I installed the Blue TV app on my iPhone, I connected with my Swisscom account, the connection was successful but the message “Oops, an error has occurred. Please try again later.” appears each time I try. I am naturally subscribed to Swisscom Blue TV which works very well on my usual box. What should I do. I am connected to the internet via a WiFi network but the problem is the same on a 4G network.
Sorry if this issue has already been resolved many times.
However, I started (as I always do) by looking for a solution on the forum with keywords like Tv Box No WiFi AirPort UHD etc… without success. (I notice that retyping it now I still find nothing other than… my own post.. Which is already a good reason for asking this question for the xth time, since the others seem so poorly indexed. .. 😉
And I noticed that after 24 hours I had not received the slightest response, whether from a Swisscom manager or a user…
But if the problem has already been solved many times, this at least proves that it is common and that therefore the documentation provided by swisscom with the TV Boxes would benefit from mentioning the problem… Even if the average user in an apartment connects certainly its TV Box directly on its input router (or via WiFi), the use case that is mine is certainly not in any way exotic…
And regarding the explanation of the “User Forum” I note that this forum is hosted on the Swisscom website and was created by Swisscom. It’s true that it’s so much easier to let customers do the technical support themselves rather than devoting the resources needed to help paying customers who run into unexpected but common problems like this. ..
And I saw several posts responded to by Swisscom managers… Especially to promote new products, such as the advent of UHD at Swisscom before the competition… Certainly… 😉
Good. Since no one responded to my query, I had to resolve it myself. (Now that I understand the problem, I am surprised and disappointed that no one - especially from Swisscom support - has filed an answer here because I think the problem may occur in many Swisscom TV customers with a local network cable and a WiFi hotspot at their home and that Swisscom technical services should therefore warn their customers against this problem…)
So here is the cause of the problem I identified and its solution:
My network is made up of the Swisscom entry router (located in the basement, where the Swisscom telephone line arrives) from which several subnets are deployed from its various LAN outputs to each floor of my house. On each floor, a switch distributes the LAN to the different rooms or the various devices (computers, TV Boxes, etc.) on that floor. This architecture is naturally classic for any Swisscom customer who has wired a LAN at home. So I must not be the only one or the first to encounter the problem.
Naturally I also set up a WiFi network. Since the Swisscom entrance router is located in the cellar, I do not use the WiFi hotspot included in the Swisscom router, because the signal would be poorly received in all rooms of the house. So I placed a separate WiFi hotspot (an Apple AirPort) on the first floor, right in the center of the house so that its signal was well received everywhere. It is connected via its WAN input to the local network and broadcasts over WiFi all the network traffic it receives from the LAN.
When I plugged my Swisscom TV Box v2.0 UHD into a LAN connection (from my WiFi hotspot) all the Multicast traffic from the Swisscom video stream (coming from the LAN output of the Swisscom input router and sent to the TV Box) was was reflected on the WiFi network by the hotspot and apparently saturated the latter. Result: No more WiFi available…
Solution:
Use modern switches/routers implementing the IGMPv3 protocol (IGMP Snooping).
This makes it possible to only route the video stream traffic (transmitted in Multicast) to the device for which it is intended (in this case the destination TV BOX) while avoiding flooding the entire LAN (and WiFi). ) with this high bandwidth traffic (40Mbits/sec in UHD, 10Mbits/sec in HD). So I added a switch implementing IGMPv3 (a Netgear GS105E v2.0 ProSafe Plus 5Ports) upstream of the WiFi hotspot, and I connected the TV Box 2.0 UHD and the hotspot to two different outputs of this switch. (An ordinary switch - e.g. a NetGear GS105, which I used before, or the one located on the AirPort hotspot itself on its LAN outputs) not implementing the IGMPv3 protocol, it copies all the Multicast frames received on its input to each of its outputs, thus flooding the entire network (including WiFi) with unnecessary traffic for all recipients excluding the destination TV Box…
The other solution would have been to plug the TV Box (directly or indirectly) into another LAN output of the Swisscom ingress router than the one that routes traffic to the WiFi hotspot because the Swisscom router naturally implements IGMPv3 filtering.
I naturally took the opportunity to also replace all my other switches with switches implementing IGMPv3 so that my other TV boxes (I have 4) do not cause unnecessary traffic on the LAN. (They had not shown the problem until now because they were all connected to another output of the input router than the one which supplies the WiFi hotspot…)
I would like to point out that my WiFi hotspot is a first generation Apple Airport Express. I don’t know if the newer Apple WiFi hotspots (Airport Express second generation, with a single LAN output or the Airport Extreme) implement the IGMPv3 protocol. In any case, if you have wired a LAN at home with switches distributing traffic to your Swisscom TV Box(es), I recommend that you only use switches implementing the IGMPv3 protocol in order to limit Multicast traffic from video streams from Swisscom only on the strands that route traffic to your TV Boxes.
I hope this explanation will help other users and I thank Swisscom for their technical support… 😉
Good morning,
I bought a fourth TV Box (2.0 UHD). I already have 3 old generation 2.0 TV Boxes (non-UHD) on my LAN and which work perfectly. I have a Wifi hotspot (Apple Airport) upstairs, also connected to my LAN and which works perfectly when my new box is turned off! As soon as I turn it on, I can no longer connect to my WiFi!
The Swisscom entry router is located in the cellar (where the twisted pair of the Swisscom network arrives). The Airport WiFi hotspot is upstairs and is connected via its WLAN input to a LAN output of the Swisscom entry router via my 1GBbit Ethernet LAN network.
The new 2.0 UHD TV Box was also upstairs, so I connected it directly to one of the LAN outputs of my Airport WiFi hotspot. (As I did for a PC without it causing any problem on my WiFi network).
Note that the 3 other TV Boxes (non-UHD) are not connected to one of the LAN outputs of the hotspot, but directly to my LAN. They don’t disrupt my WiFi.
Has anyone ever observed this type of problem when plugging a TV Box into a LAN output of a WiFi hotspot?
How to solve it?
Should I connect my new 2.0 UHD TV Box directly to my LAN upstream of the hotspot? Or even on another specific LAN output of the Swisscom entry router? (Which would require me to lay an additional ethernet cable to the cellar).
Is there any special configuration I need to do on my router or hotspot?
Anyway, am I getting lost in conjectures?
I have a VIVO M subscription at 100 Mbits, Swisscom TV 2.0 and Swisscom telephony.
Thank you for your help.
