I have a wireless cable modem/router and a PCI-E 1x wireless card in my desktop PC. It works perfectly until I connect my Ethernet cable to my local router and printer, no more internet connection. I am guessing there is a setting somewhere that tells the networking software that the hard wire connection is the primary internet gateway. How do I tell it to use the wireless as the primary gateway?:\
It has nothing to do with the internet (except that your default router may point to your router that goes to the internet and that that router can only be reached through one of both connections, a secondary effect). Only with your network. As it is not normal to have two connections to the same network (and most people do connect only to one network at the time), it is indeed by default the case that only one of the connections is working at the time, priority given to the fastest, the cable.
Are cable and wireless in your case connecting to different networks (at the same time)? Then this can probably been solved.
Are you using network manager or ifup?
I am using KDE network manager. I am using the ASUS PCE-N13 Wireless Adapter in one of my PCI-E 1x slots to connect to the Internet through my Zoom 5350 Wireless Cable Modem. That would be one network. I also have a separate local wired network in my work space. Currently the only devices on that network are my Linksys RVS4000 router and my HP5100 printer (Jet Direct Port). I am guessing that my router is redirecting the internet feed away from the the wireless adapter. I have temporarily solved the problem by connecting my printer to my parallel port. Maybe I need to replace the router with a switch or a hub to solve this problem. I am not sure what difference is between a switch and a hub. Thanks for your help hcvv.

Think of a switch as a smart hub. An ordinary hub will forward every incoming
packet to every other port. A switch learns what devices are attached to its
ports and forwards a unicast only to the correct port, thereby reducing
contention on all other ports. For little networks, it makes very little difference.
NetworkManager is programmed to use the fastest connection available. When you
plug in the wire, it will disable the wireless and switch to the wire. It is
working exactly the way it should.
What is the router on the wired network doing? Does it also have Internet access
on its WAN port?
You should be able to access the JetDirect whichever way your box is attached.
We just need to figure out how to connect the two networks, but the info
requested above is needed.
OK. Found a solution. I purchased a switch for $14, although my router may work if I turned DHCP off. Currently I do not need a switch but I plan to buy a color printer in the future and put it on my wired network.
I manually configured my printer to TCP/IP 192.168.200.112 address. In KDE Network connections I created a wired connection and named it HP 5100. I configured the connection to Connect automatically and Restrict To Interface < Any (Default). In the IP Address tab I selected the Manual Method. I set the IP Address to 192.168.200.111 and the Subnet Mask to 255.255.255.0
Do not put anything in the Gateway, DNS or Domains. This indicates to the software there is Internet access on this network and it over rides the wireless network. Hope this helps some else who wants two or more networks connected to their PC.
