So thanks to my service provider I'm able to watch some TV channels through the computer, using software (VLC, ffplay, MPlayer, etc) that is capable of playing multicast UDP streams. My problem is that the playback of these channels is only possible via wired connection. I was wondering what might be my options to make these channels also accessible through WiFi?
I guess one way is to restream it, so that if someone wants to watch the channel, I'd have to turn on the desktop computer and start restreaming it to the network. But I don't see it as a very good option. Are there any other options?

Ok, so I was asked to add additional details about my router. It's Thomson's 789vn with software version of 8.C.D.5. For a temporary solution, I am just restreaming the stream if someone wants to watch it through a WiFi-device (smartphone, tablet, laptop, etc). The problem is, that for this I have to have at least one computer powered on, that has a wired connection. And then on this computer which has a wired connection, I'd use the command:
vlc --intf dummy udp://@239.3.1.2:1234 :sout=#http{mux=ts,dst=:8080/} :sout-all :sout-keep
And then the WiFi-devices are able to watch the stream by opening the network stream in VLC corresponding to the IP, for example http://192.168.1.20:8080
.
But what if my desktop PC is turned off and I'm so far from it to turn it on. Or if it's turned on, how I could remotely start the "sharing" of the stream?
Please include more details (make and model) on your WiFi AP/router in your question. – Daniel B – 2015-03-21T13:16:27.093

Unfortunately multicasts are very expensive on Wi-Fi, making this a bad idea. Multicast packets on Wi-Fi must be sent at a low data rate so everyone can receive them. This wastes a lot of airtime (bandwidth). Multicasts are also buffered for short periods of time and sent all at once (DTIM interval), potentially causing jitter for real-time A/V streaming protocols. For best results, keep your clients close to the AP so you can set your multicast rate high, set your DTIM interval to 0, and disable power save mode on ALL client devices. I strongly advise against Wi-Fi multicast streaming. – Spiff – 2017-08-31T18:10:49.387
