Wi-Fi & connectivity

[usergarg]

Hi

I recently started using Three network home broadband which is using 5g network and my Roku express is not connecting to internet any more. I have tried:

Restarting Roku 

Resetting  Roku

Restarting Modem

Trying connecting Roku with 2.4GHZ but it won't connect.

When I connect it using my mobile network or any other fiber network it connects easily.

Please help on how to connect Roku with Three UK home broadband Modem.

Thanks.

There are some router setting issues that can prevent establishing Roku WiFi connections. And to make matters worse, some of them can be set by recently-reported router updates. These have primarily been reported with routers supplied by internet providers (in the US, Comcast/Xfinity, Cox, and AT&T so far), but it's possible they could also occur with other internet providers or user-owned routers that have received similar updates.

• ROKU LOCATES NETWORK AND REPORTS NETWORK QUALITY BUT CANNOT CONNECT
  Some router updates have changed the router's connection settings on the 2.4 GHz WiFi band from b/g/n to just g/n, causing Rokus connecting to the 2.4 GHz wifi band to lose their ability to connect to the network.
  
  Note that, of recent Roku models, non-4K Roku Express/Express+ (model numbers below 3940) and Premiere/Premiere+ (model numbers below 4620) can ONLY receive the 2.4 GHz band and are therefore affected by this.
  
  The solution is to set the router's configuration back to using b/g/n.
   
• ROKU CANNOT FIND LOCAL WIFI NETWORK AT ALL
  There are several possible causes.
   
  A) 2.4 GHZ WIFI BAND TURNED OFF
  Some recent router updates have turned off dual band routers' use of the 2.4 GHz band. Some Roku models, notably Roku Express/Express+ non-4K models (model numbers below 3940) and Premiere/Premiere+ (model numbers below 4620), are lower end units with single band WiFi radios that only support the 2.4 GHz band. They, and many other devices of all sorts that are 2.4 GHz only, can't even see the 5 GHz band, let alone connect to it. If you have a 2.4 GHz only Roku model and a dual band router with both 2.4 and 5 GHz bands, be sure the router's 2.4 GHz band is turned on.
   
  B) WIFI CHANNELS 12-4
  In the 2.4 GHz WiFi band, all Rokus support channels 1-11, as are used in North America. If your router supports 2.4 GHz channels 12-14 that are used in other regions make sure your router is set to use a channel in the 1-11 range and that you aren't using an auto setting that could select channels outside this range.
   
  C) DFS CHANNELS
  All Rokus that have dual-band WiFi radios can connect to the 5 GHz wifi band in two ranges of channel numbers, 36-48, and 149-165.
  
  Channels between these two ranges are reserved as Dynamic Frequency Selection (DFS) channels and are shared with other uses such as military, radar, and weather. Only some of the newest Rokus using the latest WiFi processors can receive these DFS channels.  (See https://support.roku.com/article/213122277 and scroll down to "Models that do not support DFS channels".)
  
  Many home use modems do not include the DFS channels but some do, so if yours is a dual-band Roku that cannot find your WiFi network, try setting your router to NOT use DFS channels. If your router supports DFS channels and you can't turn them off, make sure you aren't using an auto setting that could select DFS channels.

If your problem was not caused by any of the above, a restart of the router (even if other devices are still connecting) followed by a restart of the Roku may allow the connection to be reestablished. Depending on your Roku model you'll find the "System restart" option under either "Settings > System > Power" or if you have no "Power" option, under "Settings > System", or if more convenient you can just pull the Roku's power for a few seconds and let it restart.

I've just had this come up, I've just moved house and the same issue with the 3 three 5g router. I've done a bit of searching around and found someone online that posted the following and it's solved my problem, I've spent about two hours trying to sort it and then stumbled across this, which originally was meant to sort out someone accessing netflix, but it's now allowed my Roku to get an outside connection. Hope this helps someone in the future-

ORIGIONAL POST.

Since receiving my ZTE 5G router I have experienced many problems. The main issue being my Lounge TV wouldn’t run the Netflix app. I rang Three, then Netflix, and finally contacted Samsung, the TV is under warranty. None of the services could offer a resolution. I contacted an engineer who was unable to solve the issue. Following and during the process I searched the internet for possible causes. On finding a Forum post I discovered a possible solution.

In the router settings change the APN setting from 3internet to three.co.uk.

Netflix and all other services are now working!!! 

Now, my question is: have I weakened any security issues by changing the original 3internet setting? When I log in to the router admin via the IP address 192.168.0.1 my windows 11 Edge browser address bar displays NOT SECURE!

@BRNYS8558, many (most?) routers don't support https for their admin webpage (which you're getting when you connect to https://192.168.0.1).  It means that particular connection from your Windows computer to your router isn't using a secure connection; it doesn't mean that your entire network isn't secure.  Technically, anyone in your home connected to your network could capture the traffic from your computer to the router's admin page, but hopefully there's no one living in your home that you don't trust.  🙂  You can safely ignore that warning for that webpage.
