Roku will not connect to wifi anymore.

My roku stopped working this morning. It was working perfectly fine last night and then this morning it said it wasn't connected to wifi so I tried to set it up and it isn't finding any networks to connect to. We have had it for at least 2 years with no issues until now. There are 3 other Rokus in the house that are working perfectly fine and ours isn't even the oldest model of the four. I know it isn't a wifi issue as every other device connects just fine. We have tried everything. We've tried restarting the wifi router, restarting the roku, entering the wifi information manually, resetting the network settings, unplugging the roku, I even factory reset the roku which made the problem worse because it still can't find a network so now I can't even set the roku back up. Is it a lost cause or what can I do to fix it? I'm not exactly sure on which model it is but I believe it is the roku premiere+. I do have the model number.

@Shylah 

Always include the model number. Some Premiere+ models support both 2.4 GHz and 5 GHz bands, and some are 2.4 GHz only. The model number is always useful to provide with any issue; likewise, the Roku software version. Settings > System > About

Who is your ISP? Do they control your wireless router? Or do you have your own?

Some ISPs who manage their wireless routers have changed to 5 GHz only. Some ISPs, particularly Comcast, have changed the 2.4 GHz settings to g/n from b/g/n, which can make a difference.

Re: Roku will not connect to wifi anymore.

I just starting having the same wifi connection issues that you described Shylah, and performed the same troubleshooting efforts as you, with the same negative outcome on my Roku Premiere device (Model 3920X). Even did the factory reset in frustration like you did, making the situation worse, because I can't even verify that my icon history is still in place. I would add that in my case, I started noticing slow, halting performance a couple of days before full wifi disconnection occurred before the inability to reconnect started. Bought my unit in November, 2020, so it's less than a year old.

You haven't indicated if you looked into the WiFi settings of your router, if your ISP provides it. Your device is 2.4 GHz only, so what I wrote would apply to your situation.

You did provide the model number, which tells us your device is 2.4 GHz only, b/g/n. But the rest of my suggestions to @Shylah aren't addressed by you. That should be checked.

If you do decide to go with a warranty replacement (https://support.roku.com/article/208757058), unless Roku upgrades your device, your replacement will be another 2.4 GHz device. If the issue is the stuff I suggested you check, that will still exist.

Re: Roku will not connect to wifi anymore.

Thanks for your input DBDukes, but I'm not having a compatibility problem. I checked with my ISP (Comcast/Xfinity) and my WiFi modem covers both 2.4 GHz and 5 GHz. That hasn't changed since I purchased my Roku Premiere device last November.

Fortunately, I am able to make a warranty claim, since it's been less than 1 year since my purchase. I've already arranged for the return and plan to ship it back to them today.

Re: Roku will not connect to wifi anymore.

I just had this problem with 3910X. After a million different tries. I found that you have to go into your router and switch from auto to a specific broadcast channel. I did channel 6. I'm not able to accurately tell you, but it worked for me. Go to a computer type cmd then config. It's better you look it up. Good luck

Double check the details of the 2.4 GHz settings. Comcast changed some of their wireless devices from b/g/n to g/n. That will stop your Roku from connecting.

If your Comcast wireless router is set to b/g/n, this isn't it. If it's g/n, change it and see if that fixes it.
