Default Wireless no longer working

Since the latest updates to F9 my wireless no longer works.* This seems to be a common theme.* Anyway the following messages appear in /var/log/messages and I'm curious as to what they mean

Jul 29 18:07:42 localhost kernel: iwl3945: No space for Tx

Jul 29 18:07:42 localhost kernel: iwl3945: Error sending REPLY_LEDS_CMD: iwl3945_enqueue_hcmd failed: -28

They occur regularly, probable due to NM managing the device.* When I try to start it via ifup wlan0 it fails.

My wireless dhcp server showst the following messages:



WLAN client: 00:1B:77:17:F4:7C, associated to wlan network

WLAN client: 00:1b:77:17:f4:7C, disconnected from wlan network. Initiator: client. Reason: Leaving the ESS



The client side shows



Jul 29 18:25:45 localhost dhclient: DHCPDISCOVER on wlan0 to 255.255.255.255 port 67 interval 15

Jul 29 18:26:00 localhost dhclient: DHCPDISCOVER on wlan0 to 255.255.255.255 port 67 interval 10

Jul 29 18:26:10 localhost dhclient: No DHCPOFFERS received.




I also have several related questions:

*1) Why does NM even try to do something with the wireless device when it is not marked to be activated on boot?* I don't need to be active on both the wired and wireless interfaces at the same time


*2) Why are the activate and deactivate buttons greyed out when I start system-config-network?* This the case for both the wired and wireless interfaces.

The only way to start the wireless (and have it fail) is to do ifup wlan0.


*3) I have both wired and wireless interfaces.* The system is normally connected via the wired and gets its address via dhcp from my server.* One of the pieces of information provided by my dhcp server and received by NM is the host name


Jul 27 12:10:44 localhost dhclient: DHCPREQUEST on eth0 to 10.0.0.70 port 67
Jul 27 12:10:44 localhost dhclient: DHCPACK from 10.0.0.70
Jul 27 12:10:44 localhost dhclient: bound to 10.0.0.4 -- renewal in 2975 seconds.

Jul 27 12:10:44 localhost NetworkManager: <info>* DHCP: device eth0 state changed bound -> renew
Jul 27 12:10:44 localhost NetworkManager: <info>*** address 10.0.0.4
Jul 27 12:10:44 localhost NetworkManager: <info>*** netmask 255.255.255.0

Jul 27 12:10:44 localhost NetworkManager: <info>*** gateway 10.0.0.100
Jul 27 12:10:44 localhost NetworkManager: <info>*** hostname 'peglaptop10'
Jul 27 12:10:44 localhost NetworkManager: <info>*** nameserver '68.2.16.25'

Jul 27 12:10:44 localhost NetworkManager: <info>*** domain name 'homenet10'
Jul 27 12:10:45 localhost NetworkManager: <info>* Policy set (eth0) as default device for routing and DNS.

Yet when I login after booting the system the host name is set to localhost.* Even if I set the hostname to peglaptop10 using


hostname peglaptop10

the next time I reboot the host name is back to localhost.

*4) How do I fix the following selinux problem which occurs when I do

ifdown eth0

rm: cannot remove `/etc/resolv.conf.predhclient.eth0': Permission denied


I get an alert from selinux which I have attached.* Also when I restart the interface

ifup eth0

I get the following even though the interface comes up.

[root@localhost opt]# ifup eth0

Determining IP information for eth0...dhclient(21974) is already running - exiting.


This version of ISC DHCP is based on the release available
on ftp.isc.org.* Features have been added and other changes
have been made to the base software release in order to make

it work better with this distribution.

Please report for this software via the Red Hat Bugzilla site:
*** http://bugzilla.redhat.com

exiting.
*failed.

And BTW dhclient is not running after I do the ifdown.* I assume this is related to NM managing the interface.



Any thoughts and assistance are appreciated.

Thanks.
Paolo
