Roku Express not detecting wifi

I have restarted both the Roku device and the router. Still no detection of wifi. Wifi is working because computer and phone do not have any issues connecting.

I have the same issue and kind of figured out that changing 2.4 wifi's channel makes Roku detect it again. My question is - this seems like a bug and should be fixed. Is there anyone on this forum who knows if Roku is planning to fix this? It is very irritating.

I have done this all will find my phone hotspot but not other hotspot. 

I am with you. I also did all the stuff that you mentioned. I believe this issue is hardware related. In my case, when I used the phone´s wifi I needed to put the phone a few inches from the device, yet it sees the hotspot with a very low intensity.

I read somewhere that these units run so hot that the internal wifi chip could be damaged in the long term. Mine runs between 158F to 185F (info from hidden menu) and it was always plugged into the outled since I bought it (3 years ago). But the strange thing is that it was working fine before the firmware update. Could be a coincidence. For the record, mine is a Roku Express+, the one that has rca A/V plugs

For Me this is now fixed.  After everything I did, including doing some trash talking about Roku I looked at my routers firmware.  It was almost 3 years old, from Dec of 2017, DD-WRT v3.0-r34311.  I looked up the latest version, on https://forum.dd-wrt.com/phpBB2.  For my Linksys WRT1900AC v2, it is v3.0-r40559.  I downloaded & graded my WRT1900AC.   It restarted to the upgraded FW, no runs, no drips & no errors.

I turned on the Roku, it booted and there was my WLAN.  Moral of the story, for me, anyways ...  Do your homework and cover all the options, including the ones where it your own fault too.  I did not check to see which previous versions of DD-WRT worked, the latest does and I'm happy.  Had I kept my router updated more, would this still have happened?  IDK, but it you have any open source router I'd suggest upgrading to the latest stable version.

Have a Great Thanksgiving everyone!!

You can't change the WiFi frequency band. The Express only works in the 2.4 GHz band. What you can change is the channel, which makes a minor frequency change within the 2.4 GHz band. 

In this day and age, you should see numerous neighboring WiFi access points. If your Roku is showing absolutely none, there's likely a hardware or software issue with the Roku. Can you try using a hotspot on a phone and see if that can be seen?

Thanks for the posts.

I would recommend checking out our Support page for troubleshooting issues here: What should I do if I cannot connect to my home network or the internet?

Please answer the following questions so we can get a better understanding of what you are seeing:

- Have you ensured your router is broadcasting a 2.4GHz Wi-Fi network for the device to connect to? The Roku Express is only compatible with wireless b/g/n networks on the 2.4 GHz spectrum. 
- Have you tried changing the wireless broadcast channel on the router to see if this will allow your device to connect? 
- Have you tried moving the device closer to your router to see if you can get connected? 
- How long have you been experiencing this problem?

If those things still aren't helping, feel free to send me a PM with your Roku account email address and the serial number of your Roku from Settings>System>About along with the answers to the above questions and I'll be able to assist you further from there.

Thanks,
Danny

My Roku Express + that I've had for a year has suddenly started disconnecting from Wifi every single morning.  It does not reconnect unless I do a reset or unplug the unit from the power cord for a minute.  After a reset, it connects and I can proceed on with my day with no issues until the next morning when I have to unplug it for a minute again.  My Roku Streaming stick does not have the issue, and none of the other items in my home have wifi connection issues (Nintendo Switch, iPad, work laptop, home laptop, iPhone).  The Express+ unit has been in the same spot for over a year and is actually about 12 feet from my router.  Because this is a new issue, it seems that there must have been an update or something that makes this one device not connect to wifi unless it's reset.  Oh, and I've checked for software updates too.

I feel for the other people experiencing this.  Trust me, I understand! 

Mtk7782 While you haven't changed anything, your wireless might have made changes you are not aware of. If your ISP controls your router, they might have disabled 2.4 GHz. For some strange reason some ISPs have been doing that without notifying the users, or hiding it within some sort of marketing mailing or email. By default most routers are also set to auto-select the channel they use for WiFi. On the 2.4 GHz band, the available channels are 1-14. However, Roku devices will only work on channels 1-11, so if your router changed itself to 12, 13 or 14, your Roku will not be able to see or connect to it. 

So, check your router and see if a) 2.4 GHz is enabled and b) change the channel from Auto to channel 1, 6 or 11 (those are the three best channels to use on 2.4 GHz).

Your other two Roku devices might support 5 GHz, so if your ISP turned 2.4 GHz off they would still see and connect to the 5 GHz radio. That would explain why they still work.

What is your Roku model number (Settings/System/About), your router model number, and ISP (internet service provider).  Also indicate if you are you seeing any error messages on your TV screen.  Need a few more details to troubleshoot.

Thanks for the post.

Can you please specify the issue you are experiencing? What Roku model are you using? Is your Roku device already setup and activated? Was the device working before?

With more detailed information, we will be able to assist you further.
