Hello,

I run the above mentioned combination for W-LAN, at home with
WEP and in the office with WPA-PSK. From time to time, very seldom,
I encounter damaged TCP traffic, for example:

- a mail reaches the next SMTP hop with garbage in the body;
- fetching a page with HTTP brings up a message about 'bad HTTP
  request' with some random chars;
- on 'scp' traffic it stops with a message about 'bad MAC addr';

Is this a known issue with the iwi driver/firmware? How is it
possible that higher layer (TCP) does not detect this problem
in the TCP-checksum stored in the header?

Thx in advance for any hint

	matthias
