How to check connected devices to a Siretta Wi-Fi Router.
Steps for checking connected devices: –

1. Access router web page (GUI)
2. Navigate to the device list, you will be presented with the screenshot below.

 

3. Screenshot above shows connected devices with their MAC Address, IP address, Name, RSSI, Signal Quality Indicator and TX/RX Rate displayed.
How to control access to a Siretta Wi-Fi Router Network
Wireless Client Filter option from the Siretta Wi-Fi Router will allow admin to control access to a Wi-Fi network by restricting or allowing connection by using MAC addresses of the connected devices.
There are three Modes for Client Filter: –
• Disable Filter – Any device can be connect to a Wi-Fi Network using user name and password (“Training”, “Training”).
• Permit Only the Following Client – Only Clients with defined MAC address (See step 2 above) will be allowed to connect to a network
• Block the following client – Any device can connect except for the listed MAC addresses.
Example below shows only Galaxy-S9 and OMARI-DELL are allowed to connect to the “Training” Wi-Fi network.
Setting Multiple Wi-Fi Networks using Siretta Wi-Fi Router
Up to 4 x Wi-Fi networks can be configured on the same router using the similar procedure as above with different network names. Screenshots below show MultiSSID (Training and router-Wi-Fi (1-3)).
1. Wireless Network 1 (Training – Enabled).
2. Wireless Network 2 (router-wifi1 – Disabled).
3. Wireless Network 3 (router-wifi2 – Disabled).
4. Wireless Network 4 (router-wifi3 – Disabled).
Surveying Neighbourhood Wi-Fi Networks using Siretta Wi-Fi Router
Wireless Survey option will allow admin to see the parameters (i.e. RSSI, Noise, Signal Quality and used channel) of other Wi-Fi Networks within range. When Wireless Survey is initiated, it will return results at specified time as seen below.

This will help customers during Wi-Fi network configuration in to avoid interferences from Wi-Fi Networks within range.

Wireless Advanced Settings
The Wi-fi advanced settings can be done by navigating to: –

1. WLAN
2. Advanced Wireless
3. Enter the parameters per your network requirements.
4. Below is the screenshot showing Wireless Advanced Settings

Definition of terms used in Wi-Fi Advanced Settings:
Afterburner – (Auto, Enabled, Disabled*) – Speedbooster
AP Isolation – (Disabled*, Enabled) – Disabled option client devices will be able to communicate with the router but not with each other in the network. Enabled Option will allow Clients to communicate with the router and with each other in the network.
Authentication Type – (Auto*) – Auto allows either Open System or Shared Key authentication to be used.

Transmission Rate – (Auto*,1Mbps,2Mbps,5.5Mbps,6Mbps,9Mbps,11Mbps,12Mbps,18Mbps,24Mbps,36Mbps,48Mbps, 54Mbps) – The rate for data transmission should be set depending on the speed of your wireless network.
Interference Mitigation – (None*, Non-WLAN, WLAN Manual, WLAN Auto, WLAN Auto with Noise Reduction)
None- No other electronic devices around the router that may cause an interference.
Non-WLAN – if the primary source of interference in your area are non-WLAN electronic devices, such as cordless phones.
WLAN – if the primary source of interference in your area are WLAN electronic devices.
WLAN Manual activates interference mitigation against other Wireless LAN devices.
WLAN Auto is similar to WLAN Manual above.
WMM – (Auto*, Disable, Enabled)- Is a Wi-Fi certification based on the IEEE 802.11e standard.
No ACK – (Disabled*, Enabled)- When Enabled Frames sent are not acknowledged. When Disabled Frames will be acknowledged.
APSD Mode – (Disabled, Enabled*)- Automatic Power Save Delivery is a power management method where data rates are roughly the same in both directions.
Wireless Multicast Forwarding – (Disabled*, Enabled) – Is the way of forwarding traffic on the wireless network.
When Enabled router will be transmitting traffics only to the targeted members of the multicast.
* Default.
