Hi,
I have two rtl8187b cards. One built in my notebook and one external
USB wireless dongle from Encore. Both works with the rtl8187 driver
(thanks Herton! thanks Hin-Tak!) but i still have some problems.
I'm using 2.6.27-rc7 kernel and three problems are very common, but
intermittent:
1) I found my network when scan (iwlist wlan0 scan) but i can't
associate in the found network.
2) I associate in my network but i can't transmit anything.
3) I associate, can transmit but only "small" transmissions. Ping,
HTTP GET, POP commands... when i try to upload a file, send a
mail, etc... the connection stuck.
The three problems happens in both rtl8187b cards. I try with two
different access points to make sure the problem isn't AP related and
now i am using an rt73usb without problems.
Without encryption, the problem 2 isn't noticeable. I don't do
a lot of tests without encryption enabled, but i can do if you want.
That's one small example of problem 2:

If you have any specific tests or patches to apply I'll be
very happy to try and test them. If you need more information
to "see" the problem, only need to ask what information you
need.
Thanks!
