Your Mac can connect to your home network in a variety of different ways. This can be over Wi-Fi or ethernet. If you have both connected you can choose which network method to pick. For example if you are in your home office on your laptop you can have both the Wi-Fi connected, or the ethernet connected. Having both connected means if you take your laptop for a walk you are still connected and keep the connection alive. The problem with this is that if you have the slower network connection first (usually Wi-Fi) it can slow you down. This tip is going to show you how to order your networks to pick the fastest.
Ordering Your Network Connections
Ethernet, cabled, networks are generally faster since they receive little interference. Therefore we want this to be a priority when you want network traffic to move. Since you Mac can only use one at a time (but it can be connected to more than one) you want the fastest one to be first.
To select the order open System Preferences and select the Network preference pane. In the left hand column select the little cog and select Set Service Order.
A small box will appear asking you to set the order. Ideally you want Ethernet to be first followed by Wi-Fi. These are usually order in terms of speed. However, you can set them how you like.
Press OK, and then press Apply from the main window. This change will take effect. Your Mac will now transfer data through the first selected option.
Ordering Wi-Fi Connections
If you have many available Wi-Fi connection points you can select the order in which you Mac connects to them. You may always want to connect to your office Wi-Fi point, before you connect the the neighbouring one.
To do this, within the Network pane again select the advance button while having the Wi-Fi option selected. Within the Wi-Fi tab, select the Wi-Fi names and order them by dragging and dropping the names into the order you want.
When you Mac sees the Wi-Fi connections it will connect to the first one in the list. If this is unavailable or times out, it will connect to the second one and so forth. This way you can order the networks you want.
