Networks
Networks, cabling and NBN for Newcastle businesses
Most network faults take days because the IT provider blames the carrier and the carrier blames the IT provider. We supply business NBN and fibre through Aussie Broadband, deal with their business support desk directly on your behalf, and own the fault from the wall socket to the internet — so it gets fixed in hours, not days.
Firewalls and security
Design, hardening and lock-down after a breach. We work with Cisco, Ubiquiti and the major firewall vendors, configure site-to-site and remote-access VPNs properly, and document the rules so the next change doesn't break something.
Switching and Wi-Fi
Structured VLANs, PoE switching and enterprise Wi-Fi that covers the whole building, not just the front office. Our engineers hold Cisco CCNA/CCIE and Ubiquiti certifications, and we've delivered large campus wireless rollouts with Active Directory authentication so staff can move anywhere on site and stay connected.
Structured cabling
DATANEXT has its own cabling division. A few extra outlets, a rack tidy, or a whole new office fit-out — terminated, tested and labelled, with a competitive quote up front.
Business NBN and WAN
Business-grade NBN, fibre and multi-site WAN through Aussie Broadband. We monitor your links, so when a site drops off we already know whether it's the router, the line or the carrier before anyone picks up the phone — and we make the carrier call for you.
FAQ
Questions people ask
Can you fix Wi-Fi dead spots?
Yes. We survey the site, then fix placement, channels and power before adding access points — most 'dead spots' are design problems, not hardware shortages.
Do you do cabling for new office fit-outs?
Yes. Our cabling division handles data and comms cabling for fit-outs and relocations, coordinated with your builder or electrician.
Which network brands do you work with?
Cisco and Ubiquiti by preference, plus the major firewall vendors. We'll work with what you already own rather than insist on a replacement.
Can you sort out our NBN as well as the network?
Yes. We supply business NBN, fibre and multi-site WAN through Aussie Broadband, so one team owns the whole connection from the wall socket to the internet.
