IPV6 not supporting Sierra Wireless WP7611

Hello Sierra Team,

It is observed that IPv6 is not supporting on WP7611.
When our network provider disabled the IPV4 in region, our devices stopped data session and ping response is network not reachable.
~ # ping
connect: Network is unreachable

We tried to enable IPV6 via AT!CUSTOM command, but problem remain same i.e. no access to data.
~ # lte_gps_sample_app ‘at!custom=“IPV6ENABLE”,1’


Kindly suggest other methods to enable IPV6. Currently production is on hold.

Have you contacted distributor?
What did you set for at+cgdcont?
Other user can get ipv6 in +cgpaddr


Please check below response.
~ # lte_gps_sample_app ‘at+cgdcont?’

+CGDCONT: 1,“IPV4V6”,“jionet”,“”,0,0,0,0

~ # lte_gps_sample_app ‘at+CGPADDR’



Further please refer to the attached logs for better understanding of the issue.

Didn’t it have both ipv4 and ipv6 addresses?

How about pinging google IPV6 dns server?

Hi, Please check the attached logs, i was able to ping6 with google IPV6 address. But this is only working while selecting option IPV4V6 option.
If i make a APN profile with selecting IPV6 only, ping is not working. Please help to understand the issue.

you can have a look on here:

what is the actual problem on using IPV4V6?
from your +cgpaddr, I can see both IPv4 and IPV6 addresses.

Cellular network provider stopped the IPV4 in our area and enabled IPV6( Upgraded in all region).
After this modification on network our devices stopped data session.
On our request network provider enable both (IPV4 & IPV6).
Our concern is any change done by network provider should not affect our devices. So we want to make sure that device should be working with both IPV6 and IPV4 individually. Can you help to understand more on IPV6 testing with WP7611 devices.

Isn’t it working fine here?
