9.2.3 Network Diagnostics
If Anybus Wireless Bolt IoT is installed on a private cellular network, the methods are limited according
to the restrictions of the private network.
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.
Before running the Wget method, check the SIM card data plan.
The network diagnostics methods work for both modem devices and for LAN interface devices.
Perform a network diagnosis:
1. Select the Method.
Method
Ping
Nslookup
Wget
2. Enter a Target.

Description
Ping sends a packet to the specified address and then waits for the response.
Some devices do not expect longer round trip time, introduced by some supported network
types, such as NB-IoT.
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 thatWireless Bolt IoT is connected to internet, you can send a ping to Google Public DNS.
In the Target field, enter the IP address (IPv4) 8.8.8.8 or 8.8.4.4.
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.
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 Wireless Bolt IoT.
