I bought this router as it supported multicast, which I needed for my BT TV box.
I followed the procedure (as posted on KITZ) to set it up for BT TV multicast services and it all worked fine.
However, following an upgrade to a new BT TV UHD 4K box I now have a big problem.
The BT UHD 4K channel isn't working, the router, it would seem, simply can't keep up with it.
Lots of sound breakup and picture freezing is the result, but only on the UHD service, HD services are still ok.
I tried updating the firmware to the latest available, AAKL.16C0, but there's no improvement.
I've also tried the alternate method suggested by a few people of setting up the router by allocating a port, but all to no avail.
I have good VDSL speed (over 70mbps on an ECI cabinet) and my old BT Home Hub 5A handles the UHD service without any problem.
Has anyone else had this issue, and more importantly managed to solve it, as the HH5A is woeful in every other respect.
If anyone has successfully used the KITZ setup without a problem for the UHD service could you post your version of Firmware please.
