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. From xxx icmp\_seq=1 Destination Port Unreachable From xxx icmp\_seq=2 Destination Port Unreachable From xxx icmp\_seq=3 Destination Port Unreachable 23: **usb0:** \ mtu 1500 qdisc noop state **DOWN** group default qlen 1000 link/ether **c2:df:6a:b7:a5:14** brd **ff:ff:ff:ff:ff:ff** I tried to add an IP to usb0 : ip a add 192.168.2.3 dev usb0 23: **usb0:** \ mtu 1500 qdisc noop state **DOWN** group default qlen 1000 link/ether **c2:df:6a:b7:a5:14** brd **ff:ff:ff:ff:ff:ff** inet **192.168.2.3** /32 scope global usb0 valid\_lft forever preferred\_lft forever 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 Detecting USB of the target DONE Communicating with the target DONE Switching to firmware download mode …DONE Downloading the firmware …DONE Rebooting the module …DONE Firmware Download SUCCESS 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, > [@SimonC](#): > > Does the FX30 handle PPPoE protocol ? 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: ATI ATI8 AT!ENTERCND=“A710” AT+CGDCONT? AT!GSTATUS? AT+COPS? AT!IMPREF? AT!IMAGE? AT!USBCOMP? Thanks, ---

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
