This exercise demonstrates the concept of designing a Home
Network with a Router, Access Point, and Wireless Work Stations. -I
A network administration has configured various components of the network as below:
DHCP Range on Server:
Access Point (AP1):
Router R1 configuration:
Subnet mask: 255.255.255.64
Client Configurations: All workstations have been configured to obtain the IP settings from DHCP server.
It was reported that none of the workstations are able to ping the Router R1s E0 interface
(Default Gateway). The technician had checked all the physical connections are found them
to be in order.What is the most likely problem?
In the above scenario, the DHCP scope was set wrongly on the DHCP Server. The DHCP
scope of 192.168.1.65 to 192.168.1.128 corresponds to subnet ID 192.168.1.64 where as the
default gateway (192.168.1.1) corresponds to subnet ID 192.168.1.0. By correcting the
DHCP scope to 192.168.1.3 to 192.168.1.63 (note that 192.168.1.1 and 192.168.1.2 have
been used for static assignment) the problem could be solved.
1. Open the Server configuration window.
2. Change the Start IP to 192.168.1.3 and Stop IP to 192.168.1.62 (Note that 192.168.1.63 is
broadcast address and cant be used. 192.168.1.1 is the IP address of default gateway, and
192.168.1.2 is statically assigned to DHCP Server).
3. Ping to default gateway should success.
