Hello

I have Kubuntu 7.04 and when i try and use the internet connection manager i know what its called it stays stook on 28% then stops connecting

Is this just my pc or is it a bug that i can get round please help

P.S: Here is the output this might help you

02:00.0 Network Controller: RaLink RT2561/RT61 802.11g PCI
02:05.0 Ethernet Semiconductor co, Ltd. RTL - 8139/8139C/8139 C+ (rev 10)

I think its said (rev 10) I'm not sure and it is a linksys wmp54g it says on the instruction manual and kubuntu autodetected it

This looks less like a NetworkManager bug and more like the kernel/driver or a hardware block getting in the way. With a Ralink RT2561/RT61-based WMP54G the usual causes are: no kernel driver bound, missing firmware the driver needs, or the card being soft/hard blocked (physical wireless switch). The answers from , and point the right directions (manual bring‑up, alternate GUIs, ndiswrapper), but start by confirming what the kernel actually sees.

Run these checks and read their output carefully (replace prompts as needed):

sudo lspci -nnk | sed -n '/Network controller/,+3p'
sudo lsmod | grep -i -e ra -e rt -e ralink
sudo dmesg | tail -n 200 | grep -i -e ralink -e firmware -e rt2x00

What to look for: a "Kernel driver in use" line (or none), module names in lsmod, and dmesg messages about "firmware" or driver errors. If the driver is present but the interface never comes up, check for a hardware/soft block (physical switch or rfkill) before removing NetworkManager.

If you want a persistent, NetworkManager‑free setup (so you do not have to re-run manual commands every boot), configure the interface in /etc/network/interfaces and point it at wpa_supplicant for WPA networks. Example skeleton—replace <iface> with your interface name:

auto <iface>
iface <iface> inet dhcp
    wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

If diagnostics show a missing or wrong driver: either install the correct firmware package for your distribution, use backported/updated wireless modules (or a newer kernel), or as a last resort try the Windows driver via ndiswrapper (the fallback mentioned). For quick testing, booting a modern live USB is often the fastest way to tell if a newer kernel fixes it.

I've experienced this problem as well on (K)ubuntu. I solve it by hit-and-miss; sometimes I'll try connecting through the terminal with

# iwconfig ath0 essid my-network
# dhclient ath0

Where ath0 is the name of your wireless device. Although this works, it tends to screw up Network Manager because it still thinks the device isn't connected. Sometimes I have to disable/re-enable the device and start all over again. Alternatively, try manual connection settings. It sometimes works for me.

I haven't looked into this issue any further on the web, but I suspect somewhere there's a bug filed, and (hopefully) a more reliable workaround.

yeah when I was installing ubuntu on my parents computer the wireless card refused to actually work. Try using wifi-radar. After a few tries it should start working...(or at least it started working for me)

When I installed ubuntu on my laptop, the wireless would not work for me either...I ended up using ndiswrapper and it worked fine for me...After reading the ubuntu forums it appears many people have had problems with wireless...

Yes, wireless is sometimes a bit broken on all ubuntu 7.04 based systems (they changed the way networkmanager works)

I got a realtek RT25something card and it worked under Edgy but not feisty or gusty

If it's a permanent problem, I would recommend removing the Network Manager scripts from the startup services. Then you can set up everything manually through the shell like I described in my first post. (And if you're really lazy, add those shell commands to your boot script).

You may also need to add/modify DNS information to your /etc/resolv.conf file to get the Internet working.

Debians networking works just fine, ubuntu usually gets issues liike this as its based on beta software

Getting a supported wireless card to work is a pretty simple problem, if your not willing to edit one file then maybe linux is not for you.

If you give it to me step by step

What are the results of running

iwconfig

at the prompt?

Member Avatar for Sturm

First disable the network manager. Then use Joe's solution:

# iwconfig ath0 essid my-network
# dhclient ath0

or use wifi-radar. Once you have created a network in wifi-radar press the connect button. It should connect to your network. If you are too lazy to do this everytime you boot up then add wifi-radar -d to your startup script.

Member Avatar for John A

I'd like to add a couple of notes. To disable Network Manager, you need to run the following commands (taken from the Ubuntu wiki):

sudo /etc/dbus-1/event.d/26NetworkManagerDispatcher stop
sudo /etc/dbus-1/event.d/25NetworkManager stop
sudo echo "exit" > /etc/default/NetworkManager
sudo echo "exit" > /etc/default/NetworkManagerDispatcher

Second of all, if you want to use my previous solution, using ath0 as the network device will only work if your wireless device is really ath0 ! I recommend first running iwconfig with no parameters to figure out the name of your wireless device.

yes. its usually the manufacturers name e.g my Ralink card is ra0
