Describe the symptom precisely
“The Wi-Fi is slow” can describe several different faults. Does the device disconnect, stay connected without internet, pause during calls or only struggle with one application? Does it happen everywhere, in one room or at a particular time?
Record a few examples with the location, device and time of day. This helps avoid replacing equipment before the underlying problem is understood. Do not include passwords or sensitive business data in screenshots sent with an enquiry.
Coverage and placement
A router tucked into a communications cabinet may be convenient for cabling but poorly located for wireless coverage. Walls, shelving and other obstacles can reduce the usefulness of a signal in adjoining spaces.
Walking closer to an access point can be a helpful observation, but it is not a full test. Document the rooms where people actually work and assess whether the current placement was designed for those rooms.
Capacity and interference
Problems that appear when the office is busy may involve radio capacity or competing channel use. Meeting rooms can be particularly demanding because many devices are active in a small area.
More access points do not automatically mean better performance. Their placement and configuration need to work together. Changes should be assessed against the symptoms rather than applied as a list of “best settings” copied from another site.
The internet and wired network
Wireless performance is only one link in the connection. Internet capacity, gateway limitations, switch links and cabling can also constrain the result. Ubiquiti notes that an internet-plan speed does not guarantee the same speed over Wi-Fi.
Compare like-for-like observations and involve the appropriate provider. If wired and wireless devices both lose internet at the same time, that is useful evidence that the wireless radio may not be the only issue.
- Are wired devices affected at the same time?
- Does the issue affect all applications or only one?
- Is it limited to one device model?
- Did it begin after a layout or equipment change?
- Do problems follow a regular busy period?
Device behaviour and roaming
Different client devices have different capabilities. Drivers, power-saving behaviour and roaming decisions can affect the experience. Test with representative business devices rather than assuming a single phone describes the whole network.
An upgrade should respond to the evidence. Sometimes the useful change is access point placement or configuration; other sites need new cabling, more capacity or a targeted equipment replacement. A recorded baseline makes the outcome easier to assess.
