WiFi Hotspots
The mobile router features an integrated WiFi access point, enabled by default, that allows connecting multiple wireless devices to access the mobile broadband connection.
Wireless Overview
After logging into the router, go to "Network > Wireless." The Wireless Overview page lists the WiFi configuration section of the physical radio. You can configure the WiFi hotspots and set up a WiFi relay.
(radio0) Generic MAC80211 802.11bgn is the WiFi4 (2.4GHz) WiFi network
radio0 - Represents the physical wireless radio on the router
SSID | Mode: Master - The primary WiFi (main & guest) hotspots hosted by the router
SSID | Mode: Client - When configured, displays any relayed/repeated WiFi networks
Associated Stations - Lists the currently active WiFi networks, client devices connected to them, and their status.
WiFi Settings
Click the "Edit" button on the WiFi SSID row to enter the configure section.
Cellular-WiFi-xxxxxx is the main WiFi hotspot. Guest-WiFi-xxxxxx is the Guest WiFi hotspot isolated in a separate subnet.
Note: "xxxxxx" indicates the MAC address of the WiFi AP module.
Device Configuration
Tab: General Setup
Monitor the WiFi hotspot status and configure general WiFi settings as below. Keeping the default settings is recommended to avoid conflicts.
Operating Mode - Leave 802.11n standard (N mode) as default for maximum compatibility.
Channel - Use the default Auto channel selection to let the router choose an unused channel. Or, if setting a manual channel, choose a lower channel <11 to ensure legacy device compatibility after setting the country code.
Operating Width - Default 20MHz width instead of 40MHz helps avoid interference in dense WiFi environments.
Transmit Power - Leave it in "Auto" mode to let the router adjust within regulatory limits. The max transmit power may be restricted below 21dBm depending on the country code for legal compliance.
Tab: Advanced Settings
Additional WiFi hotspot options can be configured under the "Advanced Settings" tab. These levers allow fine-tuning performance in challenging RF environments but require advanced wireless expertise. Misconfiguration can severely impact connectivity.
Country Code - Select the appropriate country to ensure WiFi operates on legal frequencies and power levels.
Fragmentation Threshold - Packet size before link layer fragmentation. Lower settings can help noisy links. 2346 bytes is generally recommended.
RTS/CTS Threshold - Frame size threshold for RTS/CTS handshake. 2347 bytes is typically optimal.
Beacon Interval - Configure the packet broadcast frequency. Lower times increase roaming support at the cost of throughput. Default 100ms is recommended.
Wi-Fi SSID & Password
Scroll down to the "Interface Configuration" section to edit the WiFi SSID (WiFi hotspot name) and WiFi password.
Tab: General Setup
Mode - Leave as Access Point
ESSID - Enter the WiFi hotspot name (SSID) for the WiFi hotspot. It is recommended not to include spaces or special characters.
Network - Leave as the default LAN network
Hide ESSID - Enable this option to disable SSID broadcast.
WMM Mode - WiFi Multimedia is an automated way of handling Quality of Service (QoS). Turn it off for more compatibility with legacy WiFi devices.
Tab: Wireless Security
Next, click the "Wireless Security" tab to set up a WiFi password.
Encryption - Select the encryption method. Using "WPA2-PSK" or "Mixed WPA/WPA2" encryption with a strong password is highly recommended to prevent unauthorized access.
Cipher - The recommended default is "Auto."
Key - Enter and confirm a password (at least eight characters) that clients will use to connect. Do not leave this option empty after choosing the "Encryption" method above.
Finally, click the "Save & Apply" button to apply the new settings. The WiFi hotspot will reboot in 2-3 minutes to apply the updated settings.
Then, refresh network scans and reconnect your devices to the newly renamed/secured wireless network.
WiFi Relay
The EZR23T router can be configured in WiFi client mode to connect to an existing WiFi hotspot as a client device. When joining another WiFi network, the router will obtain internet connectivity through that target wireless access point.
