To a lot of people, "setting up Wi-Fi" for a cafe or hotel sounds simple: buy a router, plug it in, set a password. Then, a few weeks later, the familiar problems start. One table eats all the bandwidth, the network crawls during the evening rush, someone shares the password with a neighbor, and the front desk repeats the same password to guests all day long. Before you know it, the thing that was meant to improve the customer experience has turned into a headache.
A properly built guest Wi-Fi setup heads all of this off in advance. Below, we've laid out what to pay attention to, in a practical order.
Step by step: where to start
- Separate the guest network from the business network. This comes first, and it's non-negotiable. A customer's phone shouldn't sit on the same network as your POS, your accounting, or your cameras. Separation means both security and stability.
- Put a captive portal on the entry point. A branded sign-in page instead of a password on the wall. The customer connects with one tap, or by SMS. It looks professional, and it meets the user-identification expectation.
- Set speed limits. Allocate each guest a certain speed so one person downloading a big file can't grind everyone else to a halt. "Per room" works for a hotel; "per device" works for a cafe.
- Set up content filtering. Block inappropriate or risky sites at the network level in a public space. It protects both your image and your network.
- Keep access logs. Who connected, and when having these logged automatically protects you from future headaches.
- Hand off the management. You're not going to babysit all of this every day. A good solution is managed remotely so when a change is needed, someone makes it without coming on site.
What changes by venue type?
Cafe and restaurant
Here the main goal is a friction-free experience. The customer sits down, connects with one tap, and drinks their coffee. Long registration forms don't work here people will just leave. "One-tap" or a quick SMS is the ideal choice.
Hotel and guesthouse
A hotel is a little different. A voucher (code) system works well here the front desk gives the guest an access code, tied to the room or the length of stay. For VIP guests, you can set up a separate, faster profile.
Co-working and business center
Since the users here are permanent, named accounts make sense. Each member has their own login and their own limit. When a visitor drops by, they get a temporary code.
The most common mistake: Buying a cheap home router and dropping it into a venue that serves 50 people. Home equipment isn't built for that load you'll be suffering during the evening rush. This is exactly where a business-grade solution shows its worth.
Can you do all of this on one device?
Yes and that's where the real convenience is. Instead of building out each of the steps above with separate pieces of equipment, you can bring them all together on one managed device: firewall, branded guest portal, speed limits, content filtering, access logs, and remote management all in one place.
Onyx Firewall is built around exactly this approach. You keep your existing routers and access points, we add the device, it's up and running in roughly ten minutes and we manage it remotely. Even if the internet or the cloud drops, the device keeps working on its last settings which means your guest Wi-Fi doesn't go down just because "the cloud" had a bad day.

Frequently asked questions
Do I have to throw out my existing routers?
No. The solution works with your existing equipment a device is added at the network entry point, and your Wi-Fi access points stay in place.
How many guests can it handle?
That depends on the size of the venue and the device you choose. When you send a request, we recommend a configuration based on your daily guest count.
Does the Wi-Fi stop completely when the internet goes down?
If the internet is down, there's naturally no external access but if the cloud management drops, the device keeps working on its own, guest login included.
Does each branch need separate management?
No. All branches are managed from a single panel, with changes applied remotely.
