Flint 2 wont recognize cabel connection

Technical Support for Routers
1

Hello everyone, I'm stuck and hope to find a solution to my problem here!
My Flint 2 ran with firmware 4.6.2. without any problems, now I have the problem that the devices connected by cable are no longer recognized. The devices and cables work perfectly on another router. The Flint no longer recognizes the devices.
Wifi works.
No changes have been made, the router has been running smoothly since February.
I have already done a reset without success. Went to factory settings, without success.
As vpn I used vyprvpn until now without problems, since the reset this also no longer works.
Fiber optic -router AVM Fritzbox-Flint 2.
I hope that all the important points are there and hope for a solution.
Many thanks in advance.

Hi Paul,

please reboot the router, plug out and plugin the cable to your Fritz!Box again and upload/post the logs then.

Does the Fritz!Box still detect the cable?

still the same problem. the computers connected via lan are not recognized.
Wlan works, the connection to fritzbox works.

Could you please describe a bit more what the issue is about?
The log tells us, that the cable connection itself seems to work and link is given.

The GL gots the IP 192.168.178.39

5

Ok, I've checked everything again. I have 2 devices connected to my Flint via wifi, everything is ok and there are 2 devices, a computer and a Raspberry connected via lan, this device connection no longer works.
I have tried the cables and devices on my fritzbox, everything works fine there.
the Raspberry shows the following -ethO:Link is down.
I hope it is more understandable now.

6

Did you try all LAN ports of the Flint?

7

Yes, I have just reconnected, no connection to the 2 devices on lan 2-3-4-5. I have also just tried the WAN/LAN 1, here it recognizes a connection, but it does not connect the 2 devices.

8

Could you please try to reset the router using the Uboot method?

Firmware is here: GL.iNet download center

9

OK I'll do my best but it will take some time.

10

Hello, it took a while. I have tried everything but without success, I can't connect to Uboot. I have tried 2 different laptops, browser Firefox, chrome and edge, tried every connection always with the same result, no connection timeout. I have searched the internert but have not found anything really helpful. Any idea?

11

Did you set the correct static IP like described in the article?

12

Yes, 192.168.1.2 and Use browser to visit http://192.168.1.1, this is the Uboot Web UI.

13

May I know if the Flint 2 downgrade the firmware to 4.6.2, would the LAN ports work?

14

Hello everyone, I have tried a few things over the last few days, unfortunately without success. Since I could not establish a connection via Uboot, I first updated to 4.6.4 via the local update, then back to 4.6.2, then to 4.5.8 and finally even to 4.5.4. Unfortunately, the result is always the same. I am now back on 4.6.4
Eth0 link is down, wifi works, internet works, only the devices connected to the flint 2 via lan are not recognized.
Could it be a hardware problem?

Hi may I know how about now? The screenshot you post shows the Eth1 and Eth2 work ok in the v4.6.4
