Motorcycle workshops, car garages, and car washes share one thing with salons: customers arrive and then wait. The difference is that the wait is often longer, an oil change takes 30 minutes, a major service can take half a day, and the environment is far harsher on electronics. This guide covers both: customer comfort and network durability.

Who uses the network

  • Waiting customers: video, social media, working from a laptop. The largest and least predictable share of use.
  • Till and admin: point-of-sale app, QRIS, card terminal, service records. Must always work.
  • Work tools: diagnostic scanners, mechanics' tablets, receipt printers, sometimes app-connected automatic wash machines.
  • Security: CCTV in the work area and car park.

Separate guests from the till and tools

This rule can't be skipped. Customers' phones must not share a network with the till, cameras, and scanners. Almost every router has a Guest Network feature; the steps are in the guide to separating a guest network, and the specific needs of tills and card terminals in the guide to networks for tills and card terminals.

Limit the guest network's speed, 3–5 Mbps per device is enough for smooth video, so a customer downloading a film doesn't make QRIS fail at the till. How to do it is in the guide to limiting Wi-Fi speed.

Protecting equipment from dust, heat, and vibration

Home routers are designed for living rooms, not areas full of brake dust, water vapour from wash machines, and heat from compressors. A few things make a big difference:

  • Put the router in a closed room: the office, an air-conditioned waiting room, or a ventilated panel box. Signal from there usually still reaches the waiting area next door.
  • For open work areas, use an outdoor access point (IP65 or better) mounted on a wall or pole 3–4 metres up, cabled back to the indoor router. See the PoE guide so you don't need a power socket up there.
  • Keep away from large machinery: compressors, welders, and electric motors emit interference that can degrade 2.4 GHz signal. Explained in the guide to Wi-Fi interference.
  • Clean the router's vents every few months. Accumulated dust makes routers overheat and restart, see the guide to overheating routers.
  • Add a small UPS for the router and till. Wash machines and compressors often cause brief voltage dips, and the router is the first thing to drop. See the guide to a UPS for your router.

Giving customers access

Workshop customers often have dirty hands and don't want to type a long password. Put a Wi-Fi QR code in the waiting room and at the till. Change the guest password monthly, or use a simple login page if the workshop is busy enough.

Using Wi-Fi for the business

  • Put the Google Maps review link next to the QR code. A customer who has just had a satisfying service is the best moment to ask for a review.
  • If you use a login page, offer an opt-in for next-service reminders via WhatsApp, with clear consent. It's the most sensible reason a workshop customer would give you their number.
  • Show the price list and promotions on the welcome page. More ideas in the guide to Wi-Fi marketing for small businesses.

What to do

For workshops and car washes: separate guests from the till and tools, limit per-guest speed, keep the router in a closed room or use an outdoor access point for the work area, add a UPS, and give access via QR code. The environment is harsh, but with the right placement the network can last for years.

Frequently asked questions

What router suits a dusty workshop?

An ordinary home router is fine as long as it sits in a closed waiting room or office, not in the work area. If it must be in the open, use an IP65-rated outdoor access point mounted high on a wall.

Do car diagnostic tools (OBD scanners) need internet?

Many modern scanners update their databases online and some use Wi-Fi to connect to a tablet. Put them on the staff network, not the guest network, and give them priority if the router supports QoS.

What internet speed does a small workshop need?

For 5–10 waiting customers, the till, and cameras, a 30–50 Mbps plan is usually enough. What matters more is limiting per-guest speed so one person can't use it all.
