Hi,

I am very new to OpenWrt and this is the first time I am trying to put OpenWrt on my WNR854T router, I have replaced the mini-pci card with an Atheros wireless card which should be supported by OpenWrt, but I am not able to enable wireless for some reason.

The image I am using is:
openwrt-wnr854t-squashfs-webupgrade.img (Oct 28, 2009)

I can see this message from serial when the router boots up:

Registered led device: ath9k-phy0::radio
Registered led device: ath9k-phy0::assoc
Registered led device: ath9k-phy0::tx
Registered led device: ath9k-phy0::rx
phy0: Atheros AR5416 MAC/BB Rev:2 AR5133 RF Rev:81: mem=0xc2a00000, irq=36

Here is my /etc/config/wireless file:

config 'wifi-device' 'wifi0'
        option 'type' 'atheros'
        option 'macaddr' '00:07:c1:31:05:30'
        option 'country' ''
        option 'hwmode' ''
        option 'channel' '0'
        option 'maxassoc' ''
        option 'distance' '20'
        option 'diversity' ''
        option 'txantenna' ''
        option 'rxantenna' ''
        option 'disabled' '0'
        option 'antenna' ''

config 'wifi-iface'
        option 'device' 'wifi0'
        option 'network' 'lan'
        option 'mode' 'ap'
        option 'ssid' 'MYSSID'
        option 'bssid' ''
        option 'encryption' 'psk2'
        option 'server' ''
        option 'port' ''
        option 'hidden' '0'
        option 'isolate' '0'
        option 'txpower' ''
        option 'bgscan' '0'
        option 'frag' ''
        option 'rts' ''
        option 'wds' '0'
        option 'key' 'MYKEY'
        option 'key1' ''
        option 'key2' ''
        option 'key3' ''
        option 'key4' ''
        option '80211h' ''
        option 'compression' ''
        option 'bursting' ''
        option 'ff' ''

But when I tried to turn wireless on:

wifi up

I got:

wifi0(atheros): Interface type not supported
wifi0(atheros): Interface type not supported

So, what else do I need to do to enable wireless on my router.

Thanks in advance.

I guess that was because the /lib/wifi/atheros.sh is missing, where can I find the script then? Thanks.

Changed wifi type to "mac80211" and changed "hwmode" to "11ng", wifi is now working (even the wireless LED is off), next step will be enable HT-40 mode.

looks like 5ghz N is not supported by the current hostapd?

driver shows the wireless card support dual bands:

        option 'ht_capab' '[HT40-][SHORT-GI-40][DSSS_CCK-40]'
        option 'diversity' '1'

It complains:

Line 4: unknown hw_mode 'n'
1 errors found in configuration file '/var/run/hostapd-wlan0.conf'

So, how do I enable N-only? and how do I enable 5ghz N-only?

Would anybody tell me how to enable Wireless N only mode and how to enable 5ghz N?

Thanks!

The discussion might have continued from here.
