# Filter networks using automatic filters

> Filter networks using automatic filters in WiFi Explorer.

Automatic filters are dynamically generated based on the scan results. You can choose these filters from the left sidebar by selecting one of the items under each of the following categories:

| Category      | Description                                                                                                                                                                                                                                                                                                                  |
| ------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Network Name  | Shows a list of unique SSIDs in use by networks found during the scan. If one or more networks are hidden, then the value *Hidden Network* is used. When you select an item from this category, only the networks using the selected SSID are shown.                                                                         |
| Annotation    | Shows a list of unique annotations assigned to the networks found during the scan. Only the networks that match the selected annotation are shown when you choose an item under this category.                                                                                                                               |
| Mode          | Shows a list of unique 802.11 modes in use by networks during a scan. A mode can be, for example, 802.11a, 802.11b, 802.11b/g/n, etc. When you select an item from this category, only the networks that match the selected mode are shown.                                                                                  |
| Channel       | Shows a list of unique primary channels in use by networks found during the scan. When you select an item from this category, only the networks using the selected primary channel are shown.                                                                                                                                |
| Channel Width | Shows a list of unique channel widths in use by networks found during the scan. When you select an item from this category, only the networks using the selected channel width are shown.                                                                                                                                    |
| Security      | Shows a list of unique security modes in use by networks found during the scan. When you select an item from this category, only the networks using the selected security mode are shown.                                                                                                                                    |
| Access Point  | Shows a list of unique access points, identified by BSSID, found during the scan. If two or more networks using different BSSIDs belong to the same access point, then a *masked* BSSID is used to identify the access point. When you select an item from this category, only the chosen access point's networks are shown. |
| Vendor        | Shows a list of unique vendors from the networks found during the scan. When you select an item from this category, only the networks that match the selected vendor are shown.                                                                                                                                              |

<Tip>
  If you choose an automatic filter from the sidebar, you can refine the scan results further by typing other keywords in the **Filter** field.
</Tip>

## Negate automatic filters

You can negate an automatic filter by selecting the filter and pressing **Spacebar**. For example, if you choose *WPA2 (PSK)* from the *Security* category and press **Spacebar**, only networks that do not match the *WPA2 (PSK)* filter are shown. To revert the filter, press **Spacebar** again.

<Note>
  The prefix **\~** identifies a negated automatic filter, for example, *\~WPA2 (PSK)*.
