IPTV channels cause buffering on home network

Can anyone offer any help on this issue please?

 

I have a YouView Humax DTRT1000 box running latest firmware.

 

The issue is, as soon as I start using an IPTV channel, it causes buffering on my internal home network.

 

The Apple TV/Samsung Smart TV from another room will have been accessing TV Shows/Movies from a NAS Drive perfectly fine, but once I start up BT Sport for instance, within a second or so, the Apple TV/Samsung Smart TV App will buffer and never recover. Once I turn the BT Sport channel off, the buffering stops.

 

I should add, the BT Sport channel plays perfectly, it just seems to somehow "block" all other traffic on my internal network.

 

Any ideas/suggestions?

 

Thanks.

Hi,

 

Are you using a 3rd Party Router or any network switches? It sounds like an IGMP snooping issue.

Re: IPTV channels cause buffering on home network

Hi,

 

Yes, I'm using an Asus RT-N66U Router - The Homehubs I tried couldn't deal with most of my IP Cameras.

 

There is also 2 8-port switches on the network (unmanaged?, I think that's how to describe them?) though the Apple TV & Samsung smart TV are both wireless to the router.

 

In fact, both those devices are connected to a Range extender.

 

I might in fact, have somehow solved this myself - I tried switching both the Apple TV & the Samsung Smart TV from the 5ghz Extender signal to the 2.4ghz band, and the buffering seemed to have stopped. Though i only tested this morning for 10 minutes, usually, i wouldn't get 5 seconds before buffering.

 

If it is IGMP snooping, where should I start looking to fix things?

 

Thanks again for your reply.

Re: IPTV channels cause buffering on home network

I think that first thread is the ne I used when i replaced my HomeHub & found out that BTs IPTV wouldn't work with a lot of routers.

 

That's not the issue now though. The IPTV channels play fine, but just seem to block the rest of my network whilst they're playing.

 

Will take a look at the blog post though. Thanks.

 

 

**EDIT**

 

Hmmm, that blog is way above my knowledge level. Whilst I know enough to throw together a relatively simple home network, I'm afraid that is way above my station.

With regards to the switches, I'd suggest either having the STB hard wired directly to one of the ASUS ports, or getting a switch which supports multicast and IGMP snooping.
