Connect to internet via cellphone problem - KDE 4 (solve)

[eddiemouse]

Good day

Today I had install the new Pclinuxos 2010. I try config linux to use my Sony Ericsson W705 as a modem to connect to the internet. I went to the PCC (PClinuxOS Control Center) choose Network & Internet, then "Set up a new network interface". I had choose the "GPRS/Edge/3G" option. Linux does pickup my phone "ppp0: Sony Ericsson Sony Ericsson W705". When I click next, it gives me an error "Unable to open device /dev/ttyACM"

Can anybody help me

Connects that phone through a USB cable?  Not likely but in case your phone could be seen as a dungle and I tested a few here some time ago (dungles) and the device needed to be /dev/ttyUSB0.
Maybe trying some other settings would do the trick?

I am using a usb cable to connect my cellphone to my pc. It is strange that this problem happend. In Pclinuxos 2009.1 and 2009.2 it just work fine. I just click click and there I go but in 2010 it gives problems. Is it because of the new kernel or kde 4? Last night I try the 2009.2 live cd and I connected to the internet. What is wrong with 2010?

I also get this- "Unable to open device /dev/ttyACM"- when I try setting up using the control center.

Not your phone make or model - but this is how I did it.

Maybe its just a lack of symlink? Run this in konsole

Code: [Select]

su -c "ln -s /dev/ttyACM0 /dev/ttyACM"
replace the ttyACM0 with the device that corresponds with Your modem.

When asked type in roots password. Then retry setting up the internet connection.

Hi Andy.
Thank you for the command line. It now works 100%. But when I reboot my pc and try to connect to the internet, it gives me the same error as previous. When 'n retype the "command entry", it work then. Is their away to make it stay forever?

Try adding this command as a last line to this file

Code: [Select]

/etc/rc.local

as root.

I have exactly the same issue here.
It's a fresh install off PCLinuxOS with Gnome. The phone is Nokia 5800 XpressMusic.
Just like the first post in this thread, I get "Unable to open device /dev/ttyACM"

I have not yet attempted to fix it, due to the fact that I have a program on my phone that creates a wireless zone around it. And I don't like to mess with config files when I don't have to.

I first discovered the problem on a train, with eight hours of boredom ahead of me. Fortunately i found that app for my phone.
