Flint 2 mt6000 reboot every 1 hour

Hello! My Flint 2 mt6000 reboot every 1 hour. When uptime section shows “1 hour” - it loses all connections. All reboots. No additional devices via lan is connected.

Flint 2 (GL-MT6000) repeatedly rebooting every 10–60 minutes on stable firmware

Solved.

Hard Reset and back to 4.7.7

Hi there. I seem to be having an issue with my Flint 2 that is very similar to what you experienced, except it’s more like every 20-60 minutes.

Out of curiosity, what firmware version were you on before you rolled back? Will try rolling back to 4.7.7 too since that worked for you.

Thanks.

I am trying to determine whether my Flint 2 (GL-MT6000) may have a hardware fault.

I installed the router yesterday when my full-fibre connection was activated. Since installation, the router appears to reboot spontaneously every 10–60 minutes.

Observed behaviour

When the issue occurs:

  • The network freezes briefly.

  • The router LEDs cycle as if the device is restarting.

  • Wi-Fi and Ethernet both drop.

  • The admin panel session is lost.

  • Router uptime resets to 0.

During the event, continuous pings to the router also fail.

Example:

ping 192.168.1.1 -t

Reply from 192.168.1.1: bytes=32 time<1ms TTL=64
Reply from 192.168.1.1: bytes=32 time<1ms TTL=64
Request timed out.
Request timed out.
Reply from 192.168.1.1: bytes=32 time<1ms TTL=64

The outage lasts roughly 45–60 seconds, consistent with a reboot cycle.

Firmware history

  • Initially running beta firmware

  • Rolled back to Stable 4.7.7

  • Multiple factory resets performed

  • Issue persists on the stable release

Troubleshooting steps already taken

Factory reset (multiple times)

Wireless configuration simplified:

  • WPA2-PSK only (WPA3 disabled)

  • Fast roaming (802.11r) disabled

  • Smart Connect / band steering disabled

Manual channel configuration:

  • 2.4 GHz → Channel 1, 20 MHz

  • 5 GHz → Channel 36, 80 MHz

Hardware acceleration tested:

  • ON

  • OFF

Issue occurs in both configurations.

Multi-WAN interface status tracking disabled.

Environment

Router: GL-MT6000 (Flint 2)
Firmware: Stable 4.7.7
WAN: PPPoE via FTTP ONT
Clients: mix of wired and wireless devices
Frequency: roughly every 10–60 minutes

The issue affects both wired and wireless connectivity simultaneously.

Log observations

Just before the event I see repeated WPA handshake failures from multiple clients:

WpaEAPOLRetryAction(): 4Way-MSG1 timeout
Send DEAUTH frame
MacTableDeleteEntry()
Recv Assoc from STA
ASSOC Send ASSOC response

Example:

4Way-MSG1 timeout with 48:e1:e9:3b:08:b9
4Way-MSG1 timeout with cc:3b:fb:e3:cc:58
4Way-MSG1 timeout with c4:db:ad:0e:59:37

In earlier logs I also noticed:

warp_probe(): probe fail since warp is full
warp_dev0: probe of 15010000.wed2 failed with error -1
ExtEventBeaconLostHandler(): AP Beacon OFF!!!

Questions

  1. Are spontaneous reboots like this a known issue on the MT7986 platform or the Flint 2 firmware?

  2. Could the warp_probe / WED errors indicate a driver issue?

  3. Given the behaviour on stable firmware and after factory resets, does this point toward a potential hardware fault?

I can provide full log bundles if needed.

Any guidance would be appreciated. Thank you.

4.7.7 work flawlessly. Today update again to 4.8.3. Reboot every 1 hour
