Yes

Both modes are possible. But the wired mode will be faster. The wireless mode requires the creation of a second Wi-Fi network. The configuration with the application is relatively simple.

An access point (AP) connected via network cable should always be placed before a repeater / range extender. And a repeater should not be placed where the reception of the existing Wifi is poor.

You can operate the Wi-Fi repeater on the campsite, but it will only work if you connect to the campsite's existing Wi-Fi. If you do not have the option of making settings on the campsite's main Wi-Fi network or logging in there, the repeater cannot amplify the signal on its own. It needs an existing connection to the main Wi-Fi network to extend the signal. Without such a connection or login to the campsite Wi-Fi, the repeater will not work automatically.

Yes, the TP-Link RE550 (300 Mbps on 2.4 GHz and 1300 Mbps on 5 GHz) can be useful to improve a poor Wi-Fi connection, but it depends on a few factors. When is it useful? If the Wi-Fi signal is weak in some areas - The RE550 is an extender (repeater) that amplifies the existing signal, so it can help to cover areas where Wi-Fi reaches poorly. If your main router supports 5 GHz - The 1300 Mbps band on 5 GHz is great for modern devices (smartphones, laptops, TVs) that support this frequency, offering faster and more stable performance. If you have problems with speed but not latency - An extender improves coverage, but can introduce a slight delay (latency), so it is not ideal for competitive gaming. When is it NOT the best solution? If the problem is slow ISP (e.g. slow fibre) - The extender does not increase the speed of your internet connection, only the Wi-Fi coverage. If your router is very old - If your original router does not support 5 GHz or has outdated Wi-Fi standards (e.g. Wi-Fi 4), the extender will not work wonders. If you have interference or too many connected devices - In these cases, a new router or a mesh system might be better. Alternatives to consider Powerline with Wi-Fi (e.g. TP-Link AV600 or AV1000) - Useful if Wi-Fi does not reach well and you want to use the mains to extend your connection. Mesh system (e.g. TP-Link Deco) - More expensive but offers even coverage without loss of performance. Conclusion If you have a weak Wi-Fi signal but a decent router, the RE550 can help, especially by exploiting the 5 GHz band. If, however, the problem is the Internet connection itself or an old router, consider upgrading your main router first.

On my balcony, protected from the rain, it works without any problems. I can't judge it in winter yet, as I've only had the RE550 for a few months.

no idea!

Yes, it is possible to connect the TP-Link RE550 WLAN Repeater to a bbox (or any Wi-Fi router in general). - The RE550 is designed to be compatible with almost any Wi-Fi router and can be easily connected to the router using the WPS button, the TP-Link Tether app or via a web browser. - The connection can be established by pressing the WPS button on the router and then on the RE550 within 2 minutes, or alternatively via the Tether app or a web browser interface.

The TP-Link RE550 device is compatible with most Wi-Fi routers and wireless access points, including those that use 5G frequencies for their Internet connection, but not directly with 5G cellular networks. It can amplify and forward the Wi-Fi signals from an existing router or access point, regardless of whether the Internet connection is via a 5G box or another type of Internet connection. However, it is important to note that the device itself does not establish a direct connection to 5G mobile networks, but merely extends the existing Wi-Fi signals.

Does not work! Sonos only works in the 2.4g network and only if all speakers are directly in the router's wifi.

Theoretically, this shouldn't be a problem, but beware of the drop in speed and latency depending on usage.

I have set it up as an access point with the same WLAN name as the router and the devices automatically switch to the transmitter with the stronger signal.

Good evening. Unfortunately, the answer will depend on a lot of other parameters. For example, is there an obstruction, even temporarily, between the 2 houses? In your configuration, the energy emitted by a repeater is received almost in a single direction throughout the spherical radiation space. Think of your transponder as the sun, a big ball of energy, but only a tiny fraction of it reaches us on earth because the rest is radiated in other directions that are not aimed at the earth. To get round this, we need to multiply the antennas (sources) and also the channels on each antenna. This model works well in a configuration with wave reflections in an enclosed space, i.e. indoors. For outdoor use, unfortunately, you need to go upmarket (more antennas or channels) or install an antenna (or even a repeater) specially designed for outdoor use. There are even directional models that channel their energy in a point-to-point configuration. Don't forget that you need the same type of repeater on each side. Personally, I always prefer to lay a good RJ45 cable whenever possible... In itself, this repeater, which I use more on holiday in the houses I rent out, works well enough but mainly for indoors or just on the nearby terrace. Best regards.

I had bought that one too. It's not worth much. Then I bought this one and am very satisfied. TP-Link RE605X (1201 Mbit/s, 574 Mbit/s)

Hi Sanuya, the difference is the maximum throughput, see RE450 has max 450 Mbits and the RE550 has 600 Mbits. Have fun.

It has a 2-pin plug only.

Yes, that's no problem, but I wouldn't recommend trying to optimise a WLAN with a range extender. That is not optimal. It would be better to invest in a WLAN mesh system and switch off the WLAN in the router. A range extender can't serve devices if they still have a connection, albeit a poor one, at the main router. Only when the main router connection drops completely and you are close to the extender, only then would the range extender take over. A Mesh WLAN, on the other hand, will pass the devices from one Mesh WLAN router to the other without interruption. I would recommend the X20 WLAN Mesh System from TP-Link, it can handle WiFi 6 and covers a very large area. This solution can also use over 100 devices without any problems. https://www.digitec.ch/search?q=tp-link%20x20

The repeater amplifies the signal, for which it needs power from any source independent of the circuit, not to be confused with a powerline adapter (or whatever else they are called) that passes on the signal via the circuit. Think of it as an additional antenna that picks up a wifi signal and amplifies it from there. The fact that your internet is jerky can also have something to do with your subscription (cheaper subscription = slower internet). however, nowadays all offers from swisscom are actually fast enough for normal use, so why don't you check the reception (you can see the filled lines in the wifi sign at the bottom right of the task list)? if only one of the three bars is white and the other two are grey, this indicates that your signal is too weak, in which case you should be helped with this device). With the Tp Link you would also have the possibility to receive a wifi signal (usually a stronger antenna than the one from the laptop) and to plug it into your laptop via cable. I hope you can do something with it :)

You can connect 2 repeaters to the same Wi-Fi if that was the question.

Ja, Stecker ist 2-polig, siehe hier: https://www.tp-link.com/ch/home-networking/range-extender/re450/
