Why Is My Internet So Slow on My Phone?
Why Is My Internet Slow on My Phone? Here’s What to Check and Fix
TLDR
If your phone’s internet is slow, you already know how frustrating it is.
Slow phone internet is a common problem for Australian homes and small business users. The cause is usually a mix of hardware limitations, Wi-Fi setup issues and environmental factors.
Typical culprits include router placement, electronic interference, network congestion, VPN usage, cache build-up and line faults.
Quick wins can include moving your router, rebooting it, clearing your cache or switching plans or providers. Businesses can also call professional IT support services like Affinity MSP for expert help.
In this article, we’ll walk through simple checks and steps you can try if your phone is running slow on Wi-Fi before seeking support.
Router Location Matters
If your phone’s internet is slow, start with the most common issue: router placement.
The further your phone is from the router, the weaker the signal becomes. Walls, doors and dense materials can significantly reduce Wi-Fi strength.
At Affinity MSP, we recommend placing your router in a central location, elevated off the floor and free from obstructions. Avoid cupboards, corners, floors and metal-heavy areas to get the strongest and most consistent signal throughout your space.
Electronic Interference and Wi-Fi Frequency
If your phone is slow on Wi-Fi, interference may be the issue.
Common sources include microwaves, cordless phones, baby monitors and Bluetooth devices. These can disrupt Wi-Fi signals, especially on older networks.
It’s also important to check which frequency band you’re using.
- 2.4 GHz travels further but is slower and more crowded
- 5 GHz is faster but has a shorter range
If your router and phone support dual-band Wi-Fi, try connecting to 5 GHz when you’re close to the router for better performance.
Network Congestion and Devices Sharing Bandwidth
When everyone is online at the same time, speeds drop. Think of it like peak-hour traffic.
Evening streaming, gaming and video calls often cause congestion, particularly on home broadband connections when everyone returns from work or school.
A quick fix is disconnecting unused devices. Longer term, consider upgrading your internet plan or investing in a higher-quality router that can handle more devices simultaneously.
Device Performance and VPN Usage
If your phone is running slow on Wi-Fi, the device itself could be the bottleneck.
Older phones and outdated operating systems struggle to keep up with modern internet demands. Start with basic device hygiene:
- Restart your phone
- Update the operating system
- Close unused or heavy apps
If you’re using a VPN, that can also slow things down. Test your speed with the VPN disabled or switch servers to see if performance improves.
Clear Your Browser Cache
Your browser cache stores website data to load pages faster, but over time it can have the opposite effect.
When the cache builds up, pages may load slowly or behave unpredictably. Clearing your cache occasionally is a simple maintenance habit that can noticeably improve performance.
Consider Professional Help for Persistent Issues
When customers tell us, “My phone’s Wi-Fi speed is slow,” the first thing we ask is whether basic DIY fixes have been tried.
If problems persist across multiple devices, or you’re experiencing frequent dropouts with no obvious cause, there may be deeper issues at play. These can include firmware faults, wiring problems or broader network issues.
You don’t need to troubleshoot this alone. Affinity MSP provides professional diagnosis, optimisation and ongoing IT support, particularly for businesses that rely on fast, reliable connectivity to operate efficiently.
Summary Table: Common Causes and Fixes
If your phone is running slow on Wi-Fi, here’s a quick summary of likely causes and what to try.
| Cause | Fix |
|---|---|
| Router too far or blocked | Move router to a central location, away from walls and obstacles |
| Wi-Fi interference | Switch to the 5 GHz band, reduce nearby electronics |
| Too many connected devices | Disconnect unused devices, upgrade bandwidth plan |

FAQs
When you’re dealing with low speeds and wondering how to fix slow Wi-Fi on a phone, these FAQs may help.
Why is my phone’s internet slower than other devices on the same Wi-Fi?
It could be the phone itself. Different devices have different hardware capabilities, Wi-Fi antennas and software limitations, especially older models.
How does router placement affect my phone’s Wi-Fi speed?
Router placement is critical. If your router is too far away, blocked by walls or placed low to the ground, your phone may struggle to maintain a strong signal. Moving it to a central, elevated position can make a noticeable difference.
What causes Wi-Fi interference and how do I fix it?
Interference often comes from household electronics operating on the 2.4 GHz band. Switching to 5 GHz, if supported, usually reduces interference and improves speed.
Can multiple devices slow down my phone’s internet?
Yes. Multiple devices competing for bandwidth will slow down your connection. Disconnect unused devices or upgrade your internet plan to improve overall performance.
Does using a VPN affect my phone’s internet speed?
Yes. VPNs can slow down traffic, especially if servers are overloaded. If your phone is slow on Wi-Fi, try disabling the VPN or switching servers to test performance.
