Context
I have recently connected with Sunrise for Internet (Up Internal L) and TV (Up TV L), utilising the coaxial cabling into the building of my apartment. In fact in the apartment itself, coaxial cabling has been installed in the rooms, with six 3-port coaxial wall sockets distributed around the apartment. One is my home office where I have connected the Connect Box 3, and from there I have connected my computer, laptop and NAS with ethernet cables. Other devices in the apartment connect to the Connect Box 3 via wifi.

Challenge 1
At the far end of the apartment the wifi is rather weak, and I was wondering if there is a device I can connect to the 3-port coaxial wall socket available there, to boost the wifi (extender, repeater). Ideally something simple that does not conflict with the Internet Box 3 in my home office. I really just need to have stronger wifi for the mobile devices and iPad that might be used in the bedrooms in the far end of the apartment.

Challenge 2
Similar to above, is there a simple device I can connect to the (unused) 3-port coaxial wall socket in my wife’s home office that would convert the coaxial port to an ethernet one, so my wife can connect her laptop and home computer? Again, this should not conflict or interfer with the Internet Box 3, but rather be an enhancement / extension of the LAN.

In both of the above cases, I am notice there are three different ports in the 3-port coaxial wall sockets (as shown in the image below, and also to the right of step one in this Sunrise installation guide). For any connected devices (as requested in the two cases above), the cables and connectors would obviously need to be compatible with the ports in the wall-socket (I mention this as there seems to be different type of coaxial connectors/ports, though I am no expert in this area).

If someone can assist with some advice here, I would be very grateful.

Thank-you,
Seán.

You have the choice between nothing and the https://www.sunrise.ch/en/support/internet/connect-pods
Alternatively you could wire an ethernet cable by an electrician between the rooms. Here is no device permitted that would put the signal through the existing coax cable.

Alternatively you could use a third party wireless mesh system or a Powerline system, although the latter is prone to problems.

Many thanks for your comment. I was under the assumption that the Internet feed is available through all the coaxial cabling in the house (made available via six 3-port wall sockets), as it is to the one wall socket in my home office. As such, no need for ethernet between the rooms, when I can utilize the coaxial cabling. I was hoping I would just need to be able to connect another device in another room, to convert coaxial to ethernet (in the same way as the Connect Box 3 does in my home office). But are you saying that once the Connect Box 3 is connected to one of the (6) wall sockets, that the other (5) are unusable for Internet?

Best regards,
Seán

Sean_Leahy No, but per contract you only get one Connect Box. You could of course have up to 6 contracts in your case, but you’d also need to pay for each the full price.
There are devices in the USA, which would (ab)use the coax cabling for coax-ethernet adapters.
You are also free to plugin your single Connect Box to whichever room you like.

Okay then I should not think of the in-apartment coaxial cabling as a LAN for carying intenet (or regular computer) data. I guess it only carries TV signal data since the past owner mentioned he used the various wall sockets for televisions and then people could watch different programmes at the same time. I also suppose that the Internet Box 3 acts as a conversion mechanism from the coaxial wall socket so that I can connect to the internet via ethernet and wifi. To duplicate this in other rooms, I would need to buy more Internet Box 3 devices and therefore additional Internet subscriptions, as I understood from your comment above.

Regarding your comment about using coax cabling for coax.ethernet adapters, I saw this online and will do more research. Seems a viable solution in my case.

Many thanks for your support @pato.

Don’t buy such adapters, as they will very probably cause issues with the upstream and might cause issues for you and your neighbours. This might cause Sunrise to completely disconnect your flat from the Coax.

Okay, I will stick with the Wifi for now, and look to Connect Pods if I can set them up in line of sight of each other.

For completeness I made a network diagram of the home LAN.
Room/wall socket 5 pertains to Challenge 1 above, and Room/wall socket 4 pertains to Challenge 2.

In your large home might the Connect Pods or a third party Mesh WiFi set with at least 2 stations quite some sense.
