Roku has been a streaming giant for quite a while. It is not because of some special sauce; it’s just they keep the experience and UI simple. However, some say that technical errors are bound to happen. Roku Error Code 018 is one of those errors. This error pops up because of slow internet, which leads to loading screens not being able to open. In this article, we will try to resolve this issue with some of our tried and tested methods.
7 Methods to Fix the Roku Error Code 018
The following are the 7 methods you can use to fix the Roku Error Code 018.
Basic Troubleshooting Methods
With the basic troubleshooting methods listed below, you can easily troubleshoot the Roku Error Code 018.
We believe that before trying any major method, you can try power cycling. This is a simple yet very effective method that many Roku has vouched for. By doing this, you can simply delete any corrupted DNS files that might have been affecting the internet connectivity.
 You should first shut down your Roku device as well as your router. Once you have done this, unplug the power cord.
 Wait for your Roku device and router to completely shut down, and then wait for another 5-10 minutes.
 After you have waited, plug the power cord back in.
Now you can boot up your Roku device and your router to complete the power cycle.
Removing Any Electromagnetic Objects
When you get Roku Error Code 018, there might be a chance that the internet is slowing down. Now, this can sometimes happen because some electromagnetic devices, such as generators, Loudspeakers, etc., tend to absorb all signals.
The best way to solve this issue is to remove any electromagnetic devices like the ones mentioned above from the vicinity of the router, smart cast box, and smart TV.
By doing so, there is a chance the issue is resolved.
Troubleshooting Methods Related to the Internet to Fix Roku Error Code 018
With the methods below, you can easily fix the internet connectivity issue. Thereby fixing the Roku Error Code 018.
Check Internet Connection
Now to complete any internet troubleshooting method, you need to check whether the internet is working properly or not. Luckily instead of trying any third-party website, we can check it directly via Roku. You can check your connection in Roku fairly easily by a diagnostic test. To do that test, follow the steps mentioned below:
 Turn on your Roku device and press the Home button on your remote. On the home screen, select the Settings from the left pane.
 From the Settings, select the Network option.
 From the Network section, choose the Check connection option.
 Once you click on that, the system will start its diagnostic run, taking a few minutes to complete.
Once the system has completed the system diagnostic, it will show the results to you. As a result, you might get two types of results. One is you will be good or excellent, meaning it is working fine. But another is bad or poor; this will mean that the Roku device is not getting internet up to their standards. For the latter scenario, try some of the diagnostic methods we have suggested below.
Enabling the Disable Network Pings
We have chosen this method as the first one because only for this one method you will have to access the Roku Secret menu. This secret menu can be accessed by tapping on some buttons of the Roku remote in certain protocols. By enabling the DNP or Disabled Network Ping, it can stabilize the network as well as strengthen it. By doing so, you might be able to remove Roku Error Code 018.
 First, to access the secret menu, you have to press the Home button on Roku remote 5 times.
 After doing so, press the following button in proper sequence Fast Forward, Play, Rewind, Play, and Fast Forward. The system settings screen will appear on-screen.
 Open system operations on the list, and you will see an option.
 From the list of options, select Disable Network Pings and enable it.
Switching Network Security Protocol
In some network security, they use the AES method. Now, this is somehow conflicting with Roku. Because of this, Roku sometimes refuses to connect to the internet. For that scenario, we suggest you change the protocol on your Router. But this does come with an asterisk that is you are updating the security settings on your network, so you have to acknowledge the fact that you are doing it at your own risk.
 Check the panel or below the router to find the IP address. If not, check your manuals; it will look something like 192.168.8.1.
 By adding your username or admin and password, which will also be mentioned on the back panel or the manual, you can open the Router settings. In that, navigate to Wireless or security in settings and make sure the security mode is not set to AES in any way. Select the WPAK2-PSK as one option (TKIP).
 By doing so, you have changed your security mechanism. Now try connecting your Roku and see whether the error code 018 comes up or not.
