Hi,

I choose to only test download speeds for now but upload will also be of
interest later on.

I had actually tried to change the N_IN_URB/N_OUT_URB before sending of the
report but now I've been testing with both 8 and 128 but the speed remains the
same. Download speed max 1.0Mbit/s in Linux while the Windows driver could get
an average of 2.5Mbit/s at my current location (different location than during
the last test).

I have also tried the new 1.6.0 driver as kindly supplied by Sierra but the
speed remained the same 1.0Mbit/s with the new driver as well...

Anything else you think I could try?

Then this is not an issue on the kernel side, you might look higher up.
I have had reports of people incorrectly calculating network speeds
compared to Windows due to other tools running at the time, or
misconfigured networks.

As for how to look into this, sorry, I really don't know.

good luck,

greg k-h
