i've been tackling this problem all day but didn't find a solution
after replacing my motherboard to an ASUS A8R-MVP and reformatting
i can't use utorrent (or rather download using utorrent) for more than 1 minute.
the internet connection is simply disconnected though the network itself or the router dont crash.
i tried limiting the number of global connections and connections per torrent to less than 100.
net.max_halfopen has been changed to 4. tcp/ip connection is set to 120 instead of 10.
i reinstalled the lan drivers of the marvell yukon and installed the ULi chipset driver (184.108.40.206a i think).
checked windows update untill there were no more critical updates.
didnt update the bios because the bios update tool on the asus site scares me...
this is frustrating.... any help appreciated
i also turned off upnp, dht and nat-pmp and restarted the router (fritz box wlan 7170) and modem (300hs i believe) and pc
