Hello, sorry for posting this in a DEV list, but I tried elsewhere and
people are generally kind, but unhelpfull. I am NOT a kernel
programer, so I will impose on the list´s good will somewhat ;)
I have a Laptop witch uses the Realtek rtl8187b chip in a USB internal
conection.
The chip WORKS in kernel Debian 2.6.32-3 , but is has an odd behavior:
It works, connects and gives me ADSL speed as long as I am no more
than 3 meters from the router. Beyond that I get a "wrong password"
message in NetworkManager or Wicd (tried them both with similar
results)
The bug is reproductible in Debian 2.6.32 Kernels i386 and amd64 and
in Ubuntu 9.10 64bit too, I had it working successfully on a Mandriva
2010.0 with the -12 kernel, but did not test it to it´s fullest. If
needed I can do this.
logs:
This is when it works:

eth0 no wireless extensions.
Here are some observations:
1) eth0 keeps auto-negotiating forever, as long as the box is powered
it still tries to negotiate even though no cable is connected.
2) see that when the deect occurs the probe was SUCCESSFULL the
authentication that failed
Anybody got a clue?
Thanks in advance
