TCL Roku TV loses wifi connection and then can't find any wifi networks

Mon Dec 31, 2018 12:45 am

Hello everyone,,
The happens at least once a day (or more). Watching Netflix (and other channels), then get a network connection error and prompts me to set up new connection. I go to the network setup and scan for wifi networks and none can be found. My laptop in the same room is connected to same wifi with no issues.
I have then go to Settings -> System -> Advanced system settings -> Network connection reset -> Reset Connection.
This will reboot the roku TV and once it comes back up I am able to setup the wifi connection   like normal and everything works until this same cycle happens after a few hours of  using it.
My roku is updated to the latest software.

There's a known bug with some of the newer software.. happens to me. They're supposedly working on a fix, but it's been happening to me for over a month.
Yeah, I got some Rokus.

According to this article you should be able to do a factory reset to get the up to date firmware.

Not sure if it will help or not though.  Might be waiting on other updates.

Hi,
A year ago when I received my 2016-vintage Roku Ultra, I set it up in my home theater room, well off to the side of all the other equipment. I connected it to my WiFi router on 5gHz. The Roku and router are about 10 feet apart with one otherwise empty wood-stud-and-drywall wall between them. The Roku said the signal strength was "excellent". I checked the signal at the Roku with the WiFi analyzer app on my phone, and it concurred: very strong, clean signal. Be that as it may, the Roku would simply drop the connection from time to time...and far more often than was reasonable. I had updated the Roku's firmware when I first turned it on, yet, even after I reconnected it to my 2.4gHz WiFi, it would not maintain a reliable connection. My cable provider technician was visiting for another, unrelated, issue so I brought up the Roku's problem. He went out to his truck and came back w[color=#1c1c1c][font=Noto Sans, Helvetica Neue, Segoe UI, Helvetica, Verdana, Arial, sans-serif]ith a small cardboard box, which he handed to me while saying "try these". Inside the box were two white-wall-cube-type thingies. They each had some L.E.D.s and an Ethernet jack on them.
You plug one into a 120V outlet near your router, and then connect the cube and the router with an Ethernet cable. Then you do the same with the other cube near your Roku, connecting the Roku the same way. This gives you a reliable Ethernet connection between your Roku and your router. I checked the connection strength between the two cubes using an app provided by their manufacturer, They're good for between 600 and 850 mps in my location, which is WAY more than I need. That was the end of my connection problems with my Roku Ultra.

It has been perfect for over a year now, which is why I purchased another pair of the "cubes" (they are sold in pairs) when we bought our new TCL TV this Christmas. Before I ever turned on the TV, I connected it to an Ethernet "cube" (apparently, once your router is connected to your house's wiring with a cube, you can have a total of 16 cubes connected on your "home network"). When I then turned on the TCL for the first time, the internet connection was already "hot" and I proceeded to update the firmware in both the TV and the built-in Roku. This connection is on another floor in our house, so I again checked the connection speed, which was around 350 mps...still a good 20 times what I would need to stream 4k.

I know you don't want to hear that your Roku TV has an unreliable WiFi system, and maybe it actually doesn't...maybe there is some other extenuating problem, unrelated to your TV's Roku/WiFi, that's causing your connection problem. Heck, I still don't know what the problem was with my own Roku Ultra, but whatever it was, it was rendered moot when I bypassed the whole RF connection issue with these Ethernet wall cubes. So, if you can't solve your connection problem, I just wanted you to be aware that there is another, iron-clad, solution that's available to you...[/font][/color]

Sorry about the weird character string in the first paragraph...I don't know what happened, but it's my first post here.

It's a known bug with the wifi disabling on the TCL (and maybe other brands) Roku TV's, brought on by a software update sometime between October and December..

As I said, Roku is aware of the problem, and they are working on a fix.

