Soeren,

i know this sounds extremely stupid.

But make sure the cards have a "relaxed" seat in the slots.

There is enough stuff out there, which does not even stay an antenna
connector change at run time. It is not even related to the price of the
"housings", just missing precision in "can" art.

Just to have it said.
