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.

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.

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?