My Roku Express 3900X suddenly lost wifi signal today. I did all the reset procedures, but there were no wireless networks in range.
I confirmed full signal with my laptop, as well as 6 other wireless networks in range.
I was only able to connect to my wireless network if I set up the Roku in the same room as the main wireless router.
The issue appears to be a sudden loss in wireless reception with the Roku.
I am not sure if this is an internal issue, or if it is a bug with the version 9.0.0 build 4083-51 ?
-the signal should have been 100%, but the Roku is indicating weak signal.
Note that I have been using the Roku without any signal issues at all , before today.
Do I try to take the Roku in as it is still under warranty?
Do I wait to see to see if it is a bug?
Bob

Yes, this has been happening to us for about 3 or 4 months. I’m ready to get a new tv if they don’t resolve it soon! The fix is to unplug the unit and then it can reconnect to a WiFi network.

Same issue here. Sometimes it's good for days but then I have to check connection to re-connect. I have excellent wi-fi so that's not the problem. Anybody out there know of a permanent solution? Appreciated.

My ROKU TV has been working fine for a little over a month and today it's gone crazy. It refuses to log in to the one network that it's been logged into but I can get it to log into another one, albeit poorly. It's literally sitting beside the router, but it keeps saying the internet connection is bad so I can barely stream. I tested my speed and it's beautiful, all other devices are connecting and running with ease. I see this is a known issue, but that doesn't much help me out now. What are my options for fixing this or an I best to just return it at this point? I've noticed this has been an issue on the boards from years past as well which doesn't make me feel very positive.

Sorry to hear about the issue you're experiencing. 

As I mentioned above, please feel free to PM me with your Roku account email address and the TV's serial number from Settings>System>About, and I'll help take a closer look to see if there is anything else we can recommend to help. You can take a look here to see some tips for improving the wireless connection to a Roku device: 
https://support.roku.com/article/213122277-tips-for-improving-the-wireless-connection-to-your-roku-streaming-device

In general, you'll want to start by contacting your TV's manufacturer directly to report the issue you're running into and request help. Each Roku TV manufacturer provides primary support for their devices, and can best assist with additional troubleshooting and any other warranty related options. 

Thanks,

I am also getting this on (2) TCL Roku TVs: a 49S305 and a 43S305.  We have a third Roku device, an Ultra, connected to a Panasonic TV and it has not exhibited this behavior (but we don't use it nearly as much as the other two TVs, not sure if that's something to consider).  It's been happening for a few months now, usually at least once per night recently.  My wireless is working perfectly but these TVs seem to just lose their wireless connection at random.

And when I say "lose", I don't mean they simply drop the connection.  I mean they act as if they have no wireless capability and cannot find any wireless networks.  I mostly use the Roku app on my phone to control the TVs since my young kids like to run off with the Roku remotes, so when this happens I have to either totally pull the power plug or dig up the real remote and turn the TV off and back on again before it reconnects to the wireless.

I grabbed a photo you can see here.  Ironically this photo was taken the only time it ever re-connected (after about 20-30 seconds) when this has happened.  All other times, even if we leave it sitting for a few minutes, have required a full reboot.

As best I can tell all our systems are running the most recent version, or at least a very recent version.  I've upgraded to the latest sequential software version a few times in a row over the past several months and it hasn't helped.

I have been experiencing the same Wifi disconnection issues for several months on my TCL 43S405. I am on software version 8.2.0 build 4170-30. A TCL support representative says the latest build I should be on is build 4174. Manually checking for software updates results in an all-software-up-to-date message without updating t 4174. Is anyone else able to update to 4174 or still experiencing issues *after* updating to 4174?

Loses the wireless connection every day.

TCL 32S327 32-Inch 1080p Roku Smart LED TV (2018 Model)
Purchased March 18th, on Amazon. 
I have the latest version (9.0.0, build 4151)  
I have no other devices on my network that lose their connection. 
Resetting the TV on its own does not re-acquire connection
Resetting the TV AND the router will allow for re-connection, however this only lasts a few hours. once TV is turned off, and back on, connection is lost
HARD reset of TV did not resolve either. 

Any thoughts, before I call technical support / return the tv ?

It’s as though there is heavy traffic or interference on that WiFi channel. That may or may not be on your network itself, but on the channel your network is using.

Try a different WiFi channel.
