# 2.4GHz WiFi Network

TankMate WiFi sensors can only connect to a 2.4GHz WiFi network. Most modern routers have the ability to broadcast in 2.4GHz and 5GHz. 

### Option 1: Dedicated 2.4GHz Network

Some WiFi networks will have two different SSIDs:

* MyWiFiNetwork (likely a 2.4GHz network) **->** **use this one!**
* MyWiFiNetwork**\_5g** (likely a 5GHz network)

### Option 2: Combined 2.4 / 5GHz Network

This is common for **newer routers**. In this case you will only be able to see **one SSID**, e.g.

* MyWiFiNetwork

{% hint style="info" %}
When only **one SSID** is shown - this will most likely be **capable** of running 2.4 / 5GHz simultaneosly, and should be suitable for use with a TankMate sensor.

However, if you experience issues connecting - see tips below to **check that the 2.4GHz radio is enabled.**&#x20;
{% endhint %}

### **Check that the 2.4GHz radio is enabled**

Access your **router's admin panel** to check the setting for your wireless network

* Look at the **label on the back** of your router. This should display the **address**, **user name** and **password** used to log in to your router settings
* e.g. a [Spark Smart Modem](https://www.spark.co.nz/help/internet/broadband-help/spark-smart-modem-support/log-into-modem/) would use: 192.168.1.254; admin; admin
* From your PC:
  * Open any **web browser** such as Chrome, Firefox, Edge
  * In the address bar, type in the **router address** (e.g. 192.168.1.254) and press enter
* Under your wireless network settings (**WLAN**) - check that the **2.4GHz option** has been turned on&#x20;

{% hint style="success" %}
**TIP: Create a Guest Network on 2.4GHz**

If you are having issues connecting to your main WiFi network, open your **router admin panel**, and turn on the **guest network** - which is usually a **standalone 2.4GHz** network. Most routers support this.

**Note:** after setting this up, you will need to connect your phone to it temporarily (iPhone only) to be able to connect the TankMate sensor to this new network!

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://tankmate.gitbook.io/tankmate/wi-fi-connectivity/2.4ghz-wifi-network.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
