Hi everyone, I switched to Netplus three days ago. The speeds are great, but I’ve hit a roadblock that I’m trying to solve.
The Problem:The internet works perfectly as long as I am actively using it. However, if the router sits idle for about 1–2 hours, the internet just stops. All lights on the router remain Green, but no device can access the web. A restart fixes it every time, but the cycle repeats.
ONT Model: ZTE F670L [2020 manufacturing ], Firmware Version: V1.1.20P11N1B
Findings from the Logs: I’ve been checking the router logs to see what’s happening, and I found some very specific errors that repeat thousands of times:

Findings from the Logs: I’ve been checking the router logs to see what’s happening, and I found some very specific errors that repeat thousands of times:
- Watchdog Errors :[Informational] user regist watchdog: Monitor open device error No such device or address This occurs every 15 seconds. It looks like the internal system is failing to poll its own hardware.
- VOIP Critical Loop :[Critical] VIP_VOIP: Set VoIP Protocol SIP This error is flooding the logs. I don't use a landline, but the router seems stuck in a loop trying to configure the VOIP service.
- DHCP Lease Failure (3600s Lease):The WAN lease is set to exactly 3600 seconds (1 hour). Right when the internet drops, I see these events in the log:
- rcv EV_T1_EXPIRED on BOUND
- rcv EV_SEND_TIME_OUT on RENEWING
- rcv EV_T_EXPIRED on REBOUNDING
Questions for the experts:
- Is this a known firmware bug with the ZTE F670L on Netplus?
- How to get admin access.
- Is there any way to increase the WAN lease time? My router is heavily restricted and I only have basic 'user' access, not 'admin' access, so I can't see many settings.
