I am using Fedora 8 x86_64 (kernel 2.6.23.14-107) on my Dell Vostro laptop which has a Broadcom Corporation BCM94311MCG wireless mini PCI lan device which has been automatically detected and uses the b43 wireless driver.
I have configured the wireless device wlan0 using a static IP address and have provided the ESSID, CHANNEL, MODE, RATE settings. The wireless device comes up and gets associated with the Access Point / Wireless Router when the system is started. However if the wireless router is restarted the wireless device on the laptop fails to associate with it again and I have to restart the network service in order to connect to it. If I remember correctly, the Intel Centrino ipw2200 device on my older laptop never had this problem and nor does a PCI wireless card (Realtek 8180) which I have configured using ndiswrapper. What could be the reason for this problem ? Any tips or suggestions ?
Use NetworkManager.
Good advice. Alternatively you could use wpa_supplicant (whether or not you are using WPA encryption), or you could simply do "iwconfig wlan0 essid $ESSID" whenever you detect that your AP has been reset.
If you want a technical explanation...the hardware in question is "soft MAC" device which uses the mac80211 infrastructure in the kernel.
Isn't this one of the things that are gonna get improved with the new driver in kernel 2.6.25?
