Over the weekend my old motherboard crapped out, so I went and got a new one and cpu (Asus M3N78 pro). Everything works fine except my internet connection. It will run great and then all of a sudden it will disconnect, i'll get the "a network cable is unplugged" etc. This only seems to happen when I have my comp plugged directly into my modem, no disconnects when i plug into my router, but I don't usually use it bescause it literally cuts my speed by 50-75% (avg 20-25 mbps w/out...5-10 mbps with). Ive screwed with drivers, any settings I can think of, and can't fix this problem. Is it time to take the new board back and get a different one? I know the problem might go away if I just got a different router, but I'm wondering why this board doesn't like to be plugged directly into the modem, my old board (Asus A8N pro) never had a problem with it.
