A calm, practical guide to speeding up your home internet, from router placement and Wi-Fi tweaks to spotting the limits of your current plan.
Most home internet slowdowns trace to one of four causes: a congested Wi-Fi channel, a router sitting in a bad spot, aging hardware, or a plan that genuinely cannot keep up. Before you pay for a faster tier, rule out the first three — they cost nothing and fix most real-world cases.
The fastest way to find out is to measure first, then work outward from the router.
Run a speed test for numbers to compare against. Use Ookla's Speedtest (speedtest.net or the app) or Netflix's fast.com, and run it twice: once on a device plugged into the router by Ethernet, and once on Wi-Fi where you actually use it.
The wired test shows what is arriving at your home; the Wi-Fi test shows what reaches your device after walls and interference take their cut. If the wired number roughly matches your plan (around 940 Mbps on a "1 Gig" plan is normal — that is protocol overhead, not a fault) but Wi-Fi is a fraction of it, the problem is Wi-Fi, not the plan. If even the wired number is far below what you pay for, the issue is the line, the modem, or the plan itself.
Test once during a quiet morning and again around 8 to 10 pm, when neighbourhood networks are busiest. A large evening drop points to congestion rather than a fault.
Raw megabits are not everything. A connection can test at 500 Mbps and still feel laggy on calls if it suffers from bufferbloat — latency that spikes under load. The free test at waveform.com/tools/bufferbloat grades this. If your latency jumps from around 20 ms idle to 200 ms or more, turning on Smart Queue Management (labelled SQM or QoS) in your router usually helps more than extra bandwidth.
Wi-Fi radiates outward and weakens through walls, floors, water, and metal. A router hidden in a cabinet, tucked behind the TV, or sitting on the floor in a corner is quietly throttling itself. Aim for a central, elevated, open spot — a shelf at head height in a central room beats a basement corner. Keep it a few feet from large metal objects, mirrors, and especially the microwave, which shares the 2.4 GHz band and can stall it while it runs.
Restart it, too. Unplug the router (and separate modem, if you have one) for 30 seconds, then wait two to three minutes for it to re-sync. This clears memory leaks and forces a fresh connection; doing it every few weeks beats waiting for a crisis.
Modern routers broadcast on more than one frequency band, and picking the right one is among the biggest free wins available.
If your router uses one name for all bands (band steering), it usually chooses well, and standing near it lets your device grab 5 or 6 GHz. If you keep getting stuck on the slow band, many routers let you split the names so you can join the faster one directly.
On 2.4 GHz, only channels 1, 6, and 11 do not overlap, so in an apartment block dozens of networks pile onto the same one and drag everyone down. Most routers auto-select, but you can force a clear channel under Wireless > Channel. A free scanner such as WiFi Analyzer on Android shows which are least crowded. On 5 GHz, width matters: 80 MHz is a solid balance, while 160 MHz is faster but more fragile in a congested building.
For anything that stays put and cannot stutter — a desktop, game console, smart TV, or work-from-home PC — a wired connection is the single biggest reliability upgrade. Ethernet sidesteps interference entirely and holds steady through busy evenings.
Use at least a Cat 5e cable; it carries full gigabit up to 100 m, and Cat 6 adds headroom for 2.5G and 10G plans. You need not wire the whole house — moving even one demanding device off Wi-Fi frees the airwaves for everything that stays wireless.
Cannot run a cable? Two decent workarounds:
For large or multi-floor homes, a mesh system such as eero, TP-Link Deco, or Google Nest Wifi is the cleaner fix. Place the nodes within solid range of each other, and if you can wire them together (wired backhaul), do it — it gives by far the steadiest result.
If you have done all of the above and it is still slow, look at age and limits.
Wi-Fi standards move quickly. Wi-Fi 5 (802.11ac) arrived in 2014, Wi-Fi 6 (802.11ax) in 2019, Wi-Fi 6E in 2021, and Wi-Fi 7 in 2024. A router more than six or seven years old — or an ISP gateway that was never swapped — can bottleneck a fast plan no matter where you put it. If you rent, ask your provider for a current model, or buy your own compatible unit to end the monthly rental fee.
Log into your router (often 192.168.1.1 or 192.168.0.1, or the vendor app) and check for firmware updates; these fix bugs, close security holes, and occasionally improve throughput. While you are there, confirm you are on WPA3, or WPA2 at the least — never WEP or an open network.
Your subscribed speed is a hard ceiling no tweak can raise. If four people stream 4K, game, and take calls at once on a 100 Mbps plan, you are simply out of headroom. Compare your wired test to the plan you pay for; a wide, consistent gap is a solid reason to call your provider to check the line or move up a tier.
Swapping your DNS resolver will not raise bandwidth, but it can make pages feel snappier by resolving addresses faster. Set Cloudflare (1.1.1.1), Google (8.8.8.8), or Quad9 (9.9.9.9) in your router's DNS settings so every device benefits at once.
Not directly, but it clears memory issues, drops stale connections, and can land you on a less crowded Wi-Fi channel when it reconnects. It helps most when speeds have gradually degraded over days. Needing to restart every single day points to a failing router or a line fault worth reporting.
If your current router is Wi-Fi 5 or older and you have a fast plan with many devices, yes — the newer standards handle congestion far better, which matters more than headline speed. If you have only a handful of devices on a sub-100 Mbps plan, a good Wi-Fi 5 router placed well is plenty, and the upgrade will not change much.
Evening is peak usage. If your wired speed holds but Wi-Fi sags at night, neighbouring networks are congesting your channel, so switch to a clearer one or move to 5 or 6 GHz. If even the wired speed drops, your local area may be oversubscribed, and that is one to raise with your provider.
Buying your own often means better hardware and an end to the monthly rental fee, which pays for itself within a year or two. Just confirm it is compatible with your provider and your plan's speed. If you would rather not configure anything, the ISP unit is fine — just make sure it is a current model, not a decade-old box.
