    Default Need help to set up WLAN

    Hello everyone

    I currently have a small LAN here at home to share my DSL connection and files for my 3 computers.
    The connection is shared through the first pc, and I just used windows set up wizard to do that and it has been working nicely for some years now.
    But now I am planning to change my DSL connection for a faster cable connection, but I would have problems to pass the cables here at home, so I canít stick with the set up I'm using now.

    So I was wondering if there is a way to set up a wireless network with my current LAN, but I understand very little about WLANs and how to configure them.
    I just want to put a wireless router where the cable comes into my house and distribute the internet on my current switch hub, and also if itís possible share my documents and the internet to a laptop computer or other WI-FI devices.
    And I also want to know if that setup works, how I can secure all the data I share among all my computers and the internet connection itself so other people canít see or use my network.
    I hope you guys can understand what I want and can help-me so I did this little scheme:


    Thanks in advance.

    I'm no network wizard but I do think that you will find that the whole network will be much easier to manage, (as well as faster online and more secure) if you could hardwire directly to your hub rather than haveing everthing limited to wireless speeds. Simpler yet: skip the hub and use a multiport router (with wireless capabilites) at the access point. If you are like most of us the only thing that would really need wireless access would be the laptop. If you are using a decent router at your access point it should already have NAT on it so that all the outside world can see of your network would be the router itself. The only real weak point in the system is the wireless part and that can be set up with encryptions so that only those devices with the proper key can access the connection. It is always a good idea to install a firewall on all computers as well. No system is 100% safe from a determined intruder.

    That is the problem Iím trying to solve with this set-up, I want to keep my wired network because itís faster and more secure, however the cable for the internet wonít fit the tubes on the wall, because I already have 2 telephone lines and 1 satellite TV cable there.
    I donít know anything about Wireless networks, so I donít know if I understood you correctly.
    You are saying that I can put a multiport router where the internet cable comes in, and another one to use instead of my current network hub, and this way I can share the internet among my 3 computers just as I do today?
    If so that exactly what I would like to do, but routers are more expensive so I thought there was something cheaper to connect the router to my current hub, I was thinking that I could just plug an access point to the uplink port of my hub and it would receive the internet from the router and route it trough the network.
    Is it possible and would it allow the laptop to access only the internet but not the files shared on the network?
    Thanks again for replying.

    yep - most AP's have a client mode where you can get it to connect to another access point - its configurable by the web interface

    Would the network be secure or any one will be able to see my shared documents?

    Well, I just set up a network for my parents. I found a site - portforward.com that should help you a little.

    Here is how to setup the security:
    What brand is the router and adapter? Have you installed the software for each adapter on each computer (except the wired computer)?
    -What you need to do is type in the IP address into the internet browser - ie, mozilla, opera, etc. That part should be covered in the portforward site.
    -The portforward site should give the default user and password to login.
    -Depending on your router, it should have something about security. I chose WPA because WPA2 hurt my signal since the other networked computer is far away. WPA2 has the best encryption.
    -Be sure to enter a good password other than "password."
    -In the bottom right hand corner of the screen, you should see an icon for the "Wireless Connection Monitor."
    -Click on "View Wireless Networks."
    -Choose your preferred network and enter the password that you chose earlier.

    Depending on your setup it could change a little from this.

    depends if you turn on encryption or not and what sort of encryption WEP is hackable, though to perfectly honest most people wouldn't bother, there are plenty of unprotected wifi ap's out there

    I think u can buy a NETGEAR DG834G which is an Access Point,Wireless Router & a Broadband ADSL modem all in all & also priced very less compared to other comanys.

    Just plug the ADSL line to the router.Buy wireless PCI cards for each of ur PCs.If u don't have wireless card for ur Laptop buy a PCMCIA Wi-Fi card.Install the drivers on all the computers for the Wi-Fi cards.After powering up the router,open a web browser window on the connected computer and type http://192.168.1.1 into the address bar and press enter. This will take you to the Netgear Smart Wizard welcome page, click OK to begin the configuration. The router will attempt to detect the type of connection you have and the next message you receive should be Dynamic IP (DHCP) Detected.Leave the DHCP on. click Next once you see this. Choose the no security mode when u see the security tab.
    After installing all the WiFi cards, u'll have to search for the wireless signal from the router on all PCs.If the wireless signal is detected, u'll see that a no secure network has been found.Connect to that network.Don't forget to make all ur computers DHCP enabled after installing the Wi-Fi card drivers.

    When u choose connecting to a non-secure network, ur PCs & the laptop will get connected to the Wireless router & then u can access the internet & u'll have to enable sharing on each computer.When u do this, u'll be able to acess every resources on each PCs from every PCs.

    If u would like to secure ur home network(not needed though) , u'll have to remember a lot more things.

    AMDATHLONFX, Rody has already stated that he wants to have a secure network. Leaving a network unsecured is not an option for most people and should not be done if one values privacy at all. An unsecured network leaves all connected computers much more open to prying eyes as well as giving someone the ability to download anything he wants on your connection. The thought of haveing some doorknob downloading kiddyporn through my ip number is not an option.

    Your idea for the network would prolly work but in my experience wireless is nice for portability (laptops) but is not as fast or stable as a wired connection. Wires are a pain to route but are well worth the trouble.

    Yep, i agree with u.Wired connection is much more secure & fast too & for that we won't have to remember all those WEP & WPA things.I've suggested to have a wireless network bcoz he said that he was wondering if there is a way to set up a wireless network with his current LAN.I also am using an wired DSL connection shared wirelessly to my laptop.I'm also using Wi-Fi WPA security but as he said that he is new to WLAN, I've written how to establish a non-secure connection so that he won't have to go into those security stuffs.Being a network professional,I know how much network security is important.That's why I've also posted a link about how to setup a secured connection.
