Connection problem

Hello, thank you for your very quick response! I’ll try to detail it, but I’m not very good at technical topics… So we have the internet box at the top, connected to the 1st TV box. A first antenna leaves the internet box (it’s a kind of U), it is connected to it by a cable, Ethernet I believe. Two floors lower is the 2nd tv, with a tv box and the antenna receiver, the (almost) same white U also connected to the tv box by an ethernet cable… That’s what ’we always (well in the premiere version of swisscom) had. Since 2.0, following a renovation and a slight change in furniture configuration (we can no longer put it back exactly as before), the Internet has no longer worked well in the house. We were unable to watch TV downstairs, even in normal quality (non-HD), recordings and viewings from previous days, nothing worked. Following some research on the web, we decided to buy a kit to extend the wifi in the house (we bought the Devolo dLAN 500 WiFi Network Kit system with 3 practical devices given the number of floors that needed to be served …). I plugged it in: the first connected to the internet box on the top floor (4), the second into the socket in the living room where the second TV box is located (but not connected to it) and the last into a socket on the basement. The TV now works well, I suppose it runs in HD, since it no longer constantly asks us if we want to see the programs in HD version. The problem is that it is no longer possible to surf while someone is watching TV. I suppose that the tablet which has the access code to the wifi of the devolo system can be connected directly to it and suddenly the TV is in the second place… Perhaps by connecting the tv box with an ethernet cable directly using the devolo adapter instead of the U antenna, that would solve my problem… But I also read that these systems should not be plugged into multiple sockets… Is there any risk for the tv box… Honestly I don’t know, so if you can help me that would be great! Thank you in advance… Fabienne

Good morning,
I connected the dlan 500 to the internet box (router?). Moreover, the tablet recognized the “new network”: I managed to connect it to the dlan using the new wifi key available with the adapter…
The dlan works… well?! In any case, I can surf and listen to the radio… And all this while being connected to this “new network” (my tablet, my phone etc. are no longer directly connected to the home WLAN network, a network which still remains available in the list of desired networks The problem occurs when I watch TV and I try to load an internet page, then the TV stops… Sometimes it starts again, sometimes I have to turn everything off because it has lost. the network… And when the two tv are on, it’s even worse…
Thank you for your response

In fact, the TV is not directly connected to the dlan, it still has the old antenna provided by swisscom several years ago, so I wonder if I should replace this antenna with a direct connection with ethernet cable au dlan… and in this case, the internet adapter would be plugged into a multiple socket and I had read that these adapters lost a lot of their effectiveness in multiple sockets…
(In parentheses, this new arrangement where all my sockets alone, at man’s (or woman’s) height, are used for these damn and not very nice adapters, poses a lot of problems for me for my vacuum cleaner, our phones and tablets to charge. ..)

Hello, thank you for your response, but this is not the equipment I use. In fact, I have a device that allows me to “expand” my wifi network, but my box is connected as before by ethernet to an antenna provided a few years ago by swisscom…
On the other hand, my problem is really a kind of overload: when I use only one device at a time, it works, but in a family with 3 children, it’s not enough!

Thanks for your help everyone! So indeed the antenna that swisscom provided us looks like a ruckus, however, it is not wireless. An Ethernet cable therefore connects this antenna and my TV box

So the antenna is a ruckus type as said above, but with cable
