The times when wireless breaks multicast is when people replace the ISP supplied router and that does not support multicast

Honestly give up and run some Cat5e. A quick check on eBay shows you can get a 30m patch cable for £5 delivered.

The cost isn't necessarily the issue - not all houses are suitable for running wiring like that, it could be a rental that doesn't allow it or it could be the only sensible route is surface mount which may not be an option (I hear some houses have an optional extra that makes this impossible to do - I believe they are often called "the wife").

I bought some flat ethernet cable, and routed it out through the window, and round the outside. It is thin enough to squash through the rubber seals easily.

Some clear plastic command-strip clips (the type meant for christmas decorations) keep the cable in place when the windows are open.

The only downside is that is internal cable, so UV will wreck it eventually. It is still going after 2 years, though.

Inside the room, I have used some shaped conduit, laid against the bottom of the skirting. This is enough camouflage to pass the SWMBO test.

Or they have a dog/cat that loves to chew anything & everything..... Mine love any sort of cable they can get their teeth into.
I installed cable under the floorboards, but you still have the run to the device which are a prime target when your back is turned....

How sure are you on this?

As in I tried 3 wireless adapters on BT TV and could not get BT sport and other channels to work.

AFAIK BT Homehubs have never sent multicast over wireless.

The only way this has ever been achieved that I can see is where users put a wifi device into the home hub over Ethernet, then connect to this with another wifi bridge at the other end.

You will note using a bridge as suggested will only give access to catchup and iPlayer not multicast TV channels.

Mmm if the router is splitting traffic and not sending the multicast over Wi-Fi then any adaptor won't work.

Yep that was my experience.

Some users take a wireless access point, connect it to the homehub via Ethernet, name it something unique. They then place another wireless bridge where the BT TV is and connect it to the unique SSID. Apparently this did work ok for some, but quite a messy setup.

Never plumped for BT TV in the year I had the service so never got to play around, change the TV viewing connection at end of every contract...someone has to test migration processes
