Zoom USB external modem install failure

English Network/Internet

Hi,

OpenSUSE 11.1; kernel 2.6.31.12-0.2-default

Tried to configure via:
Zoom CD driver: 1.06_k2.6.22.17_01_default-1suse.i586.rpm
linuxant driver: dgcmodem-1.13_k2.6.31.5_0.1_pae-1suse.i586.rpm

Used Yast2 & ,also, command line rpm i …, in su mode

Doesn’t create /dev/ttyACM0 nor any /dev/ttyx

Output of dgcconfig

SuSe:~ # dgcconfig
Conexant DGC USB modem driver, version 1.06

If you need assistance or more information, please go to:
Linuxant - Company information

When reporting a problem for the first time, please send
us the file generated by “dgcconfig --dumpdiag”.

No pre-built modules for: SuSE-11.2 linux-2.6.31.12-0.2-default i686-SMP

Please obtain the appropriate variant of this package for your system
or try the generic RPM or tar version.

I did try generic with same result.

My apologies
The OS is SuSE-11.2 linux-2.6.31.12-0.2-default i686-SMP

Upgraded to SuSe 11.3

Didn’t load any USB modem driver

wvdial and Kinternet/KDE3 now dial and connect

Neither Firefox nor Konquerer connect to Internet

Same happens whether wireless router is on or off

Any ideas how to resolve browser connect issue?

Is Network Manager enabled concurrently? That can prevent a DNS being available when dialling out.

cat /etc/resolv.conf

We may as check the route table (for gateway) as well

/sbin/route -n/CODE

Hi deano_ferrari,

Below are the results from commands I ran from su, and from kInternet log. I connected with dialup with an DNS error message. Network manager process was killed. I connected via dialup with network manager running but with wlan0 disabled, but browser wouldn’t connect to Internet.

I will try loading a dgcmodem driver.

What do the ? mean in wvdial output?

Thanks for your help.

These commands are with networkmanager running.

/etc/resolv.conf file autogenerated by netconfig!

Before you change this file manually, consider to define the

static DNS configuration using the following variables in the

/etc/sysconfig/network/config file:

NETCONFIG_DNS_STATIC_SEARCHLIST

NETCONFIG_DNS_STATIC_SERVERS

NETCONFIG_DNS_FORWARDER

or disable DNS configuration updates via netconfig by setting:

NETCONFIG_DNS_POLICY=’’

See also the netconfig(8) manual page and other documentation.

Note: Manual change of this file disables netconfig too, but

may get lost when this file contains comments or empty lines

only, the netconfig settings are same with settings in this

file and in case of a “netconfig update -f” call.

Please remove (at least) this line when you modify the file!

If I undertsnad your results correctly, wvdial works ok as root. Ok, maybe you need to add yourself to the ‘dialout’ group first via YaST > Security and Users…

Also, what does this return (when device plugged in)?

ls -l /dev/ttyACM*

You’re close…

7

BTW, when dialled out, then /etc/resolv.conf should have the namservers reported by wvdial

pppd[0]: primary DNS address 66.81.1.250
pppd[0]: secondary DNS address 66.81.1.252

If you don’t, that is definitely the problem. Network Manager should NOT be running (and should be disabled in YaST > Network Devices), otherwise the dialler won’t be able to add the nameservers to /etc/resolv.conf).

A similar issue here.

Hi deano_ferrari,

I am replying to your thread via dial up, thanks to your help.

Disabling network manager from YaST>Network Devices>Network Settings was the solution. What I did was to select ifup option from the General Tab. Previously, I only disable NM from the task bar NM icon.

Summary for others reading this thread:

SuSe 11.3 loads its own driver for USB modems. You do not need to install any dcgmodem rpm. I use Kinternet to make a connection after I use the ifup option as per above to stop Network Manager.

SuSE team should consider code to have SuSe to auto transfer browser to dialup if wired and wireless ethernet are not enable via NM at the task bar icon.

I am embarrassed that I didn’t think to stop NM through YaST.

I, only, need to use dial up when I am in upper Maine.

Thanks for your help.

Bob

Glad to read its sorted!
