Archer NX500 V1 random modem crash/reboot
Archer NX500 randomly crashes and reboots. This has happened 3 times in the past few days after weeks of stable operation.
What happens:
- The modem completely drops (shows "No SIM Card" or "Disconnected")
- The router reboots itself automatically and regains connection after a few minutes
- No manual intervention needed, but internet is down during this time
- No warning, no pattern — happens randomly
What I've tried:
- Created custom APN profile with IPv4 only (instead of IPv4 & IPv6)
- Network mode set to 4G/3G
- Carrier: Tre (Sweden), APN: bredband.tre.se
Log evidence: The system log shows nothing before the crash (wiped by reboot). After reboot I see: LTE: first_conn_uptime=76 This confirms a full system reboot occurred.
Similar to the NX600 issue reported here: https://community.tp-link.com/en/home/forum/topic/841778
The difference is that my router reboots and recovers on its own, whereas in that thread the router stayed in a failed state until manually restarted. A beta firmware helped that user. Is there a beta firmware available for the NX500 V1 that addresses this modem crash issue?
Hi, thank you very much for the feedback.
I'd like to follow up on your case via email and forward it to the senior engineer for further assistance.
Can you update the email with some screenshots of the internet status, such as:
(It would be better to save the "Internet status" after the modem crashed, but if it is working properly now, you can save a screenshot of this page as well. Thank you in advance!)
