Troubleshooting intermittent or no Wi-Fi connection

1. Monitor Link Rate and Signal Strength:

Check the link rate and RSSI/Signal Strength of your device via the router/AP node in WebUI or Aginet APP.
If the link rate is low or the RSSI/Signal Strength value is too low, this could cause an unstable connection. Try moving the device closer to the router/AP node and monitor again.
Wi-Fi Signal Strength value rating table as below:

Signal Strength (dBm)	Rating	Description
-30 to -50	Excellent	Perfect or near-perfect signal strength. Online activities can be carried out seamlessly without fear of disconnection.
-51 to -60	Good	High signal strength. Good enough for most online activities, including high-intensity gaming and video streaming.
-61 to -70	Fair	Decent signal strength. Sufficient for everyday tasks like emails and Web surfing.
-71 to -80	Poor	Low level of connectivity. There may be occasional disconnects and data loss.
-81 or lower	Very weak	Near-complete disconnection. Data loss and mid-task disconnections are frequent.

2. Address Blind Spots:

If there are blind spots due to the main router’s coverage limitations, consider adding another mesh node to extend the wireless coverage.
Place the router/AP node in an area with fewer obstacles, avoid placing it on the floor, and place it high off the ground to minimize transmission interference.

3. Check Backhaul Link Rate:

Verify the wireless backhaul link rate/signal strength between the router and the wireless mesh AP node. If it’s too low, adjust the node’s placement to ensure a more stable link rate/signal strength.
Recommendation for backhaul signal strength: Web UI displays 4 bars and above, and Aginet APP displays green color signal strength.

Aginet APP:

4. Wired Connection Test:

Connect the device directly to the ONT modem to check for any drop or instability in the internet connection from the backhaul.
Also, check the LED status of the router/ONT modem.
If issues persist, report the unstable internet backhaul to your service provider.

5. Unique SSID Names:

Avoid using the same Wi-Fi SSID name for the separate 2.4GHz, 5GHz, 6GHz, and MLO Wi-Fi bands.

6. Check Power Saving Mode:

If devices are in power-saving mode, disable them and monitor their performance, as this might be causing the issue.

7. Channel Congestion:

For potential environmental with 2.4GHz Wi-Fi channel congestion, try switching to another channel with a lower channel width in WebUI or Aginet APP settings and monitor again.
Channel congestion status can be checked via third party APP that is related with Wi-Fi performance, and it will show the status as below, for example:

Channel Health page.

8. Compatibility Issues:

Some older devices may not be compatible with BE mode and higher security encryption standards. Adjust the Wi-Fi band settings to 802.11 b/g/n/ac/ax (without BE) and use lower security, such as WPA2-PSK only.
