I have installed openwrt-brcm47xx-2.6-squashfs.trx on ASUS WL 500 GP. I see from some other posts that wifi is not possible. I chose this build because there was a very useful article on how to connect a logitech quickCam Orbit webcam to ASUS router. webcam works fine but I cant see the wifi. when I do wifi dect > wireless .. i see blank contents in the wireless file. I am stuck in woods. Can someone please advice. I am willing to revert back to 2.4 version if there is a way to configure the webcam.

Thanks in advance.

from http://downloads.openwrt.org/kamikaze/release.txt :

brcm47xx-2.6 - Netgear WGT634U, Broadcom Devices without Broadcom wifi
(you can use this instead of brcm-2.4 but wifi won't work)

asus wl-550gp seems to have broadcom wifi. so using 2.6 renders wifi useless on these devices.

It actually works. I right now have it working in client mode, with WPA encryption, works fine so far. There seem to be some range problems, but having a line of sight to the ap i haven't experimented much there.
edit: oh, using kmod-b43 by the way

But you haven't tried access point mode, have you? I guess working ap with WPA and without memory leaks and dissociatons is yet to be seen...

This is great news. You must be the first one to get the wifi running with the 2.6 kernel.

If you get a chance, can you please post the install steps? did you install kmod-b43 using "ipkg install kmod-b43" or is kmod-b43 in a different build. I will try this command tonight.

Thank you.

I believe many have run Broadcom wifi with the 2.6 kernel, but not without serious instability caused by "memory leaks and dissociations." That's the unsolved problem.

have anybody knows if this b43 driver works with bcm5354 chip used by my Asus wl520gu?

Oops, I must have been a little ambiguous here... I have never tried running 2.6 kernel on my Asus WL500gP. I simply deduced that AP mode (my main demand against a soho router) would not work with 2.6, based on forum posts and searching, so I use 2.4 (as instructed by the wiki btw). As for my remark on memory leaks and dissociations: that actually applies for kernel 2.4. As I pointed it out in a thread called something like 'Association&dissociaton memory leak problem', I'm experiencing hiccups in wifi connectivity - and I was informed that I was not the only one, since this was likely a problem in the Broadcom proprietary binary driver. Sorry if I was unclear in post #4.

yes, i did use the 2.6 kernel. I'm not the first one i guess, http://forum.openwrt.org/viewtopic.php?id=13286 (the one also linked by exactt) contained some help, and some people there also used it as an ap, afaik). The steps where just installing the kmod-b43 (latest sources) and its dependencies and then editing some config files to set it up in client mode. for wpa i also installed wpa_supplicant. right now i can use it only at the univerity, so i've never run it for more than a few ours, so memory leaks are possible.

very cool.. did you use it on Wl500Gp w/ broadcom chip? thanks.

Exilant:
Congratulations that you have succeded to get the 2.6 kernel so work on a standard WL500gP with Broadcom wifi chipset! I should like to have the same functionality as you have, client mode with WPA support. Can you post your image for me to use?

t
I have built using the latest source in 2.6 .. can you share the info about the steps to configure b43? ipkg list shows kmod-b43 - 2.6.23.16-brcm47xx-1 so it is installed.. the wireless file in /etc/config folder looks like this

config wifi-device wlan0
option type mac80211
option channel 5

# REMOVE THIS LINE TO ENABLE WIFI:
# option disabled 1

config wifi-iface
option device wlan0
option network lan
option mode ap
option ssid OpenWrt
option encryption none
i don't see the OpenWrt as available wireless network .. is there anything else to configure.. thanks

i don't know, i only need and use client mode so far. right now i'm using it to connect to a wlan
my config is:

# cat /etc/config/wireless
config wifi-device      wlan0
        option type     mac80211
        option disabled 0
config wifi-iface
        option network  wan
        option device   wlan0
        option mode     sta
        option ssid     wlan@thenet
        option hidden   0

# cat /etc/config/network

#### VLAN configuration
config switch eth0
        option vlan0    "1 2 3 4 5*"
        option vlan1    "0 5"


#### Loopback configuration
config interface loopback
        option ifname   "lo"
        option proto    static
        option ipaddr   127.0.0.1
        option netmask  255.0.0.0


#### LAN configuration
config interface lan
        option type     bridge
        option ifname   "eth0.0"
        option proto    static
        option ipaddr   192.168.1.1
        option netmask  255.255.255.0


#### WAN configuration
config interface        wan
        option ifname   "eth0.1"
        option proto    dhcp

## WLAN ###
config interface        wlan0
        option ifname   "wlan0"
        option proto    dhc

and a wpa_supplicant.conf, and an oversimplified startup script for wpa_supplicant(if someone knows the right way to do this, please tell me):

# cat /etc/init.d/myscript

#!/bin/sh /etc/rc.common
START=75
STOP=10

start() {
        wpa_supplicant -iwlan0 -c/etc/wpa_supplicant.conf &
        /root/dyndns.sh
}

stop() {
        echo going down...
}

so, really nothing special. Maybe you need hostapd even for an open ap, i don't know.

I've just flashed wl-500gp with r12903. The AP mode seems still not working. Even though I set it in AP mode it works as client...

my config:

config wifi-device  wlan0
        option type     mac80211
        option channel  5

        # REMOVE THIS LINE TO ENABLE WIFI:
        option disabled 0

config wifi-iface
        option device   wlan0
        option network  lan
        option mode     ap
        option ssid     OpenWrt
        option encryption none

Yeah, same on a WRT54GL v1.1. It worked some time ago but now it's broken again, even in the release...

If you have a Premium v1 replace the wireless card with a Madwifi compatible

Well, thatâ€™s a shame. Iâ€™m building svn r12947 right now, and was under the wishful impression that things would work now.

I donâ€™t need encryption, my neighbors are free to use it, but I need a WDS link to my colleague.
From your config, Marek, it seems that not even basic no frills AP mode works with b43. Is this correct? And are you positive that this is the /supposedly/ correct config?

I there!

I have a WL-500GP V2. Right now I'm using kernel 2.4. Everything works great but I can't connect to wpa protected networks using the wpa-supplicant.
The last time I tried kernel 2.6, everything works except the wifi and when I installed the kmod-b43... pufff the router doesn't boot anymore :S

My question is; there is any patch that we can apply to get the wifi working on 500GPV2?
Thanks

Hi,

about two weeks ago was the last time I compiled kamikaze. the b43 wifi works, but indeed
there are many connection losses when it's used in AP-mode.

towolf, my config is the most simple AP config we can use.
The problem seems to be related to mac80211, not to b43 only. It is because yesterday I replaced standard broadcom wifi card from wl-500gp with atheros based and installed ath5k driver wchich usues mac80211 like b43. The efect was the same - interface is created but in Managed (STA) mode, not Master (AP). Scanning with airodump from other computer confirmed that card is in station mode because it is probing network with definied SSID...
I tried manually switch to Master mode with 'iwconfig wlan0 mode Master' without success..

The discussion might have continued from here.
