 |
|
As the topic says, for some reason or the other, NM does not connect to the wireless network here at my university. Here is the info about the connection:
| Code: |
eth1 Scan completed :
Cell 01 - Address: 00:0D:28:73:9F:3A
ESSID:"JACOBS"
Protocol:IEEE 802.11b
Mode:Master
Frequency:2.442 GHz (Channel 7)
Encryption key:off
Bit Rates:1 Mb/s; 2 Mb/s; 5.5 Mb/s; 11 Mb/s
Quality=93/100 Signal level=-38 dBm Noise level=-37 dBm
Extra: Last beacon: 90ms ago

What network card are you using? Paste the output of...
What kernel drivers/modules are you using? The following shows what modules are loaded...
...but your driver my be compiled into the driver itself.
What kernel version are you using?
All useful information that will be required to help troubleshoot.
There are a number of people (myself included) having problems with kernel 2.6.24 and various broadcom43** series of cards and drivers (see the Native Airport Extreme thread and various others in the forums). |

Oh yes, other useful information would include the output of...
| Code: |
# ifconfig

Okay so you've an Intel Pro/Wireless 3945 card..
| lspci: |
0c:00.0 Network controller: Intel Corporation PRO/Wireless 3945ABG Network Connection (rev 02)
|
This is connected using the ipw3945 module that you've loaded, and you have ieee80211 and ieee80211_crypt modules are dependent on this...
| lsmod: |
ipw3945 91360 0
ieee80211 23304 1 ipw3945
ieee80211_crypt 2688 1 ieee80211
|
ifconfig looks okay, but your failing to associate with any access points (iwconfig).
Have you tried connecting manually?
Are there any errors in dmesg that relate to your card and the cards driver? |

Only works when you add NetworkManager to default runlevel! Works now!

Cool, glad its sorted. Hadn't come across NetworkManager before reading this thread, looks useful, and will try it out (if I ever get my wireless card working again!). |

Argghhhhhh! I hate network manager, actually I have always done so. Have a look here and here.
This thing does not work for me, now. Kinda funny, the way it works. I can connect to the wireless in some classes and some places I can not. And there is nothing wrong with the wireless because others using Linux can connect to it. I think NM hates me. Why is WICD not in portage?

So what, if is not in portage. Just downloaded the source, unzipped it and did a python setup.py install it. And here I am, using wireless thanks to WICD.
So, my advice to others is throw network manager out of the window and install wicd right now.
Cheers to WICD and its developers!

Theres an ebuild in bugzilla if you want to keep things clean and 'gentoo' |

Ahh, if I had known that, I would have used the ebuild. Still it works pretty nicely therefore I do not feel the need to first remove and then use the ebuild!

And just another addendum, there is some package that installs as a dependency of the networkmanager use flag that WICD depends on. I have not yet figured out what that package is, so to keep things simple the network manager use flag is enabled, every package that installs with it is installed (which includes NM) and WICD is installed as well. But it is WICD that is there in the default runlevel and NM is not being started. This makes everything work.
I guess NM is just punishing me for hating it.

If anyone is interested, I got NM to talk to our WEP'd access point by loading the ieee80211_crypt_wep module.
Up until then I got no error, just entering the password over and over. Thanks to the guy above, he mentioned looking at dmesg and there was the error, module not loaded.
Why the module doesn't get loaded automatically, I'm not sure. |

OK, I figured out that WICD depends on the package dhcp, so to make it work, dhcp (that is the name of the package) needs to be installed. No need of any network manager support anywhere.
