Few week ago I bought a pcmcia LAN for my laptop.
Need to push in pull out every day because laptop can't put into the
carrying bag if don't pull out the LAN card.
Today I find that this LAN is not working, push in a wifi card and it
works, so must be the LAN card spoilt.

Could it be because I forgot to soft-disconnect before pulling out the
LAN card that spoilt it.
