Change of MAC address

Hi, I changed my MAC address on Kali Linux successfully. However, after changing the mac address I didn’t have access to internet. Its normal ?
And if its what is the piont of changing it? Can someone explain it to me please?
Thank you

No, changing Mac address should not affect your Internet access unless you have your Mac address whitelisted in the router

Thank you Apruv, I never change the setting in the router. And when I change my mac addrees, I didn’t have access to the Internet in the Linux machine.
Its possible to be whitelisted as a default?

That maybe the case. I would say to check your router to see if you have DHCP Mac filtering on or not
