The TL-WA850RE (300 Mbit/s) supports WPA3 security only on hardware version V7, as confirmed by the manufacturer's official firmware update notes. For earlier hardware versions, WPA3 is not supported, and the device will only repeat the security mode of the main router, which may limit you to WPA or WPA2 depending on your network setup. If you are unsure of your hardware version, check the label on the device or the management interface for details.
No, crossband is not supported, as it only operates in the 2.4 GHz frequency band. Unfortunately, halving the transmission rate is unavoidable with this model. An alternative would be this repeater: AVM FRITZ!WLAN Repeater 1750E, ac1300/n450 However, it also depends on the router and the client whether you can use the technology.
The compatibility of the TP-Link TL-WA850RE with the Connect Box 3 Ethernet from Sunrise depends on the network protocols and the configuration. The TL-WA850RE supports the IEEE 802.11b, 802.11g and 802.11n standards, which makes it compatible with most WLAN routers. However, there is no specific information on whether it works specifically with the Connect Box 3 from Sunrise. It is advisable to check the network protocols and configuration settings to ensure that both devices work together correctly.
You do not necessarily need an Ethernet cable to use the TL-WA850RE as a WiFi range extender. The device can connect to your router wirelessly, using its Wi-Fi capabilities to extend the signal to other areas.
However, if you want to connect the TL-WA850RE directly to your router via an Ethernet cable to avoid any signal loss and ensure full speed, you can do so. The TL-WA850RE has a single 10/100Mbps RJ45 Ethernet port that allows it to function as a wireless adapter or to connect wired devices.
Good day,
I own this device, but I have never used it together with a switch, let alone with W-Lan and Lan together. Theoretically it should be possible, since a repeater has to manage all clients via W-Lan anyway, it also has to assign an IP to any client via DHCP. In my opinion, the firmware should not cause any problems. However, this problem is not mentioned in the manual, which in turn may mean that the firmware was deliberately saved in order not to compete with other products.
But I have attached the link to the manual. Maybe you interpret it differently.

Ps.: The part is well worth the money, I have never had any problems with it.
