Hi,
I have a TRB500 with the latest main FW (TRB500_R_00.07.15.2).
The modem firmware is shown as RG501QEUAAR12A10M4G_04.200.04.200. Not sure if this is old or not.
In the web UI it is displayed that I can only update the modem firmware via a file. Where do I get the latest version?
I have quite a lot of connection issues even though the signal strength is reported to be fairly good. Provider is A1 (Austria).
Thanks a lot in advance.
Good afternoon,
In the first instance, I would recommend seeing if all of the antennas are correctly screwed on the device. Please clarify whether you use Teltonika original antennas, or third party? Also, I would want you to put the device in the most optimal conditions, at least for testing purposes. Minimal physical, and network band obstructions. Clear space.
Please also try to band-lock the device. Check which band the device connects to the easiest, and in WEBUI Network → Mobile → Connection change the band to manually connect to your preffered one. More info : Band Lock - Teltonika Networks Wiki
I would also like for you to change your APN from auto, to custom. I would either need to know what mobile provider you use, or you can simply find out, what apn your mobile provider uses, and manually type it in in WEBUI. Instructions : Auto APN - Teltonika Networks Wiki
Please also try to factory reset the device. Remember to save a backup file if you need your configuration to be saved : TRB500 Maintenance - Teltonika Networks Wiki. However I would like you to test without configuring it after a reset.
Please advise if after going through the information above, you are still unable to achieve your desired result. Please also advise what that expected and desired result is. Are you able to achieve same speeds in a phone, or another router?
Regards,
Arturas
Hi,
yes, I’m using the original antennas and they’re screwed in properly. The device is located at a spot in the house where the mobile signal is fairly good.
The failure condition is resulting in a complete loss of internet connection for a couple of minutes and also a significant drop of the bandwidth from time to time. Usually after a complete device reboot everything works perfectly fine again for a few hours.
I changed the settings to use a manually provided APN from the provider’s website.
I also enabled the band locking to the bands, which were automatically chosen after a device reboot. These are B3 for LTE and N78 for 5G. For UMTS I selected all of them but these aren’t used anyway as far as I can tell.
See the attached screenshot for the used bands and the signal quality.
I’ll have the changed settings applied for 1-2 days now and get back to you with an update…
Hi there,
That is okay. Please monitor the device after made changes and lets us know if you don’t get an improvement.
Regards,
Arturas
