Step 1: Run a Speed Test First

  1. 1

    Test at fast.com or speedtest.net

    Test on a device connected via ethernet cable directly to the router (not WiFi). Compare the result to your plan speed. If it matches — the problem is WiFi or the device. If much lower — the problem is the router, modem or your ISP.

Quick Fixes

  1. 2

    Restart your router and modem

    Unplug both from power. Wait 30 full seconds. Plug the modem in first, wait 60 seconds, then plug in the router. Wait 2 more minutes. This fixes most common speed issues by clearing memory and refreshing the ISP connection.

  2. 3

    Move closer to the router

    WiFi speed drops significantly with distance and through walls. Test while standing next to the router. If fast there but slow elsewhere, it is a coverage issue, not an ISP issue.

  3. 4

    Check who is connected to your WiFi

    Log into your router admin page (192.168.0.1) and check connected devices. Unrecognised devices using your WiFi will slow everyone down. Change your WiFi password if you find unknown connections.

  4. 5

    Change WiFi channel

    Log into router admin → Wireless settings → WiFi channel. Try channels 1, 6 or 11 for 2.4GHz. In crowded areas with many routers, channel congestion slows your connection.

  5. 6

    Check background activity on your devices

    Windows Update, cloud backups (iCloud, Dropbox) and streaming on other devices all compete for bandwidth. Check Task Manager (Windows) or Activity Monitor (Mac) Network tab to see what is using your connection.

When to call your ISPIf speed is consistently below your plan speed even on ethernet directly to the modem after a restart, this is an ISP problem. Call with your speed test results as evidence. Australian ISPs must meet minimum broadband standards.

Frequently Asked Questions

Network congestion. Many ISPs share bandwidth between households in local areas. Peak hours (6–11pm) cause slowdowns as everyone streams at once. Report it to your ISP with speed test results taken at peak vs off-peak times — ISPs can prioritise or upgrade local infrastructure in congested areas.
Yes — VPNs add encryption overhead and route traffic via additional servers, typically reducing speed 10–30%. Disconnect your VPN and retest to check if it is the cause of your slowdown.
