    I have 1 x 2811 router and 2 x pc's in the network all are switched on, i assign the pc's with manual ip's of 10.0.0.10(fastethernet(pc) to fastethernet0/0(router)) and 10.0.0.11(fastethernet(pc) to fastethernet0/1)(router)) and connect both pc's to the router using a straight through cable.

    So i try an ping the other pc from one pc and i get request timed out what am i missing in the setup?

    So you have a configuration similar to below:

    PC---------f0/0 Router F0/1---------PC
    10.0.0.10 10.0.0.11

    A couple of things you might want to take a look at here.

    1. The addresses of your 2 PCs, note how they are on the same network, keep in your head the purpose that the router is actually serving, try assigning them ip addresses from 2 seperate networks.

    e.g
    network 1: 10.0.0.0 mask 255.0.0.0
    network 2: 11.0.0.0 mask 255.0.0.0
    PC1 = 10.0.0.1
    PC2 = 11.0.0.1

    2. Check your cable types: If devices share the same layer of the OSI layer or there is 2 layers of difference between them then the cable should be a crossover. If there is 1 layer of difference then its a straight through.
    e.g
    layer 1: repeaters, hubs, pc's
    layer 2: switches
    layer 3: routers
    so pc to switch = cross over cable
    pc to router = cross over cable

    3. Don't forget to also assign your router interfaces (default gateways) ip addresses as well and to issue the no shut command.

    Best of luck with the studies, stick at it it'll be worth it in the end.

    PC to switch should be straight through right, you have cross over, there is only 1 layers difference not two??

    Not sure if i am reading your post right, but it sounds to me like your are trying to span the same subnet over the x2 interfaces;

    fastethernet0/1 needs another subnet configured on it

    ie.
    set fastethernet0/0 to IP 10.0.0.1/24 ---->PC IP address 10.0.0.10, subnet 255.255.255.0, gateway 10.0.0.1
    and set fastethernet0/1 to IP 10.0.1.1/24 ---->PC IP address 10.0.1.11, subnet 255.255.255.0, gateway 10.0.1.1

    On another note, on most new routers (the 2811 included) the ports have auto-cross over capabilties or MDI/MDIX as it is also know - not sure if this is the case in the router SIM ....

    Yep that's right my bad, should check what I type more carefully.
