I can't access to the router configuration page.

Hi everyone, I just purchased an LHG 18 KIT external router. I connected everything following the instructions. I put DHCP in AUTO on my network card. The problem is that I cannot access the router via web (VIA 192.168.188.1). It tells me that it is impossible to connect, as when there is no internet. The blue power LED and the second green LED are on (on the Antenna)… but not is there a way to connect to the router page. Does anyone know how to resolve the problem?
Thanks for any response.
Have a nice weekend

What IP address did your PC get ?
Could be it should be 192.168.88.1 for accessing the router (though user manual does mention 192.168.188.1).

Thanks for the reply.
I also tried entering the IP address 192.168.88.1 but it still gives me an error : it is not possible to connect to the requested page.

P.s.
via PROMPT/ipconfig under ipv4 it gives me the IP of my old connection, ipv4 :169.254.39.150. and not 192.168.188.1 which is that of the router
