Flint 2 no wifi or wired connection

Routers
1

Hi guys.
About a day ago I bought Flint 2 from Amazon Germany.
Router came and I set it up manually.

Only settings I did was to clone mac adress from my old router, setup Dhcp reservations for all my clients ( about 25 in total), updated the firmware as it was popping up in system.
After approximately 15 hours of work I came back home today to find the router not broadcasting wifi sygnal and not accessible wia wired.

Of course no any internet at all. Solid blue LED illuminated. Took power off and back on but that didn't help at all.
Then I took all cables and installed my old router and it worked as a charm.

Hooked the flint2 to my laptop and was able to reach admin panel and all my settings were there.
Thought might be some kind of glitch so I hooked it up back to my network but it didn't work as before...

Tried hard resset via the button and power cable but didn't work it doesn't broadcast wifi and admin panel not reacheble on 192.168.8.1...
Solid blue LED stays on even when nothing plugged at the back

Could you please advice what to do?

I’d say it would be good if you could go through the syslog and see if there are any errors. Otherwise probably can post your log file so the others can give you a better advice. Cheers!

Hi

If the LED on the Flint 2 is stuck on a solid blue color, it may be because the router has got stuck in the boot process or has been bricked, due to some unknown reason.
Please refer to What should I do if my router is bricked - GL.iNet Router Docs 4 to unbrick it.

Please note that you need to connect your PC to LAN 2, 3 or 4 to access uboot.
WAN and LAN 1 will not work with uboot.

If you are unfamiliar with these procedures, please contact [email protected] for after-sales support.

Many thanks for your replies.

Last night I've managed through uboot to flash 4.8.2 which finaly booted to admin menu and allowed me to do changes via the menu. Surprisingly all is working untill I take power off ( taking power cable off). Once I put power on it gets back to solid-blue-led state and once again no wifi and no access to admin panel via wired.

Also I tried 4.8.3 and 4.7.7 firmwares and it wasn't booting at all even the first time…

This seems a bit unusual.

Please reflash the 4.8.2 firmware via U-Boot, then SSH into the router and run the following command:

df -h

After that, please share the command output with us.

If possible, please keep the router powered on and connect it to GoodCloud, then share it with us following this tutorial.
We’d like to remotely inspect the device to better understand the issue.

Just to let you know I've managed to find the fault.

The external power supply is gone...

After router went completely off ( no lights, no signs of life) I measured with multimeter the power supply output and it was showing 7.8v....

It is clear now why router bricks as the power supply not providing enough power.

With a similar specs power supply, the router now opprates as intended and every single time when I remove and plug back in the power cable.
