Wi-Fi Dropping / Disconnecting
TP-Link Wi-Fi Router
Severity: ModerateWhat Does This Error Mean?
Frequent Wi-Fi drops from a TP-Link router are usually caused by channel congestion from neighbouring networks, a firmware bug, or the router overheating. Changing the Wi-Fi channel and updating firmware resolves most cases.
Affected Models
- TP-Link Archer AX series
- TP-Link Archer A series
- TP-Link Archer C series
- TP-Link Deco mesh system
Common Causes
- Wi-Fi channel congested — too many nearby networks on the same channel
- Router overheating — causing random resets
- Firmware bug causing stability issues
- 2.4 GHz band interference from microwaves, cordless phones, baby monitors
- DHCP lease time too short — devices losing IP address
- Router placed in an enclosed space with no ventilation
How to Fix It
-
Change the Wi-Fi channel.
Log into the router at 192.168.0.1. Go to Wireless → Advanced → Channel. For 2.4 GHz, try channels 1, 6, or 11 (these are the only non-overlapping channels). For 5 GHz, try a less crowded channel. Use a Wi-Fi analyser app (e.g. Wi-Fi Analyser on Android) to see which channels are least congested in your area.
-
Update the router firmware.
Log into the router at 192.168.0.1. Go to Advanced → System Tools → Firmware Upgrade → Check for Updates. Alternatively, download the latest firmware from tp-link.com/en/support/ for your model. Firmware updates frequently address Wi-Fi stability bugs.
-
Ensure the router has adequate ventilation.
TP-Link routers should be placed in open air with nothing on top of them. Do not put them in a drawer, cabinet, or enclosed shelf. If the router is hot to the touch, it is overheating — this causes random drops and reboots.
-
Increase the DHCP lease time.
Log into the router at 192.168.0.1. Go to Advanced → Network → DHCP Server. Increase the Address Lease Time from the default (often 120 minutes) to 1440 minutes (24 hours). Short lease times cause devices to re-negotiate their IP address, causing brief disconnections.
-
Enable band steering or separate the bands.
If your devices are jumping between 2.4 GHz and 5 GHz unexpectedly, try giving each band a different SSID name. Connect devices that need range to 2.4 GHz and devices that need speed to 5 GHz manually. This prevents the router from switching devices between bands, which can cause apparent drops.
Frequently Asked Questions
Why does my TP-Link keep disconnecting every few hours?
Disconnections every few hours on a TP-Link router often indicate the router is rebooting — either from overheating, a firmware crash, or a scheduled restart. Check whether the ISP connection light also drops when the Wi-Fi drops (full reboot) or only the Wi-Fi LED (Wi-Fi module crash). Updating firmware and improving ventilation resolve the majority of scheduled or thermal reboot issues.
