rum(4) is known to have bad rx signals, eg. it is not complete.
Also speed depends on reported tx rate; visible from ifconfig rum0 output.
old usb stack have its own limits ...

Re: rum0 performance < 1Mbps; ath0 reboots system

[Yury Michurin]

Hi Deceased,
I'm using Edimax
EW7318USG(RT2571)
with rum0, works fine for me after setting:
ifconfig_rum0="inet 10.0.0.1 netmask 255.255.255.0 ssid FreeBSD channel 7
media OFDM/54Mbps mode 11g mediaopt hostap"

when media was in "autoselect" i was getting poor rates < 500kb, after
setting the OFDM/54Mbps I'm getting ~2MB/s:
100% |*|98 MB2.04 MB/s00:00
ETA
226 File send OK.
103660722 bytes received in 00:48 (2.04 MB/s)
( transfer from the fbsd box to my laptop )

You can see available mediaopts with ifconfig -m rum0.

The only problem i'm currently having is after a while stations fail to
auth, which is resolved by restarting hostapd, I don't have a lead on that
one yet. ;\

If you interested, you can find my configs here:
http://www.blog.freebsd.co.il/2010/03/%D7%A9%D7%A8%D7%AA-freebsd-%D7%9B%D7%A0%D7%AA%D7%91-%D7%90%D7%9C%D7%97%D7%95%D7%98%D7%99/
( the text is in hebrew, but you'll get the idea, based on configs from:
http://www.howtoforge.com/setting_up_a_freebsd_wlan_access_point )

Best regards,
Yury.
