serious problem with wi(4) (D-Link DWL-650)

Hello,

I have timeout problems with the D-Link DWL-650 every time I try to
transmit big files (> 500 KB, for example): the transmission gets hanged
after 200-300 KB have been transferred (the exact point varies). It also
sometimes happens when when doing a ping flood (ping -s 1400 -f). However,
data reception works just fine, including promiscuous mode.

The system is running 4.6-RELEASE. The card is operating in infrastructure
mode, and it gets correctly associated to a base station. WEP-128 bit is
enabled.

These are the relevant kernel messages:

   >>> and so on... <<<

The system enters an quasi-frozen state, until I remove the card: about
15-20 seconds later the card extraction is detected and the system
resumes its normal operation.

I tried to set hw.pcic.intr_path=1 to no avail. Other PCMCIA cards work
just fine (the machine is a Dell Inspiron 3700).

Any ideas?

Cheers,
JMA
