I don't follow. The DG834GT is a wireless router and you want to use another PC via wireless. Why would you want to use a DG834G?
I can only assume you want to plug the DG834G into the PC and use that as a wireless client bridge to connect to the GT's network. If that's the case then no, you cannot do it that way - you'll need either an ethernet wireless bridge, a PCI wireless card or a USB wireless adapter.
