# Filter scan results
> Filter wireless network scan results in WiFi Explorer.
In *WiFi Explorer*, you can quickly filter scan results to help diagnose or troubleshoot specific wireless networks or environments.
There are many ways to filter scan results in *WiFi Explorer*, including filtering by keywords or specific network attributes. *WiFi Explorer* also offers advanced filter options such as [pre-defined and custom filters](/wifiexplorer/filter-networks-using-custom-filters), [automatic filters](/wifiexplorer/filter-networks-using-automatic-filters), and [keyboard shortcuts](/wifiexplorer/filter-networks-by-signal-strength-using-keyboard-shortcuts).

## Filter networks using keywords
You can filter networks by name (SSID), BSSID, channel, signal strength (RSSI), annotations, mode, vendor, access point name, band, country code, security, encryption type, or whether certain capabilities are supported using the **Filter** field.
* To filter networks by name (SSID), annotations, vendor, or access point name, type the text in the **Filter** field. If you need to filter using an exact match, use quotation marks for the keywords, e.g., **"ABC School."**
* To filter networks by BSSID, type either :XX or XX: where XX is an octet of the BSSID. You can also extend the text with more octets (e.g. XX:XX, XX:XX:XX) to search for more specific BSSIDs.
* To filter networks by signal strength (RSSI), type a comparison operator (`<`, `>`, `<=`, or `>=`) and the signal strength level in the **Filter** field. For example, to display only networks with a signal strength greater than or equal to -65 dBm, type **>=-65**. To use signal strength as a percentage, type **>=50%**.
You can also permanently filter and hide networks with weak signals by adjusting the scan operation's sensitivity. To change the sensitivity, choose *WiFi Explorer* > *Settings* > *General*, then select the desired scan sensitivity level.
* To filter networks by channel number, type the channel number in the **Filter** field. You can also specify ranges, for example, the filter **2-5** shows all networks on channels 2, 3, 4, or 5.
* To filter networks by band, type the band (e.g., **2.4GHz**, **2.4ghz**, **24ghz**, **5ghz**, **6ghz**) in the **Filter** field.
* To filter networks by generation, use **wifi4**, **wifi5**, or **wifi6**.
* To filter networks by mode, type the letter or letters that identify the mode: **a**, **b**, **g**, **n**, **ac**, **ax**, or **be**. You can also prefix the letter(s) with 802.11, 80211 or just 11. For example, type **11b** to display only networks that support 802.11b, or **ax** to display only networks that support 802.11ax.
* To filter networks by security or encryption type, enter the acronym for the security or encryption type in the **Filter** field. For example, type **WPA2** to display only networks that are configured with WPA2.
* To filter networks by capability, enter the capability in the **Filter** field. The following capabilities are supported: Wi-Fi Protected Setup (use **wps**) and BSS Fast Transition (use **ft**). For example, type **wps** to display only networks that support WPS.
* To filter networks by hidden SSID, enter **hidden** in the **Filter** field.

## Filter networks using specific network attributes
You can also filter networks by specific attributes. These attributes map to available columns in *WiFi Explorer* and are identified with the prefix **dot11.net.**, as shown in the table below. For example, to show only networks with a US country code, use the filter **dot11.net.country\_code == US**.
Control-click a field in the *Networks Table* and choose **Apply as Filter** to filter by the selected network attribute or **New Filter** to create a new [custom filter](/wifiexplorer/filter-networks-using-custom-filters) based on it. Control-click and press Option to choose **Apply as Filter and Negate** or **New Filter and Negate** to negate the selected filter.
If you filter only by the attribute name, for example, **dot11.net.country\_code**, then only the networks that include this attribute are displayed.
| Attribute | Description |
| --------------------------- | ---------------------------------------------- |
| `dot11.net.annotations` | Annotations |
| `dot11.net.band` | Frequency band (2.4 GHz, 5 GHz, or 6 GHz) |
| `dot11.net.basic_rates` | Supported basic rates (Mbps) |
| `dot11.net.beacon_interval` | Beacon interval (milliseconds) |
| `dot11.net.bssid` | BSSID |
| `dot11.net.center_freq` | Center frequency (MHz) |
| `dot11.net.channel` | Channel |
| `dot11.net.channel_util` | BSS Load channel utilization (%) |
| `dot11.net.channel_width` | Channel width (MHz) |
| `dot11.net.country_code` | Country code |
| `dot11.net.ap_name` | Access point name |
| `dot11.net.fast_transition` | Fast BSS transition |
| `dot11.net.generation` | Generation (4, 5, or 6) |
| `dot11.net.max_rate` | Maximum supported rate (Mbps) |
| `dot11.net.min_rate` | Minimum supported rate (Mbps) |
| `dot11.net.mode` | Network mode (a/b/g/n/ac/ax/be) |
| `dot11.net.noise` | Noise (dBm) |
| `dot11.net.protection_mode` | HT protection mode |
| `dot11.net.security` | Security mode |
| `dot11.net.signal` | Signal strength (dBm) |
| `dot11.net.snr` | Signal-to-noise ratio (dB) |
| `dot11.net.ssid` | Network name (SSID) |
| `dot11.net.stations` | BSS Load station count |
| `dot11.net.streams` | Number of spatial streams |
| `dot11.net.type` | Network type (Ad-Hoc, Mesh, or Infrastructure) |
| `dot11.net.vendor` | Vendor |
| `dot11.net.wps` | Wi-Fi Protected Setup status |

### Compare values
You can use the following operators to compare values when filtering using network attributes:
| Operator | Description | Value Type |
| -------- | --------------------- | ------------ |
| == | Equal | Number, Text |
| != | Not equal | Number, Text |
| \~\~ | Contains | Text |
| !\~ | Does not contain | Text |
| > | Greater than | Number |
| >= | Greater or equal than | Number |
| `<` | Less than | Number |
| `<=` | Less or equal than | Number |
If the value you're comparing contains spaces, then you must use quotation marks. For example, **dot11.net.ssid == "Guest Network"**.
It is optional to include the units (MHz, GHz, dBm, etc.) when comparing numerical values. For example, the filter **dot11.net.snr > 15** is equivalent to **dot11.net.snr > "15 dB"**.
### Combine multiple filters
You can combine filters using "**OR**" or "**AND**." For example, if you want to filter networks so that only 2.4 GHz networks with a network name (SSID) starting with *School* are shown, use the filter **24ghz AND School**. If you want to display only networks on channels 1, 6, or 11, use the filter **1 OR 6 OR 11**.
You can use parenthesis to group filter expressions and change the order of evaluation of the **OR** and **AND** operators. For example, the filter **(2.4GHz AND 40MHz) OR (5GHz AND 160MHz)** will show 2.4 GHz networks using a 40 MHz channel width or 5 GHz networks using a 160 MHz channel width.
### Negate filters
You can negate a filter with "**NOT**." For example, to list all networks that do not have the word *School* as part of their names, enter **NOT School**.
