Wireless Network Setup

Hello all,

I have a Compaq Presario 2100 notebook with an AMD Athlon XP-M processor.
The distribution that I have is : Fedore Core 2.6.8-1.521
I have Broadcom 94360 wireless card and Linksys 54G router.
I have the latest ndis wrapper 11.0 and with some difficulty have managed to install the drivers for the wireless card and the wireless device is active.
My notebook does show up on the DHCP clients table on the Access Point.
But I can not browse on the internet. I can not ping to any address including the access point.
But ifconfig shows some packets being sent and received.

Code:

/sbin/ifconfig

 

wlan0    Link encap:Ethernet  HWaddr 00:90:4B:41:C6:7F

          inet addr:192.168.1.102  Bcast:192.168.1.255  Mask:255.255.255.0

          inet6 addr: fe80::290:4bff:fe41:c67f/64 Scope:Link

It can scan for wireless networks and does detect a bunch of them around. But no incoming or outgoing data. The wireless network is open but is restriced by MAC address.
The ifcfg-wlan0 is as follows:

Code:

#Wireless NDIS Wrapper Config

DEVICE=wlan0

BOOTPROTO=dhcp

HWADDR=00:90:4b:41:c6:7f

ONBOOT=yes

TYPE=Wireless

DHCP_HOSTNAME=HAL2003

MODE=Managed

ESSID=Akashwani

CHANNEL=6

IPADDR=192.168.1.102

DOMAIN=

NETMASK=255.255.255.0

USERCTL=yes

PEERDNS=yes

GATEWAY=192.168.1.1

IPV6INIT=no

RATE=Auto

MII_NOT_SUPPORTED=yes

It would be great if someone could help me out here. Suggestions and pointers highly appreciated. I can put up more data in the post if it is required.
Thanks

What is the ping error? Destination unreachable?
If so, you might want to check your routing table (the cmd is route).
Also, maybe iptables is dropping your packets?
I am going to assume that your MAC is included in the AP's allowed list.
To exclude MAC filtering as your point of failure, you should disable it and then see if you can associate to the AP.
Also, you might want to check your logs (syslog, daemon.log, messages, etc..).
If you really want to get funky, install ethereal and REALLY see what's going on with your packets...

Ignore those Tx and Rx, they dont mean that the card is communicating with anything, background noise if anything. The problem here is your IP i think. What happens when you

Code:

ifdown wlan0

followed by

Code:

ifup wlan0

???
Also, you say Broadcom 94360? I'm guessing you mean 94306 in which case you should make absolutely sure you are using the drivers from the ndiswrapper wiki card list and not other ones from manafacturers sites. These often dont work as I discovered to my cost. If it turns out you are not using the right drivers then remove the current drivers, uninstall ndiswrapper and repeat the process with the correct drivers.

Here, I'll even post the link coz I'm nice like that.

Thanks for replying guys.

The wi-fi link is working. I don't know yet what the problem was but it is working fine now.

Thanks and cheers
