Weak Wi-Fi signal in distant rooms, constant connection drops when watching videos, or slow file downloads—do you feel familiar? Repeater TP-Link TL-WA855RE solves these problems by boosting the existing network without installing cables. But how do you connect it correctly so it works effectively and doesn't create additional interference?

Many users mistakenly believe that simply plugging an amplifier into a power outlet will get it working. In practice, however, proper positioning, network settings, and sometimes even a firmware update are required. This article will discuss these issues. all stages: from choosing the optimal installation location to fine-tuning for maximum speed.

We won't limit ourselves to the basic instructions provided in the box—we'll explore nuances that manufacturers often gloss over. For example, we'll explain why a repeater might slow down your internet connection, how to avoid IP address conflicts, and what to do if the indicators aren't working properly. We'll also pay special attention to troubleshooting and alternative connection schemes for unusual situations.

If you have already tried to set up TL-WA855RE If you encountered any errors, there's a section at the end of the article with solutions to common problems. And for those just planning a purchase, we'll compare this repeater with other TP-Link models based on key parameters.

1. Preparing for connection: what you need to check before installation

Before unpacking the amplifier, make sure your network is ready to connect it. The main requirement - the presence of a working Wi-Fi router that supports standards 802.11n/g/b (For TL-WA855RE the old standard is enough 802.11n, but the speed will be limited to 300 Mbps). If your router only works in the range 5 GHz, this repeater won't work - it only supports 2.4 GHz.

The second important point is optimal distance between router and repeaterIf the booster is installed too close to the signal source, it won't be able to effectively extend the network. If it's installed too far away, the signal will be weak, and the booster itself will slow down the network. Ideal position:

• 📶 Medium signal strength zone: the Wi-Fi indicator on the smartphone shows 2-3 divisions out of 4.
• 🚪 Obstacles: there should be no more than 1-2 walls between the router and the repeater (concrete walls weaken the signal more than plasterboard walls).
• ⚡ Socket: The amplifier must be connected directly, without extension cords or power strips.

Also check:

• 🔧 Availability of a free electrical outlet 220V near the planned installation site.
• 📱 You must have a smartphone, tablet, or laptop on hand for setup (cable connection is not supported).
• 🔄 The router is in disabled mode WPS (if you don't plan to use it for connection).

⚠️ Attention: If your router uses non-standard security settings (for example, WPA3-Enterprise or 802.1X), TL-WA855RE will not be able to connect. In this case, you will need to create a separate network with support WPA2-PSK.

2. Unpacking and external inspection of the device

In a box with TP-Link TL-WA855RE you will find:

• 📦 The repeater itself (white case with two antennas).
• 📄 Quick start guide in several languages ​​(including Russian).

7. Common mistakes and their solutions

Even with proper setup, problems can arise. Let's look at the most common ones:

1. The repeater does not connect to the router

Possible causes and solutions:

• 🔍 Incorrect password: Make sure you're entering the password for your main network, not the repeater's. Characters are case-sensitive!
• 📡 Weak signal: Move the repeater closer to the router (indicator Signal should show at least 2 divisions).
• ⚙️ Incompatible security settings: Manually install on the router and repeater WPA2-PSK (Not WPA3 or mixed mode).

2. The Internet is slow through the repeater.

What to check:

• 📶 Channel congestion: Change the Wi-Fi channel in the repeater settings (see the optimization section).
• 🔄 Double NAT: If the repeater is distributing IP addresses from a different subnet, it may cause problems with some applications. Disable DHCP on the repeater (DHCP → DHCP Settings → Disable).
• 📡 Long distance: Reduce the distance between the router and the repeater or use the second repeater as a "bridge".

3. The repeater constantly reboots

Possible reasons:

• ⚡ Unstable power supply: Plug the repeater directly into a power outlet, without extension cords.
• 🔥 Overheat: Make sure the ventilation holes are not blocked and the repeater is not placed in direct sunlight.

2. Please connect to this network and set up again via http://tplinkrepeater.net.

Login and password to access the control panel after the reset: admin/admin.

Why did my internet speed drop by half after connecting the repeater?

This is a normal phenomenon for repeaters with a single radio frequency (like TL-WA855RE). The problem is that the device simultaneously receives and transmits data over the same channel, which reduces throughput by approximately 50%. To reduce losses:

• 📶 Connect the repeater to the router via an Ethernet cable (if the model supports this mode).
• 🔄 Use the repeater only for devices that don't require high speed (such as smart bulbs or printers).
• 🛒 Consider purchasing a dual-band repeater (e.g. TP-Link RE450), which works on 2.4 GHz And 5 GHz simultaneously.

Is it possible to connect a printer or IP camera to the repeater?

Yes, but with some reservations:

• 🖨️ PrinterIf your printer has an Ethernet port, connect it to the extender with a cable. For Wi-Fi printers, connect to the extender's extended network and add the printer as usual.
• 📹 IP camera: Similarly, connect via cable or Wi-Fi. Make sure the camera and repeater are on the same subnet (disable DHCP on the repeater if there are IP conflicts).

For stable operation of wired devices, it is better to use the repeater in the mode Access Point (access point), connecting it with a cable to the router.

How can I check that the repeater is actually boosting the signal and not interfering?

Follow these steps:

1. 📱 Connect to the main Wi-Fi network and measure the speed on the website speedtest.net in a place where the signal is weak.
2. 🔄 Connect to the extended repeater network and repeat the test in the same location.
3. 📊 Compare the results: if the speed has increased or become more stable, the repeater is working correctly.

Also note:

• 📶 Signal level: On your smartphone, check how many bars the Wi-Fi indicator shows when connected to the repeater.
• 🔄 Ping: In the command line, run ping 8.8.8.8 -t and see if there is any packet loss.
