>Description:
I've got an Eminent Wireless USB (EM3035) device with the Ralink chipset
ural0: Ralink 802.11g WLAN, rev 2.00/0.01, addr 2
ural0: MAC/BBP RT2570 (rev 0x03), RF RT2526
ural0: Ethernet address: 00:06:f4:0b:d6:0e
ural0: if_start running deferred for Giant
When in hostap mode, the encryption fails. I tried both WEP (ifconfig) and WPA (hostapd).
When in clientmode, encryption is OK. I tried the device with OpenBSD which works OK with hostap+wep, so the card seems to be ok.
configuration:
ifconfig_ural0="ssid home wepkey 0x1234567890 weptxkey 1 wepmode on mediaopt hostap up"
Tcpdump says:
17:16:55.609147 IP 0.0.0.0.68 > 255.255.255.255.67: BOOTP/DHCP, Request from 00:40:96:58:24:d3, length: 300
17:16:55.609168 IP truncated-ip - 24209 bytes missing! 175.8.224.204 > 86.30.246.56: ip-proto-216
I can see incoming traffic, so I used the correct key.
But outgoing traffic seems to be broken.
>How-To-Repeat:
put the ural-device in hostap mode and try to use encryption. tcpdump the traffic to see that something is broken.
