Some routers include a web based screen where you can see connected clients listed.

You'd need to block access at the router anyway.

My asus router has 2 network options , private and guest.

Here I have a whitelist of MAC addresses for PCs/phones I want to allow to connect to my private network with access to my NAS and printers etc and the guest network which only allows access out onto the internet relies on a passkey which I change periodically.

Suspending access by a device is handled by removing that devices MAC from the list.

You could have a blacklist option instead where you do the opposite and allow general access using the passkey but block that particular device by adding the MAC to the backlist.

It all depends on what your firmware for your router allows you to do.

I have used SoftPerfect Network Scanner : fast advanced network scanner to scan my network, it's free but it's up to you to figure out which one is WiFi.

SoftPerfect Network Scanner is a fast universal IPv4/IPv6 scanner with a modern interface and many advanced features. It is intended for both system administrators and general users interested in computer security. The program can ping computers, scan ports, discover shared folders and comes with flexible filtering and display options. It can retrieve practically any information about network devices via WMI, SNMP, HTTP, SSH and PowerShell.
In addition, you can scan for remote services, registry, files, performance counters and so on. The results can be exported to a variety of formats from XML to JSON.

Nirsoft has a tool Wireless Network Watcher - Show who is connected to your wireless network. It's also free and although I have not used it Nirsoft makes great free program's.

Description

Wireless Network Watcher is a small utility that scans your wireless network and displays the list of all computers and devices that are currently connected to your network.
For every computer or device that is connected to your network, the following information is displayed: IP address, MAC address, the company that manufactured the network card, and optionally the computer name.
You can also export the connected devices list into html/xml/csv/text file, or copy the list to the clipboard and then paste into Excel or other spreadsheet application.

Blacklisting MAC addresses is useless ---- the first thing most WiFi hackers do is clone the Mac Address of one of the computers already conneted. Also if someone tells you that hiding your SSID will stop WiFi hackers has no idea what they are talking about.

This is true , but blacklisting and a decent WPA2 password on the router is a reasonable and quick way to take precautions , the OP hasn't stated why he needs to block , it might just be a neighbour piggybacking on his broadband, not a hacker.

You can buy / get freeware software to scan your wifi , but you'll still need to block the connection on your router or a central access point to disconnect/block it.
