OTD140 strange behavior

Hi to all,
We have a strange behavior on an antenna model OTD140, updated to the latest firmware version OTD140_R_00.07.07.1. The upload and download speeds are very low and often asymmetric, like 15 Mb/s download and 26 Mb/s upload. Another strange thing is that the same SIM, an LTE Primary SIM, when placed in an iPhone SE2020 (so only 4G), the upload and download performance is three times better, i.e., 70 Mb/s in upload and download.

Any idea or suggestion?

Hi,

It’s possible that the device is damaged or faulty. Additionally, it has internal antennas that could be detached (Device disassembly will be needed to check that). Please take a screenshot of Status → Network → Mobile to check your signal reading.

Hi,
Just to point out we have this behavior on two devices, same model and same firmware.

Hi,

Did the slow internet speed start after the firmware upgrade, or was it also noticeable with the previous firmware?

Hi,

the slow speed, particularly the asymmetry between upload and download, is present in both firmware versions.
