By default, MacBook / Mac it automatically connects to the wireless networks for which we have saved passwords and to which we have connected in the past. These are saved in the account iCloud, so that if we connected in the past with iPhone to a Wi-Fi network, and Mac it will automatically connect to this network without the need to enter the password. In the worst case we will be asked to give share your wireless password from the other device already connected.
In the situation where we are in the coverage area of several Wi-Fi networks for which we have saved passwords or we have a router with 2.1 Ghz and 5 GHz, the MacBook will not connect to the network with the strongest signal and the best quality of internet but at the first network list of available connections. If we want to change the network to which the MacBook connects automatically, we will have to go to this list and change the order in the list of saved Wi-Fi networks.
How to change the order of automatic connection of Wi-Fi networks saved on macOS
1. Go to “System Preferences”→“Network"
2. In "Network"Select"Wi-Fi"From the list on the left, then click on the button"Advanced”From the bottom.
In the right to "Network Name ”appears the name of the wireless network to which we are already connected. In our case: UPC-CNT 5GHz.
3. In "Advanced" we have saved wireless network list that Mac connected over time. If we are in the coverage area of several Wi-Fi networks, the device will connect to the first one in this list. In our case, we are in the country of network coverage: UPC-CNT 5GHz, Apple Network 5GHz, Apple Network and UPC-CNT.
If we want the MacBook not to automatically connect to UPC-CNT 5GHz but to Apple Network % GHz, all we have to do is to select the network that we want to automatically connect to and bring it to the top of the list. Drag it with the mouse / cursor.
When the MacBook operating system restarts, it will connect to the first Wi-Fi network in this list.
Here again we can delete or add new wireless networks.
