Please post your QEMU command-line.

The details of QEMU's default networking configuration ("slirp"
userspace networking) is as follows:

Subnet: 10.0.2.0/24
Gateway: 10.0.2.2

Therefore statically assigning a 192.168.1.0/24 address will not work,
you need to pick a 10.0.2.0/24 address and use 10.0.2.2 as the gateway.

If you are using tap networking then this does not apply.  Details of
your host networking setup would be necessary in order to help you.
