Flint wifi 2.4 Ghz not working

Hi, Strenge issue here for the last few days.
The 2.4 GHz wireless is not working anymore.
I try to explain, I have 5Ghz and 2.4Ghz wireless networks with different names, and a few days ago the 2.4Ghz was not visible, and even if I try to connect to it as a “hidden” network, it seems that it does not exist.
I checked in the control pannel and is seems that everything is in order, I also checked in LUCI, same thing.
I rebooted the network, the router, and I also updated to the newest available firmware.
Still the same issue.
Can someone suggest me some other test, or command to check what it going on, and in case, I can I solve the issue.
This evening I will try to reset completely the router.

Just reset my flint using GUI, and still the 2.4Ghz network not present.

There is a way to restore the router in command line that will be more deeply?

Please let me know.

Could you please try this method the flash the firmware v4.4.6?


If still this issue, please take a request here for the warranty.

Thank you.

Hi @rain ,
Thanks a million, after the flash with uboot method, the 2.4Ghr network works again.
the router is now back in place, and I will let you know in case of any other issues.


Thank you for the kindly updates as well.
Have a nice day.

I have the same issue, running 4.4.6.

2.4Ghz wifi just stopped working.

I am going to try the reset via uboot, and report back.

It would be interesting to know why the problem occurs.

Is it a problem caused by upgrading firmware via web gui?

Should future firmware updates be avoided via the webgui?

EDIT: Followed steps advised for ethernet uboot firmware flash, and now 2.4g internet works. Bit of a pain to re-setup all the applications and samba fileshare users, but glad it’s fixed.
