Diagnostics

9.2.3. Network Diagnostics

NOTE
If Bolt LTE is installed on a private cellular network, the methods are limited according to the
restrictions of the private network.
NOTE
The methods are useful when evaluating the connection on the cellular network. Complete the
evaluation by performing tests from the connected device on the LAN network.
NOTE
To get reliable network diagnostics results, large amounts of data may be used.
Before running the Wget method, check the SIM card data rate.
The network diagnostics methods work for both modem devices and for LAN interface devices.
Procedure
To perform a network diagnosis:
1. Select the Method.
Method Description
Ping Ping sends packets to the specified address and then waits for the response.
Some devices do not expect longer round trip time, introduced by cellular network connection.
Use ping to measure the round trip time.
Ideally, measure towards the host that your device connects to, or another host at a similar distance. The host must be
configured to respond to these types of requests.
If errors exist, ping reports the errors.
Ping can also show packet loss.
If the host's IP address is known, start by pinging the host's IP address and then the host's DNS name. The DNS name is
dependent on name server lookup.
To verify that Bolt LTE is connected to internet, you can send a ping to a host or an IP number capable of returning ICMP echo
responses, such as Google Public DNS.
In the Target field, enter the IP address (IPv4) 8.8.8.8 or 8.8.4.4.
Nslookup Nslookup is used to query internet domain name servers.
When Nslookup is run, the IP address of the DNS server and the targeted host IP address are shown. The DNS server is usually
specified by the network operator.
Wget Retrieve files using HTTP.
The retrieval can help you evaluate the real download capacity of the connection. The retrieved file is not saved to the Bolt LTE.
Wget can be used to evaluate performance. The reply message shows the elapsed time between the request being sent to the
Target and the response being returned.
2. Enter a Target.
3. To Perform Action, click Start.
The request is sent to the target. When the target response returns, a message appears.
