Problem Description

when the user uses internet service via Wi-Fi. interruption happens, and many packets get dropped.


Handling Process

1- Do ping test to public IP (Google for example) and ping from laptop to ONT at the same time.

we found the ping to ONT also has packet loss.

2- connect laptop to ONT by LAN cable and do ping test.

No Packet loss.

3- Observe the performance for some days using two laptops one connected via LAN cable, the other is connected via WiFi.

we found that laptop connected via WiFi suffers packet loss.

4- By checking ONT version, we found it's V3R13C00.

this version had issue with WiFi performance DTS2015080706827 optimized in later version.

5- by upgrading ONT to  R17C10SPC135 and observe.

6- after one week observation, the WiFi performance enhanced.

Root Cause
When sudden interference occurs in the Wi-Fi environment, the ONT Wi-Fi performance may decrease, and the ONT can resume the normal Wi-Fi performance automatically after a short period of time. The related algorithm is optimized to improve the Wi-Fi performance stability in later versions
Solution

【Resolution Summary】

After upgrade to R17C10SPC135, the issue is resolved
