FAQs
Can I use different brands of access points in my network?
You can, and basic connectivity will work, but it is not recommended. Access points from one manufacturer share a controller, apply the same settings across every unit and support fast roaming between each other, so devices hand off cleanly as you move. Mixed brands mean separate management, inconsistent settings and slower or failed handoffs. If you already own mixed equipment, keep one brand for the main coverage and retire the rest as budget allows.
How many access points do I need?
It depends on the size and layout of the space, how many devices connect at once and what the walls are made of. A rough starting point in an open office is one access point for every 1,500 to 2,000 square feet, but concrete, glass and dense seating change that quickly. A site survey that measures actual signal strength is the only reliable way to decide, and it usually saves money compared with guessing high.
Should I use a mesh system or wired access points?
Wired access points give better stability and speed because each unit has its own full speed cable back to the switch, and power over Ethernet means no outlet is needed on the ceiling. Mesh systems are easier to install where cabling is impossible, but every wireless hop shares airtime with the clients and performance falls with distance. For a home, mesh may be enough; for a business, cabled access points are the dependable choice.
How do I ensure seamless roaming between access points?
Give every access point the same network name and password, enable the fast roaming standards your equipment supports, and place the units so their coverage overlaps just enough for a device to see the next one before the current signal fades. Keep neighbouring access points on different channels and avoid setting transmit power too high, which makes devices cling to a distant unit. Then walk the space on a call and confirm the handoffs.
What is the best way to test my WiFi network?
Use a WiFi analyser app on a laptop or phone to check signal strength and channel overlap in each area, and run speed tests at the same points to see real throughput rather than signal bars. Test at busy times as well as quiet ones, and test while moving between access points on a video call, because roaming problems only show up in motion. Record the results so you can compare after any changes.
In an office, clinic, hotel or warehouse the same steps happen at a larger scale and with less room for trial and error. We survey the building first, so access point positions come from measured coverage rather than guesswork, then run a category cable to each mark and power every unit from the switch. Our business Wi-Fi setup configures the access points as one managed system with staff, guest and device networks kept apart, and our network cabling and infrastructure work makes sure the wired side can carry everything the radios collect. The final walk-through with a laptop confirms roaming actually works where people move.
More questions
Do all my access points need to be on the same Wi-Fi channel?
No, and they should not be. Every access point broadcasts the same network name so devices can roam, but neighbouring units should sit on different channels so they do not compete for the same airtime. On the 2.4 GHz band only a few channels avoid overlapping each other, which is why it fills up quickly. The 5 GHz band offers many more, and a controller or a careful manual plan spreads the access points across them.
Can I connect one access point to another with an Ethernet cable?
Some access points have a second port that passes the network through to another device, and it works for a printer or a desk. Chaining access points that way is best avoided: each hop shares one uplink, a fault in the first unit takes down everything behind it, and few units pass through enough power to run a second access point. Run each access point on its own cable back to the switch, which is also far easier to troubleshoot.
How much should the coverage from access points overlap?
Enough that a device walking away from one access point can already see the next one at a usable strength before the first fades, and no more. Too little overlap leaves gaps in corridors and stairwells where calls drop; too much overlap on the same channel means access points hearing and interfering with each other. A site survey measures this directly, and adjusting transmit power after installation is how the balance is tuned.
Why is my Wi-Fi still slow with multiple access points?
Look at what feeds them. Mesh units that connect to each other wirelessly share their airtime for backhaul, so speed falls with each hop. A cabled access point can be throttled by an old switch port, a poor cable or an internet connection that was already the bottleneck. Too many devices crowded onto the 2.4 GHz band, or channels set too wide for a busy space, cause the same complaint. Fix the wired path first, then tune the radios.
