Hello

We have some Ralink RT3071 devices (Delock 88524) and we need to
configure them either as Ad-Hoc or Access Point. In both cases I get a
connection and seems to work for transferring small files (1MByte).
Whenever I start sending more (500Mbytes) then it starts, holds for
some time (3 seconds maybe) and then it drops. After that, the
connection is useless and things need to be restarted. We have a
laptop with an Intel 3945ABG which has no problems with the connection
and the big file, but all other devices (ralink 8188cu chipsets and
others) stop working when doing the big file transfer. The file
transfer is done via samba server with a windows xp machine as
counterpart. But that is not it as http transfer also stalls
everything.

I am using the compat-wireless driver from the 10th of March, cross
compiled against kernel 2.6.24.

I am using the firmware that can be downloaded from the Ralink website
V22 (any newer?)

For IBSS, I use iwconfig entirely and setup an uprotected connection
with a fixed ip address on both sides.

I do have a small issue on the 2.6.24 system due to cross compilation
(as my system was not pure 2.6.24) when registering the device....
dmesg shows:

#-----------------------------------------------------

But I don't think this is the issue as i have the same problem in
other systems that do not present these warnings/errors.

For the Access Point, I use HostAPD and DHCP

For HostAPD, i use:

My dhcp.conf looks like
#-----------------------------------------------------
option domain-name "MyDomain";
option subnet-mask 255.255.255.0;
option broadcast-address 192.168.111.255;

default-lease-time 600;
max-lease-time 7200;
authoritative;
log-facility local7;

subnet 192.168.111.0 netmask 255.255.255.0 {
  range 192.168.111.1 192.168.111.254;
  option ip-forwarding off;
  default-lease-time 86400;
  max-lease-time 86400;
  option subnet-mask 255.255.255.0;
  option broadcast-address 192.168.111.255;
  authoritative;
}
#-----------------------------------------------------

My hostapd.conf looks like
#-----------------------------------------------------
interface=wlan5
driver=nl80211
ssid=rt3070ap_g2
channel=2
hw_mode=g
max_num_sta=1
#-----------------------------------------------------

HostAPD is correctly configured and connections are possible. DHCP
works as well as the devices get their IP address. HostAPD does not
show any irregularities, and any other log files do not give any
hints.

iwconfig shows

#-----------------------------------------------------

But as said, I don't think hostapd is the problem, I suppose it has to
do with the driver or the firmware.

If someone has the updated firmware, please send it to me, i'd appreciate it.

Some other info:

When this big file transfer fails, my ssh connections break.
When configured as ad-hoc mode, it won't allow to turn off power
savings (iwconfig wlan5 power off <-- fails)

What else can I do? How can I get more debug information about what's happening?

Best regards,
