Recently received and setup my RM520N-GL in the mcuzone enclosure, currently using T-Mobile service and have the following configuration:
Firmware: RM520NGLAAR03A03M4G
AT+QCFG="data_interface",0,0
AT+QETH="eth_driver","r8125",1
AT+QCFG="pcie/mode",1
AT+QCFG="usbnet",1
AT+CGDCONT=1,"IPV4V6","fast.t-mobile.com"
I also for NR5G into SA mode only via:
AT+QNWPREFCFG="nr5g_disable_mode",2
Everything seems fine, getting great signal, but in any carrier aggregation configuration I am getting intermittent split second dropouts that cause packet corruption for data being downloaded.
For example, I can aggregate bands n41 and n25 and things appear normal until I start a download for example of a windows 10 ISO via wget, then I get the following errors
2024-07-31 15:12:54 (66.9 MB/s) - Read error at byte 276905974/6140975104 (error:0A000119:SSL routines::decryption failed or bad record mac; error:0A000139:SSL routines::record layer failure). Retrying.
If I lock to a single band, such as n41. Things are normal and there is no packet loss. I am curious if anyone has any insights/thoughts that can lead to a solution.
