Has anyone connected to 3g/umts/hsdpa?


Hi,
I have a Sierra Aircard 860 that connects using linux but only gets 10kbps up while it gets about 40kbps up on Windows. It seems like it is connecting to the GPRS network but not the 3G HSDPA network under Linux.

Anyone else trying to make this work?

Thank you.

Well, I've got the same problem on my Fedora Core 6, using Motorola RAZR V3x with bluetooth.

On Windows (using UMTS) I can reach 40Kb/sec, on Linux I get only 10Kb/sec.
This is a very annoying problem, have you solved this puzzle?
Please help us understanding.

Slow Aircard connection

I wrote a howto draft, you can find it here:
http://www.murga-linux.com/puppy/viewtopic.php?t=7648

I think this is the piece you are looking for:

edit /etc/ppp/ip-up
#Add this line to increase modem speed
#Without this I only got 10kbps up and 37kbps down
#With this I've gotten almost 400k down (so far) but seem to be
# capped at 57kbps up
setserial -a /dev/modem spd_vhi

Of course you will need to adapt this to your specific installation.

Thanks very much but it doesn't works for me
I'm using bluetooth to connect to UMTS (using /dev/rfcomm0)
if I
setserial -a /dev/rfcomm0 spd_vhi

I've got this error.
"Cannot get serial info: Invalid argument"

Have you got an idea on how to fix this problem?
Please help and thanks for your reply.
