[2026-3-3 | Equipment Troubleshooting] Addressing a Home Internet Connection Fault
Tplan
After the resident reported that their fixed broadband connection kept dropping, we arranged a same-day
on-site inspection by China Telecom.
The inspection confirmed that the fault was caused by a failed ONU (Optical Network Unit), commonly known as a fiber modem.
The ONU was therefore replaced with a new unit on site.
The connection stabilized after replacement, and internet access is now working normally.
