hi Hans,

i had to reboot my router but i got my interface back running.
and i have good news
after that, im still using the buffersiz 2048 and this time i got 600mbps 
download /300 upload just like that.
these 2 things were not related i can see.

i guess thats it , looks like its solved.. i will keep monitoring here , but so 
far so good

thank you a lot as always
