Here is one that caught me by surprise and several of our customers as well. MikroTik’s default configuration for devices with wireless has changed. There is now WPA/WPA2 security on the wireless connection. You will need to enter the serial number of the device as the key to get wireless access to the device the first time. The serial number should be entered with capital letters and no spaces and it is found on the sticker on the bottom of the device. In this example the key is 4588026E58E1.
My advise? Log in via ether2, and remove the default configuration. Then use Quickset to reconfigure your way!
