posting here since there is a minute number of views in the networking section, and that i need to attempt to resolve this fairly soon.

ive been dealing with dropping connections like crazy for the last month. it takes me 15 minutes to connect to a freaking webpage. and now on my homebuilt computer, the connection has finally died and will not come back. ive unistalled, the drivers, reinstalled, everything. im on my moms computer right after giving up on this thing. im literaly shaking http://en.wikipedia.org/wiki/shake because this is so damn aggrivating. ive no clue what to do now, and seeing as ive totally lost it, im coming to you folks for help...

Im using the integrating ethernet adapter Marvell yukon 88E8053
Time Warner is my internet provider http://en.wikipedia.org/wiki/Internet_service_provider , my signal is strong, and ive replaced the modem and my router.

Well heres what you can do.
If you suspect a bad integrated NIC, buy a NIC card.
Put it into the computer and install the driver and see if that takes care of your problem.
If your motherboard is make by Asus and you send it in for replacement, may god have mercy on your soul.
I had a Asus where the southbridge raid function went bad, I sent it in for RMA in April of this year. After 4 bad boards 10 hours of phone calls and 25 emails, they finially sent me a new board. If this would have happened when I was sent the first board with the leaking caps on it, I would have been happy. But after fighting them for 6 months to finally get a working board, well I am not really jumping up and down for joy. I could have just put a $25 raid card into my system and kept on going.

Asus is off my buy list for anything they make.

Just booted into safe mode, opened a good 50 tabs and went to different websites. No connection drops what-so-ever..... was hoping it would be as easy as picking up a new NIC : ( im not good with software, so im gunna have to find some guidence to find the issue(s)
