how to connect Router to my new laptop?

[Rose Einstein]

My wireless Netgear AR65 router was connected to my PC with wire to secure my data. After buying  Laptop I couldn't find any socket at both sides to make  the router connected.
Any solution or should I buy new laptop?

Laptops often connect with with wireless.
For Windows 10 you would connect to a wireless network this way:
To access the network settings, click the "Network settings" link (refer to the previous image). Or launch the Settings app and navigate to "Network & Internet". In the Wi-Fi section, you'll find all the wireless networks available to you (this is new to Windows 10), which is the same list you see in the system tray....

What is the make and model of your laptop?  Did you not know its specifications when you bought it?
