PCMCIA UMTS Card - Network speed Problem

[Reinhard Sy]

Hi

if I insert my merlin U630 UMTS-Card from vodafone into the PCMCIA-Slot
I see the following in /var/log/messages.

Mar 31 08:54:06 localhost cardmgr[3214]: socket 0: Serial or Modem
Mar 31 08:54:06 localhost kernel: ttyS1 at I/O 0x2f8 (irq = 10) is a
16550A


That looks fine.

Then I use:

minicom to set the PIN which works fine. ( the blue light is blinking/
UMTS)

now I start a connection with:

% ifup umts

and all is fine the connection is established:

ppp0      Protokoll:Punkt-zu-Punkt Verbindung
          inet Adresse:10.XXX.XXX.XXX  P-z-P:10.64.64.64
Maske:255.255.255.255
          UP PUNKTZUPUNKT RUNNING NOARP MULTICAST  MTU:1400  Metric:1
          RX packets:8 errors:0 dropped:0 overruns:0 frame:0
          TX packets:9 errors:0 dropped:0 overruns:0 carrier:0
          Kollisionen:0 Sendewarteschlangenlänge:3
          RX bytes:110 (110.0 b)  TX bytes:182 (182.0 b)


routing looks like this:

~ $ netstat -r
Kernel IP Routentabelle
Ziel            Router          Genmask         Flags   MSS Fenster irtt
Iface
10.64.64.64     *               255.255.255.255 UH        0 0          0
ppp0
default         10.64.64.64     0.0.0.0         UG        0 0          0
ppp0


But I am very unhappy with the flow rate I got only a max of 8Kb/s.

How I can improve this ?

If I use the same card on the laptop (dell C800) with W2K then I got
345kb/s.

Here my /etc/sysconfig/network-scripts/ifcfg-umts file:
ONBOOT=no
USERCTL=yes
PEERDNS=yes
TYPE=Modem
DEVICE=ppp0
BOOTPROTO=dialup
AC=off
BSDCOMP=off
VJCCOMP=off
CCP=off
PC=off
VJ=off
LINESPEED=460800
MODEMPORT=/dev/ttyS1
PROVIDER=umts
DEFROUTE=yes
PERSIST=no
PAPNAME=VFD2
WVDIALSECT=umts
MODEMNAME=ModemUMTS
DEMAND=no
IPV6INIT=no
PPPOPTIONS=

MTU=1400



Any hint would be great

Thanks
