I am hoping someone can help me with a problem I am having.
I have a SXT LTE6 kit-US. When I first got it I inserted my T-Mobile SIM card in it and did a Quick Set, and all was good. It connected to the T-Mobile network just fine and I had internet connectivity.
I then did an Auto Upgrade, which installed v7.6. All good after that. I then did a RouterBOARD firmware upgrade to the v7.6 Again, all was good.
I then went into the lte1 interface and did the “Upgrade Firmware”, and that is when I ‘lost’ internet connectivity.
The problem I see is that it is no longer getting an IP from the carrier. I do not believe this is a SIM card issue as I tried another SIM card I have and the same problem exists.
I believe it has something to do with when I did the firmware upgrade through the lte1 interface.
So far I have done a factory reset, and even have done a Netinstall with no change. I am at a loss.
I have another SXT LTE6 kit coming, so I can verify that the SIM is not the issue.
Is there a way to roll back the firmware upgrade that was done through the lte1 interface?
I’ll check and see what the firmware is on the new one coming in.
Just an FYI, I am really unfamiliar with the forum, support, and such. I usually just google things to find my way around the Mikrotik equipment I have. This one has me stumped though. It is my first time using Mikrotik for an LTE modem though, so it’s all new for me.
Just as a visual reference,
Before the firmware upgrade, there was an IP address in the Internet field, and the same one in the VPN field. Now they are just 0’s.
In most cases issue is solved by downgrading to the previous working ROS firmware.
Then upgrade the LTE modem.
Then upgrade again to the latest ROS firmware
LTE is working since all signal parameters are being shown (quite good too, I must say …)
Are you sure APN settings are correct ?
Go to interfaces, LTE, then the button with APN.
You can also enable LTE logging and check the log.
/system logging add topics=lte
PS after using Quickset the very first time, don’t use it anymore !
Quickset is only for setting up basic stuff starting from a default config. Once things have changed, it’s hit or miss when you use it again.
Wouldn’t doing a hard reset using the reset button downgrade to the previous working ROS firmware?
The reason I ask is I just did another hard reset and it does show the 7.3.1 as the factory and current firmware(with the option to upgrade to 7.6 below it).
When I go in and look at the LTE firmware, it is the same as before.
Do I need to do a Netinstall of the 7.3.1 to change it all back?
Sorry if this is confusing, I do not mean to make it so.
I did a factory reset(hold the button, apply power, and wait till the light goes off).
After doing that, it still has ROS v7.6 as the package(it shows v7.6 on the top bar), but when I go in and look at the RouterBOARD window it shows “Current Firmware” as 7.3.1 with the option of “Upgrade Firmware” to 7.6.
Oh, sweet, they changed those commands versus help pages…
Go to winbox
Interfaces
Lte
Check firmware.
As for routerboard firmware upgrade, it can be done (at some point in time it is needed anyhow so better do it already). But it will have no impact on this problem.
New problem, I did a “Reset configuration” on the Quickset menu. Router rebooted, and now it will not accept a default password for a login. Just get “wrong username or password”.
I ran into this once before early on and had to do the Netinstall in order for it to allow me in.
I literally have never had this much trouble with any other Mikrotik device ever.
Some strange but interesting progress has been made.
I was looking around on the web for a solution, came across some old script for setting up a SXT LTE.
When I go in and change the APN authentication to CHAP or PAP(anything but none), and add a username, then all of a sudden I get an IP address pushed to me.
No internet from it, but something is giving me an IP because of it.
