If you’re using a public Wi-Fi connection, the service provider can use your MAC address to limit or track your usage. Internet cafes often use the MAC address to identify a particular device on their network. MAC addresses can also be used to assign static IP addresses and can be filtered further to limit the number of device connections in a network. However, if you know how to find the MAC address on your MacBook, you can use that to help identify your computer’s IP address.Īdditionally, internet service providers can use your MacBook’s MAC address to control your access. Your MacBook can also sometimes fail to display its IP address, leading to the said error. That’s because IP addresses can be hidden through VPNs (Virtual Private Networks). Sometimes, you might encounter a “No Valid IP Address” error. Why Would You Need to Find the MAC Address on MacBook The MAC address is often found on a device’s network interface card (NIC) and is required when locating a device or when doing diagnostics on a network device. The last six digits, on the other hand, represent the Network Interface Controller assigned by the manufacturer to the device. The first six digits, called the Organizational Unique Identifier, represent the manufacturer of the device. To find the IP address, click on the TCP/IP tab. Generally, this will either be Built-In Ethernet or Airport. Under 'Show:', select the network interface that you want the IP/MAC address for. Click on 'Network' in the System Preferences panel. The MAC address, or media access control address, is a 12-digit hexadecimal number assigned to each network device. Go to the Apple Menu, then select System Preferences. Let me walk you through the simple steps to find the MAC address on your MacBook. For instance, configuring a network router to filter devices or troubleshooting that network requires the MAC address.
UPDATE: Starting mac on safe mode let me go to internet but after I restarted it normally I was having the same problem.So yeah now I can get to internet but using mac on safe mode isn't really an enjoyable experience with its flashy screen.Knowing how to find the MAC address on your MacBook could sometimes be useful. Is there not a simple fix to this?ĮDIT: sometimes and atm it tells me that I'm connected to the modem and tells the IP addres (that isn't 169.xxx.) but I still can't get to internet. Trying to configure ipv4 manually by using info I got from my ipad after connecting ipad to the modem (setting IP one or more numbers higher than on iPad)Īnd prolly other stuff I already forgot. Writing some script to terminal (no idea what was it)ĭeleting the wi-fi from the side panel at network preferences
Rebooting both devices (modem and macbook)
I have tried to fix this issue by doing stuff that have worked for others Other devices have connected to those without problems. I've tried to connect to 3 different modems and haven't had success with any of those. Recently my macbook air haven't been able to connect to internet or even find the correct IP address.
