Much easier to use kppp (you appear to be using SuSE). Or kinternet if it is still in SuSE, (haven't used it for a while). I'd be surprised if SuSE doesn't find it. You may need to :
lsusb

and post the output here. You may need to create a symbolic link as well:

ln -sf /dev/ttyUSB0 /dev/modem. You are essentially creating a serial connection. But the

internet speeds are broadband.

Cheers and please let me know how it goes.

It appears that the computer is identifying modem. I believe your problems relate to network settings. You need to have an IP address which is based on your computer's ethernet card. You need to be able to setup both network card and modem, assuming it is a standalone computer with just the USB E220 modem. Without the network card configured you have no internet 'address' or IP. Use YaST to check these out and configure.

You can't ping without a connection. Pinging doesn't setup the connection, kinternet or kppp does.

To be honest you may be better to try to understand networks and setting up connections by reading internet articles [on another computer] or books that you can understand, as you appear to be lacking a basic understanding of these.

I know that just giving a ping command will not enable a connection...
I have installed its driver...and also the IP was set...and then pinged it...

To be frank...Iam not a network admin...but I do have a basuc knowledge..on networking..

If you do understand networking then you need to be more clear in your posts about what you are doing, readers aren't mind-readers who understand what you are on about by

"I just checked it by removing my ethernet cable and just
ping www.google.com" ?? Ping will not work if you are not connected!!

If you want to get the thing working I suggest you read what I've written and try it. Things don't just happen 'automagically' as they might in Windows where plugging the modem in starts an auto script. Although Ubuntu 8.04 comes close to this.
