My laptop and my server run on wireless however my server only can start running its wireless chip once its logged in.

In order to access it remotely and put in the passwords I need to use the Dells built in remote management system (Poweredge T110 CTRL+E on start up) I must wire it in. My idea was to:
Plugin a switch under my table and link them together, the one I found (in my garage) is fully capable of assigning computers IP addresses HOWEVER both computers will still need to access the internet through a wireless connection- as the server MUST be assigned an IP by the switch on startup will I still be able to access both networks like this kinda (the wireless network uses the 10.1.1~ range while the switch uses 192.168.~ range):

Wireless Network Connection 1
IP Address 10.1.1.19
Subnet 255.0.0.0

Ethernet Adapter 1
IP Address 192.168.0.3
Subnet 255.255.255.0

I tested this and my internet just stopped working (the internet comes from my wireless) is there anyway I can get around that?

If it is your wish to use the switch, one method is to configure it in this schema:

[FONT=Courier New]                          -----> Server
                          |
Modem ---> Router ---> Switch
                          |
                          -----> Laptop[/FONT]

This will rely on the fact that the switch is a layer 2 device (L2) in the OSI model, and will be transparent to the router. You will then be able to apply for a DHCP lease on startup with your server or laptop, and then switch to wireless once you do not need the connection lease any more. These should all be using the 24 CIDR range of 192.168.0.0.

I had that setup before half my room got bulldozed :(. I need this:

                           

Modem ----> Router ------> Airport - - - - - - Laptop

                                                 /\

                                                 |

                                              Switch -----> Server 

- - - - = Wireless

I found an old level one router with bridge capabilities but i couldn't find a power plug for it so was using a 12V one it uses 5V (the amp output was correct through) it started releasing a smell and heated up around the power port - Should this be safe of not? (The smell seemed dominate through out the devices and it may have simply been the cooling system releasing it)

The method you had described in your schema will certainly work and can provide LAN functionality on the same range including internet access. Your laptop would need to have a bridged connection so that it may provide what you are looking for to the computer(s) behind the switch that is plugged in to the laptops Ethernet interface.

This would of course require your laptop to be on at all times while the computers behind the switch require any access, if that is valid for your situation. You may wish to purchase a wireless router and connect it all with no switches or air port to make the whole network very much more simple than it is with your setup.

Your secondary router is not really required for bridging. I would not run it on an unrated power supply at all, I had done the exact same thing maybe half a year ago and it had quite a smoke show an hour in.

:) Yeah true... Hmph i'll try just joining my laptop and my server- my servers internet dongle is screwing up now (it loses connection every so often :( )

[bbqroast]

Ok I tried to connect them and ended up having to delete my lappys network configuration to get it back onto the wireless (interestingly when I clicked "share my internet connection" a "Ethernet Disconnected" or something akin dialog popped up on Ubuntu)

Also all my network notifications appear about 1 inch from the upper task bar and behave really strangely when the mouse is nearby...

You got it to work?

[bbqroast]

Nope :(
Found another router with bridging compat, another post that one :D
