Receive Signal Strength Indicatior (RSSI)

The 'associated' command shows the signal strength and noise levels for radios in the same bridge

group. To see close to real time RSSI, add the "watch" command after the "associated" command.

AP antenna alignment using the ‘watch’ command:

EION: show interface Wireless 0 associated watch

3.4.4.6. Configuration and Link Test

1. Connect a laptop to the "TO LAN" side of the power inserter the LibraPlus.

2. Conﬁgure unit to the proper center frequencies, etc. if you have not done that previously

3. If the link results are satisfactory, proceed to Step 6 below. If the link is unsatisfactory ﬁrst turn the

antenna in different directions to beneﬁt from beneﬁcial multi-paths. If still unsuccessful look for

another antenna location with better line-of-sight until you ﬁnd a location that is satisfactory.

4. Refer to the troubleshooting guidelines if problems persist.

5. Adjust antenna position to achieve the best Link performance.

6. When Link performance is satisfactory, tighten mounting hardware.

3.4.4.7. Test network connectivity

The next step is to verify that a computer attached to the LibraPlus can communicate with a computer

on the other side of the wireless link.

1. Call up the Network Operations Center (NOC).

2. "Ping" the NOC from the CPE.

3. Have the NOC "ping" the CPE from the NOC. A successful ping test means that the network "sees"

the CPE on the network.

4. Connect the CPE Ethernet Port to the customer LAN or PC.

5. Ping from the Customer LAN or PC to the NOC.

6. Use ftp to send some larger test ﬁles from the NOC to the PC or other IP device on the LAN.

7. Measure ﬁle transfer rates in both directions.
