Networking problems for pros?

I have a linksys wireless router set up in my room. It splits the internet between my room mates laptop and another laptop. As it stands, anything after the router is in it's own network. My problem is the building I'm in has it's own network (has something to do with an ultra pier) and I want to be a part of that newtwork as well. My main computer has two LAN connections and I've tried to connect one cable to it and one to the router but the internet stops at my computer. My main objective is to connect to the network in the building for networking with itunes and still be able to transmit my own network wirelesly. Also I only have one intenet connection in my room.

Networking problems for pros?
Or the school is already providing a private network...


does your room have an ethernet port in the wall?


connect from the wall to your linksys in the 4port switch area.


then connect your desktop to the second port and laptop to the third unless you want to be wireless...as far as your router goes you do want to disable dhcp and you also want to disable NAT and on the status page release your ip, its probably all zero's already. as far as wireless on the router - set up the SSID and disable broadcast so other kids dont see it and set encryption and if you want setup the MAC address filter so that only wireless connections with matching MAC addresses get to connect if they got a key and know the SSID...


On the wireless laptop go to network properties and right click the wireless connection and choose properties and then switch to the wireless tab and configure the SSID and encryption key there.


This is assuming you have Windows XP.
Reply:I bet your problem is you have the two networks using the same address range.


If that is the case, then you will have routing problems.


Try this:


Only connect to the Intranet of your building (disable your wifi).


In a windows command window, type ipconfig


take note of the ip address, ipmask and gateway address.


Then disable that network and connect to the wifi router.


Again do ipconfig and take note of the ip address, netmask and gateway.





If the addresses do conflict, then change your wifi router settings,


Typically you would change its IP address and its range of dhcp addresses.
Reply:Sounds like you want your main computer to serve as a gateway or proxy for your router so then your laptop (and your friend's laptop) can access the internet. Two ways you might be able to do it. 1) Try Microsoft's Internet Connection Sharing feature. I wouldn't touch it but you're welcome to experiment on your own. =) 2) Go to www.handcraftedsoftware.org and download FreeProxy. Install FreeProxy on the computer with the two network connections. Fiddle around with the setup and make sure it's running (the base settings will pretty much work right off the bat). Then set the programs (iTunes, Internet Explorer, FireFox, etc) on your laptops to use a proxy server: give it the NAT IP address of your computer with FreeProxy. (The NAT IP address is the one that is being provided by the LinkSys router.)





I am using a similar model to share a single internet connection at my home. I have a laptop with a Cingular 3G internet card and FreeProxy. When I bring my laptop home from work I plug it into a hub. All my home computers can then access the internet through the proxy on my laptop. I used this method instead of Microsoft's Internet Connection Sharing because Microsoft installs a mini DHCP server with it's Internet Connection Sharing feature. A DHCP server on my laptop would be a big "no no" at work. I should know, I'm a SysAdmin. LOL.
Reply:Start from square one and restate your question. Start with your pc, how it connects to the net, whether you are connecting to the complex network to get to the internet or you have your own internet provider, and lastly, just what you want to connect to what! Sounds like you got a wet dream goin on!
Reply:go into the router, and disable DHCP. Now your router is a wireless switch, hopefully DHCP is distributed by the main network. If not, you'll need the network settings from the admin. You and your roomate will become part of the main building network. If you set your own workgroup name, then just you two will be part of that workgroup. Have automatic IP address on the computers. On the laptops, have the same SSID and WEP or WPA key as the router. Disable one of the LAN ports on the main computer, and connect the other to the port on the router.





Building network-%26gt;Router-%26gt;your two (or more) computers wirelessly or wired into the router.





Good luck!
