Consequently, it is vital to know and understand the history of ping tests and how ping tests work. Tanaza is launching an improved ping tool, to help MSPs execute routine ping tests and stay up to date on the networks’ performance.
What is a ping tool?
The ping measures the time that takes for packets to arrive at the destination host from the requesting host and back. This tool is useful for troubleshooting WiFi networks and test responses. Also, it provides users with the exact location where a specific problem may exist in the network.
For example, if the connection to the Internet goes down in a specific location, the ping utility can be useful. It helps to better understand where the problem exists if it is within a particular AP or the WiFi network.
How does the ping tool work?
Once the user inputs the information and clicks PING, the system starts immediately pinging the intended device. After the attempts are over, the tool displays reached information values for average latency, loss rate, and jitter. Also, it shows a full history of the console. Users can also restart the ping if needed.
Also, users can set advanced settings like interleave, packet size, attempt counts, and timeout, in the advanced mode tab. Moreover, users can carry out multiple pings in parallel, with a maximum of 10 ping instances happening at once.

How to read data from the ping tool
1. What is Latency Rate?
What would be an acceptable Latency in WiFi networks?
Typically, a wired connection has a latency of 1 millisecond or less. Whereas a wireless connection should generally be in the range of 1 to 3 milliseconds. The reason a wireless connection experiences more latency is due to the operation of encryption and decryption that it needs to go through, which in general lines takes more time compared to a wired connection. The wired connection only needs hardware operation and transmission, and as a result, the latency is much less.
Last but not least, the network signal is another key point to factor in. The higher the network signal is, the lower the ping would be. So, network managers know that the speed related to their networks depends mainly on signal quality.
When the average latency figures in networks (wired or wireless) go above the aforementioned threshold, that’s when network managers should start to worry. If latency figures, go as high as 4-6 milliseconds, it means the network is heavily congested. Also, it could mean that networks might be experiencing lots of collisions. Any figures beyond 4-6 milliseconds, it means poor WiFi connection or also interference caused by other devices nearby.
2. What is Jitter?
In a network, the sender forwards packets spaced evenly apart in a continuous stream. However, if the WiFi network is congested packets start queuing. Also, if there are errors in the network configuration, it can result in significant variations in packet delay. This means that packets will not be received in the same order or possibly drop entirely on the way.
When MSPs are in the presence of high-level jitter variations, it can only indicate problems within the network. For example, web browsing is highly resistant to jitter, however, streaming data, voice, or music is much more susceptible.

3. What is Packet Loss?
A packet is a small unit of data carried over a digital network. Data packets follow a defined path to keep the efficiency in networks. However, before a data packet is sent to the receiver, it is evenly distributed into blocks of information. Once the data packets arrive at the destination, they reassemble again.
Why does packet loss happen?
Thus, when packets are not successfully delivered, it slows down the speed of network traffic, as it causes a blockage. This creates a sort of congestion in the network throughput and takes upon bandwidth.
The risk of not acting soon to reduce the percentage of lost rate can be costly for MSPs. Investing in additional IT structure and adding more bandwidth to fix the latency caused by packet loss, would be needed.
What are the causes of packet loss?
Other reasons for packet loss could be overloaded devices or issues with the network hardware. Also, inadequate structure for handling packet loss, and even security threats in the network. However, there are ways to prevent packet loss, although it’s worth highlighting that it’s impossible to achieve zero packet loss. There will always be issues in the network, multiple client devices connected at the same time or overloaded devices. This would make it extremely difficult to achieve a zero % loss rate.
What can MSPs do to troubleshoot networks?
Troubleshooting networks with high levels of Latency and Jitter
Hence, a slow connection speed would cause high latency. The more interference, the lower the bandwidth available to use. Finally, the more client devices connected to the network, the higher the variation in Jitter. Also, connected devices that aren’t transmitting data cause more interference, thus increasing levels of Jitter.
Apply these hacks to reduce latency and jitter levels
2. One of the key recommendations is to reduce heavy users and get them to connect to the Ethernet, to take the load off from the WiFi network. However, in outdoor – medium and large scale deployments, this is not scalable, to not say nearly impossible. With the Tanaza platform, MSPs can limit the amount of bandwidth at the SSID and client level.
3. Assess the channel bonding of your wireless networks. For instance, newer devices allow users to have 40Mbps channels on the 2.4GHz and up to 160Mbps on the 5GHz. To lower the latency is essential to have more bandwidth.
4. Deploying more WiFi access points will help to increase the signal and provide more bandwidth, in consequence, reducing levels of latency and Jitter.
5. Set up multiple access points using different frequencies rather than using repeaters, which unfortunately help wasting bandwidth.
Troubleshooting WiFi networks with high packet loss rate
Try these simple tricks to fix packet loss:
- Check all connections are properly configured and plugged-in correctly.
- Restart the whole system. It might give a clean jumpstart to the network pushing it to fix internal glitches or bugs.
- Remove any application or devices capable of causing static, like Bluetooth, wireless devices, and cameras.
- Use an Ethernet cable connection instead of WiFi. Packets tend to get lost easily over WiFi. Consider even a fiber optic cable to connect to the Internet.
- Consider, also replacing legacy hardware and look out for the network infrastructure, too.
- Deploy more access points. This will increase the signal and provide more bandwidth, thus reducing jitter and latency.
