No, No, No, "Aquiring Network Address" means your DHCP is in the process of attempting to obtain an IP address for your connection. Everytime you turn on your computer from a state of complete power off, the Router must again aquire its IP Adress from your ISP and then reasign each computer a private address. This is normal behavior and usually resolves itself quickly when you first boot up. If it is stuck on the "aquiring network address", then there is a problem between the Router and your Cable or DSL Modem. Do you have a requirment by your ISP to use a User Name and password in the Router? Have you properly installed the software in the laptop? Are your settings correct in the Network Connection your are attempting to connect to? It takes more than a simple built in Adapter in your laptop. Did you run the Network Connection Wizard on your laptop? There are several problems this may indicate.
Listen, your best bet is to use your Routers technical support. They can talk you through properly establishing connecting your laptop to your wireless network. It is simply too much to write here. Also, why are you still unsecured? You do realize that you risk an invasision into your network, that your files are all at risk and somebody could conceivably take over one or more of your computers?
This is a great book, "Absolute Beginner's Guide to Home Networking", by Mark Edward Soper. It is about 350 pages filled with super information which is easy to follow. It takes you through setting up a home or small business office network with either cable, wireless, or a combination. It also has detailed steps in hooking up other items to a network like a game console a media adapter, t.v. stereo system, etc. I used this book exclusively to build my own wireless network and will continue to use it as reference as my needs expand with my network. The book is not expensive and you can find it at any local book store or a Fry's Electronics store.
Please consider securing your network as soon as you have established the connection between your laptop and your network. This is of vital importance. If you can use WPA eccryption, not WEP, as it is much stronger. Even with this security, and a firewall in your router, please also use a strong software Internet Security Suite with a firewall, anti-virus, and other malware protection. Just last week I had a curious neighbor who cracked through my encryption and attempted to penetrate my networked computers, my Panda Internet Security stopped the connection.
Good luck and I hope you fiix this problem soon and secure your network. If you run the software for the adapter of the same manufacturer as your router and use that adapter iinstead of the one which comes built in the laptop you should have no trouble connecting. I have guests who use the adapter I keep for the laptops they bring when visiting and once the software is run and they pop in the adapter they connect without any trouble at all. Just using the adapter which comes with the laptop has a hit and miss connection at best. So, while in theory these built in adapters are suppose to connect easily, I have found it not quiet true.
