Use supported network diagnostic tools to help identify connectivity, routing and DNS problems.
Mercku software includes network diagnostic capabilities for testing reachability, routing paths and DNS resolution.
Test whether a domain name or IP address can be reached from the router.
View the network path used to reach a destination.
Test whether a domain name can be resolved through DNS.
Mercku software supports these diagnostic capabilities, but the customer-facing Router Web or App entry is not documented for every product and firmware version.
Ping tests whether a destination can be reached through the network.
The diagnostic function accepts a destination host such as a domain name or IP address.
The tool returns the diagnostic output so you can see whether the destination can be reached.
Traceroute helps identify the network path between the router and a remote destination.
Use a domain name or IP address as the target.
The diagnostic output shows the route information returned during the test.
DNS Lookup helps determine whether the router can resolve a domain name.
Use DNS diagnostics when Internet connectivity exists but a domain name cannot be opened or resolved.
The diagnostic function returns the DNS lookup output for the requested host.
Mercku software also includes WAN connection diagnosis.
Checks DNS-related connectivity.
Measures network delay during WAN diagnosis.
Returns WAN connection status information.
The documented diagnostic capabilities include Ping, Traceroute and DNS Lookup (nslookup), as well as WAN connection diagnosis.
Yes. The documented diagnostic interface accepts a host as either a domain name or IP address.
The customer-facing menu location is not documented for every Mercku product and firmware version. If the tools are not available in your interface, contact Mercku Support.
Ping can test reachability, DNS Lookup can test domain resolution, and Traceroute can help inspect the network path when those tools are available.
