Bug Description
This problem has occurred ever since I've started using network-manager.
Hardware used:
D-Link DI-624 Access Point.
D-Link DWL-g520 wireless g PCI card (atheros chipset based).
wireless device: ath0 (Atheros AR5212 802.11a/b/g NIC)
drivers used: madwifi
Encryption: WPA2 encryption (AES PSK)
Package versions used:
network-manager 0.6.1-0ubuntu4
network-
wpasupplicant 0.4.8.1build1
linux-
The wireless connection is able to be established the first time, but from then on, it suffers from connectivity issues, disconnecting and reassociating nonstop. Before installing the network-manager package, this network setup worked fine with no connectivity issues. The PC is a desktop, and niether it nor the AP has been moved, so it's not a signal issue caused by distance/placement.
Before using network manager, my wpa_supplicant.conf file looked like this (private info x'ed out):
-------
ctrl_interface=
ctrl_interface_
eapol_version=1
ap_scan=1
fast_reauth=1
network={
ssid="xxxx"
key_mgmt=WPA-PSK
proto=WPA2
pairwise=CCMP
psk=xxxxxxxxxx
}

Attached is a log of a wpa_cli session in which it logs the many many disconnects/ reconnects, as well as some failed attempts at connecting, where I ended up doing one of the following:
1) click on the applet, and click on my AP's SSID to reconnect
2) close the applet, close the kde wallet, and restart the applet to reconnect
3) manually issue commands to wpa_supplicant through the client interface
All of these attempts resulted in temporary relief, until the next disconnect. Disconnects seemed random, at first it would at least stay on for about a minute, with intermittent disconnects/ reconnects thereafter. wpa_supplicant. conf -B -w
As mentioned earlier, I have had no problems other than having to manually run:
wpa_supplicant -iath0 -dmadwifi -c/etc/
sudo invoke-rc.d networking restart
On every restart (Somehow I couldn't get wpasupplicant to run on boot... something wrong with the rc.d scripts). The signal strength was very good both in windows on the same machine, as well as while using wpasupplicant and the madwifi drivers before due to having a high gain antenna attached to the PC's wireless card. Perhaps the versions of these differ between those used for the network-manager package, and those previously installed.
