Q&A for How to See Who Is Connected to Your Wireless Network

You could download your router's management app and then view the connected devices list on your phone. Check your router's setup guide to see which app you need to download.

They will show up on the hotspot's device list. You may have to log into it, or if it is on your phone, it should be displayed in your phone's menu.

It's possible that it is a device that you don't remember. But it's also possible that you have a network intruder. I would recommend changing your Wi-Fi password (make sure to use WPA2), and then reconnecting all of your devices.

You can Google "MAC address lookup", and then type in the MAC address into the site. Keep in mind that you can only retrieve the wireless card's manufacture information from the MAC address. Specific device information cannot be provided.

You can look up the device's MAC address to find the device's (or wireless card's) manufacturer, and you can view the device name to see if it has any information. But you would have to find the actual device connected to learn any more about it.

If they are connected to your Wi-Fi network, then they will be able to tell since they will be kicked off. Otherwise, no, they cannot tell. If you are still getting new devices after you change your Wi-Fi password, and you are sure that they are not yours, then you can read How to Secure Your Wireless Home Network for help.

First, I want to let you know that Ethernet is actually faster than Wi-Fi, so I wouldn't recommend this. But if you still want to do it, then you can check if your desktop has a Wi-Fi card. You can easily check this by clicking on the Ethernet icon (it looks like a PC with an Ethernet cable in the bottom right corner of the screen), and seeing if there are Wi-Fi networks listed. If you see this, then just connect to a network. If you cannot, then you need to buy a Wi-Fi adapter for your PC. You can easily buy USB adapters from a store or online. Once you have one, follow the steps that come with it to set it up.

You can change your password to kick them out. You can read How to Add a Password to Your Wi-Fi for steps on how to change it. (I know it says how to add one, but it also tells you how to change it.)

Yes, many routers come with apps to manage them, or you can use your phones browser to log into their management interface. The way to do this varies by router, but the manual that comes with it will tell you how to do it.

No, it won't. If you have the MAC address, you can search online for "MAC address lookup", and then enter the MAC address into the site, and the site will tell you the brand that made the Wi-Fi adapter for the device, but you can't get any more info than that, unfortunately.

If they are not being shown in the router, then they are not connected. It's likely that you are dealing with another network problem. You can read How to Fix Common Computer Network Issues for help.

Yes, a Linux network mapper would work just as well as a Windows or Mac one.

You would have to set up remote access to your Wi-Fi router to do this. How to do this varies by router, and should be described in the manual. Please note that by doing this, you could create security issues, so do this with caution.

No, they would have to be in range to connect to the Wi-Fi network. The average range of a Wi-Fi network is 150 feet or 45 meters. However, they will still have the password saved in their device, so if they come back in range, they can still connect. If you want to prevent them from reconnecting, then you need to change your password. You can read How to Change Your Wi Fi Password for steps on how to do this.
