problems with WEP connection

Re: problems with WEP connection

thanks alot both you grey and snowhog, I did follow everything and yes the problem was about the root privilege.
then, I added the file and the option line,
after that, i did a reboot, sudo dhclient wlan0, and after that iwlist scanning gave me this result:

linda@linda-VAIO:~$ iwlist scanning
lo Interface doesn't support scanning.

eth0 Interface doesn't support scanning.

wlan0 Scan completed :

so basically my essid is listed in the scan, but why I am still facing the problem that it gets stucked on setting network address, and keeps prompting and asking for my WEP key?

Re: problems with WEP connection

My wifi quaility and signal strength is:

Quality=70/70 Signal level=-23 dBm

You quality not good, signal strength even worse.

0 dBm = 1 milliwatt of signal strength
-10 dBm equates to 0.1 mW
-20 dBm equates to 0.01 mW
and so forth.
Some of my neighbors wifi's show stronger signals than yours.. How far are you from your wifi and are there any walls between you and it, especially walls with metal foil linings.

Are the antennas on your wifi securely screwed on (or tightened)? Are they orientated correctly?

Re: problems with WEP connection

IIRC, WEP doesn't like an encrypted key, or KNetworkmanager doesn't like an encrypted WEP key. I may be wrong, but...

Re: problems with WEP connection

actually I'm sitting in my room so its only one room away from the modem. the signal strength sometimes is stronger and sometimes weaker, but the point is, it does not work any time at home, nor with any other modem that uses WEP encryption key. besides, my other OS does not have problem connecting to the modem, and even I use linux-backbox, and it easily can connect to it... it should actually be something with knetworkmanager...

Re: problems with WEP connection

Perhaps you should try wicd.

If you do, then install all of the wicd packages first,, then delete everything associated with knetworkmanager and network-manager, then reboot and run sudo apt-get autoremove
Then run wicd and configure your connection. If you get a "bad password" it is because you haven't removed all of the knetworkmanger components.

Re: problems with WEP connection

ok I did all that, still got problems with WEP. and not just for connecting to my own modem, but any where else that uses that encryption. for example now im connected to WPA2 with no problems and I can connect to this using any network manager. and anyway although I did unistall all other packages, now I get the "bad password" that you mentioned earlier.
thought maybe I have wrong packages installed so in package manager I tried to search for anykind of network package installed and found out these are installed on my system (there were alot but i listed down those which might end up to a clue):
wicd network manager
python-wicd
wicd-daemon
glib-networking
kdenetwork-filesharing
libqt4-network
libqtscript4-network
avahi-autoipd
avahi-daemon
avahi-utlis
ifupdown
iproute
iptables
iputils-ping
iputils-tracepath
isc-dhcp-client
libnm-glib-vpn1
libnm-glib2
libnm-util1
libnspr4
libnss3
libntrack-qt4-1
libntrack0
libsnmp-base
libsnmp15
net-tools
netbase
netcat-openbsd
pythn-wicd
rfkill
tcpdump
wicd-daemon
wpasupplicant

Re: problems with WEP connection

I've pasted a screen capture of the wicd apps to install.

Re: problems with WEP connection

ok, I did install those, still cannot connect. it gets stock in obtaining IP address and gives error indicating that it couldnt obtain an IP address... Im really getting dissapointed...

Don't get discouraged. Things generally work out.

There is a possibility that some of KNetworkManager and its stuff is still in your system, which usually shows up as a failure to get an IP address, or "bad password". You can open Synaptic and enter "network" in the search bar, then click on the little header box at the far left of the list of apps. That will sort it, putting the installed apps (green blocks) at the top and the rest down below. Look through the list of installed, network related apps and see if any look like they are part of KNetworkManager. Selecting one and looking at the description can help.

Also, there is a possibility that your wireless router isn't configured to accept WEP encrypted keys.

First, what is the make and model of the wireless router you are using? Some wireless routers allow encrypted WEP and some do not. Here is an example of how to set WEP encryption up on a D-Linnk router. http://spotlight.getnetwise.org/wire...wep-passwd.php

ok, i did that, firstly maybe I should mention I do not have Synaptic, but I use the KdePackageKit. the installed packages that were listed under network seach are:
glib-networking
kdenetwork-filesharing
libqt4-network
libqtscript4-network
i did remove all that I thought are related, these are the remaining ones im not sure about.

Also, there is a possibility that your wireless router isn't configured to accept WEP encrypted keys.

I dont think thats the case, because other distros and OS do not have any problem connecting to same modem.

actually I checked, this is the specifications of the modem:
Hardware model: WIXM-171
Firmware version: v1.3.9.1-g1.2.9-p1
and the network settings are as follows:
security mode: WEP
Auth mode: open
Encryp Type: WEP
Key index: 1
WEP key: "my key"

Re: problems with WEP connection

Wow, the small amount of information shown by Google for "Packet one WIXM-171" is remarkable. It appears to be a Chinese modem. Where did you get it?

Others are using the brcm 4313 wireless chip without problems. Snowhog just reported that the new HP p7 laptop that he bought had that wireless and that Kubuntu recognized it out of the box and it is working fine. I could find no manual for it online so I could not determine if it had a WPA capability as well, which you could test. So, my conclusion is that your laptop wireless chip and its driver are OK, but your connection to your wireless modem is less than that. The scant references to that modem listed a more recent version of the firmware, but I could find no location from which to download a firmware update. So, I am out of suggestions at this point. Sorry..

Perhaps it might be more helpful to get a different modem. TPLink, or Linksys. If you do go that route you should make sure that the new modem is IPv6 capable. Most modems that people use are not, so sooner or later a LOT of folks are going to have to upgrade to an IPv6 modem.

Re: problems with WEP connection

thanks for your effort and guidelines grey... yes, since I'm living in Malaysia, the possibility for it being chinese is pretty high. however, at this point I do not have any choice to change the modem since the modem is offered by its relevant ISP and it employs WIMAX tech without usage of LAN, hence I cannot swich to linksys and such...
it looks like im not able to use kubuntu at home and thats really sad...
but its a wonder, how come other distros can connect to same modem?
and also, why I cant connect to any place using WEP encryption (such as cybercafes, coffeenets) regardless of modem brand?

Re: problems with WEP connection

I wish I could answer that but not being able to set at your machine and explore some things ....

If you have another distro in mind that connects and uses your modem just fine and that is important to you then I'd use that distro, especially if it offers KDE4. You don't have to be running Kubuntu to ask questions here. A lot of us play with more than just Kubuntu.

You can try LiveCDs of each one. The first I'd try is Linux Mint KDE, because it is based on Ubuntu. To get away from deb packages you can try Fedora or openSUSE. They both offer KDE4 (if that is your desktop of choice).

The way your ISP sets things up is curious. They didn't connect their wire to a modem, allowing you to connect a wireless router to that modem? Does their cable connect directly to the input IP port on the WIMAX?

actually, there is no cable... they have eliminated the conventional methods of ADSL. I think you might find more info here: http://en.wikipedia.org/wiki/Packet_One_Networks

Ah, I see. It is just a microwave receiver employing the WiMAX 802.16 standard.
This web site might be useful: http://www.linuxwimax.org/Hardware
But, at first glance, it doesn't look like your hardware is supported, yet.
