Configuration works in packet tracer, but not on phycical hardware?

Hi, me and my mate are having trouble solving an issue.

It's so basic that I'm getting so frustrated about it.

We have;

• 1 Router

• 2 Switches

• 2 PC's

Here's the configuration:

Interface GigabitEthernet0/0 192.168.30.1 | 2555.255.255.192

Interface GigabitEthernet0/1 192.168.1.29 | 2555.255.255.128

PC1 192.168.30.30 255.255.255.192 (Default GW; 192.168.30.1)

PC2 192.168.1.29 255.255.255.128 (Default GW; 192.168.1.1)

SW1 FA 0/1 -> G 0/0 & FA 0/2 -> Client PC

SW2 FA0/1 -> G 0/1 & FA 0/2 -> Client PC

Important information;

• There's no internet connection.

• Router and Switches are both connected to a domain.

• Clients are not connected to a domain.

• PC1 can ping both G0/1 & G0/1

• PC2 can ping both G0/1 & G0/1

• PC's cannot ping each other (The request got timeout)
