Hi
I'm using mikrotik routerboard 951 configured to generate
a username and password .
How can I configure TPlink TL-WA5210G access point to extend the WIFI coverage in my coffee shop
Best regards

Hi,

At first you need to go to Basic settings/Operation Mode/Select the AP mode and click save. Then go to Wireless/Wireless Mode and select Universal Repeater and specify the mac address of MikoTik device there or click on survey to find your MikroTik there in Ap List and click on Connect ten hit Save.

But the important note is the "tp link tl-wa5210g" support week security protocol(wep) on repeater mode.
I you use another mikrotik device you can us more secure protocol.
Best Regards,
