Business Internet Down? What to Check Before Calling Your ISP
Is the whole business offline, or only one device?
Start by checking the scope. If several devices cannot reach different websites, investigate the shared connection. If one laptop fails while another works on the same network, start with that device. A Wi-Fi connection alone does not prove the office has internet access.
For a Maryland shop, practice, or small office, the immediate goal is to keep essential work moving and give the right support team useful evidence. Do not factory-reset a business router or change firewall, VPN, DNS, or static-IP settings just to see what happens.
1. Identify what stopped working
Write down the start time and whether the problem affects the entire site, one room, a few devices, or one application. Test two unrelated websites. Ask whether phones, payment terminals, and cloud applications are affected too. Use a separate mobile connection to check an application or provider status page when the office connection is unavailable.
If websites work but one business application does not, check that application's service status and your account access before treating the incident as a complete internet outage.
2. Compare a wired device with Wi-Fi
If you have an approved Ethernet connection, compare a wired computer with a wireless computer. Keep the test simple and record what works. If wired access works while Wi-Fi fails, focus on the wireless path. If both fail, collect evidence about their shared connection. Microsoft's Ethernet troubleshooting guide and Wi-Fi troubleshooting guide provide device-specific checks.
For a device that joins Wi-Fi but cannot browse, use our Wi-Fi connected but no internet guide.
3. Check power, cables, and the provider's status
Look for an unplugged power supply, loose Ethernet cable, or changed indicator light. Record the device model and light pattern so you can compare it with the correct manual. Do not unplug equipment that supports other people without agreeing on a maintenance window.
Use the provider's official account or support channel to check the service tied to your business location. Comcast Business describes its account-based support options in its service interruption guidance. A nearby outage report is a clue; it does not confirm the condition of your own circuit. FMA Connect does not perform a live outage lookup.
4. Check the router's connection state
An authorized administrator can compare the router's local internet status with what users observe. With an Ericsson Cradlepoint device, follow the vendor's no internet or connection troubleshooting guidance. Record whether local traffic works, the modem connects, and cloud management is reachable. Those are different observations.
If the device is offline remotely, someone may need approved local access to continue. Share logs only through an appropriate support channel and remove credentials and private device identifiers from public messages.
5. Use an existing backup plan, then document the result
If your business already has an approved backup connection, follow its documented procedure. Confirm essential applications actually work after the change. Switching connections can interrupt active sessions. Avoid improvising changes during a busy period.
When service is stable, use our backup internet test checklist to plan a controlled test. A backup that has never been tested is an unresolved dependency.
What should you send to support?
Provide the start time, affected users and services, wired-versus-wireless comparison, indicator changes, provider status, and steps already tried. Keep passwords, MFA codes, account numbers, and customer records out of the summary. The provider should handle a confirmed service outage; local network or device problems may need separate assistance.
Still having trouble? Run FMA Connect✓.
Run FMA Connect✓ to organize observations using FMA SHERPA: Service, Hardware, Environment, Reachability, Provisioning, and Assessment. Create a Connect Report, review it, and choose what to share. It is guided troubleshooting, not an automated diagnosis.
For hands-on assistance, review Remote Help. For a network upgrade or backup connection project, request a scoped project. Learn more about FMA's internet and networking support. Provider restoration, equipment, and larger implementation work are separate from troubleshooting.
