I don't know, because my son has the device. Best regards

Basically works with any device that needs the listed radio and encryption standards. I use it myself with a Swisscom router.

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.

What is the status of the LEDs on the tp link box?

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.

The speed depends on the quality of the WiFi received. If the reception is by Ethernet cable, there's no problem, but it works very well!

A WLAN repeater can connect to any hotspot. This one simply supports 2.4GHz.

I think no

no

Unfortunately, I don't know. Greetings and have a good week.

It would work, but in practice PowerLines are generally more recommended. https://www.digitec.ch/de/s1/producttype/powerline-1233?q=powerline&tagIds=7

My son thinks it is very good. He is satisfied.

Yes, the repeater can also be operated as an access point and then creates its own WLAN, for which a LAN cable must be plugged in at the bottom.

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. http://static.tp-link.com/TL-WA850RE(EU)_V4_UG_1478154293609k.pdf Ps.: The part is well worth the money, I have never had any problems with it.

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.
