Extends Wi-Fi signal for a few hundred! TP-Link RE315 costs only 799 CZK

Do you have a spot at home where Wi-Fi doesn’t reach? TP-Link RE315 now costs 799 CZK with code ALZADNY20 instead of 999 CZK. It’s the cheapest way to cover a dead spot – but it’s fair to say what to expect from an extender and when it’s better to opt for a mesh system.

Quick summary:
✅ Makes sense if you need to cheaply and easily get a signal where the router doesn’t reach (back room, upstairs, outdoor camera).
⚠️ Consider that as an extender, it reduces speed (especially in multi-story homes) and only has a 100Mbit LAN port.
💡 For 799 CZK with code ALZADNY20, it’s a popular and proven choice (4.6/5 from 550 reviews, over 20,000 sold).

The simplest way to cover a dead spot

The biggest praise in reviews goes to the ease of installation – either via the Tether app in half a minute, or completely without the app, just using the WPS button. The extender reliably covers areas where Wi-Fi previously didn’t reach – a back room, upstairs, a hallway, or an outdoor camera. A big plus is the RJ-45 port, which you can use to connect devices like an IP phone, TV, or console via cable. And with TP-Link routers via OneMesh, it creates a single network with the same name and seamless switching.

Extender, not mesh – what to expect from it

This is crucial, and more experienced users aptly summarize it in reviews: an extender merely retransmits the received signal with the strength it has at its location. So, place it where the signal is still decent, not in the worst corner. In multi-story homes and when burdened with more devices, speed noticeably decreases. Second point: the device only has a 100Mbit LAN port, which throttles faster connections. If your main concern is range to a single spot, the RE315 is a cheap and functional fix. However, if you want a seamless fast network throughout the house for streaming, gaming, and multiple users, a now affordable mesh system is a better choice.

For a cheap and quick solution to a single weak spot, the RE315 is a bullseye – after all, that’s why over 20,000 units have been sold. Just don’t consider it a replacement for a full-fledged network and be aware that it is quite bulky, so it will cover the second socket in a double outlet.

Is a cheap extender for one spot enough for you, or are you aiming straight for a whole-home mesh system?
