    Post CISCO Packet Tracer WLAN Problem.

    Can anyone please tell me what's wrong?
    This is for my school project.
    I can't connect the computers from office to internet cafe and vice versa; internet cafe to office. Also, I am using a wireless router so that employee's and customers who owns a laptop can connect to the internet via wireless.
    Can anyone please help me? I really need this for my school.
    My teacher taught us the basics and then she said to explore the application, but I can't use the things she taught to me. There are a lot complicated things needed to do to make a perfect lan/wlan setup. Tried to explore like she said, but no help.
    This is he outline of my work:
    1.) The cloud represents the internet service like Globe, Smart, PLDT, Bayan. These are Philippine Internet Service Providers.
    2.) The DSL is given by the provided in order to connect to the internet.
    3.) I am using linksys wireless router for wired and wireless connections.
    4.) I used two switches connected to the router for lan.
    5.) There are two rooms here. The first room is the office room, consisting of one server, seven computers, and three wireless compatible computers as laptops. The second room is the internet cafe, consisting of one server fourteen computers and one wireless compatible computer as laptop.
    6.) I will be the one to take care of sub-netting.
    7.) The people with laptops or wireless can connect to the computer, but they will not be allowed to connect to the lan.
    Here is my work. It was created with CISCO Packet Tracer 5.3
    Code:
    WLAN.pkt
    If ever you solved the problem, please tell me what you have done.
    Thank you for your kind consideration.

    Switch one of your internet cafe PCs to pull a DHCP address and you'll see what network is it physically attached to. It looks like the static IPs you assigned belong to the network segment between the Linksys & the DSL Modem.

    #7 sounds like something you might use an ACL for -- but I'm not really sure from the description what shouldn't talk to what? Were these the devices you were told to use? Or can you toss in another device? Are the Cafe & Laptop users not supposed to access the Office PCs/Lan? If that's it, then you'd need those office PCs on their own LAN.

    You can just toss in another device. And yes, they are not allowed to connect to the lan, they can just surf the web.

    Are the office machines the only wireless computers?
    Are the cafe computer and customer laptops always "wired?"
    Or can some of the customer laptops also be wireless?

    You only have one "the lan" right now -- so if the cafe & customer laptops shouldn't access the Office Lan PCs, you need to create an Office Lan -- and adjust your network and move or add hardware as needed.

    Actually, the teacher want's the wired computers can connect to each other vice versa; internet cafe to office and office to internet cafe. The employees and customers who has laptops are not allowed to connect to other wired computers because they are just guests who provided their own equipment. That means if they want to transfer files to other wired computers, they need to use removable devices. I'm going to show you one of the work of an IT Specialist that I referred. The problem with this one is, that there is no wireless lan so will the people with laptops can connect to the internet? Second, there is no dsl and cloud, so they can only file share, but they can't surf the internet. I really don't what this one contains because most of this one was done by the IT Specialist, and he went abroad so I lost contact to him, and I can't tutor with him anymore.

    Sorry for misunderstanding your earlier post. My reply meant that the internet cafe and the office can file share and surf the internet. While the laptops can only surf the internet. So are telling me that I need to use another router?

    Adding a "real router" like an 1841 would allow you to have the customer laptops in one network and the wireless office PCs and Internet Cafe PCs in another and then apply an ACL somewhere to keep the customer PCs from accessing that Office/Internet Cafe Network -- while everyone can get out to the internet.

    You can either have multiple Ethernet Interfaces in the router -- one for each network you need to create, including one for the link from the router to the DSL modem for internet access. Or you can use one of the 2 built in FastEthernet 1841 interfaces for the connection to the DSL modem and then trunk the switches together, implement VLANs for the different networks, and use the 2nd 1841 FastEthernet interface to do "router on a stick."

    Where's your access list to prevent the customer laptops from accessing the office/cafe PCs?
