If your Wi-Fi crawls in the evening but flies during the day, you’re not imagining it. Here are the most common causes — and what actually fixes them.

1. Network congestion (the #1 cause)

Evenings are peak internet hours. Your whole neighbourhood streams at once, which can slow your internet provider’s local network. Test at different times; if it’s always slow at night specifically, congestion is likely.

2. Wi-Fi channel interference

Neighbouring routers crowd the same channels after work hours. Log into your router and switch to a less congested channel, or enable the 5 GHz / 6 GHz band, which is faster and less crowded than 2.4 GHz.

3. Too many devices at once

Smart TVs, phones, consoles, and smart-home gear all compete in the evening. Wi-Fi 6/6E routers handle many devices far better than older models.

4–9. Quick fixes to work through

  • Restart your router weekly — memory leaks and heat degrade performance.
  • Move the router central and elevated, away from walls, metal, and microwaves.
  • Update firmware — vendors ship performance and security fixes.
  • Check for background updates (console/PC downloads) hogging bandwidth.
  • Scan for dead spots — weak coverage looks like “slow” Wi-Fi. See how to fix Wi-Fi dead spots.
  • Consider your plan — if every device is slow at peak, you may have outgrown your speed tier.

Still slow after all that?

If coverage is the issue, a mesh upgrade often helps. Estimate what your home needs with our Wi-Fi Coverage Estimator, then see current routers on Amazon.

How to Fix Wi-Fi Dead Spots (Free Fixes First)

A Wi-Fi dead spot is a room or corner where the signal drops or disconnects. Before buying anything, work through these free fixes — then upgrade only if you still need to.

Free fixes to try first

  1. Reposition the router — central, elevated, and out in the open. Corners and closets kill range.
  2. Point antennas correctly — for multi-floor coverage, angle some horizontally.
  3. Switch bands/channels — 2.4 GHz travels further through walls; 5 GHz is faster at close range. Change to a less crowded channel.
  4. Remove interference — keep the router away from microwaves, cordless phones, and large metal objects.
  5. Update firmware and reboot.

If free fixes aren’t enough

  • Wi-Fi extender — cheapest option; fine for one stubborn room, but can halve speed.
  • Mesh system — the best fix for whole-home dead spots; nodes hand your devices off seamlessly.
  • Wired access point / powerline — most reliable if you can run Ethernet or use existing wiring.

How much hardware do you need?

Use our Wi-Fi Coverage Estimator to see whether a single router, a 2-node, or a 3-node mesh suits your home. Then compare mesh systems and extenders on Amazon.

Rule of thumb: one good router or access point reliably covers about 1,500 sq ft on a single level. Beyond that — or through thick walls and multiple floors — you’ll want additional nodes. Use the estimator below for your home, then read on for the reasoning.

What affects coverage

  • Square footage — the biggest factor.
  • Walls and construction — drywall is easy; brick, concrete, and metal cut range sharply.
  • Floors — signal weakens going up or down between levels.
  • Device count — many simultaneous devices favour Wi-Fi 6/6E hardware.

General guidance

Home size Typical setup
Up to ~1,500 sq ft, one floor Single quality router
1,500–3,000 sq ft or 2 floors 2-node mesh
3,000–5,500 sq ft 3-node mesh
5,500 sq ft+ or dense walls 3+ nodes or wired access points

Access point vs. mesh node

A mesh node connects wirelessly and is plug-and-play — best for most homes. A wired access point connects by Ethernet and is more reliable and higher-performance, but needs cabling. If you can run Ethernet, wired backhaul is the gold standard.

What Size Power Bank Do You Need? (By Device and Trip)

Disclosure: We may earn a commission from qualifying purchases through links on this page, at no extra cost to you. Learn more.

The right power bank size depends on what you’re charging and how long you’ll be away from an outlet. Here’s a simple way to choose without overpaying for capacity you’ll never use.

