Integrated Broadcom 4311 on Acer 5315 with Ubuntu 7.10


I have installed a Ubuntu 7.10 on a Acer 5315 with a "Broadcom 4311" and have trouble using the wireless module. The Card is seen by the kernel as eth1. I try to manually change the options using the man pages and iwconfig since configureing the card from the desktop does not work at all. In manual mode all the values are set, except one.

Access Point: Invalid.

The eth1 prints no scan results.
I tried to scan in windows vista and succesfully scanned several networks.

This is my current configuration.

*-network
description: Ethernet interface
product: NetLink BCM5906M Fast Ethernet PCI Express
vendor: Broadcom Corporation
physical id: 0
bus info: pci@0000:05:00.0
logical name: eth0
version: 02
serial: 00:1b:38:2b:19:62
capacity: 100MB/s
width: 64 bits
clock: 33MHz
capabilities: pm vpd msi pciexpress bus_master cap_list ethernet physical mii 10bt 10bt-fd 100bt 100bt-fd autonegotiation
configuration: autonegotiation=on broadcast=yes driver=tg3 driverversion=3.77 latency=0 link=no module=tg3 multicast=yes port=twisted pair
*-network DISABLED
description: Wireless interface
product: BCM94311MCG wlan mini-PCI
vendor: Broadcom Corporation
physical id: 0
bus info: pci@0000:06:00.0
logical name: eth1
version: 01
serial: 00:1c:26:5c:88:22
width: 32 bits
clock: 33MHz
capabilities: pm msi pciexpress bus_master cap_list ethernet physical wireless
configuration: broadcast=yes driver=bcm43xx driverversion=2.6.22-14-generic latency=0 link=no module=bcm43xx multicast=yes wireless=IEEE 802.11b/g

The driver is installed out of the box, the card currently is set in roaming mode, the info above was taken with that roaming mode active. I took it of from roaming mode, enterd the values manually, like the essid and other stuff and that was it. It did not worked, then I tried to do the same thing from the console only this time using iwconfig.

From the log it seems that the card is disabled, since it is in roaming mode. How do I enable it? And what is this roaming mode? I took it off, entered manual mode, entered options, but it appears it is still disabled!

OK is the router you accessing have any security up like WEP, WPA, WPA2, mac or ip filtering? If so disable all that and make sure dhcp is enabled on it.
Try making a dhcp connection.

If still no luck then you may be experiencing the issue others have with Broadcom 43xx nics and the bcm43xx module. What most do when having this problem is blacklist bcm43xx module and then use ndiswrapper with the windows inf driver of the nic.

Many post explain this type of setup using the search tools.

Yes, I have a MAC Filter with WPA2 with hex passkey, with hidden ESSID and DHCP enabled. I cannot disable the security for the router since I live in a high WiFi activity area, and dont want others to leech my bandwidth.

Can you point me to a specific direction? The search tool did not return anything pertaining my Broadcom 4311. Also ... what do you mean by saying to use the inf driver on the nic? Is this even possible?

Using the search tool here will show many post on this subject.
I would at least for brief amount of time make the connection as basic as it can with no security just to see if the bcm43xx module will even work. Granted even though wpa2 is more secure it is easily cracked these days. Then one can start enabling security back then resolving issues around getting those items working. Not sure on support for bcm43xx module with wpa_supplicant. Have to goto their site and see the supported modules for wpa_supplicant.

Well, strange thing. I need the BMCWL6 driver that originally comes with windows vista for the ndiswrapper to work. However a broad search in my Vista system did not revealed any .inf files that are greatly needed for the install. Any ideas?

No ndiswrapper does not support promisc mode. As for scan you should at least find access points as far as that goes.

I installed ndiswrapper with the windows drivers found on the forums. I also installed with the drivers that came on my CD. The module is loaded at bootup. The only problem is a ndiswrapper -l lists that the device is present, however an iwconfig does not show anything.
Any ideas?

Well its not going to find a hidden essid to start with.
Have you configured wpa_supplicant to wpa2 and either ccmp or tpik?
Not knowing Ubuntu I would guess wpa_supplicant is installed with all nic module supports.
Try pinging the routers lan side IP.
If that works and can't resolv a domain name address then maybe a DNS setup issue.

This is why I said make the connection as simply as possible. No security and dhcp enabled. You may leave dhcp off and use a static IP setup if you wish. Once you can etablish this you can enable security and get it working from there. At this time it is hard to say whether the nic, wpa, not seeing essid and so forth. To many variables at this time.

If worried turn off all other machines on network and enable a firewall on the linux machine. A basic firewall would block access to ports.

Left click the network manager icon in the upper applet bar. From here you can check and set your configuration and select which network ports are active. I'd try disabling the wired network and insuring the WLAN is enabled.

It works, the NIC is seen with the latest NDIS wrapper version. The Irony is that it does not work with my XP drivers, bot those of HP's. Ah well, at least it works. However it does not work in any encryption mode. Just the normal mode. I had to restrict the router to accepting one MAC address untill I get the security online. However it just refuses to connect. Any ideas?

So you can browse the internet without security enabled with current setup?
