Experiencing unreliable internet like a flickering lightbulb? Your connection might be disrupted and your internet keeps disconnecting due to various factors, such as router glitches, faulty cables, or network congestion at home.
Fortunately, these issues can often be resolved with straightforward troubleshooting steps. Drawing from my experience as a former broadband technician, we've encountered and solved this problem numerous times.
In this guide, we'll outline the top 5 most common solutions for improving a weak internet signal. Additionally, we'll provide extra tips and resources for more advanced troubleshooting.
Top 5 Causes of Internet Disconnection
For more detailed solutions to each of these common internet issues, scroll down the page on the specific problem for an instant solution.
Here are the primary reasons for internet disconnections:
Restarting your modem and router:
If your internet disconnects, always the first step in troubleshooting internet problems, restarting your equipment can often resolve glitches and restore smooth operation.
Weak or unstable Wi-Fi signal:
This can be caused by obstructions, limited range, or interference from other devices and networks.
Network congestion in your home:
Trying to do too much with limited bandwidth can lead to network congestion. Consider reducing usage or upgrading your internet plan.
ISP outages and slowdowns
These are typically caused by infrastructure issues that your ISP needs to address. If outages are frequent and unresolved, switching ISPs may be necessary.
Damaged network cables
Often requiring a technician to diagnose and repair, damaged cables can be a hidden cause of connectivity problems.
Internet Disconnected? Follow These Troubleshooting Steps for Fixing
Restart Your Modem and Router
If you're experiencing a weak internet signal, the first step is to restart your modem and router. It's a quick, simple, and often effective solution.
To restart your modem, router, or gateway (modem/router combo unit), follow these steps:
- Step 01: Unplug the power cable from the back of the equipment.
- Step 02: Wait for 60 seconds.
- Step 03: Reconnect the power cable.
- Step 04: Allow the equipment to reboot.
Weak Internet Signal
Distance from your router or obstacles like walls can cause intermittent internet disruptions. Check your device’s Wi-Fi signal strength and avoid placing your router near materials that block signals (like metal or water). Other electronic devices such as microwaves and baby monitors can also cause interference.
Slow Internet Plan
If you're trying to use more bandwidth than your internet plan allows, you may experience slowdowns that feel like your internet disconnects. This is especially common when multiple users are online simultaneously.
To determine if an upgrade is needed, check your internet plan's advertised speed by using our guide on speed tests. If your actual speed closely matches the advertised speed, consider upgrading.
You're Experiencing Internet Outages
Internet outages can vary widely, from brief disruptions to extended downtime. If your internet keeps disconnecting randomly, then this could be due to outages from your Internet Service Provider.
Check for outages using your ISP's app, or website, or by contacting them directly. Request information on past outages to confirm if they're causing your issues. ISPs usually keep detailed records of customer connections, allowing support to provide outage details and estimated restoration times.
If persistent disconnections frustrate you, consider switching ISPs to explore newer options like fiber and 5G home internet. Enter your zip code to discover available providers in your area.
Networking Cable Issues
Issues with your home's networking cables can cause “Internet Disconnected” issues if they're damaged, loose, or improperly configured.
Here’s what to check for:
- Damaged cables: Look for tears, chew marks, and kinks in all networking cables. Ensure coaxial cables are securely screwed into both the modem and wall outlet. Don't forget to inspect the Ethernet cable connecting your modem to the router or computer if your internet keeps disconnecting.
- Loose cables: Tighten coaxial cables securely and ensure Ethernet cables audibly click into place when inserted. Loose cables can intermittently disrupt internet connections, especially if they move.
- Unused active coaxial lines: Open coaxial lines not connected to any equipment can act as antennas, causing radio interference in your network. During professional installs, ask technicians to seal unused coaxial outlets.
Fixing cable issues if your internet disconnects often may require specialized tools and skills. Consider requesting a technician visit from your Internet Service Provider if you suspect cable problems.
Still No Luck. What's Next?
Contact your ISP. They have the tools and expertise to diagnose and resolve broadband issues, which may involve testing the utility pole tap, checking signal levels, conducting advanced connectivity tests, and other specialized procedures you can't perform independently.
While scheduling and waiting for an appointment can be inconvenient if the internet disconnected, it's often the most effective way to permanently resolve your issue.
