6. Limit devices

This solution is to limit devices on your network. If too many devices are connected, disconnect some. This can help reduce network congestion. As a result, it might solve your connection issue.

• Firstly, you need to access your router’s admin page. This usually involves entering an IP address into your web browser. Common addresses include 192.168.0.1, 192.168.1.1, or 10.0.0.1. Check your router’s manual or the label on the router itself for the correct address.
• Secondly, you’ll be asked for a username and password. If you haven’t changed these, they will be the default ones provided by your router’s manufacturer. Check your router’s documentation if you’re unsure.
• Next, look for a section called “Attached Devices”, “Device List”, “Connected Devices”, or something similar. This will be different depending on the router’s brand and model. Here you can see a list of all the devices currently connected to your network.
• Lastly, if you notice too many devices are connected, you can start disconnecting the ones not in use. Some routers may allow you to disconnect devices directly from the admin interface. For others, you may need to turn off Wi-Fi on the device itself.

Please be aware that these steps can vary a lot based on the specific brand and model of your router. Always refer to your router’s manual or support website for the most accurate information.

7. Check router

Next, check your Wi-Fi router. Is it working correctly? If not, it might be time for a replacement. Also, make sure it’s broadcasting the Wi-Fi signal properly.

• Firstly, look at the status lights on your router. Each router has different lights to indicate its status. Generally, there should be steady or blinking lights to show that it’s powered on and connected to the internet. If any lights are off or flashing in an unusual pattern, it might indicate a problem.
• Secondly, if possible, test the internet connection with a wired Ethernet connection. If the wired connection works but the Wi-Fi doesn’t, it’s a clear sign there’s a problem with the router’s Wi-Fi signal.
• Next, check if the Wi-Fi network is visible on other devices. If other devices can’t see or connect to the network, it might suggest that the router isn’t broadcasting the Wi-Fi signal properly.
• Furthermore, a simple restart often fixes minor issues. To do this, unplug the router from the power outlet. Wait for about a minute and then plug it back in. Wait for the router to fully restart and check if the Wi-Fi signal is back to normal.

Moreover, outdated router firmware can cause connection issues. 

• Check the manufacturer’s website for firmware updates. Follow their instructions to update your router if needed.
• If the problem persists, you might need to perform a factory reset. This will erase all settings on the router and restore it to its original state. You’ll need to reconfigure your network settings afterwards, so only do this as a last resort.
• Finally, if none of the above steps work, it might be time to consider a replacement. Older routers, in particular, can struggle to maintain a reliable Wi-Fi connection. If your router is several years old, upgrading to a new one could resolve your “Macbook Connection Failed Wifi” issue and provide a more stable and faster internet connection.

As always, if you’re not comfortable performing these steps yourself, consider seeking professional help. A professional can diagnose and fix router issues with minimal disruption to your network.

8. Inspect hardware

Inspecting your MacBook’s hardware, especially its Wi-Fi card, is a bit more technical than the previous steps. The Wi-Fi card is a piece of hardware inside your MacBook that handles wireless internet connections. If your Wi-Fi card or antenna is damaged, it needs repair or replacement. In that case, seek professional help.

The Wi-Fi card in a MacBook is typically located inside the main body of the laptop. The exact location can vary depending on the model of your MacBook. In some models, it’s located near the hinge of the laptop, in the upper case assembly. In others, it might be closer to the side.

However, it’s important to note that accessing the Wi-Fi card in a MacBook is not a straightforward process. It involves opening the laptop’s case, which can void your warranty if it’s still in effect. Therefore, it’s highly recommended to seek professional help if you suspect that your Wi-Fi card or antenna is damaged.

Apple provides support for their products, and you can bring your MacBook to an Apple Store or independent computer repair shops, such as VOLTA PC Upgrade & Repair, for inspection and repair.
