loss wireless internet once connect to a wire router?

[Smilingrock764]

Hi,
I have 2 PC. One connect to internet through wireless (let call it PC_internet) and the other having no wireless and I want to connect both of them through a wire router just for the purpose of exchanging file between them. (I dont want the second PC get connect to internet). That wire router has no internet access.

At first, everything goes as I planed but then I play around and now the problem is that:

- If I enable the "Realtak PCIe GBE Family Controller" which should be the network card of the PC-internet, that PC cannot connect to internet. The internet map is: PC-internet --> wireless router --> Gateway (which I have no idea) --> internet.

- If I disable this above network card, now this PC-internet have internet again! the map now is: PC-internet --> wireless router --> internet.

My guess is that the Gateway is the wire router I use to connect the 2 PC and some how, I change the order of the network so that the PC "go to this wire router" for internet, instead of connect directly to the wireless.

Could anyone help me to correct that problem?

Thank you so much.

But at the beginning when I connect to the wire-router, they can communicate and the PC-internet still have the wireless internet. So it doesn't look like that PC choose the wire over the wireless by default.

The wireless PC defaults to the wired-LAN connection when connected. The PC cannot connect to multiple networks at the same time so it picks one in a pre-determined order. You would need to bridge the two connections and make sure settings such as DHCP range, and gateway addresses are not conflicting. This would cause your computer to effectively use both networks as one. This would also, however, cause the wired network to have internet access.
