can't get wireless internet connection on dell 6400

Asked by sandra mclean on 2009-11-19

i've got the laptop to recognise the wireless signal, but whenever i type in the pass word, and press apply,
it appears to have connected but then jumps back to a strange long password
this continually happens, so i now have to connect wirelessly
can anyone help with the problem please?
thank you
sandra

i've read through a few of the answers to similar problems but none seem to fit the problem exactly
thank you
sandra

Colin Ian King (colin-king) said : #2

Perhaps, you can do the following:

start up a terminal (Applications->Accessories->Terminal) and then run the following command:

iwevent | tee iwevent.log

Then can you try and login a few times. Then post the contents of the iwevent.log to this report so that we can see why the wireless is failing to associate.

peter b (b1pete) said : #3

Sandra, pls provide output of:

sudo iwconfig

to do that open a terminal, run cmd above and copy/paste output here; that'll identify your wireless interface.

if you already know the wifi interface then pls run

sudo iwlist <your wifi interface> scan

pls copy/paste this output too. that'll show your access points (SSID) in range and whether keys are on or off, then you'll have to find out from the ap administrator (it may be you too) EXACTLY the type and the key itself; that's the key that must be entered for that particular SSID for a successful connection.

sandra mclean (sandra-mclean2) said : #4

in answer to colin king's question
however the internet cable was unplugged at the time,
was that alright? or not?
ndra@sandra-laptop:~$ iwevent | tee iwevent.log
Waiting for Wireless Events from interfaces...

sandra mclean (sandra-mclean2) said : #5

in answer to peter's question
sandra@sandra-laptop:~$ sudo iwlist <your wifi interface> scan
bash: your: No such file or directory
sandra@sandra-laptop:~$

that was the result

peter b (b1pete) said : #6

two things pls.,

first, pls go to Applications --> Accessories --> Terminal --> double left click and enter at cursor on the new opened window

sudo iwconfig

followed by enter key then password when prompted (you'll see nothing when entered for security reasons) then enter key again; some output will be generated. pls copy/paste that output here. we'll continue after that.

sandra mclean (sandra-mclean2) said : #7

peter b (b1pete) said : #8

ok, that's good.

now, second, using same procedure as in my last post pls enter this time into terminal cmd as follows

sudo ifconfig

pls copy/paste output here. we'll continue after that.

peter b (b1pete) said : #9

Sandra, just for your info (I didn't have a lot of time when mailed out last post, sorry)

- yes indeed there is a wireless interface called/named

eth1

that shows up in your last post; (also pls notice the wired interface called eth0). we're interested in eth1 - this interface 'sees an SSID called "Nickname:" and is not associated with any access point

we'll try now to see what access points are within range with the following command - pls enter it into a terminal

sudo iwlist eth1 scan

copy/paste the output. btw, what ubuntu distribution/release are you using ? yo can find that by entering into a terminal cmd as follows

lsb_release -a

so, in summary, pls provide outputs of following three commands

sudo ifconfig
sudo iwlist eth1 scan
lsb_release -a

after I see the outputs we'll configure and bring up the wifi connection.

peter b (b1pete) said : #12

yes Sandra. v good and nice work!

now, to continue, first, your ubuntu wireless interface eth1 'sees' something like 7 access points (Cell 1 to 7) as you could see above and 7 ESSID's each corresponding to a 'Cell' number (ex ESSID named TalkTalk9f3kk is on Cell 01 and so on).

furthermore, pls notice on the above also that ALL 7 access points have Encription keys set (on) of various types (ex Cell 01 has

Group Cipher : TKIP
                        Pairwise Ciphers (1) : TKIP
                        Authentication Suites (1) : PSK

 and that Cell 01 has the best signal (92 out of 100%) and lowest signal noise. You can see now that, basically, there are out there within your eth1 interface range 7 choices to connect to the internet.

- now, PROVIDED that eth1 is properly configured, that is to say that to eth1 on your pc

is assigned one ESSID (ex TalkTalk9f3kk) AND
is configured to use the SAME key type and value as the one on Cell 01

that a connection to internet via say Cell 01 is just a matter of setting/configuring eth1 such that Cell 01 accepts and understands that your pc wants to become part of its secured, encrypted network. that's the idea behind having a secure network and pc and communication on the internet.

so, these being said, there are a couple of other things that you'll have to attend to

1 - pls provide output to

lsb_release -a

command so that I know what ibuntu release you're using - this is v important in order to solve the conn'n problem expeditiously and as easy as possible for you to get a good grasp how to handle future problems concerning wifi conn'n.

