Failover is becoming essential for business-grade connections to keep services online and minimise any downtime in the event of an unscheduled outage. Enabling Kern 4G LTE failover enables a redundant secondary path that automatically switches over seamlessly, using the same public fixed Kern IP, in the event of your primary KernWi-Fi / Kern Fibre / Kern nbn™ link going down so your business stays connected.

What Our Clients Say
We have been working in Adelaide since 1990 and have thousands of happy customers both business and residential. Below our just some of our testimonialsLiving in Athelstone I knew I was in a dead spot. I tried both Telstra and Optus with no luck and no local service, was always over the phone with someone from another country. Went a year with out Internet until I found KernWi-Fi. I have been using them for over a year now and have high speed internet and haven’t had my service go down either.
Anton- Athelstone
I was refered to KernWi-Fi from my hairdresser who had been using them for some time. I have been really happy with the local adelaide service. More importantly my internet is 100% faster than before.
Eric – Adelaide
Kern could not have made getting a Broadband Wi-Fi connection in easier for me. After I registered on their website, they made personal contact same day, organised a site survey for the next day and I was up and running a couple of working days later with a stable high speed connection. I have not in the 20 years I have worked in IT received better nor friendlier service dealing with an ISP for either personal or business connections.
