Hi,

I did some new tests to see what's my transmission problems with
rtl8187b. I can associate and can send pings (and even to connect
through ssh with other hosts) but i can't transmit "big" files. But
at first mail I didn't know how big must be a "big" file.

I tested with 64, 128, 256, 512, 1024 and 2048 bytes files. From 64 to
512 I always can transmit the file. 1024 sometimes hangs and 2048
always hangs. All files can be transmitted using rt73usb wireless.

I put the tcpdump output of those tests in:

http://www.slackware.com/~piterpunk/transmittests/

The 512-byte file dump is almost equal for both wireless cards.
2048-byte is very different. All logs are scp from my machine to
slackware.com. But the same happens sending mail (but not receiving),
uploading ftp files, doing scp to other machines, etc...

I'll be very happy to provide any extra information or do additional
tests with the cards to help the problem diagnostics. Changing the
rate didn't have any influence in test results. I have an iwl3945 that
works fine, too.

Thanks in advance!
