enabled and configured correctly.  If you have a cable ISP (internet service provider) like Xfinity/Comcast, Cox, or AT&T, then there are known issues with some of their router firmware upgrades that are causing connection issues with 2.4ghz devices like the Roku Premiere.

If your situation is the above, then try changing the Wireless Mode in your router to b/g/n. (This setting will be located under the 2.4 ghz Wireless/wifi settings).


Instructions for Changing the Router/Gateway Settings….

AT&T → (https://www.att.com/support/article/u-verse-high-speed-internet/KM1046172). You can select your appropriate router from the drop down menu.
