Dear friends, I wish to solicit your help in configuring a peculiar setup at home as depicted in the picture attached. I am basically trying to bridge three networks together: ( A ) A Linksys wireless router with its wirelessly connected devices, mainly a desktop in BR2 and a laptop in BR1 or Hall ( B ) Two (crossover) ethernet networked PCs forming my home studio in BR3 and ( C ) A Linksys Wireless Ethernet bridge connected hardwired to a WD NetCenter NAS drive also residing in BR3. Here is an explanation of the schematic drawing: - A Motorola cable modem is located in BR1 which then connects to a Linksys Wireless-G router WRT54G positioned in the Hall (at a somewhat central location). A laptop with inbuilt wireless adaptor is generally operated in BR1 or in the Hall wherever convenient. - In a somewhat distant room BR2 there is a general purpose computer with a Linksys USB wireless adaptor WUBS54G. A printer (with no networking capability) is also attached to the USB port of this computer which is to be shared over the wireless network. - In a third bedroom BR3 adjacent to BR2 is my recording studio that comprises two PCs (alongwith a huge list of equipment and software) which I plan to wire together in a crossover ethernet network. Normally these machines shall be dedicated to recording and will have nothing to do with the rest of the house or its elements. - However, these two machines in BR3 will, though very rarely, need to go online only for registration and downloading of software / windows updates etc. For this, each of them has been given a Linksys USB wireless adaptor WUSB54G. - A WD NetCenter NAS Drive with one Ethernet port is positioned in the studio for backing up. Since this is located in BR3 I purchased a Linksys Wireless-G Ethernet Bridge with a single ethernet port to connect the NAS Drive so that it can be used to back from all PCs all over the house. While connecting the above is easy, a few issues are bugging me: 1- Is it possible that I am able to connect to the internet wirelessly and without unplugging the crossover cable? I understand that Windows XP gives priority to ethernet connection over wireless. 2- IP address. Since I shall be basically trying to bridge the three networks A, B and C together there could be an issue of IP Addressing, meaning a need to change IP Addresses may appear each time there is a need to connect the two studio PCs to the internet and back to its original configuration of ethernet crossover connection. In other words, for example currently for the wireless router network, the IP addresses are 192.168.1.50 for the wireless laptop and 192.168.1.51 for the wireless desktop. So ideally for the I should be able to configure 192.168.1.52 for the first crossovered PCs, 192.168.1.53 for the second crossovered PC and 192.168.1.54 for the NAS Drive on the bridge. That's for wireless. But now if I want to revert to making music on the crossovered network (hardwired PCs) will the same IP addressing work? Would love to hear from someone.
