GA-EP45-UD3P Ethernet Problems

I have been using this board for some time. The one thing that i am very unhappy with is the Dual ethernet ports. I have installed all the latest drivers, but when i plug two cables into my machine, and set them as a conjoined connection in the diagnostics, i always get a BSOD.
I just finished a fresh install of vista 64 bit in raid0. Any tips on how to get this network issue solved would be greatly appreciated.

Thanks,
Joe

Welcome Newcomer!

Are you Bridging, Teaming, or Sharing the NICs? They are all different and all set-up differently. In most "home" environments the Teaming will not work {home routers do not support that feature} and Bridging is unnecessary in 99% of broadband situations. Therefore, Sharing (i.e. LAN Party) is about the only useful situation.

I would strongly recommend that you use the Realtek Ethernet Diagnostic Utility to set-up your NIC. I reviewed the Manual an there is a very good guide on page 84 for "Teaming." Teaming is good for redunancy and doubling the bandwidth, but keep in mind if there is not other PC/Server on your network it will be as fast as the slowest connection(s). Example, if your Router is 10/100 and another PC has a 1000 port the speed will be 100 -- if connecting to a PC with Team 1000 port then 200 will be the limit, etc. Further, if the purpose is to "improve" your internet connection then it will not; FIOS offers {50 Mbps X 0.125 = 6.25 MB/s} 6.25 is crazy slow compared to 100/1000/2000.

Further, my experience with Dual NIC is not to "Bridge" via Windows; Realtek & Intel have their own implementation which "may" explain your problem.
