Frustrated with Weak Wi-Fi? Tips to Improve Your Wireless Signal in 2026

Posted on by

Few things are more frustrating than Wi-Fi dropping out mid-Zoom call or buffering during a rugby match. Whether you’re in a concrete apartment in Auckland CBD, a weatherboard villa in Mt Eden, or a multi-level home on the North Shore, weak Wi-Fi is one of the most common tech complaints we see.

At Advanced Computers, we regularly diagnose slow or unstable wireless connections for Auckland homes and small businesses. In many cases, the fix is simpler — and more affordable — than people expect.

Here’s how to properly improve your Wi-Fi signal in 2026.

1. Start With Router Placement (It Matters More Than You Think)

Wi-Fi signals spread outward like light from a bulb. If your router is:

  • Hidden in a cupboard

  • Placed behind a TV

  • Sitting on the floor

  • Next to a microwave

  • Tucked inside a metal cabinet

You’re blocking your own signal.

Best practice:

  • Place your router in a central location

  • Elevate it off the floor

  • Keep it away from mirrors and large appliances

  • Avoid corners of the house

NZ building factor:

Many Auckland homes use GIB walls with metal bracing, concrete block construction, or foil insulation — all of which weaken wireless signals. If your router is at one end of the house, the signal may struggle to reach the other side.

2. Use the Right Wi-Fi Band (2.4GHz vs 5GHz vs 6GHz)

Older routers default to 2.4GHz, which:

  • Travels further

  • Is slower

  • Is heavily congested

In high-density areas like Newmarket, Ponsonby or the CBD, this band is often overcrowded.

Upgrade strategy:

  • Use 5GHz for faster speeds at moderate distances

  • Use 6GHz (Wi-Fi 6E/7) for ultra-fast speeds with minimal interference (if supported)

If you’re on Fibre 300, 500 or Hyperfibre but only seeing low speeds, you may be connected to the wrong band.

A Wi-Fi analyser app can help identify congested channels.

3. Stop Using Old Extenders — Move to Mesh Wi-Fi

Traditional Wi-Fi extenders often:

  • Cut your speed in half

  • Create multiple network names

  • Cause devices to drop when moving rooms

The modern solution: Mesh Wi-Fi systems

Mesh systems (such as TP-Link Deco or ASUS ZenWiFi) use multiple nodes to create one seamless network throughout your home.

Benefits:

  • No dead zones

  • Seamless roaming between rooms

  • Better performance in multi-storey homes

  • Stronger coverage for large properties

For many Auckland homes — especially villas and split-level houses — mesh is the most reliable long-term solution.

4. Your Laptop or PC Might Be the Problem

We frequently see customers upgrade to high-speed fibre, only to discover their older laptop can’t take advantage of it.

Signs your device is the bottleneck:

  • Your phone gets fast speeds but your laptop doesn’t

  • Your desktop struggles on 5GHz

  • Frequent disconnections on one device only

Possible fixes:

  • Install a Wi-Fi 6 or Wi-Fi 7 USB adapter

  • Upgrade an internal Wi-Fi card

  • Update network drivers

  • Remove malware affecting bandwidth

These are relatively quick upgrades that can significantly improve performance.

5. For Gaming & 4K Streaming, Use Ethernet

Wireless is convenient — but wired is still superior for:

  • Gaming PCs

  • PlayStation or Xbox

  • Smart TVs

  • Work-from-home desktop setups

A Cat6 Ethernet cable provides:

  • Lower latency

  • Higher stability

  • No signal interference

If running cables isn’t practical, Powerline adapters can send internet through your home’s electrical wiring — useful in older Auckland homes.

6. Check for Background Issues

Sometimes weak Wi-Fi isn’t a signal issue at all. It can be:

  • Malware using bandwidth

  • Too many startup applications

  • Outdated network drivers

  • Router firmware issues

  • ISP configuration problems

If speeds suddenly drop or devices behave erratically, it’s worth having the system checked.

When to Consider a Hardware Upgrade

Your router may need replacing if:

  • It’s more than 4–5 years old

  • It doesn’t support WPA3 security

  • It doesn’t support Wi-Fi 6 or newer

  • It struggles with multiple connected devices

Modern households often have 15–30 connected devices. Older routers simply weren’t designed for that load.
