    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=
    IDLETIMEOUT=600
    MTU=1400

    Any hint would be great

    Thanks
    Reinhard
