Why Is My Wifi Slower On My Tablet Than My Phone Diagnostic Checklist

If your tablet consistently delivers slower Wi-Fi performance than your phone—despite being in the same room, connected to the same network—it’s not just in your head. This discrepancy affects thousands of users daily, often leading to frustration during streaming, video calls, or online learning. The good news: most causes are diagnosable and fixable. Unlike a simple \"restart the router\" suggestion, this guide dives into technical, environmental, and device-specific factors that could be holding your tablet back. By following this structured diagnostic checklist, you’ll pinpoint the root cause and restore optimal performance.

1. Understand the Hardware Differences

Not all devices are built equally when it comes to wireless connectivity. Your phone may outperform your tablet due to internal hardware variances, even if both were released around the same time. Key differences include Wi-Fi antenna design, supported Wi-Fi standards (e.g., 802.11ac vs. 802.11n), and radio power output.

For example, many high-end smartphones support Wi-Fi 6 (802.11ax) and have multiple-input multiple-output (MIMO) antennas for better signal reception. In contrast, budget or older tablets might only support Wi-Fi 5 (802.11ac) or earlier, limiting maximum throughput and range. Additionally, tablets with larger bodies don’t always translate to better antennas—sometimes, internal component placement weakens signal capture.

Feature	High-End Phone	Mid-Range Tablet
Wi-Fi Standard	Wi-Fi 6 (802.11ax)	Wi-Fi 5 (802.11ac)
MIMO Support	2x2 or 4x4 MIMO	1x1 MIMO
Max Theoretical Speed	9.6 Gbps	1.3 Gbps
Antenna Quality	Optimized for grip and orientation	Less optimized; prone to hand blocking

Tip: Check your tablet’s specs under “Settings > About Device > Legal Information” or consult the manufacturer’s website to verify its Wi-Fi capabilities.

2. Conduct a Side-by-Side Speed Test

Before troubleshooting, confirm the issue with empirical data. Run speed tests simultaneously on both devices using the same app (e.g., Speedtest by Ookla or Fast.com). Ensure both devices are within 3 feet of each other and connected to the same Wi-Fi network (same band, ideally 5 GHz).

1. Close all background apps on both devices.
2. Move both devices close to the router.
3. Connect both to 5 GHz Wi-Fi (if available).
4. Run three consecutive speed tests on each device.
5. Average the download and upload results.

If the tablet consistently scores 30% or lower than the phone, the issue is confirmed. If results are similar, the original perception may stem from software lag or app optimization rather than actual network speed.

“We see a growing gap in real-world Wi-Fi performance between flagship phones and mid-tier tablets, primarily due to RF engineering trade-offs.” — Dr. Lena Torres, Senior Network Engineer at NetMetrics Lab

3. Analyze Wi-Fi Band and Signal Strength

Many tablets default to the 2.4 GHz band, which has longer range but significantly lower bandwidth and higher interference from microwaves, cordless phones, and neighboring networks. Meanwhile, modern phones automatically prefer 5 GHz when available, offering faster speeds and less congestion.

To check which band your tablet is using:

• On Android: Go to Settings > Network & Internet > Wi-Fi, tap the connected network, and look for frequency (2.4 GHz or 5 GHz).
• On iPad: Navigate to Settings > Wi-Fi, tap the info (i) icon next to the network. Scroll down to find “Frequency” listed in GHz.

If your tablet shows 2.4 GHz while your phone is on 5 GHz, that alone explains the speed difference. However, some tablets lack 5 GHz support entirely—especially older models or entry-level devices.

Tip: Manually forget the 2.4 GHz network and reconnect to ensure the tablet chooses the 5 GHz version if SSIDs are separated (e.g., “Home-WiFi-5G”).

4. Evaluate Interference and Environmental Factors

Physical environment plays a critical role. Tablets are often used lying flat on laps, beds, or tables—positions that can block internal antennas. The human body absorbs Wi-Fi signals, especially at 5 GHz frequencies. Holding a tablet in landscape mode may cover one or both antenna lines located along the edges.

In contrast, phones are typically held vertically, minimizing obstruction, and their compact size allows more consistent signal exposure.

Common sources of interference include:

• Thick walls or metal furniture between device and router
• Other electronic devices (Bluetooth speakers, baby monitors)
• Congested Wi-Fi channels in apartment buildings
• Router placement in basements or enclosed cabinets

Try repositioning the tablet upright or placing it on a stand during testing. Even a slight angle change can improve signal strength by several dBm.

