Just recently I bought the R11e-LTE6 kit. Before that I used Tplink Archer router but I wanted better bandwidth in my house.
In short, the device establishes LTE connection and I use winbox to open the device’s terminal and can ping internet address such as 8.8.8.8. Few successful replies and then the ping command says timeout and I can’t reach Internet anymore.
If I reboot the router same thing repeats again: lte connection gets established, ping is working and few seconds later transitions to timeout, while the whole LTE interfaces says Full functionality, has ISP provided IP address and no session drop is registered.
I am using default configuration, the device itself is plugged into local, dumb switch and all testing is done with valid SIM card with sufficient resources. I also called my ISP to confirm that the router is connected so that I can be sure that their side is cooperating as expected.
Few days later I upgraded to latest Rotuer OS and LTE modem firmware versions.
I need help in troubleshooting to come to the source of the problem. Shouldn’t the rotuer be able to work just out of the box like most other consumer products? Am I missing something obvious as I am not accustom to the Mikrotik products? Help, please!
It came to my attention that there could be a problem with a LAN cable. 10m of LAN cable was used to connect POE with the device which could be a problem for the device when it is power hungry. I used ubiquity Noanostations devices on 50m+ UTP cables and all were PoE powered and there was no issue with that so I didn’t think that this could be a problem.
I brought the router down from the roof and connected it on shorter cable. It works stable for now and I will update how it goes. If it works ok then it could be that the stock provided power adapter/PoE is just too weak for the task. Will see…
[admin@MikroTik] > ip route print
Flags: X - disabled, A - active, D - dynamic, C - connect, S - static, r - rip, b - bgp, o - ospf, m - mme, B - blackhole, U - unreachable, P - prohibit
It shows that the session is up (session-uptime: 33m25s), but still no ping getting out on the internet:
[admin@MikroTik] > ping 8.8.8.8
SEQ HOST SIZE TTL TIME STATUS
0 8.8.8.8 timeout
1 8.8.8.8 timeout
…
If I disable and enable LTE interface to get it to reconnect freshly, ping starts working ok but fails within a minutes.
The following commands were executed in sequence just to demonstrate how it fails suddenly without touching any other options on the router. Just working in its terminal window:
If I ruin torch on lte1 interface while running ping it appears as if something is flowing to lte1 but not coming back? (I don’t understand the tool yet):
[admin@MikroTik] > /tool torch
interface: lte1
