Wwan0 has IP address, but cannot ping sixfab.com

Sixfab Connect Sixfab SIM

I have installed my 3G/4G/LTE hat, and sixfab core on a new raspberrian sd card per your instructions. The device gets an IP address for wwan0, but is not able to ping sixfab.com.

ifconfig wwan0 shows the following:

wwan0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 192.168.225.59 netmask 255.255.255.0 broadcast 192.168.225.255

TX packets 45 bytes 4601 (4.4 KiB)

This hat and SD card worked with this raspberry pi before I did this new installation.

Thanks!

Hi Will,

If you activate the remote support setting of your device and share the support key with me, I can help.
Could you please share your remote-support token so that I can check and solve it?

Hi Ensar,

I emailed you the token. Thanks!

Thanks for sharing.

You used more than 100 MB of data this month.
Can you update your ‘Monthly Limit’ to unlimited from SIM details and then try to ping it?

I realized I never posted an update. This was exactly the issue. Thank you!

Hello,

I have this exact issue except I haven’t used any of my 100MB data yet. I just activated my SIM.

When wwan0 comes up what kind of link is this? Where did it get its IP address from? I have other WiFi in my area which wlan0 is connected to.

I have very poor cell coverage where I’m currently located. Can I setup my Samsung Android phone as an access point for the Telit modem? My phone has internet connectivity through my WiFi.

Thanks for any ideas.

I’m experiencing the same issue. Just registered my sim. The device status on Sixfab Connect shows connected while using wlan0, but when wlan0 is disabled, it will have no connection via wwan0.

@Skyman @jasper ,

If you activate the remote support setting of your device and share the support key with me, I can help you quickly. Could you PM me your remote-support token so that I can check and solve it? Thanks.

I am having a similar issue with my connection. I get an IP address on my wwan0 but no connectivity past the gateway.

Same issue here. Repeatable with CORE & ECM and QMI. Using a Telit ME910 on RPi 4B. All settings/tutorial input complete for both cases - it just fails to get an IP that lasts.

  • 100 MB data pool in Canada
  • Connection to Rogers/Telus/Bell
  • Failed in Calgary downtown and Charlottetown PEI (both good signal areas).
  • ‘super’ & no user/pass/pin

I was able to overcome this by manually configuring the network (it seems they may not all support dhcp requests).

Although this worked yesterday, it isn’t working today. It may be that the issue comes from the Telit ME910 defaulting to 2G networks before 3G. While it seems like there is signal for this, 2G is no longer supported in Canada by Sixfab’s carriers (Rogers/Bell/Telus). Further, when I try and change my card defaults I get these notices:

sudo qmicli -d /dev/cdc-wdm0 --nas-set-system-selection-preference=‘lte’
error: couldn’t set operating mode: QMI protocol error (3): ‘Internal’

This is the same with ‘lte|gsm’ but different for ‘umts|lte|gsm’:
error: couldn’t set operating mode: QMI protocol error (25): ‘DeviceUnsupported’
This makes sense that umts (4G) isn’t supported as the card doesn’t include this.

Is there anything we can do to allow for these to be changed so that 3G is the preferred option? The card should support it, default to it, and allow for it to be changed. If this is not the case then the ME910 isn’t really usable anywhere in Canada (and should probably not be listed as having Canadian support).

I’ve gone ahead and picked up the 3/4G cards from Telit and Quectel. Hoping one of these will work consistently - will share my experience when received.