Match capacity to your need

Use case Recommended capacity Why
Topping up a phone during the day 5,000–10,000 mAh 1–2 phone charges, pocketable
All-day travel / one phone 10,000–20,000 mAh 2–5 charges, still airline-friendly
Multiple devices / weekend trip 20,000–26,800 mAh Phone + earbuds + tablet
Laptop / camping / off-grid 25,000 mAh+ with USB-C PD Higher wattage output needed

Don’t just look at mAh

  • Output wattage (USB-C PD): to fast-charge a phone you want 20 W+; for laptops, 60–100 W.
  • Real charges are lower than the label — expect roughly 70–85% efficiency. Our Power Bank Calculator shows the realistic number for your device.
  • Air travel: stay under 100 Wh (about 27,000 mAh) to avoid airline approval. See power banks on a plane.

Power Bank Calculator

Estimate how many full charges a power bank will give your device. Real-world results are lower than the raw mAh figures because of conversion losses.

Typical real-world efficiency is about 70–85%. Default 80%.

Disclosure: some links below are affiliate links. We may earn a commission from qualifying purchases at no extra cost to you. This never affects our recommendations.

Short answer: A 20,000 mAh power bank realistically recharges a typical smartphone 3 to 5 times — not the 6+ the raw numbers suggest. That’s because of conversion losses. Use the calculator below to get a number for your exact phone.

Why you don’t get the full capacity

Power banks store energy at 3.7 V but charge your phone at 5 V or higher. Converting voltage loses energy as heat, so real-world output is typically 60–85% of the label. Fast charging, a warm battery, and cable quality all reduce it further.

The math

Charges = (power bank mAh × efficiency) ÷ phone battery mAh.

For a 20,000 mAh bank at 80% efficiency charging a 3,200 mAh phone: (20,000 × 0.8) ÷ 3,200 = 5 full charges. A phone with a bigger 5,000 mAh battery would get about 3.2 charges from the same bank.

Real-world examples

Phone battery Approx. full charges from 20,000 mAh
3,000 mAh (compact phone) ~5.3
4,000 mAh (mid-size) ~4.0
5,000 mAh (large/flagship) ~3.2

Flying with it? A 20,000 mAh bank is about 74 Wh, so it’s fine in carry-on — see can you take a power bank on a plane.

Can You Take a Power Bank on a Plane? (2026 Rules)

Disclosure: We may earn a commission from qualifying purchases through links on this page, at no extra cost to you. Learn more.

Short answer: Yes — but a power bank must go in your carry-on bag, never checked luggage, because it contains a lithium-ion battery. Most consumer power banks are allowed without special approval, and the deciding factor is the battery’s watt-hour (Wh) rating, not its size.

The watt-hour rules (US TSA/FAA and most airlines)

  • Under 100 Wh — allowed in carry-on, generally no airline approval needed. This covers almost every phone-charging power bank.
  • 100–160 Wh — allowed with airline approval, usually a maximum of two spares.
  • Over 160 Wh — not permitted on passenger aircraft.

How to convert mAh to Wh

Power banks are labelled in mAh, but airlines care about Wh. The formula is:

Wh = (mAh ÷ 1000) × battery voltage (lithium cells are 3.7 V).

So a common 20,000 mAh power bank is (20 × 3.7) = 74 Wh — comfortably under the 100 Wh limit. Even a large 26,800 mAh bank is about 99 Wh, still under the cap. Many power banks now print the Wh rating on the case.

Quick reference

Capacity Approx. Wh Allowed?
10,000 mAh 37 Wh Yes, carry-on
20,000 mAh 74 Wh Yes, carry-on
27,000 mAh ~100 Wh Yes / borderline — check
Over ~43,000 mAh >160 Wh No

Practical tips

  • Keep power banks in your carry-on and, ideally, in a pouch so the terminals can’t short against keys or coins.
  • Rules are set by aviation authorities and individual airlines and can change — confirm with your airline and the TSA/your national authority before flying, especially for international trips.
  • Not sure how many charges your bank actually delivers on a trip? Use our Power Bank Calculator to plan.