2 - you will have to find out from those access points administrators (at least ONE) the type and values of the encryption key that is set on that particular ap/SSID. without this piece of information you will not be able to connect wirelessly to internet through any of the Cells found by eth1 interface. it is quite possible that YOU are one of those administrators - in this case the problem becomes simpler (I do not know whether you are one of the admins of those 7 ap's).

I suspect that on Cell 01 you are the admin. if that is the case then you must know the type and the value of Cell 01 encryption key.; I hope that' the case - you can master/configure that access point.

so, to summarise, pls provide output of

lsb_release -a

command AND find out and be in possession of what Cell number and ESSID have what type and encryption key value (you do not have to tell them to me but you MUST have them handy to be entered on the eth1 interface configuration file). we'll continue after that.

peter b (b1pete) said : #14

ok Sandra, I could see that you're using Hardy release; I assume (pls make sure that that is so) that you also HAVE the other info handy ie an ESSID and the type and value of the encryption key of at least ONE of the Cells identified by eth1 interface scan above.

now, just o small digression from the task at hand, it concerns the relese you're using

 - the wifi configuration tool evolved quite a bit (now it is much easier for the users) in every new ubuntu release since hardy and there are quite a few releases available since; for your info, there are the following releases available : intrepid 810, jaunty 904 and karmic 910; I'm mentioning this so you may consider sometime an upgrade to, probably, the latest karmic release; however, this is not part of this ticket - it'll be the topic of another ticket if you need help in getting a new release installed.

back to the task ay hand; pls go to System --> Administration --> Network tab --> left double click on it, enter the password when prompted; a new window will open called Network Settings - you'll see four tabs inside the window called Connections, General, DNS, Hosts. the window will show the Connections tab open by default and in it you'll see at least 2 entries as follows

Wireless connection (eth1)
Wired connection

and probably a third entry called Point to point connection. we're interested on the first one - Wireless connection (eth1) - so, pls Unlock the window first in order to gain permission for editing then highlight it then press Properties button --> a new window will open called

eth1 Properties

that is the interface configuration window that we'll/you'll use from now on quite a bit anytime there is a need to connect to an access point. so, pls proceed as follows

step 1 - remove the tick mark from Enable roaming mode box
step 2 - enter the ESSID of one of the 7 Cells shown above in the Network name (ESSID) box
step 3 - in the box Password type just open it/drop down options will appear
step 4 - select the password/encryption key type CORRESPONDING to the ESSID entered in step 2 above
step 5 - in the box Network Password enter the password/encryption key CORRESPONDING/PROPER to the ESSID above
step 6 - in the box Configuration drop down select Automatic Configuration (DHCP) option
step 7 - click on OK button. a bullet running left ro riht will tell you that the interface is being configured for the ESSID entered above; it'll run a while - let it finish what it is doing - and upon ending, if everything was done properly, you'll se on the left upper panel on the desktop a blue icon like a row of stairs that tells you that your pc is wirelessly conncted to the internet.

if you left ckick on this icon you'll see the ESSID connected to your pc eth1 interface, among ther things. that is it, no mass no fuss.

I tried to be as detailed and clear as possinle; I also hope that you grasped how to change easily your interface connection anytime such move is needed in the future.

for now best of luck. keep us posted how things go - we'll get you over this hump.

a small mistake on the last post, sorry for it

....'you'll se on the left upper panel'......

should read

...'you'll seE on the RIGHT SIDE OF THE upper panel'....

dear peter,

thanks for taking the time to explain,
however i have followed the instructions, and the same error keeps occuring
i fill in all the information ie ESSID and password, select the auto configuration etc
as you've explained ,
the small box with the updating icon occurs, when i try to access the internet
it's impossible, says there's no network signal etc,
when i go bck to look at the box, it shows the password has mysteriously
changed to an impossible long one,
is there any way we can find out what the mysterious new password is?
Or delete it from the computer completely??
thanks
sandra

well, I'm affraid that you have to dig a little deeper.

first, let me understand, are you the administrator of any of the 7 access points that eth1 found within its range and are listed above?

if YES, which one of the 7 is ? just tell me the Cell number/ESSID.

before running the next command below pls check carefully the entries into eth1 configuration file/window - there must not be any quotation marks on any of the entries - ex; say you want to connect to Cell 1 then you enter in ESSID box TalkTalk9f3kk without any quotation marks and so on. the encryption key type and value MUST be the ones that show up in your router configuration. if any of these entries is mistaken there is no way of getting a connection.

then pls run cmd in a terminal as follows

sudo dhclient

and copy/paste here its output. we'll discus further after I see that output.

