Is my computer wifi enabled

Is there a terminal command to verify if Wifi is enabled?

Since my laptop doesnt have a Wireless Network LED indicator, I want to know if there is a command to verify if it is on or off (I’m installing the wireless drivers, so I can’t tell if it is set on or off by seeing the list of wireless conections next to the clock)

Edit:

nmcli changed a lot (I am using 16.04) from its previous version. See the original answer below.

To see the connectivity status

$ nmcli general status STATE CONNECTIVITY WIFI-HW WIFI WWAN-HW WWAN connected full enabled enabled enabled enabled 

To see only wifi status

To see the active connection

$ nmcli connection show --active NAME UUID TYPE DEVICE VolCSe 5u6h4521-7k1p-20r3-3g4x-fg19his0j3s8 802-11-wireless wlp2s0 

There are some nice addlitions like, to get the available wifi network informations,

$ nmcli device wifi * SSID MODE CHAN RATE SIGNAL BARS SECURITY * VolCSe Infra 1 54 Mbit/s 73 ▂▄▆_ WPA2 Sach Infra 4 54 Mbit/s 55 ▂▄__ WPA1 WPA2 iKCP Infra 5 54 Mbit/s 24 ▂___ WPA2 TP-LINK_POCKET_3 Infra 1 54 Mbit/s 12 ▂___ WPA1 WPA2 

Note: I have used fictitious ssid and uuid info above.

Old answer:

You can use nmcli for this purpose. Open a terminal type in terminal,

You will have output like,

RUNNING STATE WIFI-HARDWARE WIFI WWAN-HARDWARE WWAN running connected disabled disabled enabled disabled 

See the third and fourth column which contains information of your interest.

If you want to be more specific only to wifi, then try in terminal,

it will show the wifi status only,

Setting up a wireless network in Windows

A wireless network at home lets you get online from more places in your house. This article describes the basic steps for setting up a wireless network and starting to use it.

Get the right equipment

Before you can set up your wireless network, here’s what you’ll need:

Broadband Internet connection and modem. A broadband Internet connection is a high-speed Internet connection. Digital Subscriber Line (DSL) and cable are two of the most common broadband connections. You can get a broadband connection by contacting an Internet service provider (ISP). Typically, ISPs that provide DSL are telephone companies and ISPs that provide cable are cable TV companies. ISPs frequently offer broadband modems. Some ISPs also offer combination modem/wireless routers. You can also find these at computer or electronics stores, and online.

Wireless router. A router sends info between your network and the Internet. With a wireless router, you can connect PCs to your network using radio signals instead of wires. There are several different kinds of wireless network technologies, which include 802.11a, 802.11b, 802.11g, 802.11n, 802.11ac, and 802.11ax.

Wireless network adapter. A wireless network adapter is a device that connects your PC to a wireless network. To connect your portable or desktop PC to your wireless network, the PC must have a wireless network adapter. Most laptops and tablets—and some desktop PCs—come with a wireless network adapter already installed.

To check whether your PC has a wireless network adapter:

1. Select Start , type device manager in the search box, and then select Device Manager.
2. Expand Network adapters.
3. Look for a network adapter that might have wireless in the name.

Setting up the modem and Internet connection

After you have all the equipment, you’ll need to set up your modem and Internet connection. If your modem wasn’t set up for you by your Internet service provider (ISP), follow the instructions that came with your modem to connect it to your PC and the Internet. If you’re using Digital Subscriber Line (DSL), connect your modem to a phone jack. If you’re using cable, connect your modem to a cable jack.

Positioning the wireless router

Put your wireless router somewhere where it will receive the strongest signal with the least amount of interference. For better results, follow these tips:

Place your wireless router in a central location. Place the router as close to the center of your home as possible to increase the strength of the wireless signal throughout your home.

Position the wireless router off the floor and away from walls and metal objects, such as metal file cabinets. The fewer physical obstructions between your PC and the router’s signal, the more likely that you’ll be using the router’s full signal strength.

Reduce interference. Some networking equipment uses a 2.4 gigahertz (GHz) radio frequency. This is the same frequency as most microwaves and many cordless phones. If you turn on the microwave or get a call on a cordless phone, your wireless signal might be temporarily interrupted. You can avoid most of these issues by using a cordless phone with a higher frequency, such as 5.8 GHz.

Securing your wireless network

Security is always important; with a wireless network, it’s even more important because your network’s signal could be broadcast outside your home. If you don’t help secure your network, people with PCs nearby could access info stored on your network PCs and use your Internet connection.

To help make your network more secure:

Change the default user name and password. This helps protect your router. Most router manufacturers have a default user name and password on the router and a default network name (also known as the SSID). Someone could use this info to access your router without you knowing it. To help avoid that, change the default user name and password for your router. See the documentation for your device for instructions.

Set up a security key (password) for your network. Wireless networks have a network security key to help protect them from unauthorized access. We recommend using Wi-Fi Protected Access 3 (WPA3) security if your router and PC support it. See the documentation for your router for more detailed info, including what type of security is supported and how to set it up.

Some routers support Wi-Fi Protected Setup (WPS). If your router supports WPS and it’s connected to the network, follow these steps to set up a network security key:

1. Do one of the following, depending on which version of Windows is running on your PC:
   • In Windows 7 or Windows 8.1, select Start, start typing Network and Sharing Center, and then choose it in the list.
   • In Windows 10, select Start , then select Settings >Network & Internet >Status >Network and Sharing Center.
   • In Windows 11, select Start, type control panel, then select Control Panel >Network and Internet >Network and Sharing Center.
2. Select Set up a new connection or network.
3. Select Set up a new network, then choose Next.

The wizard will walk you through creating a network name and a security key. If your router supports it, the wizard will default to Wi‑Fi Protected Access (WPA2 or WPA3) security. We recommend that you use WPA3 if you can, because it offers better security than WPA2, WPA, or Wired Equivalent Privacy (WEP) security. With WPA3, WPA2 or WPA you can also use a passphrase, so you don’t have to remember a cryptic sequence of letters and numbers.

Write down your security key and keep it in a safe place. You can also save your security key on a USB flash drive by following the instructions in the wizard. (Saving your security key to a USB flash drive is available in Windows 8 and Windows 7, but not in Windows 10 or Windows 11.)

Use a firewall. A firewall is hardware or software that can help protect your PC from unauthorized users or malicious software (malware). Running a firewall on each PC on your network can help control the spread of malicious software on your network, and help protect your PCs when you’re accessing the Internet. Windows Firewall is included with this version of Windows.

Connect a PC to your wireless network

1. Select the Network or Wifi icon in the notification area.
2. In the list of networks, choose the network that you want to connect to, and then select Connect.
3. Type the security key (often called the password).
4. Follow additional instructions if there are any.

If you have problems with your Wi-Fi network when using Windows 10, see Fix Wi-Fi problems in Windows for advanced troubleshooting info.

1. Select the Network icon in the notification area, then select the > icon next to the Wi-Fi quick setting to see a list of available networks.
2. Choose the network that you want to connect to, and then select Connect.
3. Type the security key (often called the password).
4. Follow additional instructions if there are any.

If you have problems with your Wi-Fi network when using Windows 11, see Fix Wi-Fi problems in Windows for advanced troubleshooting info.
