Windows 10 Wireless Network Filter: Add or Remove Guide

This guide shows you how to control which Wi-Fi networks your Windows 10 PC can connect to by adding or removing them from the wireless network filter. This is useful for restricting access to specific networks (like a school or office) or for blocking unwanted or unsecured connections. You’ll need administrator rights on the computer to make these changes.

What You’ll Need

• A Windows 10 PC with administrator privileges.
• The exact name (SSID) of the wireless network you want to add or remove.
• Access to the Windows Settings app (available on all supported versions of Windows 10).

Step-by-Step

1. Open Windows Settings. Click the Start button (Windows logo) in the bottom-left corner, then click the gear icon (Settings). Alternatively, press Windows key + I on your keyboard.
2. Go to Network & Internet. In the Settings window, click on Network & Internet.
3. Open Wi-Fi settings. In the left-hand sidebar, click Wi-Fi.
4. Access advanced settings. Scroll down the Wi-Fi page and click Manage known networks. This opens a list of all networks your PC has connected to before.
5. Open the filter settings. On the “Manage known networks” page, look for a link or button labeled Network filter (it may appear as a small text link below the list). Click it. This opens a new window titled “Network filter.”
6. Add a network to the filter. In the “Network filter” window, you’ll see two sections: Allowed networks and Blocked networks. To add a network, click the Add button in the section you want (Allowed or Blocked). A small dialog box will appear.
7. Enter the network name. Type the exact SSID (network name) of the Wi-Fi network you want to filter. It must match the network’s broadcast name exactly, including capitalization and spaces. Click Save.
8. Remove a network from the filter. To remove a network, find it in the list under either “Allowed networks” or “Blocked networks.” Click on the network name to select it, then click the Remove button. Confirm if prompted.
9. Close the window. Once you’ve made your changes, click Close (or the X in the top-right corner) to exit the Network filter window. Your changes take effect immediately.

Common Mistakes

• Typing the wrong network name: The filter is case-sensitive and requires the exact SSID. A common mistake is typing “HomeNetwork” when the actual name is “homenetwork.” Double-check the name in your Wi-Fi list.
• Confusing “Allowed” with “Blocked”: Adding a network to “Allowed” does not block it; it only permits it. Adding to “Blocked” prevents connection. Make sure you’re adding to the correct list.
• Forgetting to save: If you type a name and close the dialog without clicking Save, the network won’t be added.
• Filtering a network you’re currently connected to: If you block the network you’re currently using, your connection will drop immediately. You’ll need to reconnect to another network to undo it.
• Assuming the filter hides networks: The filter only controls whether your PC can connect; it does not hide the network from the list of available Wi-Fi networks.

Tips

• Use the filter for security: Block open (unsecured) networks you don’t trust, or restrict your kids’ PC to only your home network.
• Check the network name first: Before adding, connect to the network once (or look at the Wi-Fi list) to copy the exact SSID.
• Use it for public Wi-Fi: If you’re in a hotel or airport, you can add the public network to “Allowed” to prevent your PC from auto-connecting to other, less secure networks.
• Remember the filter is per-device: This filter only applies to the PC you’re setting it up on. Other devices on the same network are unaffected.
• Test after adding: After adding a network to “Blocked,” try to connect to it manually. You should see a message that the network is blocked by the system administrator.

Troubleshooting

• I can’t find the “Network filter” link: This option is available in Windows 10 version 1803 and later. If you don’t see it, check your Windows version by going to Settings > System > About. If you’re on an older version, update Windows. If you’re on a managed (work/school) device, the option may be hidden by your IT administrator.
• The network I added doesn’t appear in the filter list: Ensure you clicked Save after typing the name. Also, verify you’re looking in the correct section (Allowed vs. Blocked).
• I blocked a network but I can still connect to it: This can happen if the network name you typed doesn’t exactly match the broadcast SSID. Check for typos, extra spaces, or wrong capitalization. Also, make sure you saved the entry in the “Blocked” section, not “Allowed.”
• I removed a network from the filter, but it’s still blocked: Try restarting your Wi-Fi adapter (turn Wi-Fi off and on) or restarting your PC. If the issue persists, check if the network is also blocked by Group Policy (if it’s a work/school PC).
• I can’t add a network because the “Add” button is greyed out: This usually means you don’t have administrator rights on the PC. Try logging in with an administrator account, or contact your system administrator.
• The filter window is empty even though I have known networks: The filter is independent of your known networks list. You must manually add networks to the filter; it doesn’t populate automatically.

Frequently Asked Questions

1. Does the filter affect networks I’ve already connected to? Yes, the filter applies immediately. If you block a network you’ve previously connected to, your PC will disconnect from it and won’t reconnect until you remove it from the blocked list.
2. Can I filter networks by signal strength or security type? No, the filter only works by network name (SSID). You cannot filter by signal strength or security protocol (WPA2, WEP, etc.) using this tool.
3. Will the filter prevent my PC from seeing a network? No, the network will still appear in your list of available Wi-Fi networks. The filter only prevents your PC from connecting to it.
4. Is there a limit to how many networks I can add to the filter? There is no documented limit. You can add as many network names as you need.
5. Does this filter work for Ethernet connections? No, the network filter only applies to Wi-Fi (wireless) connections. Wired Ethernet connections are not affected.
6. Can I use this filter to prioritize one network over another? No, the filter only allows or blocks connections. To prioritize networks, you need to adjust the “Wi-Fi sense” or adapter settings, which is a different process.
