iPhone looses connection / Internet Connection

16 06 2009

Today I had a strange behaviour on my iPhone 3G. When trying to open my emails I got a “no connection to the internet available” against the settings pane, which told me that my 3G Connection is configured and switched on. The only thing I was missing was the connection icon at the right of the provider logo. I tried to switch on and of 3G, checked my connection point settings, nothing helped. It seemed like the daemon responsible for the connections EDGE, 3G and WLAN died somehow. I restarted the device and everything was fine again. A few days ago I encountered messages like “Network Connection Lost” during the day. Has or had anybody out there similar problems??? iPhone 3G free for all providers, no jailbreak.





HUAWEI E220 Follow Up

2 04 2007

Again a shorty about the Huawei E220 and linux. Since my last updates of ubuntu 6.10 the E220 is always recognised the right way and usable right from the start.





Huawei E220 revisited

8 02 2007

Hi Folks. Finally I have finished my tests and scripting with the Huawei E220 USB UMTS Modem and Ubuntu Edgy Eft. Some conclusions can be made:

  1. have the modem plugged in on boot
  2. if you work continuous only with the modem work with suspend to disk mode instead of shutdown
  3. use the scripts I provide here
  4. if you unplug the modem so that kppp is hanging or the modem device is hanging you will only get it back to work with a reboot

I have done some scripting and tests. The modem is ready for working if you have more than one device named /dev/ttyUSB. If there is only one ttyUSB0 device it might not work at all. I have created a script which checks the number of ttyUSB devices if not a minimum of 2 devices exist the script automatically does the procedure described in my prior article about this modem. ATTENTION please follow exact the hints written to the console. The script has some built in sleeps and waits which have been tested to work quite well. So long.

Script for setting the pin, slightly modified: setpinpl.txt

Script doing all the other work: huaweish.txt

HINT: Please modify the entry with the pin code needed for your umts device.





Huawei E220 and Ubuntu 6.10

3 01 2007

I changed my mobile card due to a change of my notebook where the new one no longer supports pcmcia cards. So I switched to the Huawei E220 usb UMTS Modem. The drawback, it does not work from scratch, the benefit, the signal strength is much better.

So the device is recogniced as an scsi storage device if you plug it in.
You have to close all open windows showing content of the device and unmount the device.

call the follwing commands:

rmmod usb-storage
rmmod usb-serial

to unload the storage device, then call:

lsusb

and write down the vencor id and produc number of the attached device, then call

modprobe usb-serial vendor=<vendor id> product=<product id>

unplug the device, replug again and check that there are three usb devices calling:

ls -la /dev/ttyU*

if there are 3 devices you can use the device with kppp or wvdial. The modem device is ttyUSB0

ATTENTION: don’t forget to execute all commands with sudo

Vodafone GT 3G+ EMEA with Ubuntu 5.10

1 06 2006

Victory, after searching the web for about 2 weeks for HOWTO’s to install the vodafone gt 3g+ card with ubuntu for using in austria,I did it at the end. This should be a step by step description of what has to be done to get it work. This HowTo is for all user who have the vodafone model which does not register as usb devices. This type of card registers as pci device.

For details on how to get the thing working, see the attached files. For the content and functionality in the attached scripts I will take no responsibility for any harm and damage done to your system. I advise you to review the scripts before using them. Preconditions for the automatic activation script are:

  1. nozomi module (download and make, described in howto)
  2. kppp (sudo apt-get install kppp)
  3. zenity (sudo apt-get install zenity)

Resources:

Note:

Pleas run the activateVodafoneCard script with sudo, else it would not work correctly. So long and have fun ;-)
