Only the first LED is on by the time I rushed to the router when it reboots, the rest is off.

Never tried using wired cable at that time, I'm guessing no internet access as it reboots itself?

No special feature setup, no scheduled reboot.

Nothing is needed to be done to recover the internet connection, as it reboot itself, so all the existing connection to the router is dropped for a couple minutes until it finishes boot. Other devices will reconnect automatically to the wireless network after a couple minutes.

Only 2 devices is connected for most of the time, which is my PC and my android phone via wireless connection.

My Archer AX1500 randomly reboots every couple of days.  I tried scheduling a reboot every night to see if that would help.  It did not help.  It still randomly reboots once a day or once every two days.  I also tried cycling power early in the morning but it still spontaneously rebooted about 12 hours later. 

- Using the AX1500 in Access Point Mode

- Firmware: 1.0.2 Build 20190809 Rel. 28188(5553)

- Hardware: Archer AX1500 v1.0

- When I look at the router I see some green lights flash, then a red one flash, then it returns to operation with three green LEDs.

- Auto Reboot is NOT configured.

- I don't know if the wired connections would work.  When I notice I cannot access my network via WiFi, I look at the AX1500 and the LEDs are doing the boot cycle. There is no time to connect a wire to the AX1500.  My other wired connections that do not use the AX1500 work fine.

- When it is rebooting, I can not access my network and therefore I can not access the Internet.  It works fine until it reboots.  Suddenly I lose the WiFi connection on all our iPhones and laptops.

- I have 2.4GHz disabled.  I have 5GHz enabled with 802.11ax only enabled. No guest network. All other settings are default.

- The WiFi recovers and access to the Internet via my network recovers when the reboot cycle is complete.

- There are normally two Apple iPhone 11 pros connected as well as two Apple MacBook Pro laptop computers.

When will you have a firmware update to fix this problem?

Thanks

I am having the same issue. Latest firmware, set in AP mode. This router is less than 2 weeks old.

You might try putting a fixed IP address on the WAN side of the TP-Link in Access Point mode.  I have discovered that it is renewing the DHCP link every 30 seconds.  I am trying to determine if the rapid DHCP renewal is related to the reboot.

@Paul_S It wouldn't hurt to try. I'll do that.

Sunday I have the following changes on TP-Link: I turned off Smart Connect in Wireless Settings so it doesn’t automatically select 2.4 GHz and 5 GHz connections.
At the suggestion of @Paul_S, I gave a fixed IP address - referring to a TP-Link MAC address - to TP-Link in the modem (ZTE) in front of it.
It hasn't started again since then (though it's not been two days since the change…)
(TP-Link is in Wireless Router Mode)
