FAQ: Frequently Asked Questions about Setting Up the TP-Link TL-WR841N

Can TL-WR841N be used as a repeater?

Yes, but with some caveats. Router TL-WR841N does not support repeater mode out of the box, but you can:

1. Update firmware to a version with support Universal Repeater (there are unofficial firmwares, for example, DD-WRT).
2. Use a cable connection (connect the router to the main router via a port LAN, turning off DHCP).
3. Buying a specialized repeater is more reliable and easier.

The official TP-Link firmware does not provide repeater function for this model.

How to limit internet speed for individual devices?

In the router TL-WR841N there is a function Bandwidth control (QoS), but it limits speed by traffic type, not by device. To limit a specific device:

1. Go to DHCP → DHCP Client List and find the MAC address of the target device.
2. Go to Bandwidth Control → Control Rules.
3. Add a rule by specifying the MAC address of the device and the speed limit (e.g. 5 Mbps).

For more flexible control, use firmware from third-party developers (DD-WRT, OpenWRT).

Why does the router get hot and turn off?

Overheating is a common problem TL-WR841N, especially with prolonged exertion. Causes and solutions:

• 🔥 Poor ventilationThe router is in a closed cabinet or near heat sources. Solution: Move it to a ventilated area.
• 🔌 Faulty power supply: If the router turns off under the slightest load, try another power supply with the same parameters (9V 0.6A).
• 🔄 High trafficIf you're simultaneously using torrents, online games, and streaming video, your router may not be able to handle it. Limit the number of connected devices or update your firmware.
• 🛠️ Wear of componentsIf your router is old (5+ years old), the thermal interface on the chip may have dried out. The solution is to disassemble it and replace the thermal paste (requires soldering skills).

Normal operating temperature for TL-WR841N — up to 60°C. If the case is hot (you can't hold it in your hand), this is a cause for concern.

How to connect IPTV to TP-Link TL-WR841N?
