# Filter scan results

> Filter wireless network scan results in WiFi Explorer Pro for Windows.

In *WiFi Explorer Pro for Windows*, 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 Pro for Windows*, including filtering by keywords, specific network attributes, or information element fields. *WiFi Explorer Pro for Windows* also offers [pre-defined and custom filters](/wifiexplorerpro-windows/filter-networks-using-custom-filters).

***

## 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%**.
* 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**), BSS Fast Transition (use **ft**), Hotspot 2.0 (use **hs**), and Dynamic Transmit Power Control (use **dtpc**). 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 Pro for Windows* and are identified with the prefix **dot11.net.**, as shown in the table below. For example, to show only networks with a minimum basic rate of 11 Mbps or higher, use the filter **dot11.net.min\_basic\_rate >= 11**.

<Tip>
  Right-click a field in the *Networks Table* and choose **Apply as Filter** to filter by the selected network attribute, or **Apply as Filter and Negate** to filter by everything that doesn't match it.
</Tip>

<Note>
  If you filter only by the attribute name, for example, **dot11.net.country\_code**, then only the networks that include this attribute are displayed.
</Note>

## Filter networks using information element fields

Besides network attributes, you can also filter networks by specific information element fields. The prefix **dot11.** identifies information element fields (except for **dot11.net**, which identifies network attributes).

<Tip>
  There are more than 650 information element fields you can use to filter networks in *WiFi Explorer Pro for Windows*. The auto-complete function of the **Filter** field will help you navigate the list and find the specific information element field you need.
</Tip>

<Tip>
  Select a network and right-click a field in the *Advanced Details* view, then choose **Apply as Filter** to filter by the selected information element field, or **Apply as Filter and Negate** to filter by everything that doesn't match it.
</Tip>

***

### Compare values

You can use the following operators to compare values when filtering using network attributes or information element fields:

| 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       |

<Note>
  If the value you're comparing contains spaces, then you must use quotation marks. For example, **dot11.net.ssid == "Guest Network"**.
</Note>

<Note>
  It is optional to include the units (MHz, GHz, dBm, etc.) when comparing numerical values. For example, the filter **dot11.net.signal > -65** is equivalent to **dot11.net.signal > "-65 dBm"**.
</Note>

### 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**.

<Tip>
  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.
</Tip>

### 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**.
