Yes, it's a philosophical thing. By flashing the BIOS I address the
error. By changing the wireles EEPROM I counter the error with another

While wpi is the first one in my care that does not work at all, all
other Intel brand wireless devices in my use have proven to be
at least unreliable.

So what if they work reliable one day. The Atheros I got is reliable,
Not in a far fetched future that might never actually come to be.
