Got a tough problem!!!
I have a laptop connected to the internet via wired LAN on a 10.29.x.x IP. I have a printer hooked to a WiFi router with a 192.168.x.x IP. If I disable the WiFi I can connect to the Internet just fine, but can't print. If I enable WiFi I can print but lose Internet. How do I set it up so that I can have the WiFi and LAN both connected and be able to simultaneously print and have internet? I did it once before, but just had a fresh HDD format and can't remember how I did it.

The wifi router is acting as a DHCP server for the wifi network and you're "obtaining an IP address automatically" on your computer on the wifi interface. With your wifi interface on, you're getting a "default route" parameter from the wifi AP which tells your computer to send all of your internet bound traffic to it instead of out the wired interface. You need to configure the wifi router to NOT issue a default route if possible, or turn off DHCP on your wifi interface on your computer and manually assign an IP address and NO default gateway.

You need to configure the wifi router to NOT issue a default route if possible, or turn off DHCP on your wifi interface on your computer and manually assign an IP address and NO default gateway. I'm guessing that they are both running DHCP servers and the one on the WIFI router is just answering requests faster. Turn the DHCP server off on the router that's not actually connected to your internet connection then power cycle your devices. |

One thing I do vaguely remember is that I had to run a command prompt and use ipconfig to set a priority for it to default to the wired connection as the primary internet connection. Don't remember how, though. There's no reason to do this. What you should do is have your devices set up like this Internet connection cabled into the "WAN" port on your wired router. Wireless router from one if its "LAN" ports into one of the "LAN" ports on your wired router Turn off the DHCP server on the wireless router. This will lay all of your devices on one flat network that can all talk to each other and to the internet as well. |

Make sure your preferred default route is the wired LAN (guessing that is what you want), then add a route to the printer's IP on your laptop. |

dont forget the ip of your printer 192.168.2.3 hmm thats on the same network as your wireless adapter. my solution wont help, as apparently your PC is sourcing printer traffic from its wired connection and not the wireless one, and then I guess the printer does not have a route back to your wired connection's network. hm. we'll have to think a bit more here... |

Basically the second I enable the Wireless network (that the printer is on) Internet Explorer tries to use the wireless connection (with no outside access) instead of the wired connection. |

And if it is what in the Hell are you doing asking for network support on Arfcom GD? Let me guess, you have what we call in the business a "rogue" access point that someone bought on their own? Short answer=yeah. Except that it's been authorized due to the weird operating environment here. |

I think the easiest thing for you to do is get rid of the routing, and make your wireless router act as a switch for your 10.X.X.X network. Then re-ip your printer and other devices. Ideally, we'd like to keep the wireless router completely seperate from the LAN. |

Just configure the wireless AP to function as a switch. |

Then you can use the route /add routing function to modify your routing table in your windows environment to send all information for the 192.X.X.X out of your wireless Ethernet adapter. Instead of the default gateway of your 10.X network.
I would also change your binding order to have your 10.X network first. |

Because he only has one default gateway between the two interfaces, traffic not in the same subnet as his computer will be forwarded to his default gateway. Unless there is a static route in his operating system to tell it otherwise. As the 192 network is locally connected it should have a route to that network with it's adaptor as the outbound interface. The default is just the route of last resort. |

HOLY SHITBALLS, I GOT IT!!!! 
It was the metric. I gave the LAN a static metric of 10 and the WiFi a metric of 20 and BOOOOOOOM! It's all good! well it still doesnt make any sense. I do dual connection with LAN/WAN every day using your exact situation and I dont need any of this GW metric or route trickery. I can surf with my default route being on the LAN and my home PC network on the WAN. they are different networks. |

That route (0.0.0.0) means "anything I don't explicitly know about", or in your case, "the internet". Since the wifi router can't get you to the internet, you shouldn't have a default pointing that way. |

Usually you can get away with "stealing" the DHCP address from the wireless router, copy the IP address you've been given as a static address and leave out the default route (since you get no internet via the wireless link anyhow) Better yet, find an address on the wireless router that isn't in the DHCP pool but is still in the network. Probably have to break down and ask the network admin/boss for that. |
