How to improve Wi-Fi speed at home

Start by treating Wi-Fi as a local radio problem, not a street-speed problem. Move the hub, cut interference, pick the right band for each room, then retest after every change. Only chase a line upgrade once Ethernet proves the incoming service is the limit.

What matters most on Wi-Fi

Watch out forRouters trapped in cupboards, fish tanks, or behind TVs - common in UK terraces.
Best used forIterating placement before spending on new broadband tiers.
When to retestAfter each physical move or settings tweak, from the room you actually use.

Practical steps

  1. Place the router high, central, and off the floor with fewer walls and metal objects in the way.
  2. Separate the router from microwaves, baby monitors, and crowded Wi-Fi channels where you can.
  3. Use 5 GHz or Wi-Fi 6 for speed in the same room; fall back to 2.4 GHz only if distance demands it.
  4. Run Pulse before and after each change from the room that matters - bedroom desk, not just beside the router.
  5. If a dead zone remains, add a reputable mesh node or access point instead of boosting an already weak signal.

Typical home scenario

In a semi-detached house near Birmingham, the back bedroom gets half the Mbps of the lounge because the signal punches through one brick wall and a wardrobe. Moving the router one shelf higher - not buying faster fibre - is what lifted evening video calls.

Another angle

A flat in Glasgow’s West End runs fine until neighbours’ networks fill the 2.4 GHz band. Steering laptops to 5 GHz and reserving 2.4 GHz for simple IoT gadgets cleared the “mystery” slowdown.

How Pulse relates to this topic

Pulse is ideal for A/B testing Wi-Fi changes: same hour, same device, new router position. It measures download, latency, and jitter - not upload - so treat upload-heavy issues separately.

FAQ

Should I buy a faster broadband package to fix Wi-Fi?

Usually no. If Ethernet is fast and Wi-Fi is not, more Mbps from the street will not fix a bad wireless path.

Does the room matter?

Yes. A router shut in a hallway cupboard under the stairs is a classic UK bottleneck.

Is 5 GHz always better than 2.4 GHz?

5 GHz is often quicker at short range; 2.4 GHz reaches further through walls but with less throughput.

How do I know Wi-Fi was the problem?

Compare Pulse on Ethernet versus your usual spot. A big gap means work inside the home first.
