I am having a hard time getting two SR9s to work together. I have two Soekris
boxes with an SR9 in each side by side (literally 5 inches away from each
other) and I keep seeing "status: no carrier" on the client side:

root_at_bsdap# ifconfig ath0
ath0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        inet 192.168.0.2 netmask 0xffffff00 broadcast 192.168.0.255
        ether 00:15:6d:90:03:b4
        media: IEEE8802.11 Wireless Ethernet autoselect mode 11g
        status: no carrier
        ssid test channel 33
        authmode OPEN privacy OFF txpowmax 33 bmiss 7 burst bintval 100

If I let it scan and enable debugging, it will scan through all the available
channels (I did set countrycode to 843 in order to use the 900Mhz band) and
come up with nothing:

root_at_bsdap# wlandebug -i ath0 +scan
net.wlan.0.debug: 0x0 => 0x200000<scan>
root_at_bsdap# ath0: ieee80211_cancel_scan: end passive scan
ath0: notify scan done
ath0: ieee80211_end_scan: no scan candidate
ieee80211_reset_scan: scan set: 3, 4, 13, 14, 16, 23, 24, 26, 33, 34 start chan 4

ath0: ieee80211_cancel_scan: end passive scan

ath0: ieee80211_end_scan: no scan candidate

This doesn't look right to me:

root_at_bsdap# athstats
0M current transmit rate
-80 rx noise floor

I am using the same image (read-only on a Compact Flash card) on both client
and host sides:

..and host side:

The host side interface looks like this:

Enabling any kind of debugging on the host side produces no output. 

I must be missing something here because if I put two regular a/b/g cards (CM9
and Senao  NMP-8602+) into these boxes, then I have no problems connecting
them together with the same drivers (0.9.30.7 hal on 7.0-CURRENT). I even
tried hooking up a pigtail to each card since I don't have any 900mhz antennas
but to no avail. However, the a/b/g cards work without pigtail/antenna. The
SR9s have been recently tested with latest madwifi-ng under Linux so it's
unlikely this is a hardware problem but not completely impossible. I did try
switching the cards around but that didn't help either. 

Looking for some help here on how to troubleshoot this....

Thanks.
