ubunty wifi: cant acquire IP address

Running Ubuntu 8.04 (Hardy Heron) on a desktop PC using (or trying to) a
Linksys WMP54G PCI wifi card (that uses a Broadcom BCM4306 chipset.)
Trying to connect to a Netgear DG834 adsl router.
It works using windows xp just fine.
It doesn't in Ubuntu no matter what I seem to do, althugh it's fine using a
wired connection.

Tried latest "restricted" Broadcom drivers in Ubuntu and even compiled them
myself to check.

lspci gives:
(cut version)
00:0f.0 Network controller: Broadcom Corporation BCM4306 802.11b/g Wireless
LAN Controller (rev 03)
00:11.0 Ethernet controller: Realtek Semiconductor Co., Ltd.
RTL-8139/8139C/8139C+ (rev 10)
From which I assume the card and drivers are okay????

But using wifi radar or wicd I can't establish an ip address.

Now iwconfig says there is a card there but states encrypt is off , even
though I have setup WEP with a password (to avoid WPA added complications at
this time.)
Also it seems to say RX is invalid??? Dont know what that means.

Here it is:
IEEE 802.11g ESSID:"sally000"
Mode:Managed Frequency:2.412 GHz Access Point: Not-Associated
Tx-Power=27 dBm
Retry min limit:7 RTS thrff Fragment thr=2346 B
Encryption keyff
Link Quality:0 Signal level:0 Noise level:0
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0

Also the PC is next to the wireless router (2 feet away) so is the signal
level rather low? But it does work with XP as I said above..

Can ping the router using wired connection but not with wireless. The PC
sees the MAC address of the router but the router doesn't see the wireless
card.

Have another wifi device (a usb asustek which uses rt73 drivers and although
it connects intially it then disconnects and also seems to stop the wired
connection to my other pc running xp, so I don't feel it's a viable option.

Totally frustrated and out of ideas. All help appreciated.

Cheers
Dave

Nope. They probably are OK, but you tell that by the fact the they
have brought up an interface (see later). The above is taken from a
table and just identifies the hardware.

What happens if you try to let Ubuntu do it all itself? I.e. can't
the network manager get you connected?

Rx is receive (as opposed to Tx -- transmit) so...

this says there have been 0 receive errors (none due to invalid nwid,
none due to invalid frag, etc).

Yes. It looks like either the driver does not report the signal
strength (unlikely) or it is not really working. What does dmsg have
to say about the driver. For example, I need the ipw2200 driver and I
get:

$ dmesg | grep ipw
[ 7.682082] ipw2200: Intel(R) PRO/Wireless 2200/2915 Network Driver, 1.2.2kmprq
[ 7.682088] ipw2200: Copyright(c) 2003-2006 Intel Corporation
[ 7.684676] ipw2200: Detected Intel PRO/Wireless 2200BG Network Connection
[ 5.223188] ipw2200: Detected geography ZZD (13 802.11bg channels, 0 802.11a channels)

I do all this sort of stuff with WEP off to start with. From the
bottom up you need:

- The driver to find some hardware it understands.
- The hardware to associate with the right AP
- The interface to be given an address (often just by using DHCP).
- The routing tables to be correctly set up
- The right DNS server.

If the hardware is working, I'd expect

$ iwlist scan

to show your AP. Does it?

What does the output of a 'dmesg' command have to say about your
BCM4306? The lspci output only shows that the card is plugged in. Most
of the useful stuff is in the system logs that you can access from
dmesg (for the current boot) or from /var/log/messages (for the
current boot and before).

I guess that you will see messages about missing firmware. You did
turn bcm43xx debugging on, or didn't you?

Ben,
Really appreciate your help.
Answering your questions:
1.Just using net manager didn't help. Same "cant establish an IP" issue.
2.Yes I knew what rx and tx stand for but wasn't sure what this all meant. I
guess no errors is because there isn't any comunication going on.
3.Tried dmesg | grep ipw with and without sudo but got no response, just
threw me back to the prompt.
4.Have tried with and without WEP but no difference.
5.iwlist scan gives:
--------------------
lo Interface doesn't support scanning.

eth0 Interface doesn't support scanning.

wmaster0 Interface doesn't support scanning.

wlan0 Scan completed :
Cell 01 - Address: 00:18:4D:49:2C:0E

---------------------------
My wireless net SSID is sally000. The unprotected "zoom" is next door. I
have told them about this before!! They are lucky it's me that's their
neighbour! and not someone less scrupulous.!
So iwlist doesn't seem to show my AP.

