Hi Hans

just a heads up, it worked, tested a thousand times and the problem does not 
occur anylonger after i changed the constant to 2048

but upload speed was affcted a little i believe.
insted of 600/300 of internet speed , im having 600/90

but thats fine, way better now.

should this bug be in bugzilla for this ure driver as well wehave for axge?

thanks
