How To: Manual Network Configuration without the need for Network Manager

[twistbit]

I have a Palm Tungsten C and seem unable to connect to my BT Voyager 2500V router, I have a laptop and two PC one wireless and one wired. These all work fine, any clues or advice would be very much appreciated.

I have contacted Palm and BT who seem unable to help, my Palm seems to recognise the Router but will not connect to the internet.

Hello,

Read the article, set it all up.

ap_scan=1
ctrl_interface=/var/run/wpa_supplicant 

network={
        ssid="lacasa"
        scan_ssid=0

        key_mgmt=WPA-PSK
        psk="mypass"
        pairwise=TKIP
        group=TKIP

Then when I run the command "sudo wpa_supplicant -w -Dwext -iwlan0 -c/etc/wpa_supplicant.conf -dd" I get the following output:

After this it goes on trying to connect a few times more failing.

Can anyone explain what I am doing / is going wrong?
I also tried the ndsiwrapper for -D.

Thank you for your time.

Hello,

I have been using the manual configuration to get a conenction.
This is my rc.local

ifconfig wlan0 up
dhclient -r wlan0
iwconfig wlan0 mode Managed essid "onone" key 443c6a1426 open
dhclient wlan0

Network manager does not work, nor does wicd.
This is due to my wireless card being its self. The only way i can make an connection is by iwconfig key open . its the open which makes the conenction. Network manager just loops around.

But the thing is,
If I have a period of inactivity. maybe 10 mins..
It drops the connection. And I cannot reconnect. even by running the commands again. No connection.
I have to restart to connect.


Please help me here. I really need help!

[kevdog]

You need closing brackets in your config file:

ap_scan=1
ctrl_interface=/var/run/wpa_supplicant

network={
ssid="lacasa"
scan_ssid=0
proto=WPA
key_mgmt=WPA-PSK
psk="mypass"
pairwise=TKIP
group=TKIP
}

Notice the last closing bracket which you didnt post.

[nomaddog]

I recently installed Ubuntu 8.04 with Wubi and I've been trying to get my wireless connection, but have been unsuccessful. I followed the step-by-step guide, but alas, no connection. Here is some info about my settings. Please let me know what I'm missing. Thanks in advance.

Hmm try with unencrypted first -- always do a stepwise confirmation to prove the driver is working before adding security measures.

[nomaddog]

Ok, I followed the unencrypted how-to and still nothing. Here's the results of the step by step.

Hello,

I have recently bought a Dell M1330 with Ubuntu 7.10. I am having an issue with the wireless connection. During boot it gets stuck at a place, while the wifi light keeps blinking on and off. After around a minute of this the boot continues but the wifi light keeps blinking with no internet connection. I have to run

sudo /etc/init.d/networking restart

to get the internet connection working. Although it works, but it is a bit irritating. Is there anything I can do to avoid this boot problem.

Thanks.

What driver/card/chipset are you using? Also router type.

[nomaddog]

Driver being used is Ndiswrapper+bcmwl5. Card is a Broadcom BCM94311MCG wlan mini-PCI. Router is a Linksys WRT54G v2.2. I hope I didn't muck something up by ndiswrapper. I was following another how-to on getting this specific card to work.
