Network adapter - Code 45 Issue - RZ616 Wi-Fi 6E 160MHz

Hi William

Just to clarify, I did a system restore to 22/03/2025. The Code 45 issue began to occur on 14/03/2025. Therefore, I don't think the system restore gives us any information about whether it's a hardware or software issue. I only did the system reset so I could see RZ616 on my device manager after uninstalling it.

I've contacted MSI support. I will also contact MediaTek.

Thanks

Hi Phong

We've got your reply. So this error code persists even after a system reset. We have to say that you have indeed tried every solution we can think of, even some methods that have been reported to work for other users. Unfortunately, they still did not work in your case.

Have you tried contacting MediaTek or MSI support? This should be a hardware issue, since every method on the software side did not work. Let's see if these engineers have any useful suggestions.

Update on the 'Current Situation and New Problem'

I did a system restore to 22/03/2025, which was when I applied solution 2 (where I uninstalled RZ616 and drivers, and then reinstalled driver via the 'Network Controller'. On the restore (i.e. initial restart), RZ616 reappared and I got a "hardware settings have changed" notice - I note that I am still getting a Code 45 issue. Upon the second restart, I am still getting a Code 45 issue.

I also got a notice from an app called Malwarebytes (which I installed weeks ago), that I needed to install '.NET Desktop Runtimer' to run the Malwarebytes application. But I don't think this is relevant. 

Thanks

Hi William - thanks for responding.

I will try your solutions as set out below.

Solution 10: Turning Off Bluetooth (by Turning it Off in Bios) and Resetting

• Did it Work: No
• As above, I have noticed that by Bluetooth connection has been very choppy when I use my wireless headphones.

Solution 11: Disconnecting the Power Supply and Holding the Power Button for 20 Seconds (Similar to Solution 6)

• Did it Work: No
• Initial Turning On: No... But Did Say “Hardware Setting have Changed”
• Second Restart: No

In relation to the “Windows will say the drivers are updated (...)” and Compatible Drivers

• How many available drivers are there in the list?
  • From memory, when I click in the “compatible” drivers list, it simply shows the name of the network adapter “RZ616 (...)”, and then clicking on that option will give the “Windows has successfully updated your drivers”
• Can I Install a Different Version of Driver? Or Will the Eventually Installed Version Always be the Same?
  • The only one which Windows says it installs is the “compatible” one (i.e. I click on “RZ616 (...)”
  • If I try install the driver which I downloaded from the Microsoft catalogue or “automatically” search for compatible drivers, then it says I already have the best drivers

When I uninstalled RZ616 AND the driver software, I can see the network controller after restarting TWO times. I want to note that the network controller also has a Code 45 issue. When installing the drivers to the ‘Network Controller’:

• “Search automatically for driver”: Windows could not find drivers for your device
  • “Search for updated drivers on Windows Update”: Shows nothing and I have installed the latest windows updates
• “Browse for drivers on your computer”: I then chose drivers which I downloaded from AMD website and Microsoft Catalogue but neither worked
  • I then chose drivers which I downloaded from MSI website and Windows said it successfully updated my drivers. I cannot recall exactly what driver this is although the files inside say “WIFI_MT7902” / “WIFI_MT7922” /  “WIFI_MT7961” /    I do not believe this is the 3.4.0.1063 driver. However, when I restart and check the driver details of RZ616, it still says it is the 3.4.0.1063 driver.
    • Even after uninstalling, I have the same Code 45 issue.
    • Here are the details for the driver I downloaded from MSI:
• “Let me pick from a list of available drivers on my computer” (which shows both “compatible” and “all drivers in the same category as the device”): This shows far too many options, many of which are dated several years ago.
  • I scrolled down to Mediatek and these are the options:
    • 802.11.ac Wireless LAN Card Version 5.0.57.1 [18/05/2015]
    • 802.11.ac Wireless LAN Card Version 5.1.22.0 [21/04/2015]
    • 802.11.n USB Wireless LAN Card
    • 802.11.n Wireless LAN Card
    • Mediatek MT7630E 802.11bgn Wi-Fi Adapter
    • Mediatek MT7633E 802.11bgn Wi-Fi Adapter
• I tried uninstalling the RZ616 and driver software and, instead of updating the drivers from device manager, I tried to simply use the AMD Software Adrenalin installer to see if it would download the latest drivers. I restarted after using the AMD installer which prompted the “Hardware has changed” – I note that RZ616 was not in the device manager. After I restarted again, RZ616 was still missing and the Network Controller was still showing as a Code 45 with no drivers. Therefore, I resorted to using drivers I installed from MSI website (as above) which show the 3.4.0.1063 driver.

I wanted to note that, when I uninstalled RZ616 WITHOUT deleting the driver software and restarted my PC, my PC does not automatically reinstall the device: I cannot see RZ616 under Network Adapters and I cannot see any Network Controller. I was able to get it back by downloading the drivers from AMD website (AMD Software Adrenalin), and then restarting which gave a “hardware has changed” notice, and then restarted again. Despite this, the driver version of RZ616 will still be 3.4.0.1063 (29/06/2024).

Current Situation and New Problem

I uninstalled RZ616 again without deleting the driver software, but now neither RZ616 or the Network Controller is showing. I tried the same fix of using the AMD Software Adrenalin but this did not work this time. I’ve also tried uninstalling and reinstalling the latest Windows updates but this does not work.

Thanks

Hello Phong Ta

Thank you for raising questions in our community and sharing your attempts to solve the problem with us!

Based on your attempts, we understand that you have indeed tried almost every possible solution, but unfortunately the problem is still not solved perfectly. This does make your problem more difficult. We first noticed that your wireless network card model is RZ616. According to our experience and searching on the Internet, many users have reported that this product model has some hardware defects. It is a modification of another "notorious" wireless network card model. Some users reported that it conflicts with the Bluetooth module. The wireless network module will be unstable when Bluetooth is turned on.

Some users mentioned that removing static electricity from the motherboard can make this component work more stably. The steps are:

1. Disconnect the power supply: Before working on the motherboard, make sure the computer is completely powered off and unplug the power cord.
2. Press and hold the power button: After unplugging the power cord, press and hold the computer's power button for about 10-20 seconds. This can help discharge the residual charge in the motherboard capacitors.

In addition to the above hardware suggestions, we also pay attention to the ‘Windows will say the drivers are updated if I pick from a list of ‘compatible’ available drivers on my computer.’ part in Solution 3. Do you notice how many available drivers are there in the list? Try to uninstall RZ616 from Device Manager again, then check the compatible drivers when installing the drivers for the ‘Network Controller’ under ‘Other Devices’. Could you install a different version of driver? Or no matter which version you try to install, the eventually installed version is always the same?

These are our preliminary suggestions for your problem at present. We welcome you to give us more information so that we can try to solve this problem together.
