Highly-rated TP-Link Wi-Fi extender discounted by CZK 535. Boasts a gigabit port and three antennas

Looking for a way to extend your Wi-Fi signal to the furthest corner of your house or apartment? On Alza, you can currently get the highly-rated TP-Link RE450 AC1750 extender for over five hundred crowns less, costing only CZK 994. It is equipped with a gigabit port and three antennas, capable of utilizing both 2.4GHz and 5GHz bands.

Quick summary:
✅ Makes sense if you have dead zones at home and want a proven extender with a gigabit port and 5 GHz band.
⚠️ Consider that it’s an older Wi-Fi 5 standard (not Wi-Fi 6) and that the extender will occupy an entire double socket.
💡 At CZK 994, it’s one of the lowest prices you’ll find for this proven model.

Why this extender is interesting

This TP-Link RE450 extender is aimed at people who have areas with weak or no Wi-Fi signal at home and don’t want to run cables. It extends the router’s range to distant rooms or floors, and thanks to its three antennas and dual-band operation, it can handle multiple devices connected simultaneously. But the main selling point isn’t just the features: it’s one of the best-selling extenders on Alza with thousands of units sold and a rating of 4.6 out of 5, so you know the product has been proven for years.

Key parameters in plain language

The AC1750 designation means dual-band operation: up to 450 Mbps on the 2.4 GHz band and 1300 Mbps on the 5 GHz band. In practice, this means you’ll use the more stable 2.4 GHz with greater range for general browsing and emails, while the faster 5 GHz is for streaming or gaming. A big plus compared to cheap repeaters is the gigabit Ethernet port, through which you can connect a TV, console, or player directly, turning the extender into a wireless bridge. It also supports EasyMesh, so it can be integrated into a compatible mesh network.

However, it’s fair to say that this is an older Wi-Fi 5 standard (802.11ac), not the newer Wi-Fi 6, or even Wi-Fi 7. If you have a modern Wi-Fi 6 router and want to get the most out of it, this extender will limit you. But for extending a typical home network, Wi-Fi 5 is still more than sufficient in the vast majority of households, and at this price, it’s a reasonable compromise.

Practical aspects: installation, placement, size

According to most users, setup is a matter of a few minutes via the WPS button or the Tapo app in Czech – just pair the extender with the router and move it to the target location. The signal strength indicator is useful, helping to find the ideal socket: too far from the router and the extender has nothing to amplify, too close and it won’t cover the necessary area. The option to turn off LED lights at night is also appreciated, as mentioned in many reviews.

However, expect two things. Firstly, the body is quite large and will occupy an entire double socket – a repeated criticism across reviews. Secondly, like any extender, it operates on the principle of a repeater, so the resulting speed in the extended network is usually lower than directly at the router, and the signal may not pass through strong obstacles (concrete floor) as desired. Placement here determines the outcome more than anything else.

What users say

The rating is solid: 4.6 out of 5 from 138 customers, 91% of buyers recommend the extender, and the return rate is low at 0.54%. Most often, people praise easy installation, significant improvement in range, and signal stability in multi-story houses and apartments. One user has been operating two units for years without issues, others appreciate the gigabit port and a good app compared to competitors.

However, there are also criticisms. Several users describe that the extender started disconnecting spontaneously after one to two years or stopped working reliably – given the low return rate, this is a minority, but it deserves mention. Some people find the setup unnecessarily complicated for an amplifier they expect to “plug and play,” and a few users state that the amplification was not as strong as they hoped. Here, a lot depends on the specific layout of the apartment and the distance from the router.

When it doesn’t make sense

If you have a modern Wi-Fi 6 router and want full speed, this extender will hold you back with its older standard – opt for a Wi-Fi 6 model. Those dealing with a large house with thick walls and wanting seamless coverage will be happier with a full-fledged mesh system rather than a single extender. And if you’re looking for a small, inconspicuous device, be aware that the RE450 will occupy an entire double socket.

Verdict: who it’s worth it for

If you want a proven way to rid your apartment or house of dead zones, the TP-Link RE450 AC1750 for CZK 994 is a sensible purchase – especially considering its rating of 4.6 out of 5, over 2,000 units sold, and a three-year warranty. For a saving of CZK 535 compared to CZK 1,529, you get a dual-band extender with a gigabit port and EasyMesh that will do its job in a typical household. Just keep in mind that it’s an older Wi-Fi 5 and a classic extender, not a mesh system or the latest standard. However, for targeted coverage of specific areas at a reasonable price, it’s one of the most reliable choices.

Are you solving weak Wi-Fi with an extender, or would you rather switch directly to a mesh system?
