I tested beta 3.0 and it works ok but there is a lot bugs.
but there is still an old problem on Beeta 3.0 , the other problem is QoS and IPTV app on my tv, IPTV App on my Samsung doesn't work until QoS is turned off.
When QoS is turned on, all devices where I have the application with iptv installed do not work, and when QoS is turned off, all devices on which IPTV is watched work properly.
it is not clear to me that it works perfectly on other routers, and that it can't be fixed on XR500 for a very long time.
