many thanks for your answer and sorry for the late reply.
I want to go through the way of using qmicli (or better later python
equivalent), even if it is the more difficult way.
At the moment I am using 2 different scripts, one for a single
connection mode (without qmimux) and one for dual connection mode (with
qmimux):
Currently limited testing to IPv4.

************************************* 5555
*************************************
When using the single connection script, connection can be built up, I
get an IPv4 address, ping work, and wget throughput is around 20 MBytes/s.
Reaction times on wget actions are good.
When using the dual connection script, first connection can be built up
as well, I get an IPv4 address, ping seems to work and same ping time,
but wget is having big reaction times showing error, throughput almost
nothing.
Perhaps some setting is too low? In your page dl-datagram-max-size is
mentioned. One time in wda-set-data-format.
One time in "ip link set ... mtu ...". In the second one I assume
maximum is 1500. When building up a connection I also get a MTU of 1500.
Or are the three places independant? What values could work?
In wda-set-data-format a value of 1500 or 48000 (= 32*1500)?
In examples I googled, dl-datagram-max-size was set to 32768 (=32*1024)
and 31744 (=32*992).
Perhaps I have to use/shall use 48000 (=32*1500)?
Does this correspond to some value I get from module (qmi command) or
from USB descriptor? Or just from experience?
What if the value is too big?
There is "ep-type=hsusb,ep-iface-number=x" in wda-set-data-format". In
you example it is not used. In another example it was used.
I tried with and without, but does not seem to make a difference.
There is mentioned "For better throughput" on your page: If not done
correctly, could it produce such an error, like I am having?
Can I perhaps see the current value somehow? dmsg/system logs? Or
perhaps a way of reading it back?
Best regards and many thanks,
Martin
