4.3 Testing Radio Paths

The general procedure for radio range testing a link is fairly simple. Configure two units to form

a link using automatic radio rates. Install the Access Point at a fixed location. Take a laptop

computer and the Client to each of the remote locations, and analyse the link using the

Connectivity webpage. If a beacon is heard from the Access Point, the Client will update its

Connectivity webpage with the received signal strength of beacon messages from the Access

Point.

The RX led on the Client should also be observed. If the RX led flickers red, then the signal

strength is weak. If the RX led is always green when a message is received, then the signal is

strong.

If the signal is strong enough, a link may be established, and the Connectivity webpage of the

Access Point may be opened. If the link is weak, the LINK led will go out, and the remote

Connectivity webpage of the Access Point will fail to load. Using this procedure, the signal

strengths of units at both locations may be analyzed, and traffic is sent between the units whilst

remote webpages are opened.

4.4.1 PING

Ping is a basic Internet program that lets you verify that a particular IP address exists and can

accept requests. Ping is used diagnostically to ensure that a host computer you are trying to

reach is actually operating. If, for example, a user can't ping a host, then the user will be

unable to send files to that host. Ping operates by sending a packet to a designated address

and waiting for a response. The basic operation of Ping can be performed by following these

steps in any Windows operating system.

Click on the Start Menu and select Run. Type in “cmd” and enter, you should then see the

command screen come up. There will be a certain directory specified (unique to your own pc)

with a flashing cursor at the end. At the cursor type the word “ping” leaving a space and the

default IP address for the 805U-E at first startup.

This command would be written as Ping 192.168.123.123 then Enter to send the ping

command. The pc will reply with an acknowledgement of your command and if your 805U-E

is correctly configured your reply will look something like this.
