A reliable wireless network is essential for both homes and businesses in Auckland. Whether you’re working remotely, running cloud-based systems, or streaming at home, slow or unstable Wi-Fi can quickly become disruptive.
At Advanced Computers, we regularly help Auckland customers diagnose wireless issues that range from simple configuration problems to poorly designed network layouts. The steps below reflect how our technicians methodically identify and fix Wi-Fi problems — and how you can do the same before calling in professional support.
1. Start With the Device, Not the Network
Many wireless issues are caused by the device, not the router.
Common problems we see include:
-
Wi-Fi disabled accidentally
-
Outdated network drivers
-
Corrupt network profiles
-
Power-saving settings reducing signal strength
What to check first:
-
On Windows 10/11:
Settings → Network & Internet → Wi-Fi → confirm Wi-Fi is on -
On macOS:
System Settings → Network → Wi-Fi → confirm it’s connected to the correct network -
Restart the device after making changes
If only one device is affected, the issue is almost always local to that device.
2. Check Signal Strength and Router Placement
Wi-Fi signal quality drops quickly when blocked by:
-
Concrete or brick walls (common in Auckland homes)
-
Metal framing
-
Large appliances
-
Distance from the router
Best practices we recommend:
-
Place the router centrally in the home or office
-
Keep it elevated (not on the floor)
-
Avoid cupboards or enclosed cabinets
-
Keep it away from TVs, microwaves, and cordless phones
If your connection improves when you move closer to the router, you’re dealing with a coverage issue, not an internet fault.
3. Restart and Update Your Router
Routers run continuously and can develop performance issues over time.
Steps to take:
-
Power off the router for 30–60 seconds
-
Power it back on and wait for full startup
-
Check for firmware updates via the router’s admin page
Outdated firmware can cause:
-
Dropouts
-
Security vulnerabilities
-
Compatibility issues with newer devices
If your router is more than a few years old, performance limitations may be unavoidable.
4. Check the Modem and Internet Connection
If Wi-Fi is connected but there’s no internet, the issue may be between your modem and your Internet Service Provider (ISP).
How to test:
-
Power-cycle the modem (unplug for 30 seconds)
-
Check all cables are firmly connected
-
Test a wired Ethernet connection directly to the modem
If wired internet also fails, the issue is likely with your ISP rather than your Wi-Fi equipment.
5. Confirm There Are No ISP Outages
Occasionally, outages affect specific Auckland suburbs or exchanges.
Before spending hours troubleshooting:
-
Check your ISP’s website or outage page
-
Contact their support line
-
Ask neighbours or nearby businesses if they’re affected
This step is often overlooked and can save a lot of time.
6. Common Causes of Ongoing Wi-Fi Problems
From our experience, persistent wireless issues are often caused by:
-
Too many devices connected to one router
-
Old routers not designed for modern usage
-
Poorly configured extenders or mesh systems
-
Interference from neighbouring networks (very common in apartments)
These problems usually require network redesign, not just quick fixes.
7. When to Call Advanced Computers
If you’ve tried the steps above and still experience:
-
Slow speeds
-
Frequent dropouts
-
Dead zones
-
Unstable connections during video calls
It’s time for a professional assessment.
Our Auckland technicians can:
-
Diagnose wireless interference and congestion
-
Upgrade or replace outdated routers
-
Configure mesh Wi-Fi systems properly
-
Secure home and office networks
-
Optimise networks for multiple users and devices
We work with both home users and businesses, and we tailor solutions based on how the network is actually used.
Tips for Maintaining a Reliable Wireless Network
To prevent future issues:
-
Keep router and modem firmware up to date
-
Restart networking equipment monthly
-
Use strong Wi-Fi passwords and modern encryption
-
Review connected devices periodically
-
Upgrade hardware as usage grows
Small changes can make a significant difference in long-term performance.
