Internet Drops Every Few Minutes? Here's How to Fix It
Key Takeaways
- The most common causes of internet that drops every few minutes are overheating equipment, loose coax or Ethernet connections, and outdated modem firmware.
- Start with a full power cycle of your modem and router, then check every cable connection by hand before moving to advanced fixes.
- If your equipment checks out and drops continue, the problem is likely signal noise on the line, and your internet provider needs to send a technician.
Few things are more frustrating than internet that works for a few minutes, cuts out, then comes back, over and over. The good news: this pattern almost always points to a short list of causes, and most of them are fixable at home in under 30 minutes. Work through the steps below in order. Each one takes just a few minutes.
Why Does My Internet Keep Dropping Every Few Minutes?
Internet that drops repeatedly is usually caused by one of these problems:
- An overheating modem or router
- Loose or damaged coax, Ethernet, or power cables
- Outdated firmware or a modem that needs a reboot
- Wi-Fi interference from neighbors or household electronics
- Signal noise or weak signal levels on your provider's line
- Aging equipment that can no longer hold a stable connection
The fixes below address each cause, starting with the easiest.
Step-by-Step Fixes for Internet That Keeps Dropping
1. Power Cycle Your Modem and Router the Right Way
A quick reboot fixes more connection problems than any other step, but it has to be done correctly.
- Unplug the power cord from your modem and your router.
- Wait a full 60 seconds. This clears the memory and forces the modem to request a fresh connection.
- Plug the modem back in first. Wait until its online light is solid.
- Plug the router back in and wait 2 minutes for Wi-Fi to come back.
If your connection is now stable, you're done. If it drops again within an hour, keep going.
2. Check Every Cable Connection by Hand
A coax cable that is even slightly loose can cause the exact on-again, off-again pattern you're seeing.
- Hand-tighten the coax cable on the back of the modem and at the wall outlet. It should be snug, not just resting in place.
- Check the Ethernet cable between your modem and router. Unplug it and plug it back in until it clicks.
- Look for kinks, chew marks from pets, or crushed sections along each cable. Replace any damaged cable.
- If your coax cable runs through a splitter, bypass the splitter temporarily and connect the modem directly to the wall. Old splitters are a very common cause of drops.
3. Check for Overheating
Touch the top of your modem and router. If either one feels hot rather than warm, heat is likely causing the resets.
- Move the device to an open area with airflow. Never keep it in a cabinet, closet, or stacked on other electronics.
- Stand it upright if it was designed to stand, and keep vents clear of dust.
- Keep it away from direct sunlight and heat sources like game consoles.
4. Rule Out Wi-Fi Interference
If your internet only drops on wireless devices, the problem may be Wi-Fi interference rather than your actual connection.
- Plug a laptop or desktop directly into the router with an Ethernet cable and watch it for 15 to 20 minutes.
- If the wired connection stays solid while Wi-Fi drops, the issue is wireless interference.
- Move your router away from microwaves, baby monitors, cordless phones, and Bluetooth speakers.
- Switch to the 5 GHz band in your router settings if your devices support it. The 2.4 GHz band is far more crowded, especially in apartments.
5. Check Your Modem's Event Log for Signal Problems
This sounds technical, but it takes two minutes and tells you a lot.
- Open a web browser and type 192.168.100.1 into the address bar (this works for most cable modems).
- Look for a page labeled Event Log or Status.
- If you see repeated entries like "T3 timeout," "T4 timeout," or "Lost MDD," your modem is losing contact with your provider. This is a signal problem on the line, not your equipment, and it means your ISP needs to investigate.
6. Update Your Router's Firmware
- Log in to your router's admin page. The address and password are usually printed on a sticker on the bottom of the router.
- Find the firmware or update section, often under Administration or Advanced settings.
- Install any available update, then let the router restart on its own.
Modem firmware is usually updated automatically by your provider, so focus on the router.
7. Test With One Device Removed at a Time
Occasionally a single faulty device floods the network and knocks everything offline. Smart home gadgets, old printers, and failing laptops are frequent offenders. Disconnect devices one at a time for 10 to 15 minutes each and watch whether the drops stop.
8. Factory Reset the Router
If nothing above has worked, reset the router to factory settings.
- Press and hold the recessed reset button on the back for 10 seconds using a paperclip.
- Wait for the router to fully restart, then set up your Wi-Fi name and password again.
Note: this erases your custom settings, so only do it after trying everything else.
9. Call Your Internet Provider
If drops continue after all of the above, the problem is almost certainly outside your home: a degraded line, a bad tap at the pole, water in an underground cable, or neighborhood congestion. When you call, tell them:
- The drops happen every few minutes, even on a wired connection.
- You have already rebooted, checked cables, and bypassed splitters.
- Your modem's event log shows timeout errors (if you found them in step 5).
Mentioning these details usually gets you past the basic script and straight to a technician appointment.
When to Replace Your Modem or Router
If your equipment is more than 5 years old, replacement is often the real fix. Older modems struggle with modern speed tiers, and aging capacitors cause exactly the kind of random dropouts described here. If you're renting equipment from your provider, buying your own modem and router typically pays for itself within a year and gives you newer, more reliable hardware.
Frequently Asked Questions
Why does my internet disconnect at the same time every day?
Drops that happen on a schedule usually point to neighborhood congestion during peak evening hours, a scheduled task on your network like a large backup, or interference from a device that runs at set times. If it happens between 7 and 11 p.m., congestion on your provider's network is the most likely cause.
Why does my Wi-Fi keep disconnecting but the internet is fine?
If wired devices stay online while Wi-Fi drops, the problem is your router or wireless interference, not your internet service. Try moving the router to a central location, switching to the 5 GHz band, and updating the router's firmware. If drops continue, the router itself may be failing.
Why does my internet drop only on one device?
A single device losing connection points to that device, not your network. Update its Wi-Fi drivers, forget and rejoin the network, and disable any power-saving setting that turns off the Wi-Fi adapter. On Windows, this setting is found in Device Manager under the adapter's Power Management tab.
Can too many devices cause internet to keep dropping?
Yes. Older routers can only handle a limited number of simultaneous connections. If your household has 20 or more connected devices on a router that is several years old, the router can become overwhelmed and drop connections. A modern Wi-Fi 6 or Wi-Fi 7 router handles dozens of devices without issue.
What do the T3 and T4 timeout errors in my modem log mean?
T3 and T4 timeouts mean your modem is losing communication with your provider's network, usually because of signal noise, a weak signal, or a line problem. These errors are almost never fixable at home. Report them to your provider and request a technician visit.
Does weather cause internet to drop repeatedly?
It can. Rain, wind, and temperature swings affect damaged outdoor lines, corroded connectors, and cracked coax fittings. If your drops get worse during storms or cold snaps, mention that pattern to your provider, since it strongly suggests a physical line problem outside your home.
Should I replace my modem or my router first?
Check the modem's event log first. If it shows timeout errors, the problem is the modem or the line. If the log is clean but Wi-Fi still drops, replace the router. When both are more than 5 years old, replacing both at once is usually the most cost-effective path to a stable connection.
