>Description:
rum driver not working with several (all I found) usb wireless cards in hostap mode. At first sight  client station is connected and ping is ok. After putting some load at wireless link ( opening big web page or stating download file and client machine) link hangs. Sometimes dhcp does not work, but if I set manual IP address traffic comes for a little time and hangs. Using tcpdump in most case gives me following output:
[root at nomad ~]# tcpdump -i wlan0 -n
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on wlan0, link-type EN10MB (Ethernet), capture size 96 bytes

[root at nomad ~]# tcpdump -i wlan0 -n
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on wlan0, link-type EN10MB (Ethernet), capture size 96 bytes

Sometimes I see traffic from client machine only (arp requests)

May be it is connected with some broadcasting problem.

If anybody needs I can provide ssh access to machine - it is test setup, I want to make 3G/Wireless router for my car :)

The machine is old P3 (IBM Thinkpad T22), but I have tested on few other machines with exatcly the same result.

I use this scrpt to create wlan0:
[root at nomad ~]# cat /root/ifcreate
#!/usr/local/bin/bash

wifi="wlan0"
wdev="rum0"
wauth="open"
loc="indoor"

echo creaing $wifi

ifconfig $wifi down
ifconfig $wifi destroy

ifconfig $wifi create wlandev $wdev  wlanmode hostap authmode $wauth\
         ssid nomad country BG $loc
sleep 2
ifconfig wlan0  192.168.90.1/24 up

# wlandebug -i $wifi  +scan+auth+debug+assoc
/usr/local/etc/rc.d/isc-dhcpd restart
/etc/rc.d/named restart
pfctl -d
pfctl -f /etc/pf.conf
pfctl -e

ifconfig wlan0

outout from it:
[root at nomad ~]# /root/ifcreate
