How to Fix TP-Link Router Keeps Rebooting on Its Own?

Summary: A TP-Link router that keeps rebooting on its own is usually caused by overheating, a faulty power adapter, outdated firmware, or a hardware defect. Start by checking the power supply and ensuring proper ventilation, then update the firmware and check for electrical issues.

Your TP-Link router restarts itself every few minutes without warning. The lights go off, come back on, and the boot cycle repeats over and over. Every device in the house loses internet during each reboot, and by the time the router comes back online, it drops again a few minutes later.

This is a common problem with TP-Link routers and it almost always has a fixable cause. Here are the most effective solutions, starting with the ones that work most often.

Check the Power Adapter

A faulty or underpowered power adapter is the number one cause of random router reboots. The adapter might look fine on the outside but could be failing internally, delivering inconsistent voltage that causes the router to lose power momentarily and restart.

Feel the power adapter brick while the router is running. If it is extremely hot, it is likely failing and needs replacement
Check that the adapter specs match what your TP-Link router requires — the voltage (V) and amperage (A) must be the same as what is printed on the label on the bottom of the router
Try plugging the adapter into a different wall outlet — a loose or faulty outlet can cause intermittent power loss
If you have access to another TP-Link power adapter with the same specs, swap it in and see if the rebooting stops

Prevent Router Overheating

TP-Link routers, especially the Archer series, generate significant heat during operation. When the internal temperature exceeds safe limits, the router reboots itself as a thermal protection measure.

Move the router to an open, well-ventilated area — not inside a cabinet, on a carpet, or stacked on top of other electronics
Make sure the ventilation holes on the sides and bottom of the router are not blocked by dust or objects
If the room temperature is high, point a small fan toward the router or place it near an air conditioning vent
Clean the vents with compressed air every few months to remove dust buildup

Update the Router Firmware

Buggy firmware is a well-known cause of reboot loops on TP-Link routers. TP-Link releases firmware updates that fix stability issues, memory leaks, and other bugs that can trigger random restarts.

Open a browser and go to 192.168.0.1 or tplinkwifi.net
Log in with your admin credentials
Go to System Tools > Firmware Upgrade (or Advanced > System > Firmware Upgrade on newer models)
Click Check for Updates — if an update is available, download and install it
If auto-update does not work, go to the TP-Link support website, search for your exact model and hardware version, and download the latest firmware manually
Upload the firmware file through the admin panel and let the router install it

Important: Do not turn off the router during a firmware update. A failed update can brick the device.

Check for IP Address Conflicts

If two devices on your network are assigned the same IP address, it can cause the router to crash and reboot. This happens more often when you have manually assigned static IP addresses to devices that conflict with the DHCP range.

Log into the router admin panel at 192.168.0.1
Go to DHCP > DHCP Client List
Check if any two devices share the same IP address
If you find duplicates, go to DHCP Settings and adjust the IP pool range to avoid conflicts with any static IPs you have assigned

Disable Auto Reboot Schedule

Some TP-Link routers have a scheduled reboot feature that is enabled by default. If your router reboots at the same time every day, this is likely the cause:

Log into the admin panel
Go to System Tools > Reboot Schedule (or Advanced > System > Reboot Schedule)
If the schedule is enabled, either disable it or adjust the time to a period when you are not using the internet like 3 AM

Check for Electrical Interference

Routers are sensitive to electrical interference from other devices. If your TP-Link router is placed near a microwave, cordless phone base station, baby monitor, or large speaker, the electromagnetic interference can disrupt the router circuitry and trigger reboots. Move the router at least 3 feet away from any such devices and see if the problem stops.

Factory Reset as a Last Resort

If nothing else works, corrupted internal settings might be causing the reboot loop. A factory reset wipes everything clean:

Press and hold the Reset button on the back of the router with a pin or paperclip for 10 seconds
Release the button and wait for the router to restart completely
Set up the router from scratch — configure your WiFi name, password, and internet connection type

If the router continues to reboot even after a factory reset with a verified good power adapter, the hardware itself is likely failing and needs to be replaced. Contact TP-Link support for warranty options if the router is still within the warranty period.

Q.1 Can a too many connected devices cause my TP-Link router to keep rebooting?

Ans. Yes, if the number of connected devices exceeds your TP-Link router capacity, the processor and memory can become overwhelmed which causes the router to crash and restart. Budget TP-Link models are designed to handle 15 to 20 simultaneous connections while higher-end models like the Archer AX series can manage 40 or more. Check how many devices are connected in the DHCP Client List on your router admin page. If the number is close to or exceeds the recommended limit for your model, disconnect devices you are not actively using or upgrade to a router with higher capacity.

Q.2 How do I know if my TP-Link router rebooting is a hardware problem or a software problem?

Ans. Try a factory reset and set up the router with default settings without restoring a backup configuration. If the router runs stable after the reset but starts rebooting again after you restore your old settings, it is a software or configuration problem. If the router keeps rebooting even with factory default settings and a known good power adapter, it is a hardware problem. Also try running the router with no devices connected — if it still reboots on its own with nothing attached, that confirms a hardware fault or failing power adapter.

Q.3 Does TP-Link replace routers that keep rebooting under warranty?

Ans. TP-Link offers a standard warranty of 2 years on most router models though some regions may have different warranty periods. If your router is within the warranty period and keeps rebooting due to a manufacturing defect or hardware failure, TP-Link will repair or replace it free of charge. Contact TP-Link support through their website with your model number, serial number, and proof of purchase. They will guide you through basic troubleshooting first and if the issue is confirmed as a hardware defect they will process the warranty claim.
