    I'm having similar problems with a PCMCIA orinoco wlan device. Works
    perfectly with various 2.4.X kernels but keeps (partially) dropping the
    connection with 2.6.X kernels. By partially, I mean connections are
    lost and pings report target hosts as unreachable but netstat -r reports
    make it look like the connection is still valid. Doing an ifup (without
    a preceding ifdown) seems to fix the problem.

    If more information would be helpful or testing is required don't
    hesitate to ask.
