You have just set up a new wireless network at your house, and you want to determine whether your Linux laptop has connected to it and obtained a valid IP address. What command will give you the information you need?
The command that can give you the information you need is "ifconfig". By running this command on your Linux laptop, you will be able to see the network interfaces, including the wireless interface (usually named wlan0 or wifi0), and check if it has obtained a valid IP address.
To determine if your Linux laptop has connected to the wireless network and obtained a valid IP address, you can use the following command:
```
ifconfig
```
