Can not ssh to FX30 even after flash a stable version of the firmware

Hi,

my device : Model FX30 generic Lte S/N VU911670630810

We were using the FX30S as a serial modem. We would want to use the FX30 as a modem through the RJ45 connector and not through the serial connection.

-Does the FX30 handle PPPoE protocol ?

During my testing I change the static eth0 IP using the web interface at 192.168.2.2 to one within my range and I have been able to connect the FX30 through ssh using this new static IP.

In order to quickly configure my Sim I used cm command. Once my sim was configured the last command I used was cm data connect. After that I power off the FX30 and I have never been able to connect through ssh again within Ethernet (at the static IP) neither USB (at 192.168.2.2).

PING 192.168.2.2 (192.168.2.2) 56(84) bytes of data.

I tried to add an IP to usb0 : ip a add 192.168.2.3 dev usb0

and even « ip link set usb0 up » but no more luck on the ping

Then I thought I maybe did something wrong so I reset the FX30 (I enable the reset from the AT command) without more success. Finally I download and flash the following firmware

FX30_WP77xx_full_R11.0.0.007-generic_gcf-SWI9X06Y_02.22.12.00.cwe

./swiflash -m wp77xx -i ./FX30_WP77xx_full_R11.0.0.007-generic_gcf-SWI9X06Y_02.22.12.00.cwe

Everything looks fine but I still have no ping at 192.168.2.2

- Anything that I didn’t try to get back a ssh connection ?

I am still able to send AT command using minicom through ttyUSB2

Thanks for your time and help,

Simon

Hi SimonC,

FX30 doesn’t support PPPoE

192.168.2.2 is the default IP for interface usb0. This is used for direct physical connection between the FX30 and the host LAPTOP. Please don’t change this IP for usb0.

In order to troubleshoot the issue easily, please provide the IP that you assign to eth0 and the results of commands below:

Hi Jerdung,

Thank you for your answer.

FX30 doesn’t support PPPoE. Ok thanks you save me time on this then

The static IP was 192.168.13.31 I changed it for : 195.83.22.165 using the web interface at 192.168.2.2 But I am not sure which one is configured now after the hard reset and the flash

Hi,

Everything fine. It was my sys admin who prevents me from opening a new ssh. Sorry for that at least i learn about the pppoe.

Thanks for your help,

Simon
