We are sure there is no power problems. The module can take much more 
than the maximum current required in the datasheet. The other point is : 
We have the same problem with the Accton Eval Board in an standard SDIO 
slot as with our custom board.

We already tried big pings It's working fine :
ping -s 2048 is working.

2048 bytes is maybe not enought.

The strange thing is : If we wget an ip with no machine, we have the 
same problem.
wget http://unused.ip.address

On a computer, this returns a timeout , on the target with ar6k, we have 
exactly the same log as if we used a valid address. This is the proof 
the problem is with sending the query, not receiving something too big.