PS.
this is just for your help on how to 'dig deeper' into this matter. I hope that you're familiar how to log into that ap/router that you're the administrator of and temporarily remove any encryption keys that may be present in the router configuration. I can not help you in carrying out this exercise from this end - if you do not know how to do that pls ask your ISP to help you out; just explain it to him that you'd like for the purpose of checking your connection that you'd like to have no encryption keys temporarily present on the router. then, after the keys removed pls run again

sudo iwlist eth1 scan

that particular ap/ESSID must show this time NO encryption key present - it should show encryption key OFF. if that is so then pls go to Network tab as explained on my last post and configure eth1 such that NO PASSWORD shows on the box for that particular ESSID - see steps 3, 4 and 5 above. finish the configuration as stated above. if everything properly done you MUST end up with a connection to that ap/ESSID

Sandra, you have to log in the router that you're administrator of, if you are one of them, in order to reconfigure the router such that there are no encryption keys present and that there is no mac filter set for mac address 00:1c:bf:6b:fc:51 which is the wireless eth1 interface. your eth0 wired interface works ok and connects with no problems he way I see.

your router address is 192.168.1.1 so you'll have to log in with your browser using

http://192.168.1.1

then enter the name and password if any set and feel your way in its configuration; I say 'fell your way in' because this exercise is not a simple one - one must be familiar with router configurations, the details of removing set keys and mac addresses settings in order to check and obtain a connection wirelessly to the internet via a router. your best bet if you're not comfortable with this exercise is to talk with your ISP and ask for help; it must be done there.

looking at the overall situation I can say unmistakably that your wired and wireless interfaces are ok1 - both work as they should - the problem you're facing is configuring eth1 to work hand in hand with an ap/ESSID that it sees. you have two choices

1 - either log in the router that you're the admin of and temporarily remoe all keys and the mac filter then for sure, without any doubt, you'll get a connection then V V carefully relog into the router and set and MARK down the key type and its value and reconfigure eth1 with these newly set values that you're sure of.

2 - talk to any of the admins of the 7 ap/ESSID listed and kindly ask them to tell you the type and value of the encryption key on the router they manage. then configure your eth1 interface accordingly.

as I said several times before and say it again Sandra, it is mandatory to enter into eth1 configuration window EXACTLY the encryption key type and value of an access point within range doesn't matter which one - failing this there is no way to connect wirelessly to any ap and internet.

on one of my laptops I still have hardy installed and travel with it quite extensively. I use hardy quite often in connecting to internet in airports, cafees and hotels. the first thing that I ask the administrators is whether they have active ap's to connect to internet and second what is the ESSID (in case is not advertised/broadcast) and the afferent encryption key type and value. then it takes me a minute or so to configure the interface and there I go surfing without any problem; hardy is v good at that though not the simplest and easiest for the user as I mentioned.

I really do not know what to say at this time; you should endeavour to find out somehow the encryption key and value of any of the 7 Cells that eth1 sees and configure it accordingly. for sure you'll have success.

btw, did you try disconnecting (unplugging the cable) of the wired eth0 connection then boot your computer without it ? then check the network manager and see what it says ?

peter b (b1pete) said : #20

Sandra, re-reading the entire thread I just noticed that you never told me whether you are an admin of any of the 7 ap's listed. pls give answers to questions below

Q1 - are you an admin of any of the 7 ap's listed ? if yes, which one pls ?

Q2 - did you ever connect wireles successfully to the the ap that you're the admin of ?

 if yes, since when are you experiencing this failure to connect ?
 did you or anyone else reset de router and/or change its settings and/or the encryption password on it ?

Q3 - are you familiar and confident that You can reconfigure the router that you're admin of with v limited help ?

      if you are NOT the administrator of ANY of the 7 ap's listed

Q4 - did you connect successfully through any of the 7 ap's listed ? which one pls ?

for your info - I do not want to make you go into the system keyring and passwords and start roaming through passwords and/or deleting keys and passwords blindly - without having answers to above.

I will tell you more after I see the answers to above questions.

Can you help with this problem?
