Trouble connecting to the internet using Wifi

lhorace · 09-24-2009, 12:15 PM

Hi,

Start first with, I'm on Fedora 11 and my desktop is KDE. Fresh install, now I have been having trouble keeping consistent connection to the internet or webrowser would pause before initiated a connection to the web server. I contributed this problem to nm-applet because in the same location, using Fedora 10 previously and knetworkmanager, I had never had this problem. So I figured I would remove nm-applet and install knetworkmanager.

Code:

sudo yum install knetworkmanager

Well it installed kde-plasma-networkmanager instead, after further research, fedoraproject had decided to drop knetworkmanager in F11 for kde-plasma-networkmanager.

Then

Code:

sudo yum remove NetworkManager-gnome

I added the networkmanager to my KDE panel, tried to connect to a access point and got this

Code:

Sep 24 01:02:53 lutchy NetworkManager: <WARN>  connection_get_settings_cb(): connection_get_settings_cb: Invalid connection: 'NMSettingConnection' / 'id' invalid: 1
Sep 24 01:02:59 lutchy NetworkManager: <WARN>  wait_for_connection_expired(): Connection (2) /org/freedesktop/NetworkManagerSettings/3 failed to activate (timeout): (0) Connection was not provided by any settings service

Restarted NetworkManager, Network, and computer few times, didn't remedy the problem. rmmod and modprobe ath9k, still didn't remedy the problem.

I went to system-config-network, deselect manage by networkmanager. Went to wireless settings, specified access point 'linksys', set everything to auto... Went back to activated wireless device.

Got something like, Attempting to determine ip info...Failed, to that degree.

I tried

Code:

sudo iwconfig wlan0 essid 'linksys'

then

Code:

sudo iwconfig wlan0

It should have printed ESSID='linksys' and other info, well ESSID, magically disappeared.

I did

Code:

sudo iwlist wlan0 scan

Got my access point info, and address...

When I did a man iwconfig, it said you can force your wireless device to connect to access point by issuing this command...

Code:

sudo iwconfig wlan0 ap XXXXXXXXXXXXXXXX

Nothing happenes, so I issued this command

Code:

sudo iwconfig wlan0

and says it's not associated and since ESSID has disappeared, I cannot tell you if ESSID is set the right access point.

I have google'd how to manually connect to a access point through a command line and tried all suggestions and still no go.

I tried

Code:

ifup wlan0

after I issued the iwconfig command and it still failed. I know about wpa suppliant, but there should be a way to connect to a access point with out the need for wpa suppliant, especially when the access point is not encrypted. If there is an another utility to connect to a access point without the need for NetworkManager, knetworkmanager, nm-applet, I would appreciated if you let me know. Or another nm-applet equivalent.

And if someone could tell the proper procedures to connecting to a access point through a terminal. Would be helpful too...

Does your access point have security enabled like WEP, WPA, etc?

lhorace · 09-24-2009, 12:47 PM

No security, it's open network provided by the community. I can connect to the same access point through a live-cd.

trist007 · 09-24-2009, 12:53 PM

Write down your essid and MAC address of your access point after doing

Code:

sudo iwlist wlan0 scan

then do the following

Code:

sudo iwconfig wlan0 essid <essid>
sudo iwconfig wlan0 ap <macaddress>
sudo dhclient wlan0

lhorace · 09-24-2009, 12:59 PM

should I put the essid or macaddress in quotes.

trist007 · 09-24-2009, 01:00 PM

no u don't need to

lhorace · 09-24-2009, 01:02 PM

i'm on Fedora 12 alpha live-cd now, i'm going try with this version and see if it works...

As you can see, ESSID went missing...

You're running as root so you don't have to include sudo in every command. You should disable network manager, don't need that and it's interfering with dhclient.

lhorace · 09-24-2009, 01:51 PM

i'm going to be heading in to work now... When I get home tonight.. I will disable networkmanager, and try again.... I know I didn't need sudo.

fib11235 · 09-24-2009, 02:04 PM

I'm afraid your issue is driver. Show me what returns 'lspci' and what driver do you use (if you don't know show 'lsmod' return).
