Phone Wi-Fi Slower Than Your Laptop? Run This Comparison First

Your phone may be using a slower Wi-Fi band, receiving a weaker signal, or supporting a lower wireless data rate than your laptop. The comparison may also be unfair: different test servers, background downloads or a wired laptop connection can change the result.

Start by testing both devices in the same spot, on the same Wi-Fi band, one at a time. A phone’s speed test measures the connection available to that phone—not the maximum capacity of your home network. Ookla confirms that device radio capabilities, MIMO stream handling, browsers and test servers can all produce different results.

Run a fair phone-versus-laptop test

Before changing router settings:

1. Put both devices about 2–3 metres from the router, with no wall or furniture between them. This follows TP-Link’s near-router testing guidance.
2. Make sure both are using Wi-Fi. Disconnect the laptop’s Ethernet cable or wired dock connection. Temporarily turn off mobile data on the phone so the test cannot use cellular instead.
3. Check the actual band and access point. Look in the device’s connection details or the router’s connected-device list, if available. The same network name does not prove both devices are on the same band or mesh node.
4. Pause downloads, photo backups, streaming and updates, including heavy activity on other devices.
5. Use the same speed-test service and manually select the same server, where supported. Prefer the service’s app on both devices if it offers one; do not treat an app-versus-browser comparison as identical.
6. Alternate three tests on each device, rather than running them simultaneously. Record the middle result, plus the range, for download and upload speed.

If the ranges overlap substantially, the apparent gap may be normal test variation; repeat the comparison before diagnosing a device limit.

Repeat the comparison in the room where the phone feels slow. Keep location, band and test method consistent within each pair. For a fuller internet-versus-Wi-Fi check, use our three-test diagnostic method: wired, Wi-Fi near the router, and Wi-Fi in the problem location.

What can make the phone slower?

It is connected to a different band

A phone on 2.4 GHz and a laptop on 5 GHz are not using equivalent wireless connections. Try both on 5 GHz near the router if they support it. Test 6 GHz only if both devices and the router support that band and it is available in your region.

Channel width matters too. Wider channels can carry more data, but they are more susceptible to interference. Apple recommends 20 MHz on 2.4 GHz and Auto or all supported widths on 5 GHz and 6 GHz. Do not force 40 MHz on a crowded 2.4 GHz network just to chase a higher test result.

If the phone improves substantially after joining the same band as the laptop, the original gap was at least partly a connection-selection issue—not evidence that the phone needs replacing.

The devices have different Wi-Fi capabilities

Compare the specifications for your exact phone and laptop adapter:

• Wi-Fi generation and supported bands
• Maximum channel width
• Number of spatial streams, sometimes described as 1×1 or 2×2 MIMO

More spatial streams and wider supported channels can increase throughput, as explained in Apple’s Wi-Fi specification definitions. Both the router and client must support the feature being used. Even on the same band, the devices may use different channel widths or numbers of streams.

A newer laptop may therefore outperform an older phone. But phones are not inherently slower: a well-equipped phone can outperform a laptop with an older adapter.

Also, a displayed link speed or PHY rate is not your internet download speed. It describes the wireless link; the internet test includes other potential bottlenecks along the path.

Coverage affects the devices differently

Radio quality and antenna performance vary between devices. One may maintain a better connection through walls than the other. Apple’s roaming guidance notes that antennas vary by model and devices can perceive different coverage boundaries. If the gap largely disappears near the router but returns in another room, investigate coverage before assuming a fixed hardware limit.

Check whether the phone is joining a different mesh node. Reconnect its Wi-Fi in the problem room, check which node it joins and repeat the test; reconnecting does not guarantee a different node. Moving the router or access point is worth testing before buying equipment; an additional access point or mesh node is most relevant when the results point to a location-specific problem.

Software or router rules affect only the phone

Restart the phone and install available system updates. Check whether it has a VPN, filtering app or security app that the laptop does not use. On a trusted home network, temporarily pause an optional VPN or filter and retest, then restore it. Do not alter workplace-managed settings without permission. Apple recommends checking VPN and third-party security software when diagnosing device-specific connectivity problems.

In the router, look for a bandwidth limit, parental-control profile or priority rule assigned to the phone. TP-Link identifies QoS and parental controls as possible contributors to reduced speeds. Change one setting at a time and retest rather than disabling everything permanently.

Read the pattern, not just the biggest number

These are illustrative results, not expected speeds:

Repeatable result	Next step
Near router: laptop 500 Mbps, phone 120 Mbps, same band	Check phone specifications, test method, software and device-specific router rules.
Near router: both 400 Mbps; back room: laptop 200 Mbps, phone 40 Mbps	Investigate coverage, band selection and mesh-node association.
Wired laptop and both Wi-Fi devices all around 90 Mbps	Investigate the shared path, including the plan, router limits and Ethernet links; the phone is not uniquely slow.

If calls or games are the problem, also compare upload speed, latency, jitter and loaded latency. Loaded latency measures round-trip delay while the connection is busy; jitter measures variation in delay. Cloudflare explains why these metrics can matter more to calls and games than peak throughput.

A faster internet plan is not the first fix for a phone-only slowdown. Establish whether the gap follows the device, the room or the test setup before spending money.
