When you try to connect through modem or router to the internet, the ISP (the internet service provider) assigns the IP address to your account.

The address is selected from several addresses that the ISP owns, where you can change the account depending on the kind of account signed up for.

Those having a static account will have the same IP address and the networks with a dynamic account have changeable IP addresses. The router routes the device connected to it and then it allows access to the internet connection.

The router creates several internal IP addresses which are the private addresses that are used only within the local network. 

As you log on to a certain network with Mac or an iOS device, you get one of the addresses. The address is like the name of the device on the network represented in the form of two or three-digit numbers separated by a period. 

One can configure the network preference by choosing the System preference from the menu and then selecting the Network preference. 

The options are dependent on the type of Mac used. A Mac with Ethernet port and the one that carries the Wi-Fi circuitry will display Ethernet and Wi-Fi entries. 

A green dot next to it shows active connections, that are not configured and a red dot shows inactive (or no connections). 

It also shows red when you have turned off wi – fi. 

There can be listings for Thunderbolt Ethernet, FireWire, USB Ethernet and Bluetooth.

In case you are using a supervised device, the option to forget the network may not be available.

If you use the alternative to forgetting a network, you can turn off the auto-join option and the device remembers the passwords and other details, but it may not connect automatically.

Sometimes, the network connection faces problem due to bad weather or other faults in cables or connection. To establish the problem, reboot the router. Turn the router off and then switch it on.

  • Disconnect the router from power for about 30 seconds and then plug it in to turn on. Reboot the Mac. Turn the device off and then after a few seconds turn it on and scan for available networks.

  • There are other tips like add passwords to networks to avoid automatic connection. 

  • Keep the router cool to avoid connectivity problems caused by overheating. 

  • The router should not be covered or kept hidden in places with low ventilation. The router should not be placed close to metal surfaces.

  • Sometimes the problem of connectivity is caused when the router is kept in a place like a metal cabinet. The router should not be kept next to a radiator. 

  • Place the laptop close to the router to get a clear signal and in conditions when the signals are proper when the laptop is kept close to router indicate something in the place (office or house) is interfering with the signals. 

To resolve the problem of weak signals, check the location of the router. If the house or the office has thick walls and the router is kept in an enclosed location, the problem can be caused by electrical devices like a microwave, wireless phone, motors and fans.

If the wireless signal strength drops at the same time as you run the microwave, then it can be interpreted that the interference of the waves is causing the problem. Try to position the device away from the microwave. 

How to resolve the network problems?

Use a wireless diagnostic utility

Mac OS built-in wireless diagnostic utility can help in such situations. If you click the report and check the performance, the graphs can show the transmission rate, the quality of the signal and the noise levels. If you monitor such details carefully, you will be able to identify the problem. You can see the condition when the level of noise increases if it coincides with the use of a certain electronic device. 

WiFi Explorer

Sharing and presence of networks nearby can also interfere with its function. Use the WiFi Explorer to find out what are the other networks in your work area to diagnose the problem. 

There are other ways you can find a solution to the problem of congestion on the device. Choose a unique name for your connection and you can opt for ways to change the channel of Wi-Fii to reduce issues caused by neighbouring connections.

Disconnect all the devices from the Wi-Fi and shut the Mac down and enter the Apple diagnostic mode to resolve the problem.

Changing the DNS setting and deleting the Wi-Fii preference files are recommended in certain conditions.

  • In conditions when things go wrong, the Wi-Fi broadband connection can lead to delays in getting emails and missing messages.

  • So if the Mac is facing the problem of slow connection, you need to find out the reasons and there can be three conditions that can lead Wi-Fi to stop working.

  • First is the problem with the router. The broadband provider can be down or there can be issues with the Wi-Fi network. 

  • In the past, many Mac users have faced the problems were following an update, led to the problem of poor wireless connectivity. 

Apple issued an update for the software but the users had the same problem and many were not able to connect to the web through Wi-Fi. Users had to use a new version of macOS to access the connection.

Users should be careful if they are sharing networks to see they are not giving their data to shared connections. For the problems related to the provider, you may not be able to find a solution immediately but for software related issues, run the ping test and check the diagnostics to find quick solutions.
