No internet after changing router mac address

[Danijel Berkesh]

Yesterday i entered my modem/router (tp-link td8816) configuration and changed its mac address. After the change i lost my internet connection(internet light on modem is off and yellow exclamation mark is on the icon in windows) Even when i change the mac address back to its default number, there is still no connection!! I tried a hard reset of my tp-link, still nothing. Here is the system log from my routers configuration:
"1/1/2000 0:4:5> Last errorlog repeat 10 Times

When you say you did a "hard reset" do you mean you did a factory reset -> holding in the reset button with a paper clip for 5+ seconds?

Since i allowed mac spoofing on my router it was neccessary to type in my ISP username and password within the PPoE/PPoA settings. After i did this, internet led turned immediately on and connection was up. Problem solved