Mini Case Study: Sarah’s Streaming Struggles

Sarah noticed her iPad frequently buffered during Netflix sessions, while her iPhone streamed flawlessly in the same living room. After checking settings, she found the iPad was stuck on 2.4 GHz despite 5 GHz availability. She renamed her 5 GHz network to “Home-5G” and manually connected the iPad. Buffering stopped immediately. Later, she realized that resting the iPad on a wool blanket was dampening the signal. Using a plastic stand improved stability further. Simple fixes resolved what seemed like a hardware limitation.

5. Perform a Full Diagnostic Checklist

Use this comprehensive checklist to methodically eliminate potential causes:

1. Verify Wi-Fi bands: Confirm both devices are on the same frequency (5 GHz preferred).
2. Check signal strength: Compare RSSI (Received Signal Strength Indicator) values; aim for -60 dBm or better.
3. Restart both devices: Clear temporary glitches in network stacks.
4. Forget and rejoin Wi-Fi: On the tablet, remove the network and reconnect to refresh IP and DNS settings.
5. Update firmware: Install the latest OS and router updates.
6. Test with another network: Visit a friend’s house or use a mobile hotspot to isolate home router issues.
7. Disable battery-saving modes: These can throttle Wi-Fi performance on tablets.
8. Check for background downloads: Apps like cloud backups or software updates consume bandwidth silently.
9. Inspect router QoS settings: Some routers deprioritize tablets in traffic shaping rules.
10. Factory reset (last resort): If all else fails, reset network settings or perform a full device reset.

6. Router and Network Configuration Issues

Your router may be contributing to the imbalance. Dual-band routers often use band steering to direct devices appropriately, but not all tablets respond well to these signals. Some routers assign older or less-capable devices to 2.4 GHz automatically, even if they support 5 GHz.

Log into your router’s admin panel (usually via 192.168.1.1 or 192.168.0.1) and review:

• Connected devices list: Identify whether the tablet appears on 2.4 GHz or 5 GHz.
• Band steering settings: Disable temporarily to manually control connections.
• Channel congestion: Use a tool like Wi-Fi Analyzer (Android) to detect crowded channels and switch to less busy ones.
• Firmware version: Outdated firmware can cause poor device management.

Consider enabling separate SSIDs for 2.4 GHz and 5 GHz networks. This gives you full control over which band each device uses.

7. Software and Background Activity

Tablets often run more background processes than phones—especially if used for media consumption, education, or productivity. Cloud sync services (Google Drive, iCloud), automatic app updates, and ad-heavy websites can eat up bandwidth unnoticed.

To assess:

• Go to Settings > Network & Internet > Data Usage (Android) or Settings > Cellular > Wi-Fi (iOS) to view per-app data consumption.
• Turn off auto-updates for apps and system software temporarily during testing.
• Enable Airplane Mode briefly, then disable it and reconnect to Wi-Fi to force a clean connection.

Also, consider browser efficiency. Some tablets use outdated or poorly optimized browsers that struggle with modern web standards, creating the illusion of slow internet.

8. Frequently Asked Questions

Can a tablet’s age really affect Wi-Fi speed?

Yes. Tablets older than four years likely support only Wi-Fi 4 (802.11n) or early Wi-Fi 5, lacking MU-MIMO, beamforming, and efficient spectrum use. Newer routers optimize for newer devices, leaving older hardware behind.

Why does my tablet disconnect more often than my phone?

This often stems from aggressive power-saving features. Tablets may turn off Wi-Fi radios during sleep to conserve battery. Adjust settings to keep Wi-Fi active during sleep or use “Always” mode in advanced Wi-Fi settings.

Does screen size impact Wi-Fi performance?

Indirectly. Larger screens require more power and generate more heat, potentially affecting radio stability. Also, bigger chassis can interfere with antenna placement and user grip, increasing signal blockage.

Final Steps: When to Upgrade or Replace

If diagnostics reveal your tablet lacks modern Wi-Fi standards or has persistent hardware limitations, consider upgrading. A new tablet with Wi-Fi 6/6E support will offer dramatically better performance, especially on updated networks. Alternatively, if your router is over five years old, replacing it with a Wi-Fi 6 model can improve fairness across all devices.

However, don’t rush to replace hardware prematurely. Many cases stem from misconfigurations or environmental factors easily corrected with awareness and adjustment.
