Howdy,
just got my Chateau LTE12 and it came with latest beta preinstalled v7.0beta6. Seems like this release is not in public channels yet, it’s OK but, I have just configured it to use with Telia LT fixed IP APN, and I’am still getting dynamic IP. It works as expected with same SIM and APN config on Huawei router. May be there some known issues with beta release? Should I downgrade to stable instead? Which debug information should I provide?
Thx.
Please read a documentation, general about lte: https://wiki.mikrotik.com/wiki/Manual:Interface/LTE
Please activate log-s:
/system logging add topics=lte
In logs try search what APN is used in reality… I know that APN can be not used, or used after usb power-reset, or just works only 1x after reboot… some strange behaviors with APN at ros7b6.
I not have Chateau then cannot test the ros7b6, at public7b5 I have more problems and just wait for new betas.
Sounds a bit strange that it was shipped with beta software. Sure it hasn’t been used before?
Chateau is with ROS7 only, the official release is ROS7beta5 but at Chateau is ROS7beta6.
MikroTik never publish release candidate or stable ros7 and all person who buy Chateau receive ros7b6.
Thanks for the reply. After digging through logs I see this:
08:12:54 lte,debug lte1 mbim: lte status: attached apn: omnitel
08:12:54 lte,debug lte1 mbim: apn: omnitel user: omni
seems like You right, and LTE apn is ignored, so then default is taken from BS?
probably.
you can try few actions to check they behhavior
maybe apn is used after one of that action and you can found some schema to fix it.
I had the same problem. Turns out there is an option for the APN profile “use-network-apn”, which is only accessible via CLI and default yes.
Enabled, it ignores your APN settings and uses the APN provided by the network. Set this to no and it starts using your configured APN.
True, I just have access to one of Chateau and grab all possibility options.
[admin@MikroTik] > interface/lte apn/set
add-default-route ipv6-interface passthrough-subnet-selection
apn name password
authentication numbers use-network-apn
default-route-distance passthrough-interface use-peer-dns
ip-type passthrough-mac user
[admin@MikroTik] > interface/lte apn/set use-network-apn=
no yes
[admin@MikroTik] > interface/lte apn/set passthrough-subnet-selection=
auto p2p
[admin@MikroTik] > interface/lte apn/set ip-type=ipv
ipv4 ipv4-ipv6 ipv6
This solves the issue. Thx SIB
