A backup is useful only if it survives the failure that takes down the primary connection. Start by defining how long you must remain online and what work must continue, then choose a genuinely separate route and test it.
1. Define the Minimum Working Day
List the tasks that cannot wait: one video call, VPN access, payment processing, cloud files or customer support. Ask the employer or client what security rules apply to mobile hotspots, public workspaces and personal devices. Estimate the devices and hours the backup must support.
2. Choose an Independent Connection
If the main service is fibre, a mobile SIM on a network tested at the premises can provide a different access method. If the primary connection is already mobile, a second SIM may still share local infrastructure or coverage weaknesses; test another network and understand that independence is not guaranteed. Satellite can offer a different path but has its own installation, power, plan and sky-view requirements.
Use the ComReg coverage map to shortlist mobile networks, then test at the property. For the primary service, follow our Eircode broadband check.
3. Include Power and Local Wi-Fi
A second internet service will not help if the router, network unit or laptop has no power. Identify every device needed for the connection and check its power requirements. Use manufacturer instructions and competent electrical advice for any backup-power equipment; do not improvise mains wiring.
Also separate an internet failure from a Wi-Fi failure. Keep an Ethernet cable available, know how to connect directly to the router and record the router’s restart procedure without exposing passwords.
4. Write a Failover Runbook
- Confirm whether the fault affects one device, Wi-Fi or the provider service.
- Connect the backup router or hotspot and verify internet access.
- Check the VPN, calling platform and critical cloud service.
- Reduce non-essential traffic and notify colleagues if capacity is limited.
- Open a fault with the primary provider and record the reference.
- Move to the alternative workspace if the backup cannot support the work.
5. Verify a Nearby Workspace
A directory listing is not enough for an emergency plan. Contact a nearby hub, library or workspace and confirm current opening hours, booking requirements, accessibility, call facilities, connection availability and what identification or payment is needed. The Government describes Broadband Connection Points as public-access locations created ahead of direct premises connections, while NBI says they support work, study and other community uses. Facilities and access vary by location.
What to Keep Offline
- Provider fault and support details.
- Backup activation steps and equipment location.
- Employer IT contact and approved connection rules.
- Alternative workspace contact, route and opening hours.
- A dated test log and replacement schedule for batteries or SIM credit.
