For a café, clinic, or boarding house whose network involves more than one router, calling an installer often makes more sense than doing it yourself.
The trouble is that quality varies enormously, and the difference only shows months later, when something needs changing and nobody knows how the setup was built.
One question that separates them
Ask this first: do you carry out a site survey before quoting?
A "yes" means they understand that wall materials, available cable routes, and desk positions matter far more than floor area. An answer that quotes a figure straight down the phone means they're selling hardware, not solving a problem.
Quotes without a survey almost always miss, in either direction. Missing low is worse, because the shortfall only appears once work is underway.
Six questions before signing
How many access points, and why that number?
A good answer gives reasons, room shape, wall materials, simultaneous visitors. "To be safe" or "that's standard" means it hasn't been calculated. The method is in the venue Wi-Fi capacity guide.
Is the guest network separated from operations?
If the quote doesn't mention it, ask. The till and CCTV on the same network as visitors is an unnecessary risk, the guide to separating a guest network.
Who holds panel access once it's finished?
The right answer is you. An installer withholding the admin password means calling them for something as small as changing the Wi-Fi password.
What's handed over when the work is done?
Ask for configuration documentation, an access point layout plan, and a list of fixed IP addresses. Without those, another technician starts from scratch.
Is the equipment certified?
Transmitting equipment sold here should be certified, and that also determines its official warranty , the guide to telecommunications equipment certification.
What happens after the warranty period?
Including whether there's a call-out fee and what the response time is. This is the most commonly unspoken item and the most common source of dispute.
Reading a quote
A careful quote separates three things. One that merges them into a single figure makes comparison difficult.
| Item | What should be visible |
|---|---|
| Hardware | Brand and model, not just "access point" |
| Materials | Cable length, type, connectors, conduit |
| Labour | Installation, configuration, testing |
| Beyond that | Building work where applicable |
Note the second row. Cable type is rarely stated, yet the difference between solid copper and copper-clad aluminium matters a great deal, especially with PoE. The reasons are in the guide to choosing LAN cable.
The last row is the item that most often blows a budget. Chasing walls and restoring ceilings can match the hardware cost, details in the guide to guest Wi-Fi costs for businesses.
Warning signs
- A figure produced without seeing the site. Already discussed, and the most decisive.
- Refusing to name the brand and model. Usually means hardware will be chosen later based on whatever's cheapest at the time.
- Promising implausible coverage. One access point for an entire three-storey building isn't something that can be promised, the guide to Wi-Fi signal boosters.
- Unwillingness to hand over the admin password. This locks you to one party.
- No documentation in the scope of work. It means future maintenance will be expensive, whoever does it.
Checks at handover
Don't sign off before testing yourself. Five checks are enough:
- Walk through every room while playing a video. Any drop-out point will show immediately.
- Test from a guest device whether it can reach the till computer. If it can, the separation isn't right.
- Run a speed test over cable and compare with your subscription, the internet speed test guide.
- Open the management panel yourself using the password handed over.
- Ask them to explain how to change the Wi-Fi password, then try it yourself, the guide to changing your Wi-Fi password.
Test number two is the one that fails most often. Many neat-looking installations turn out to put every device on one flat network. Checking takes a minute, and fixing it is far cheaper before final payment.
When doing it yourself makes more sense
Not every place needs an installer. If your situation looks like this, doing it yourself is usually fine:
- One room, one router, under 60 square metres
- No need to run cable to another floor
- Fewer than fifteen simultaneous visitors
- No cameras or devices needing remote monitoring
In that situation, adding one access point yourself is enough, the steps are in the guide to setting up two routers on one network.
Frequently asked questions
What's the first question to ask a prospective installer?
Whether they carry out a site survey before quoting a figure. Quotes based only on floor area over the phone almost always miss, because wall materials and cable routes matter far more than square metres.
Who should hold the admin password once it's done?
You, or at least you as well. An installer who withholds management panel access leaves you dependent on them for the smallest change, including changing the Wi-Fi password.
What's reasonable to ask for at handover?
Configuration documentation, a layout plan of access points, a device list with their fixed IP addresses, and all passwords. Without those, another technician has to reverse-engineer everything if a problem arises later.
What warranty period is reasonable for installation?
For configuration, three to six months is commonly offered. Hardware follows the manufacturer's warranty. What matters is clarifying what's included, re-adjustment usually is, lightning damage usually isn't.
