Connect a phone to your guest Wi-Fi and try to open a shared printer or the router settings. If either one responds, the guest network needs attention.
Guests need internet access, not a path to business computers, files or network equipment.
Keep guests away from business systems
Create a separate guest network rather than sharing the Wi-Fi used by staff. The router or firewall should enforce the separation. Giving the networks different names does not do that.
Guests should be able to reach the internet but not your business devices. Test that a connected guest cannot open shared folders, printers, router settings or other internal systems.
Some equipment calls this feature guest isolation. More advanced equipment may use a separate virtual network. You do not need to know the label, but the person configuring it should be able to show that the separation works.
Replace the old shared password
A password that has been on the wall for years is difficult to control. Former visitors can keep using it, and staff cannot tell who has shared it.
Use a guest portal or temporary access code if your equipment supports one. Codes can expire after a visit or at the end of the day. For a small office, changing the guest password regularly and keeping it separate from the staff password is still an improvement.
Avoid collecting personal information unless the business genuinely needs it and has a clear way to protect it.
Limit what guests can do
Guest access is for normal internet use. It does not need to support large downloads or constant connections.
Your router may let you set time limits or prevent one guest from using most of the internet connection. Choose limits that protect business work without making the service frustrating for ordinary visitors.
You can also block traffic between guest devices. This helps stop one visitor's device from connecting directly to another device on the same guest network.
Keep the equipment updated
Router and wireless access point updates fix security problems and reliability issues. Check that the equipment still receives updates from its manufacturer and replace it when support ends.
Change the administrator password from the factory default. Only authorised staff or your IT provider should be able to change the network settings. Protect the administrator account with multi-factor authentication if the system offers it.
Write down the setup
Record who manages the guest network, where its settings are stored and how access is changed. Include the equipment model, support contact and update process.
Review the setup when you replace network equipment, move offices or change IT providers. A guest network can lose its separation after a rushed reset or incorrect configuration.
Test rather than assume
Connect a test device as a guest and confirm that it can browse the internet but cannot reach business systems. Check this again after major network changes.
If nobody can show that guest access is separated, book a guest Wi-Fi security consultation with JCPIT Support. We will review the network settings and the evidence that visitor devices cannot reach business systems.
