So, you need to download the latest firmware from the Linksys website. However, you can also download the firmware by logging into the router and downloading the firmware from the administration tab.
In addition to updating the firmware, if you have recently downloaded the firmware, it might be causing the issues. If that’s the case, it’s suggested that you reflash the firmware and is likely to fix the error. As for the Linksys WRT1900AC Wi-Fi router, it is advised to opt for the 18.06.4 or 19.07.0 version because both of them are compatible.

In addition, you need to change the 2.4GHz radio mode from the mixed-mode to the B/G/N-only mode. When you change the modes, it’s better to restart the router, and it will help fix the 5GHz internet issues.
4. DFS Channel
In addition to changing the mixed mode, you need to be vigilant about the DFS channel settings to ensure the 5GHz Wi-Fi channel is working properly. Generally, people use the non-DFS channels, commonly channel 48 and channel 36. However, the non-DFS channels are suitable if there are multiple connected devices.

For the Linksys routers, you can opt for CAT5, CAT6, or CAT5E cables because they are suitable for directing and broadcasting the wireless signals, be it 2.4GHz and 5GHz.

So, it’s best that you call the internet service provider and have them share information about the network connection.
