DLink wlan amplifier DAP1520 does not connect to the laptop (windows10)?

I use for a while the dlink wlan amplifier and was always satisfied, I've got a laptop and I wanted to connect him with it, which he does in principle, however, it always indicates

Connected, no internet

What could be the reason and someone knows a solution?

Your repeater is not connected to the router, so it emits a wireless network that has no connection to the Internet (ie only one network). Repeater restart, you've probably already tried.

Check with another wireless device (such as a smartphone) if it can't connect to the Internet when connected to the repeater.

If it is not synonymous with a smartphone, reconnect the repeater to the router, according to the installation instructions of the repeater. The easiest way is with the WPS-keys (on the router and on the repeater press the WPS-key, according to the instructions).
