Design a Home Network with a Router, Access Point, and Wireless Work Stations I

Previous   |   Next

  Description: 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:

Server Configuration:

 IP address
 Subnet mask

DHCP Range on Server:

 Start IP
 Stop IP
 Subnet mask
 Default Gateway

Access Point (AP1): 

 SSID  CertExams
 WEP  Cert1

Router R1 configuration:

Subnet mask:

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 R1ís 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?

Network Diagram:



In the above scenario, the DHCP scope was set wrongly on the DHCP Server. The DHCP scope of to corresponds to subnet ID where as the default gateway ( corresponds to subnet ID By correcting the DHCP scope to to (note that and have been used for static assignment) the problem could be solved.


1. Open the Server configuration window.

2. Change the Start IP to and Stop IP to (Note that is broadcast address and canít be used. is the IP address of default gateway, and is statically assigned to DHCP Server).

3. Ping to default gateway should success.
