With remote work and smart homes growing in popularity, multiple devices—phones, laptops, TVs, smart speakers, security cameras and more—are connected to a single broadband network. But, does having more devices connected to a network lead to a drop in internet speed? The simple answer is, yes, it can, however, there are some simple hacks to ensuring good broadband speeds.
How Broadband Speed Works
Broadband speed is the maximum data transfer rate through an internet connection. The higher the speed, the more data can travel simultaneously. Think of it as a highway with more and wider lanes. When more cars try to use narrow lanes, traffic slows down. The same logic applies to broadband speed. When too many devices try to use the same connection, the available speed gets lower.
The Function of Bandwidth Distribution
Your broadband plan comes with a certain bandwidth limit. No matter how many devices are connected, the total serviceable speed won’t be reduced, it will only be shared. For instance, a 100 Mbps plan will have the total speed of 100 Mbps no matter how many devices are connected. The task performed on each device will determine the rate of deceleration of the internet speed.
Effects of Idle Devices
Idle devices connected to Wi-Fi usually don’t slow your internet significantly, but background apps and updates can. Smartphones often sync data, download software updates or back up photos without you realising, which can quietly consume bandwidth.
The Impact of Wi-Fi vs. Wired Connections
Ethernet connections will be faster and more reliable, making any wired connections a priority for busy homes or small businesses. Wi-Fi connections will have a greater slowdown experienced from multiple devices due to distance, signal congestion and a range of any other interference.
How Many Devices Is “Too Many”?
There is no explicit answer to this question, but most standard home broadband packages will be sufficient for anywhere between 10-15 devices. Anything above that, especially if more than one user has a high demand for bandwidth, might warrant an upgrade.
Ways to Avoid Drops in Speed
- If there are heavy users or many devices in your household, consider upgrading your broadband plan.
- Use dual-band or tri-band routers to distribute devices on separate frequency channels.
- Use QoS settings to prioritise bandwidth for video calls or gaming and lower the bandwidth for other activities.
- Minimise background activities like automatic updates or syncing to save bandwidth during peak hours.
- For large homes, consider a mesh Wi-Fi system to cover dead zones and avoid connectivity issues.
Frequently Asked Questions
Below we have answered some of the most commonly asked questions about how multiple-devices on your broadband connection work:
Does broadband speed drop if I’m only browsing on multiple devices?
Light activities like browsing or checking emails use very little bandwidth, so most households won’t notice a slowdown unless many devices are streaming or gaming at the same time.
Why does video streaming cause such big slowdowns?
HD and 4K video streaming uses big bandwidth and multiple streams can quickly consume your total available bandwidth.
Can upgrading my router fix the issue?
A dual-band or tri-band modern router will improve traffic distribution to an extent, but if the plan is slow, a newer router won’t help much.
Do smart home devices slow down broadband?
Smart devices such as light bulbs or thermostats use very little data, however, with a large amount of these smart devices connection, it can lead to network congestion (especially if they are communicating with cloud servers on a constant basis).
Should businesses worry about device overload more than homes?
Yes. Offices and call centres typically connect dozens or hundreds of devices simultaneously. The lack of sufficient broadband or business-grade broadband, will result in a rapid decline in performance.
