Question wifi performance (rum)

Hello everyone,

I'm currently using a Belkin USB network adapter on my old OpenBSD server laptop, on a USB 2.0 port:

rum0 at uhub3 port 2 "Belkin Belkin 54g USB Network Adapter" rev 2.00/0.01 addr 3
rum0: MAC/BBP RT2573 (rev 0x2573a), RF RT2528, address XX:XX:XX:XX:XX:XX

it is very stable; the issue is performance... I get ridiculously low transfer speeds, peaking at 150 KB/sec on NFS, Samba or SSH transfers (a quick test with netcat confirms it's the network link).
The same client and server, if using a wired fxp interface over powerlines, yield 4 MB/sec (but that connection drops out when other devices are activated - different story).

OpenBSD and the wireless AP are 5 meters away and have line of sight between them.
Latency between the two is good and consistent (2-4 ms, 0.0% packet loss)
ifconfig rum0:

rum0: flags=28843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST ,NOINET6> mtu 1500
lladdr XX:XX:XX:XX:XX:XX
priority: 4
groups: wlan egress
media: IEEE802.11 autoselect mode 11g (DS1 mode 11g)
status: active
ieee80211: nwid XXXXXX chan 6 bssid XX:XX:XX:XX:XX:XX 119dB wpakey <wpakey> wpaprotos wpa1,wpa2 wpaakms psk wpaciphers tkip,ccmp wpagroupcipher tkip 100dBm
inet 192.168.1.1 netmask 0xffffff00 broadcast 192.168.1.255

Clearly they can hear each other just fine (110+ dB)

The only thing I find odd is: 'DS1 mode 11g' - why would 'media autoselect' settle for the (I'm guessing) slowest setting?
'ifconfig rum0 media' lists a large number of options, from DS1 to OFDM54 (I can paste it here if you want)

I could try and force it to e.g. OFDM54 but I'm wary of losing connectivity as I'm remote to the machine, so I figured I'd ask for opinions or pointers before I try that.
Thank you for reading this post. Any ideas?
