Frequently Asked Questions — Computer Networking Services

What areas do you service for networking jobs? We service Melbourne and surrounding suburbs, with technicians available across the south-east, inner city, and beyond. If you're unsure whether we cover your area, give us a call on 1300 NERDCORE and we'll confirm straight away.

​

​

How long does a typical networking job take? Most home networking repairs and configurations are completed within one to two hours. Larger jobs — such as running ethernet cabling throughout a home or setting up a business network from scratch — may take a half or full day depending on the scope of work. We'll give you an honest time estimate before we start.

​

​

Do you work on all router and modem brands? Yes. We work with all major brands including TP-Link, Netgear, Asus, Linksys, D-Link, Cisco, Ubiquiti, and all NBN-supplied modem/router units. If your ISP provided the hardware, we can work with it.

​

​

My internet is slow — is that a networking problem or my ISP? It can be either, and we'll find out exactly which one. We run diagnostics to determine whether the issue lies with your router configuration, your in-home cabling, your WiFi setup, or your internet connection itself. If it turns out to be your ISP's fault, we'll liaise with them directly on your behalf.

​

​

Can you fix WiFi dead spots without rewiring the whole house? In most cases, yes. Depending on your home's layout and construction, we can extend your WiFi coverage using wireless access points, a mesh WiFi system, or powerline adapters — without the need to run new cabling. We'll assess your situation and recommend the most practical solution.

​

​

What's the difference between a modem and a router — and which one do I need? A modem connects your home to the internet via your ISP. A router distributes that connection to multiple devices in your home, either via WiFi or ethernet. Most modern units combine both functions into a single device. We'll assess what you have and advise whether an upgrade or replacement is needed.

​

​

Can you set up a separate network for guests or work devices? Yes. We can configure a guest network that gives visitors internet access without exposing your main network and connected devices. This is also useful for separating personal and work devices, or keeping smart home devices isolated from your primary computers.

​

​

Do you set up mesh WiFi systems? Yes. We supply and install mesh WiFi systems from leading brands including Google Nest, Eero, TP-Link Deco, and Ubiquiti. Mesh systems are ideal for larger homes, multi-storey properties, and buildings with thick walls that block a standard router's signal.

Can you run ethernet cable through my walls? Yes. We install in-wall ethernet cabling and fit wall-mounted data points for a clean, professional finish. Wired connections are faster and more reliable than WiFi — particularly for gaming PCs, home offices, NAS devices, and 4K streaming setups.

​

​

Can you connect my business to a VPN or set up remote access? Yes. We configure VPN solutions for both home and business use, allowing you to securely access your network and files from anywhere. This is particularly useful for remote workers, business owners who travel, and businesses with multiple locations.

​

​

Is my home network secure? Most home networks — especially those left on factory default settings — are not as secure as they should be. We audit your network and address common vulnerabilities including default admin credentials, outdated encryption, open remote management ports, and unsecured guest access.

​

​

Do you offer ongoing IT support for small businesses? Yes. Beyond one-off networking jobs, we offer ongoing onsite IT support for small and medium businesses across Melbourne. This includes network maintenance, hardware troubleshooting, security updates, and general IT assistance — so you have a reliable tech resource without the cost of a full-time IT staff member.

​

​

What's your guarantee on networking work? All networking work completed by Nerdcore is backed by our 30-Day Money Back Guarantee. If the issue isn't resolved or returns within 30 days, we'll come back and sort it out — at no additional cost to you.
