Wi-Fi & connectivity

[Ming_]

Is roku express+ the same as roku express 4k+? I need an Ethernet adapter & my model # (3931x) isn’t listed on the device compatibility chart. Also, will I have to have wires trailing all through my house to the router from my other tv’s that are in various rooms?

Why do you need Ethernet? The only Roku device with an Ethernet port is the Ultra. The Roku website allows you to compare each device side by side. It gives you a full description. Why don’t you want WiFi? There is no such thing as an Ethernet adapter for Roku

I have wifi. The roku stopped working on it. The cable guy came out & said that’s what I needed. Even before the roku stopped working, the wifi would constantly disconnect from the roku.

Then it seems you have an issue with your WiFi that needs to be addressed. Obviously the tech who came to your home doesn’t know a thing. If you a newer modem, a good clear signal and at least 25 Mbps there is no reason Roy need to use Ethernet. The Roku Express you are using only does 2.4GHz. You need to change your modem settings or else buy a dual band Roku.

They are not the same device.

Your device is 2.4 GHz b/g/n only. Many ISPs who supply the wireless router have been changing the 2.4 GHz settings to g/n, which will prevent Roku devices from connecting and working properly. If you are able to change the settings back to b/g/n, it is very possible things will start working again.

Alternately, you could get a newer Roku device that supports dual band (of the current ones, the Express is the only 2.4 GHz only device, so avoid it). Look for dual band listed as being supported. That's very likely the key to what's going on. That and your ISP screwing around with your settings.

The USB Ethernet adapters are only available for the newer dual-band devices like the Roku Express 4k/4k+ devices (models 3940/3941) and the Roku Streaming/Sound bars.  Also reportedly available for some Roku tvs, although not directly supported.

Since you have the Single-band 2.4ghz only Roku Express (model 3930), unfortunately, you cannot use an Ethernet adapter on that device.

As @DBDukes mentioned, it is most likely a setting on your 2.4ghz band in your router causing the issue.

If you post your router model and ISP, can most likely provide you with instructions to make some recommended changes.

Otherwise, have your cable guy verify your 2.4ghz in Enabled/on, you are using b/g/n mode protocol, and have him try different wireless channel settings to see if performance improves.

Not quite true.  Some Roku devices support a commodity USB to Ethernet dongle.  Specs and comparability elsewhere on thus website.  I have my streambar connected this way, works very well.

Also, 3rd party wired to wireless bridge units can help with some WiFi problems.  Some WiFi routers can be configured to "bridge" mode, connecting Ethernet cable to the Ethernet port marked "WAN".  Or as secondary router mode ("WAN" port again)

3rd party adapters. But nothing made by Roku
