Ping Unsuccessful

[Lihon]

I tried to ping a wireless device from a branch to another router from different branch but failed.

[Lihon]

Ohh my bad, but some of the laptops which have wireless connection the DHCP request is successful. But some failed and APIPA is being used, what is the issues here?

[Flavio Miranda]

For the laptops, you need to turn they off, remove the Ethernet adapter, install the WPC300N adpter so that they can connect on the wireless and get IP address. 

[Lihon]

Alright now the Kedah wireless devices have successfully requested the dhcp, but Malacca wireless devices failed and apipa address is being used.

Also I can't ping the printer with other devices outside the its VLan. Next, the switches can't ping each other. Also the perils switch P1 can't ping with Selangor router.

[Flavio Miranda]

The printer needs to be connected using DHCP. If you use static IP it has no place to add the default gateway and you will never ping a host outside the vlan if it has no gateway.

Either you setup a DHCP server on the switch K2 or you connect the printer on switch K1 and it will reply ping 

[Lihon]

what about the switches? I tried pinging them to one and another but failed. And also I tried pinging the switch P1 to selangor router failed too.

[Flavio Miranda]

Switches you also need to add gateway like this . This is for K1. You need to do in all switches using their respectives routers as gateways.

Switch#conf t

 Switch(config)#ip default-gateway 200.88.99.1

 For the switches you also need to setup gateways.

Switch#conf t

Switch(config)#ip default-gateway 200.88.99.1

This is for switch K1 but you need to do for all switches using the respective routers as gateways.

I changed the ports of the servers and switch S1 where I connect them with the gigaethernet port with fiber optic cable and now they can't ping together.

[Flavio Miranda]

If you are going to use fiber, you need to choose one interface on the switch that works with the interface on the Server. As you can see, there many. 

[Lihon]

I choose both gigaEthernet, is it wrong?

[Flavio Miranda]

choose the same kind of interface on both sides.  I am attaching a file with server using fiber and communicating .
