wireless connection with fwcutter bcm4306 very slow

[Gerri]

Binary package hint: bcm43xx-fwcutter

Same problem as leeard reports just different hardware software:

Ubuntu 7.10

~$ sudo lspci -v | grep BCM
02:00.0 Ethernet controller: Broadcom Corporation BCM4401 100Base-T (rev 01)
02:03.0 Network controller: Broadcom Corporation BCM4306 802.11b/g Wireless LAN Controller (rev 02)

[Gerri (gerrith)]

Argh, hit the sent-button too fast:

Well, connection to AP without problems. Though, connection very slow (~30kb/s).
I disabled encryption but problem persists.
In case I forgot some information, please let me know.
Thanks

Gerri

It may not be the problem (driver tends to report not very accurate stats) but here a -65dBM noise level is very high! Usually on my different cards, I have -90 and below.

Have you tried on different location / access point?

[Gerri (gerrith)]

The noiselevel I cited is the result of a quite remote position from the AP. Tried right next to the AP (noise level -93dBM) and also different APs, same problem.

I switched to ndiswrapper yesterday, e voilá: WLAN at fullspeed under the same conditions as with fwcutter...

[Nicolas Deschildre (ndeschildre)]

Ok since on the same conditions you noticed such a difference of speed with ndiswrapper and the bcm43xxx driver, I think the bug can be confirmed.

But before that could you give me the output of lspci -nn concerning the card please? And the dmesg output if you see anything unusual?

Thanks!

[Gerri (gerrith)]

lspci -nn:

02:03.0 Network controller [0280]: Broadcom Corporation BCM4306 802.11b/g Wireless LAN Controller [14e4:4320] (rev 02)

dmesg with ndiswrapper loaded results in nothing suspicious.
I will deliver the dmesg with fwcutter loaded the next days, if needed (I assume it is, pls let me know if not.. ;) ).

Thanks so far
Gerrit

[Nicolas Deschildre (ndeschildre)]

Yes I guess it may be useful to the devs!

I just found you are far from the only one with this problem. In fact a bug with the very same title exists already, and had some traffic. As a consequence, I mark this bug as duplicate.

Thanks for the bugreport!

[Gerri (gerrith)]

Sure, I read that bug report, just thougt different software and another Broadcom -chip was worth another bug.. ;)

Anyways, dmesg of fwcutter loaded follows the next days, here is lspci -v:

02:03.0 Network controller: Broadcom Corporation BCM4306 802.11b/g Wireless LAN Controller (rev 02)
        Subsystem: Dell TrueMobile 1300 WLAN Mini-PCI Card
        Flags: bus master, fast devsel, latency 32, IRQ 5
        Memory at faff6000 (32-bit, non-prefetchable) [size=8K]
        Capabilities: [40] Power Management version 2

Good luck with the bug and thanks a lot for fwcutter! First time I was able to enable monitor mode with a broadcom wlan-card...

[Gerri (gerrith)]

Find attached the dmesg output with fwcutter.

[Gerri (gerrith)]

problem is still present: downloads not faster or around 34 KB/s. Also, downloads seem to stuck from time to time. Hope you can find a solution soon? If you need any more information: I will keep the fwcutter installed for some time now and go online with a wired connection. Thanks for your efforts
