It slows down and then after some minutes (15-30)  it  hang.  The  Nokia
show 3.5G and the "Connection Manager" an active connection but there is
ZERO traffic...

On the router I can not ping the Internet or do something else...


As you can see, it recoved the EXT3 since the kernel was crashed  and  I
had to reboot the router.  But there is a weird thing  with  it:  On  my
Laptop and my Intranet Server the kernel write @crash a message into the
logs, but on the Router is nothing...

Here the last outputs:
