If you are not able to connect; 1. Check the Laptop IP address, I hope it is something in the series of 192.168.x.x. 2. This IP is obtained from the Internet modem. 3. You can login to the Modem and see the IP address provided by the modem, you should find the AP's IP there. 4. So the AP IP should also be in the same range as Laptops, if you are not able to login to the modem, you can try different IPs in the browser (https://192.168.x.x) and see if you can get access to the AP.
