I'm noting this here in case anyone is interested. After I
write this up, I'm going to start from scratch on the
configuration, and factory-reset the router.

<div>The 5GHz radio on my 3800 seems to be in a very odd state.
I'm not quire sure what state it's in, but it seems to be
only doing HT20 1x1. And in a fairly broken manner at that.</div>

That's interesting, since it's missing a few configuration options
and seems to be still using the US country code for the 5 GHz
interface. For what it's worth, my router's configuration looks
like this (with the MAC address changed to match your
configuration):<br>
<br>
config wifi-device 'radio1'<br>
option type 'mac80211'<br>
option channel '36'<br>
option hwmode '11na'<br>
option macaddr '28:c6:8e:bb:9a:49'<br>
list ht_capab 'SHORT-GI-40'<br>
list ht_capab 'TX-STBC'<br>
list ht_capab 'RX-STBC1'<br>
list ht_capab 'DSSS_CCK-40'<br>
option disabled '0'<br>
option txpower '17'<br>
option country 'GB'<br>
option htmode 'HT40+'<br>
<br>
I'm using channel 36 and HT40+ here at 17 dBm. This is also from a
UK-based router, so you'll probably want to change the country code
from GB to FR. I'm seeing about 270 Mb/s using Intel wireless
(4965AGN) and Windows 7 about 2.5 m away from the router with those
settings.<br>

My settings for the 2.4 GHz side (deliberately limited to HT20 to
avoid interference):<br>
<br>
config wifi-device 'radio0'<br>
option type 'mac80211'<br>
option hwmode '11ng'<br>
option macaddr '28:c6:8e:bb:9a:47'<br>
option htmode 'HT20'<br>
list ht_capab 'SHORT-GI-40'<br>
list ht_capab 'TX-STBC'<br>
list ht_capab 'RX-STBC1'<br>
list ht_capab 'DSSS_CCK-40'<br>
option disabled '0'<br>
option channel '1'<br>
option country 'GB'<br>
option txpower '20'<br>
<br>
This time I'm using channel 1 at 20 dBm. In both of these blocks
I'm leaving the distance option unspecified.<br>
<br>
Hope this helps a bit!<br>
