here is a new driver for rtl8187L that compiles without errors in ubuntu
9.10, but it doesnt seem to be fully operational so maybe a patch could
fix this.

Dennis: That was my thought as well, that the error message is saying I
don't handle this chip. I did try blacklisting the r8187 driver, but
that accomplishes nothing as it appears that the rtl8187 driver has been

When you say it wiped out the older rtl8187 driver, that means the
find+grep command I mentioned above only shows one .ko file? (namely
r8187.ko or something like that?) Perhaps re-installing your linux

I have the same problem - very weak signal, sometimes breaks of

In Jaunty there is a driver which shows full (i.e. normal) signal.
