Access Rules

Understand what happens after the guest is approved.

Item Rule
Network name Guests connect to mflexvisitor.
Initial Wi-Fi password Use greeting to join the visitor network before the splash page approval process.
Maximum duration Guests can request a maximum of 5 days of access.
Reconnect behavior If the guest disconnects and reconnects within the approved time, the device should automatically regain internet access.
Expired approval If the approval period has expired, the guest must complete the request process again.
Multiple devices Authorization applies to the approved guest credentials. After approval, the guest can use the same name and email address on another device and connect without entering the sponsor email again during the approved period.

Troubleshooting

Use these checks if the guest cannot connect or approval is not working.

The splash page does not appear.

Disconnect and reconnect to mflexvisitor. If the page still does not appear, open a browser and try visiting a non-company website such as google.com to trigger the splash page.

The sponsor email returns an error.

Confirm the sponsor email address is typed correctly and uses one of the approved domains: mflex.com, multek.com, dsbj.com, us.dsbj.com, or sourcephotonics.com.

The request is still pending.

Ask the sponsor to check their inbox and junk email for the approval message. The guest will not receive internet access until the sponsor approves the request.

The guest was connected earlier but cannot connect now.

The approval period may have expired. Reconnect to the visitor network and complete the request process again.

The guest changed devices.

During the approved period, the guest can use the same name and email address on another device. If access is not granted automatically, repeat the request process.
