Question about AVM Fritz! WLAN Repeater 450E International

Hello Emu123

This should work. However, I generally advise against WLAN repeaters and recommend using stand-alone access points such as the UniFi AP AC Pro. These have the advantage that they are connected via cable and therefore interference and interfering signals (packets sent twice, etc.) can be avoided. In addition, there is a significant gain in speed, range and stability.

Let me briefly explain how the repeater works: The repeater receives any received packets and sends them out amplified so that they can also be received by the Sunrise Box. If the client (mobile phone, laptop, etc.) is now between the repeater and the router, the router receives the packet directly from the client and again from the repeater, as the latter of course also receives and forwards the packet. Thus the packet was sent twice and valuable resources were wasted. It should also be noted that the repeater must be within range of the router, otherwise it will not work.
If a stand-alone access point is used, the client communicates either with the access point or with the router, but not with both. This allows all resources to be utilised.
In addition, the access point can be set up outside the range of the Sunrise Box, which enables even greater coverage.

This is my point of view on this, if you have any questions just reply briefly ;-)

Hello, I'm opening this thread again because I'm having difficulties with the expansion of my WLAN, unfortunately I'm too much of a layman and have noticed that people here in the forum are happy to help.
I have a similar situation to that already described by Pascal above:
Fibre optic connection with Sunrise Internet Box Sagemcom P/N: 253640407 WLAN router, which offers top WLAN there due to the location of the OTO socket in the Reduit, but unfortunately no more in the last corner of the flat. There are also 6 LAN sockets in the reduit, which are always distributed in pairs throughout the entire flat (unfortunately without PoE, but that's a marginal "problem"). So in principle, as far as I understood from my internet research, it's a good starting point to connect a Unifi AP to the LAN outlets in the rooms. In my case, I have ordered and already received a UAP Lite to expand my WLAN reception at one of the LAN outputs. To do this, I used a LAN cable to connect the Sagem router to LAN socket no. 3 in the kitchenette. In the farthest corner of my flat, I connected the UAP Lite to LAN socket no. 3 (it receives power via the PoE adapter supplied). Then I found the UAP Lite in my wi-fi. From here on, the interaction between the Sagem router and the UAP unfortunately eludes my understanding of IT. I had to set up the UAP via the UniFi app previously installed on my Microsoft Surface, whereby the UAP created a stand-alone WLAN with an SSID+PW determined by me. For me as a layman I now have 3 WLANs: Sunrise 2.4Ghz, Sunrise 5.0Ghz (as far as I understand the clients connect to whichever WLAN they get in better) and the one from the UAP (runs on dual band(2.4/5Ghz) according to the UniFi app).
Now finally my questions:
Can I "mirror" the WLAN (2.4 and 5Ghz) output from the Sagem router on the UAP? If so, what settings do I have to make on the UAP? These are VERY extensive in the app for me as a non-expert,
Does the UAP have to have the same SSID as the Sagem router?
Or do I give the UAP (as already done) any SSID and my clients do the handoff by themselves, or how does it work with the handoff of my clients/cell phones/tablets when I go from the living room to the last room in the flat?
(Note: I am a simple home user without gaming, only up to 2 clients at the same time in the series/movie stream, and it would be fine if the WLAN reception in the entire flat is sufficiently good and even that I can switch from the couch to the last room during a stream without the stream being interrupted).


best regards,
Albert
