Guest WiFi for Coaching Centres and Tuition Classes

A coaching centre’s WiFi has an unusual shape. The same hundred or thousand students come in every day, sit for two to six hours, and leave by a timetable. Faculty run video lectures and online tests on the same line that students use to look up a formula or, if nothing stops them, to stream cricket. The fee software and the CCTV recorder are usually on that network too.

That makes it a different problem from a cafe’s guest WiFi, and closer to setting up WiFi in a study library. This guide covers what to decide, in order, for a single-room tuition class up to a multi-branch institute.

Start with who is on the network

Write down every kind of user before you buy anything:

• Students, by batch, with the hours each batch is in the building.
• Faculty and admin staff, with their laptops and the office desktop that runs fees and admissions.
• Devices that are not people: a projector or smart board, a biometric attendance unit, CCTV, a printer.
• Visitors: parents on counselling day, a guest lecturer, the ISP’s technician.

Students and visitors go on the guest network. Everything else goes on your own network, kept apart from them. That split is the one decision that protects the fee data, and guest network isolation explains how to test that it really holds.

One login per student, not a password on the whiteboard

A shared password spreads in a week. Last year’s batch still has it, the shop downstairs has it, and when you change it every student’s phone has to be reconnected. It also tells you nothing about who was online.

Two login methods suit a coaching centre:

• OTP to the student’s own phone. The student enters a number, gets a one-time password by SMS or WhatsApp, and is online. The number ties the session to a person, which is also what Indian rules on public WiFi expect. The OTP login page handles returning students without staff involvement.
• A voucher per batch. A batch of codes created for the duration of a course, 30 days for a monthly batch, 90 for a term, handed out at admission. Each code stops working on its own at the end. Vouchers as access control explains why the expiry is the point.

Many centres run both: OTP for students, vouchers for parents and visiting faculty. Because most students are under 18, read the section on minors below before you choose.

Limits that fit a class day

Per-student limits are what keep a 100 Mbps line usable with 80 phones on it. Three numbers, set once per branch:

• Speed per student. Enough for a lecture stream and a PDF, not enough to make a 2 GB download worth starting. Time and speed limits covers how to pick a number.
• Devices per student. One or two. A student with a phone and a tablet is normal; a student sharing a login with four friends is a shared password again.
• Session length. Match it to a batch. A session that ends after the batch’s hours keeps the network for students who are actually in class.

If online tests run on the same line, size the line for the test, not for an ordinary day. Bandwidth planning walks through the arithmetic.

Block what you don’t want in a classroom

Coaching centres ask for blocking more than any other kind of venue, and the honest answer is a DNS-based block. The network’s DNS server answers lookups for a blocked domain, or a whole category, with a dead end, so the site never loads on a phone that is using the network’s DNS. No traffic is read or decrypted.

What that gives you: streaming, social media, gaming and adult sites off the default student setup, plus a security threats category that stops known malware and phishing domains. What it does not give you: a guarantee. A student who turns on a VPN or sets a private DNS on their phone goes around it. Blocking websites on guest WiFi says exactly where the line is. Treat the block as a rule with a tool behind it, and keep the rule in the student handbook too.

Blocking is also not monitoring. Guest WiFi software can show you who is online and when. It does not show what a student is reading, and it should not be sold to parents as if it did.

WiFi that follows the timetable

A centre that teaches from 7am to 9pm has no reason for a live student network at midnight. A weekly open hours schedule switches the guest network off outside class hours and on again before the first batch. A student who connects during the gap sees a closed message you wrote, not a broken network, and the staff network is not affected.

Set a different schedule per branch if branches keep different hours, and a shorter one on Sundays if only a doubt session runs. Open hours for guest WiFi explains how the schedule behaves.

Students under 18

Most coaching students are minors, and India’s Digital Personal Data Protection Act, 2023 requires verifiable consent from a parent or guardian before a business processes a child’s personal data. It also bans tracking, behavioural monitoring and targeted advertising directed at children.

For WiFi that means three things. Take the consent at admission, where you already meet the parent, and ask your legal adviser what form it should take. Never use student numbers for marketing. And keep contact details hidden from staff who do not need them: a dashboard that masks numbers by default, and asks for an OTP before revealing them, is the right default for a building full of teenagers’ phone numbers. What a venue may collect at login covers the Act in more detail.

Several branches, one dashboard

Institutes grow by opening branches, and each branch brings a router, an ISP and a local manager. Guest WiFi software puts them on one screen: which branches are online, which router has gone down, and the settings for each. Limits, the timetable, blocked sites and login methods are set per branch, so a 7am centre and a 2pm centre do not have to share one schedule. Multi-location guest WiFi covers what to centralise and what to leave local.

What this will not do

Guest WiFi software is not a classroom tool. It will not push a test to tablets, record attendance, lock a phone during an exam or show you what a student watched. It puts students online under rules you set, keeps them off your office network, and tells you who was connected when. If you need proctoring or device management, that is separate software, and it will run on the same network.

Where Wyfy Guest fits

Wyfy Guest is guest WiFi software for venues in India, and coaching centres use the same features a library or a co-working space does: OTP login by SMS, WhatsApp or email, voucher batches with an expiry, per-student speed, device and time limits, DNS-based website and category blocking, a weekly open hours schedule with your own closed message, and one dashboard for every branch. Student numbers are masked from staff by default. Our team sets it up with you on your existing router and line where the router is supported, and the demo is free. If the centre has no one to look after the network, managed guest WiFi has our team do that part too.
