Network problems can bring your entire business to a halt. Before calling IT support, there are several troubleshooting steps you can take that may resolve the issue or at least help your IT provider diagnose it faster.
Step 1: Identify the Scope
Is the problem affecting one device, multiple devices, or everyone? If it's one device, the issue is likely with that device. If it's everyone, the problem is probably with the router, switch, or internet connection itself.
Check if the issue affects wired and wireless connections equally. If wireless is down but wired works, the problem is with your Wi-Fi. If both are down, it's likely the router or ISP.
Step 2: Power Cycle Your Equipment
It's a cliché because it works. Unplug your modem and router (in that order), wait 30 seconds, then plug the modem back in first. Wait for it to fully connect (all lights stable), then plug in the router. Wait another 2 minutes for everything to stabilize.
If you have a separate network switch, power cycle that too. Many network issues are caused by memory leaks or stuck processes in networking equipment that a restart clears.
Step 3: Check Physical Connections
Loose or damaged cables are more common than you'd think. Check that all ethernet cables are firmly seated — you should hear a click when they're properly connected. Look for kinked, frayed, or chewed cables (pets are a frequent culprit).
If you're using a switch or patch panel, verify that the correct ports are connected and that link lights are active.
Step 4: Test Your Internet Speed
If you have a connection but it's slow, run a speed test from a wired device connected directly to the router. Compare the results to what your ISP plan promises. If speeds are significantly below what you're paying for, the issue may be with your ISP rather than your internal network.
Step 5: Check for IP Conflicts
IP address conflicts occur when two devices are assigned the same address, causing intermittent connectivity issues. If devices are randomly losing connection, open Command Prompt (Windows) or Terminal (Mac) and type 'ipconfig /release' then 'ipconfig /renew' (Windows) or restart the network interface.
