Hi,

Hope all is Well. I have a question. I have a windows 7 Machine (64 bit) (Home Premium) I have 16 (Gigs) Memory An intel i7 (3rd Gen) I have a gigabyte z77x ud5h Motherboard (rev 1.0) The problem is I have 2 ethernet controllers in my system one is Qualcomm Atheros AR8151 PCI-E Gigabit Ethernet Controller (NDIS 6.20) and the other is Intel(R) 82579V Gigabit Network Connection Now I have them both Bridged. Meaning that you highlight both adapters and you hit bridge connections And it creates a network bridge Icon mac mini port bridge. Now when I go into the advanced properties of both cards. And I go to the speed and duplex setting I can't set it for gigabyte speed. I can't set it for 1.0 gbps full duplex. I can set one of the two cards for this setting, doesn't matter which one but I can't set both If I set one then try to set the other for the same setting it says network cable is unplugged. And it shows a red x on the icon of that ethernet controller. How do I get both ethernet controllers to use gigabyte speed at the same time. My router is a WRT160N (V3) Its a Linksys or cisco. And it is a gigabyte router. There is no setting to set the link speed from directly in the router.


Thanks so Much!

The PC may be saving you from a network loop by shutting a port down. Since from you description you have plugged both cables into 2 lan ports on the router. The router ports are a switch or bridge and you have bridged the ports on your PC. What happens is broadcast traffic is sent to all ports except the one it was received. So the traffic goes round and round and eventually you will get so much traffic nothing else can pass.

Many switches run spanning tree to prevent this but cheap switches and routers do not support it. The pc though may.

In any case you are wasting your time. You can not combine the ports without a special switch and special configuration on the pc. Even after that it it does not actually use both...

Even after that it it does not actually use both connection equally it is designed for many machines to talk to a large server running bonded ports like this. It will assign different machines to different ports no single machine can use both gig ports.
