When you find that your Mac computer cannot connect to the wireless network, you can try to turn off and on the wireless function again. Click on the wireless icon on the screen and select the Turn off Wi-Fi option. After waiting for a while, click the wireless icon again, select the Turn on Wi-Fi option, and try to reconnect to the network. This simple step can sometimes resolve wireless network connection issues.

Delete wireless network cable configuration
Another situation is that you could successfully connect to a wireless network before, but suddenly one day you find that you cannot connect successfully. If this is the case, we have also tried the above method. We can also try to delete the wireless configuration file and then reconnect to the wireless. Or click on the wireless network icon, and then click on the bottom to open the network preference options, as shown in the picture

Finally, try turning off wireless network management and reconnecting to the wireless network to see if that solves the problem.
If you encounter broadband connection problems, you can first try to use the broadband network cable directly for testing. If the problem is indeed caused by the broadband itself, you can contact broadband customer service for resolution.
2) If it is a problem with the router, if it used to work, it cannot be used temporarily. My own practice is to cut off the power of the router, plug it in, and wait and see. If you have it, you can restore the factory settings and strictly follow the instructions to set it up again. If you don’t understand it, it is not recommended to set it up by yourself (this is under the premise that the physical connection is correct, sometimes it is caused by the router being slow or failing to find the IP address, and It’s not that the router is broken).
If you have been unable to solve the problem, I suggest you call the router’s customer service number. They provide online guidance over the phone. I've had problems myself that I couldn't solve, and the advice they gave me was very helpful. They will give you the right advice based on your setup or operation.
3) If you cannot connect to the wireless network, you can try the following methods: first check whether the wireless switch is turned off, and if it is turned off, turn it on. If you are connecting to the wireless network through software, but the software is not smooth or problems occur frequently, it is normal. The best solution is to use a router to connect to the network. In addition, there may be a lack of or inappropriate network card driver that prevents the connection, or there may be a problem with the network cable interface or the network cable itself. In this case, you need to check whether the network card driver is installed normally and ensure that the network cable interface and network cable are not damaged.
4) If it is caused by a system problem, it is recommended to restore the system or reinstall it.
Apple Computer Wireless Network Card Settings
First, we need to check the signal strength of the wireless network card of the Apple laptop. If you find that the signal is very weak, there may be a wireless network card hardware problem.
2. Please check your wireless network connection again and make sure there are no spelling errors in the Wi-Fi address, username and password you entered. This is a common mistake that can result in being unable to connect to a Wi-Fi network.
3. Check and clear the old Wi-Fi name in the preferred network of the wireless network card connected to Wi-Fi, and then reconnect to Wi-Fi to see if the connection can be normal.
Router Settings
1. Restart the router.
I have encountered the problem that Lenovo computers can connect to wireless wifi, but Apple laptops cannot connect. After restarting the router, the wireless WiFi of all computers needs to be reconnected. At this time, the Apple notebook can also connect normally. The problem lies in the code allocation of the router.
2. Wireless mode configuration
Many wireless routers now use BNG hybrid mode as the wireless mode, but some Apple computers do not support this mode. To solve this problem, you can change the wireless working mode to BG hybrid mode and restart the router. This problem is mainly caused by different wireless network card standards.
The first step is to restart the Mac wireless network card
To resolve wireless network connection issues, first click on the wireless network icon at the top of the desktop and select "Turn off Wi-Fi" in the drop-down menu. Next, click the wireless network icon again, select "Wi-Fi: On" and restart the wireless network card. This can often resolve some common wireless network connection issues. I hope the above methods will be helpful to everyone.
The second step, restart the router
Using the router for a long time may cause overheating problems. To resolve this issue, you can try turning off the router, letting it sit for a while, and then turning it back on. Doing this may solve the problem.
The third step, restart the system
If the problem still exists, you can try restarting the system to solve it, which usually has a certain effect.
Step 4: Delete useless wireless networks
In some cases, your Mac may not be able to connect to WiFi. One possible reason is that the wireless network signal is on the same frequency band. To solve this problem, we can try to delete some useless WiFi networks. Doing this can help your Mac reconnect to WiFi.
First, click on the wireless network icon at the top and select "Open Network Preferences" from the drop-down menu. This is the first step.
Step 2. In the network preferences, enter the "Advanced" option.
Step three is to select other useless WiFi names, and then click the "—" symbol to delete these useless networks.
