The IT checklist for reliably working from home

Reliable work-from-home setups come down to four checks: strong, stable signal at your actual desk, a tested backup connection, a small UPS to survive brief power outages, and secured, updated work devices. Working from home reliably depends on more than just having WiFi, and this handful of specific checks catches most of the issues that turn into a missed call or a lost afternoon.
Connection reliability, not just speed
Confirm your work desk actually gets strong, stable signal, not just "connected." If your router is far from where you work, that's the single most common cause of dropped calls during work hours, and usually the easiest to fix with better placement or an added access point, a fix that's often cheaper and more effective than an internet plan upgrade.
A genuine backup connection
For anyone whose work depends on being reachable, a mobile hotspot or secondary connection as backup is worth having configured and tested before you need it, not discovered mid-outage during an important call, when there's no time left to troubleshoot it properly.
Power backup deserves consideration too
A router and modem losing power during a brief outage means losing internet entirely, regardless of your ISP or plan. A small UPS (uninterruptible power supply) keeping just the router and modem running for a short outage window is a genuinely underused, inexpensive safeguard for anyone whose work reliability really matters.
Basic security hygiene for work devices
Work devices should be on a secured, ideally separate, network from smart home devices, kept updated, and backed up. If your employer requires a VPN for work systems, make sure it's tested and working from home before you need it urgently, not discovered as broken during an actual deadline.
What we check on a home office visit
We test signal strength at your actual desk, confirm backup connectivity options, and check that your setup would survive a router restart or a brief outage without derailing your workday.
Key terms
- UPS (uninterruptible power supply)
- A small backup battery unit that keeps devices like a router and modem running for a short window during a power outage, preventing an immediate internet loss.
Frequently asked questions
What should I check to make sure my home office setup is reliable?
Four things: confirm strong, stable signal at your actual desk (not just 'connected'), have a genuine backup connection tested before you need it, add a small UPS to keep your router and modem running through brief power outages, and keep work devices secured, updated, and backed up on a separate network from smart home devices.
What's the most common cause of dropped calls while working from home?
A router that's too far from where you actually work. This is the single most common cause of dropped calls during work hours, and usually the easiest to fix with better router placement or an added access point, often cheaper and more effective than upgrading your internet plan.
Why would I need a UPS for my home office if my internet plan is fine?
Because a router and modem losing power during a brief outage means losing internet entirely, regardless of your ISP or plan. A small UPS keeping just the router and modem running for a short outage window is a genuinely underused, inexpensive safeguard for anyone whose work reliability really matters.
