Hi
I was posting into the rt200usb slow connection thread, but nobody seems to care about it. After many months the adapter began able to reach maximum speed of my line. But randmoly there are many invalid packets, those make the connection hanging on for seconds or minutes.
[code14su7g9x]wlan0 IEEE 802.11bg ESSID:"Alice-79217188"
Mode:Managed Frequency:2.412 GHz Access Point: 00:1D:6A:AE:A3:24
Bit Rate=54 Mb/s Tx-Power=20 dBm
Retry long limit:7 RTS thr:off Fragment thr:off
Power Management:on
Link Quality=68/70 Signal level=-42 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:52 Missed beacon:0
[/code14su7g9x]
This is really disturbing during streaming. Can I do something to debug the problem?

Is there any syslog output that might help? (dmesg)
If not perhaps you should try a kernel with ralink debug drivers.

If I recompile my kernel and make a dump with your tool, will somebody take a look at it, or is rt2500usb an abandoned project?

I'm here again, just to say that now I'm able to use at full capabilities my rt2500 chip based wi-fi usb dongle D
There was two problems
1) Regression of the driver to a situation that I myself had tracked almost a couple of years ago viewtopic.php?f=5&t=6043
Old iwconfig power off solution still work.
2) Second problem was the invalid misc. I changed transmission channel from my router settings, and now, after 8 hours of uptime, I have just 73 packets dropped (on channel 1, after few minutes I had many thousands errors of that kind)
The last seems not to be imputable to driver itself, but with ndiswrapper this problem doesn't exists (but various kernel panics if there is high upload), so in my ignorance I think rt2500usb driver is too much sensitive to disturbs.

Thanks anyway to everybody )
