Need help figuring out ping test failure

[deshani]

Hi guys. 
I'm currently building a network for my networking assignment. The design is built, ip addresses are configured (except for the wireless devices and connections). but the ping tests keep failing, all packets get lost.
A PCs own ping test passes, but that's all. every other ping fails. i think the problem is in somewhere in the switches, vlans or the routers.

please help, i'm new to this. I have attached the packet tracer file.
thank you.

 You need to create sub-interface on the router. One sub-interface for each vlan you have on the switch. Each sub-interface will be the gaterway for that vlan.

"sub-interface on the router.... One sub-interface for each vlan .... on the switch" .plus 1 subnet per 1 vlan is called ROAS or router-on-a-stick if u interested find it here or online. it is a must subject for any exam and in real world.
