It’s a common frustration: you’re browsing on your phone with lightning-fast load times, but when you switch to your tablet—same room, same network—the experience feels sluggish. Pages take longer to load, videos buffer unexpectedly, and downloads crawl. You're not imagining it. Many users report noticeably slower WiFi speeds on tablets compared to smartphones, even under identical conditions. The reasons aren't always obvious, but they’re often rooted in hardware limitations, software inefficiencies, or overlooked environmental factors. Understanding these differences can help you diagnose and fix the real cause behind your tablet's lag.
Hardware Differences Between Tablets and Phones
At first glance, tablets and phones may seem like equally capable devices. However, their internal components—especially those related to wireless connectivity—can vary significantly, even within the same brand or product line.
One of the most critical components affecting WiFi speed is the wireless network adapter. This chip handles all communication between your device and the router. Older or budget-friendly tablets often come equipped with outdated WiFi standards such as 802.11n (WiFi 4), while modern smartphones typically support at least 802.11ac (WiFi 5) or even 802.11ax (WiFi 6). This single difference can result in dramatically different throughput speeds, especially in high-bandwidth scenarios like streaming HD video or downloading large files.
Another factor is antenna design. Smartphones are engineered for maximum signal efficiency in mobile environments. They often include multiple antennas for MIMO (Multiple Input, Multiple Output), which improves data transfer rates and signal stability. Tablets, particularly older models, may have fewer or less optimally placed antennas, reducing their ability to maintain strong connections—even when physically close to the router.
Software and Firmware Limitations
Beyond hardware, software plays a crucial role in how efficiently a device uses available bandwidth. Operating system updates, background processes, and firmware bugs can all impact perceived network performance.
Tablets, especially those no longer actively supported by manufacturers, may run outdated versions of Android or iOS that lack optimizations for modern routers. For example, newer routers use advanced features like MU-MIMO (Multi-User MIMO) and beamforming, which direct signals more efficiently to connected devices. If your tablet’s OS doesn’t support these technologies, it won’t benefit from them—even if the hardware technically allows it.
Additionally, some tablets suffer from poor power management settings that throttle CPU or radio performance to conserve battery. While this extends usage time, it can also reduce network responsiveness. In contrast, smartphones are often tuned more aggressively for performance due to their primary role in communication and real-time apps.
Background app activity also contributes. A tablet used primarily for media consumption might have multiple streaming apps syncing in the background, consuming bandwidth without user awareness. Meanwhile, a smartphone might be optimized to limit such behavior unless actively in use.
“Many older tablets were designed during an era when home networks rarely exceeded 50 Mbps. Today’s gigabit connections expose their limitations.” — Rajiv Mehta, Network Infrastructure Analyst at NetSignal Labs
Environmental and Network Factors
Even with identical hardware and software, small changes in environment can lead to significant performance differences. How and where you use your tablet versus your phone matters more than you might think.
For instance, many people hold phones closer to their bodies or use them while moving around the house. Tablets, however, are often placed flat on tables, laps, or stands—positions that can block antenna reception. If the tablet’s internal antenna is located along the top edge, placing it flat on a wooden table could partially obstruct the signal path, leading to weaker reception and lower speeds.
Distance from the router isn’t the only variable. Interference from other electronic devices—microwaves, cordless phones, Bluetooth gadgets—can disrupt the 2.4 GHz band, which both devices likely use. But because tablets may have less sophisticated interference filtering, they’re more prone to slowdowns in congested environments.
Moreover, dual-band routers broadcast on both 2.4 GHz and 5 GHz frequencies. The 5 GHz band offers faster speeds but shorter range. Your phone might automatically switch to 5 GHz when near the router, while your tablet could remain stuck on 2.4 GHz due to compatibility issues or misconfigured settings.
Do’s and Don’ts: Optimizing Device Placement
| Do | Don’t |
|---|---|
| Place the tablet vertically or on a stand to avoid blocking antennas | Lay the tablet flat on metal or dense surfaces |
| Keep both devices within 10–15 feet of the router for fair comparison | Test one device in the kitchen and the other in the bedroom |
| Ensure line-of-sight between device and router when possible | Place the router behind a TV or inside a cabinet |
Step-by-Step Diagnosis Guide
If you're experiencing slower WiFi on your tablet, follow this structured approach to identify and resolve the root cause:
- Verify both devices are on the same network
Ensure neither is using cellular data. Go to Settings > WiFi and confirm both are connected to the same SSID. - Run a speed test simultaneously
Use a reliable app like Speedtest by Ookla on both devices at the same time. Perform tests in the same location to eliminate environmental variables. - Check WiFi standards supported
Look up your tablet and phone model specifications online. Confirm whether one supports newer WiFi standards (e.g., WiFi 5/6) and the other does not. - Switch to 5 GHz manually (if available)
If your router supports 5 GHz, ensure your tablet is connected to it. Some older tablets don’t auto-switch bands; you may need to forget the 2.4 GHz network and reconnect specifically to the 5 GHz version. - Restart both devices and router
A simple reboot clears temporary glitches, resets network stacks, and re-establishes optimal connections. - Forget and rejoin the WiFi network
On the tablet, go to WiFi settings, select your network, and choose “Forget.” Then reconnect by entering the password again. This refreshes DHCP and authentication settings. - Update operating system and firmware
Check for pending updates on the tablet. Outdated software can introduce bugs that degrade network performance. - Test with another high-demand device
Compare the tablet’s speed to a laptop or newer smartphone. If all non-phone devices perform poorly, the issue may lie with the tablet’s age or category rather than the network.
Real-World Example: Sarah’s Streaming Struggles
Sarah noticed her iPad would constantly buffer during evening Netflix sessions, while her iPhone played the same shows without issue. Both devices were in the living room, connected to the same WiFi network. Frustrated, she assumed her internet plan was inadequate.
After running side-by-side speed tests, she discovered her iPhone averaged 85 Mbps, while the iPad barely reached 18 Mbps. A quick search revealed her iPad model only supported WiFi 4 (802.11n), whereas her iPhone supported WiFi 6. Her router, upgraded two years prior, was broadcasting on both 2.4 GHz and 5 GHz—but the iPad wasn’t properly connecting to the faster band.
She manually disconnected the iPad from the 2.4 GHz network and joined the 5 GHz version. Speed immediately improved to 63 Mbps. She also adjusted the placement of the iPad, propping it up on a stand instead of laying it flat on the couch. These two changes resolved the buffering issue entirely.
Sarah’s case illustrates how a combination of outdated hardware and suboptimal setup can create misleading performance gaps—even when everything appears to be functioning normally.

Frequently Asked Questions
Can a factory reset improve my tablet’s WiFi speed?
Yes, in some cases. A factory reset clears corrupted network configurations, bloatware, and misbehaving apps that may interfere with connectivity. However, this should be a last resort after trying simpler fixes like forgetting the network or updating software. Be sure to back up your data before proceeding.
Does screen size affect WiFi performance?
No, screen size itself has no direct impact on WiFi speed. However, larger devices like tablets may have different internal layouts that affect antenna placement and signal reception. The design trade-offs in larger form factors can indirectly influence wireless performance.
Why does my tablet disconnect from WiFi randomly?
Random disconnections are often caused by power-saving settings that turn off WiFi during inactivity. Disable “Adaptive WiFi” or “Intelligent Wi-Fi” in your tablet’s settings. Also, check if the router assigns stable IP addresses via DHCP reservation, as IP conflicts can cause dropouts.