I even reseated the PCI card, rebooted and did this all again.
Then did a sudo iwconfig which gave:
---------
lo no wireless extensions.

eth0 no wireless extensions.

wmaster0 no wireless extensions.

wlan0 IEEE 802.11g ESSID:"sally000"
Mode:Managed Frequency:2.432 GHz Access Point: 00:18:4D:49:2C:0E
Tx-Power=27 dBm

Encryption key:A7C3-E7FF-5E
Link Quality:0 Signal level:0 Noise level:0
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0
--------

Note encryption now seems to be recognised. This is what I am uneasy about.
How things seems to change back and forth. Flaky.


In addition: I tried to connect using a static IP. Using wifi radar it said
it had connected to the IP I had set up but when I disconnected the wired
LAN cable I found the connection didn't work.
As an aside must I unplug the network cable if I try to use wireless?

Does this help you to help me. Just ask if you need more clues.
Thanks again
Dave

Think I was being stupid earlier on when I said didn't get anything from
dmesg | grep iwp as I think that was your particular wireless board.
Mine uses a broadcom 4306 and b43-fwcutter so i got a response when i used
dmesg | grep b43
This is it:

--------------------------
[ 54.575135] b43-phy0: Broadcom 4306 WLAN found
[ 70.172030] input: b43-phy0 as /devices/virtual/input/input6
[ 72.206158] Registered led device: b43-phy0:tx
[ 72.207040] Registered led device: b43-phy0:rx
[ 72.207678] Registered led device: b43-phy0:radio
[ 77.695944] input: b43-phy0 as /devices/virtual/input/input7
[ 80.038241] Registered led device: b43-phy0:tx
[ 80.038761] Registered led device: b43-phy0:rx
[ 80.039016] Registered led device: b43-phy0:radio
------------------

Doesn't say anything to me but you experts will no doubt hopefully see the
light.
Cheers

Hi Larry,

dmsg gives me 10 feet of stuff but I have narrowed it down by dmsg | grep
b43 to get

-------
[ 54.575135] b43-phy0: Broadcom 4306 WLAN found
[ 70.172030] input: b43-phy0 as /devices/virtual/input/input6
[ 72.206158] Registered led device: b43-phy0:tx

[ 80.038761] Registered led device: b43-phy0:rx
[ 80.039016] Registered led device: b43-phy0:radio

------------------
Does this help?
If you really want the full output I can send it.

What is bcm43xx debugging????
I am not using the bcm43xx-fwcutter but the newer b4-fwcutter as per the
recent threads I have read. Also
http://linuxwireless.sipsolutions.ne...rs/Drivers/b43
Is this wrong?
Is there life after wireless?
Cheers

As you are using the b43 driver, please select the debug option for
both b43 and the Silicon Sonics driver. No, I don't need the full
dmesg output.

Yes using b43 as thats what
http://linuxwireless.sipsolutions.ne...rs/Drivers/b43 and soem googled
outputs have recommende and tht's what is the default on Ubuntu 8.04.
But still don't underatydnm what you mean by debug option. Sory to be thinck
but no idea what this and where.
Also not sure why you say to use silicon sonics drivers. Its a broadcom chip
so using broadcom firmware. Have I lost the plot? Sorry to be a noob.
Cheers

It's a silly question but your AP is on Ch 5 isn't it? Yes, I know it
works in doze, but maye be doze quietly overides defaults or ubunty
does...

> Quality=81/100 Signal level=-45 dBm Noise level=-68 dBm


It appears to be seeing something but is it your AP?

It may seem flaky and firm up when you get a feel for what is going
on. I am in the dark here as I don't know this driver but all the
above looks good except for the signal level. I found this:

http://linuxwireless.sipsolutions.ne...rivers/b43/faq

that says:

If iwconfig shows

* Link Quality:0 Signal level:0

then you may have wireless disabled in the BIOS. Check for things like
"Wireless : Application Control".

Is that a possibility?
