Choose for your household’s busiest moments, not just the biggest number. Use the same assumptions for every offer and verify the latest terms directly.
Think in simultaneous activities
Consider what happens when everyone is online at once: video calls, streaming, gaming and large downloads. A single user checking email has different needs from several people working and studying at home. Write down the busiest realistic combination.
Look beyond download speed
Upload performance matters for sending files and video calls. Latency and connection stability affect interactive tasks. Wi-Fi coverage can become the bottleneck even when the incoming connection is fast, so diagnose the weak point before buying a faster package.
Distinguish the line from your Wi-Fi
A wired connection near the router can perform differently from a phone two floors away. Router placement, walls and interference can affect indoor performance. Compare a wired test with a Wi-Fi test before concluding the broadband line is too slow.
Check the specific offer
Review the contract’s speed information and the technology available at your address. Fibre, cable and mobile broadband can have different characteristics. For mobile broadband, reception inside your home matters.
Pay for a useful improvement
Ask which task the upgrade would improve and how often that task occurs. If your main problem is coverage in a back room, a more expensive incoming speed may leave it unresolved. Compare equipment options and the full contract price alongside the advertised speed.
