2026-07-18 Will EFTPOS, VoIP phones or remote desktop sessions notice when the internet changes from NBN to mobile backup?

Some applications handle failover quietly, while others may briefly reconnect or re-establish sessions. That is normal, because the public-facing IP path can change when traffic moves from the fixed service to the cellular network. The important thing is whether the interruption is acceptable for the business process and whether the design has been tested under live conditions. Comset’s role here is usually to match the failover design to the application.…

2026-07-17 Can a Comset router automatically take over if my office NBN fails?

Yes, that is one of the most common use cases. The router watches the primary WAN connection and can switch traffic to the mobile service when the fixed link fails. The details matter, though: the failover trigger, the return-to-primary behaviour and the way services recover can all affect how seamless the experience feels to users. For a straightforward office backup, Comset will usually want to know what services must keep running, how many users are in…

2026-05-30 How can a router return to the primary WAN connection without creating repeated failover and failback instability?

Use separate failure and recovery thresholds. For example, the router may switch to cellular after several failed checks but wait for a longer period of stable primary service before returning. This prevents a marginal NBN or fixed-WAN link from pulling traffic back and forth every few seconds. Health checks should use more than one dependable destination where possible, and the timers should reflect the application’s tolerance for interruption. Some VPNs…
