When A Wifi Card Goes Bad?

[Omicron]

I am using a DLink WIFI card and it always worked great.

Lately I started using my Z again and when I put the card in it is recognized but it never connects, it just says "Network offline".

Sometimes I eject and re-insert the card and I get card unsupported (but ussually it recognizes it the first time,  this only happen of Eject/reinsert.

Oddly, on my C3200 it shows some activity in the WIFI monitor app, but while it shows the MAC address of the card for a while, the Mac Address will then suddenly disappear but the activity remains (signal strength/quality strong, but very little IO since it doesn't connect).  

Anyway, I am wondering if this indicates that the CF card is dying/dead or if there is some other tests I should try before giving up the ghost on this one?

It may well be possible to reflash the card firmware, it's certainly worth a try.
