I have wAP ac LTE6 Kit (RBwAPGR-5HacD2HnD&R11e-LTE6), a few years old, but almost never used.
Other day I updated RouterOS to latest stable 7.18.2 and latest LTE interface firmware (don’t remember version).
I reseted configuration to default, and poped in a A1 Croatia ISP SIM card.
Everything was working great, LTE signal is OK, WiFi is working OK.
But after a few hours of operation, about 10 hours, internet is not working.
After power reset everything works OK again.
This morning after another internet fail I connected to MikroTik with my phone, and saw logs flodded with messages every few seconds that LTE interface is resetting.
Did anyone had similar problem, do You think this is RouterOS / configuration problem, or hardware problem ?
Hi, I can´t help much, all I can say is what I would try is downgrading by using netinstall to around 7.15.3 or even to a lower version. I got one too and that is stable on an older ROS7 SW since last summer and it was also performing well on ROS6 before that. Unfortunately I can´t check right now which ROS is that on, I´m on that site only occasionaly,
It is my main router with lots of firewall rules/DHCP/DNS/NTP for that site.
I will dowgrade RouterOS and test it later today, but I am afraid that problem is in latest LTE modem R11e-LTE6 firmware v038.
How to get older versions of firmware for R11e-LTE6, to try to downgrade ?
I googled and found that You can get latest firmware V038 using this link:
https://upgrade.mikrotik.com/firmware/R11e-LTE6/image
But I want to get V034, how to get that ?
Hello there, I have seen it before in an Ltap LTE6 kit.
Can you please send the logs and your config to take a closer look
Sorry I don´t know, but you could try to install a testing version:
/interface lte firmware-upgrade lte1 upgrade=yes update-channel=testing
Maybe you should open a ticket with MT, but I would not have too high hopes.
I rasied a support ticket with MikroTik, awaiting their response.
As suggested by the woland, over the weekend I downgraded RouterOS to v7.15.3 and for 55 hours there was no issuses, 0 links down on LTE interface, so i think there is issue with the wAP ac LTE6 Kit and RouterOS v7.18.2.
Thank you! I thought it was just me. Same problem with my LHG-LTE6. Also using a R11e-LTE6. I also have a support ticket open. A fix is already in the works. Check the 7.19 beta announcement thread.
Hello, same issue with hAP ax lite LTE6 and 7.18.2. I tried 7.19rc1 no more luck…
The only thing to do is to reboot or power-reset the routerboard…
I just opened a ticket.
The logs :
lte,error lte1: no response for: AT+GTANTINFO?
interface,info lte1 link down
lte,info lte1 mbim: error: expired transaction #28
interface,info lte1 link up
interface,info lte1 detect UNKNOWN
lte,error lte1: no response for: AT+CEREG=2
interface,info lte1 link down
lte,error lte1: no response for: AT E0 V1
lte,error lte1: no response for: AT E0 V1
lte,error lte1: no response for: AT E0 V1
lte,error lte1: no response for: AT E0 V1
The same issue…
RBM11G + R11e-LTE6 (7.19.1 and V038 ).
The only reboot or power-reset solves an issue
