Wireless Nic (d-link Dwl-g520) Not Working After Update

Last night (around 10:00 pm on April 12, 2008, EST) I installed few updates (didn't check what were those, but no post-install reboot were needed). Today, when I started the PC (only connected through wireless) it didn't connect the network. Even not able to ping the router (home network @ 192.168.0.1).

I am using:
0) Desktop: Intel P-II
1) Kernel: 10.3-2.6.22.17-0.1
2) Wireless card: D-Link Air Plus DWL-G520
3) Driver: Madwifi

I think its an effect of the update that I did last night. Please help me what should I now ?

re-install madwifi,see if that helps

Reinstall didn't help.
I found a temporary solution with following steps (but it is NOT PERMANENT )

1) Assign the Wireless Interface Firewall Zone to "External" from YAST (Yast Control Centre -> Network Devices -> Network Cards -> Network Settings -> Configure -> General -> Firewall Zone -> External)
2) Configure the Wireless Interface Firewall Zone to "External" from "Firewall Configuration" (Yast Control Centre -> Security and Users -> Firewall -> Interface -> Change -> Interface Zone to "External")

But, if I reboot the PC, then I find the Network Device's Firewall (#1 above) configuration resets to " No Zone, All Traffic Blocked".
Now I strongly believe that it is happening for "Firewall Setup whiich might have a upgrade yesterday.

Please let me know how to make the above configuration permanent ?

Try Yast>Security>Firewall>Interfaces

Try Yast>Security>Firewall>Interfaces

I tried and it doesn't help.
Please help me to save the configuration PERMANENT.
