How to Change the Wi-Fi Password and Settings on a TP-Link Mobile Wi-Fi Router

This guide provides step-by-step instructions for changing the wireless settings on your TP-Link Mobile Wi-Fi Router, including the SSID, password, and channel. To change your Wi-Fi password on a TP-Link from mobile or desktop, the steps vary slightly between 3G/4G and 5G models. Both scenarios are covered below, with configuration options available via the tpMiFi app, Tether app, or the web management page at http://tplinkmifi.net.

Key Takeaways

• Wireless settings on a TP-Link Mobile Wi-Fi Router — including the Wi-Fi name (SSID), password, and channel — can be changed via the tpMiFi app, Tether app, or web management page at http://tplinkmifi.net.
• For 3G/4G models, the tpMiFi app handles SSID and password changes. Advanced settings, such as channel selection, require the web management page.
• For 5G models, wireless settings can be changed via the device screen, the Tether app, or the web management page.
• The default SSID for TP-Link Mobile Wi-Fi Routers is TP-Link_XXXX, where XXXX represents the last four characters of the device's MAC address.
• Setting the wireless channel to "Auto" lets the device automatically select the clearest channel and is recommended for most users.

How to Change Wireless Settings

• TWT

Target Wake Time allows 802.11ax routers and clients to negotiate their periods for transmitting and receiving data packets. Clients wake up only during TWT sessions and remain in sleep mode for the rest of the time, significantly extending their battery life.

• Wireless Network Name (SSID)

SSID is the name of your wireless network. The default SSID for this device is TP-Link_XXXX (where “XXXX” represents the last four characters of its MAC address). You can customize it with up to 32 case-sensitive characters, after which it will appear in your device’s list of available networks.

• Wireless Band: 2.4GHz | 5GHz | 6GHz

Select 2.4 GHz, 5 GHz, or 6 GHz to change the corresponding settings. Different models support different bands.

• Wireless Radio

Tick this checkbox to turn on the wireless network.

• Wireless Mode

Wireless Mode selects the Wi-Fi protocol for your network band. Choose 11bgn mixed for 2.4 GHz or 11a/n/ac mixed for 5 GHz for broad compatibility, or select a specific mode (e.g., 11n only) to match your device’s wireless adapter for optimal performance.

• Wireless Security

Security Mode offers two options: Unsecured (open network) or WPA-PSK/WPA2-PSK, which provides strong encryption using a pre-shared password and is recommended for most home and small office users.

• Channel Width

Select a channel width (bandwidth) for the wireless network. If you are not sure, select Auto.

• Channel

Wireless Channel sets the specific frequency for your Wi-Fi band. Select “Auto” to let the device automatically choose the clearest channel, or manually select a channel only if you experience interference from nearby networks.

• Wi-Fi Power

Select either Balanced, Standard, or Boost to specify the data transmit power. The default and recommended setting is Standard. Changing the Power Saving Mode will also change the Wi-Fi Power.

• Wi-Fi Sleep Time

If no client is associated with the Wi-Fi for a certain period, the Wi-Fi will automatically be disabled. However, pressing the switch will turn it on again.
