6.
After downloading the SpeedFlex file, locate the file, and then double-click the file to start the
application. A command prompt window appears and shows the following message:
Entering infinite loop. Enjoy the ride.
This indicates that SpeedFlex was successfully started. Keep the command prompt window open.
7.
On the SpeedFlex Wireless Performance Test interface, click the Start button again. A progress bar
appears below the speedometer as the tool generates traffic to measure the downlink throughput from the
AP to the client. The test typically runs from 10 to 30 seconds.
When the test is complete, the results appear below the Start button. Information that is shown includes the
downlink throughput (in Mbps) between your wireless device and the AP, as well as the packet loss percentage
during the test.
If the packet loss percentage is high (which indicates poor wireless connection), try moving your wireless
device to another location, and then run the tool again. Alternatively, contact your network administrator for
assistance.
Diagnosing Poor Network Performance
You can try the following diagnostic and troubleshooting techniques to resolve poor network performance.
1.
From the Browser-Based Configuration Pages, go to Monitor > Map View.
2.
Look on the map for rogue APs. If there is a large number, and they belong to neighboring networks,
proceed to the next task.
3.
Go to Configure > Access Points.
4.
Edit each AP record, to assign each device a channel that will not interfere with other APs.
For example, if you have three Ruckus APs, open the Radio B/G Channel drop-down list in each AP
record and choose “1”, “6” and “11” in each of the three. However many APs you have, make sure that
each AP has a fixed channel number not too close to the number of a nearby Ruckus AP.
Starting a Radio Frequency Scan
This task complements the automatic RF scanning feature that is built into the NXA-WAPZD1000 That
automatic scan assesses one radio frequency at a time, every 20 seconds or so.
To manually start a complete radio frequency scan that assesses all possible frequencies in all devices at one
time:
1.
In the Browser-Based Configuration Pages, go to Administer > Diagnostics.
2.
When the Diagnostics page appears, look for the Manual Scan options, and then click Scan.
3.
Open the Dashboard or go to Monitor > Map View to review the scanning results. This will include
rogue device detection, and an updated coverage evaluation.
This operation will interrupt active network connections for all current users.
