Model: Archer NX200  
Hardware Version: V1
Firmware Version: 1.6.0 3.0.0 v60a2.0 Build 250529 Rel.55411n

Dear TP-Link Support, @Sunshine    @David-TP 

 

As already communicated via email regarding the following ticket:

🔗 https://community.tp-link.com/en/home/forum/topic/830486

 

I'd like to highlight another major performance issue with the NX200 5G router:

Issue: Delayed Failover from WAN to SIM Data

When the WAN (Fiber) connection is disconnected, the NX200 takes 2–3 minutes to switch over to the SIM (mobile data). This causes a serious disruption to internet-based applications like:

  • Microsoft Teams calls

  • VPN sessions

  • Video conferencing

  • Real-time collaboration tools

All of them time out or disconnect, leading to a poor user experience.

 

Comparison with Archer MR400 (4G Router)

In contrast, the Archer MR400 switches between WAN and SIM seamlessly- often within a few seconds. In many cases, users don’t even notice the switch, as the fallback happens quickly and without disruption.

The issue has been resolved with the beta firmware. Many thanks to your team for the quick investigation and for providing the beta in such a short time, which solved the problem. Truly appreciate the quick turnaround.

 

Looking forward to these fixes(for below topics) being included in the official firmware release soon. Thanks again.

Hi, thank you very much for the update.

I saw you're still troubleshooting with our senior engineer. l left him a note, and it is also recommended to mention the delay to the engineer as well. Maybe these two cases are related, and he could help us check them together.

 

I'll also keep an eye on the community to identify any additional similar feedback.

Thanks a lot and best regards.
