В итоге у клиента показывает малая часть IPTV каналов и со временем всё меньше. У клиента стоит роутер TP-Link 841. ИПТВ смотрят на МАГ-250. У других то же самое работает отлично. Роутер менялся, у клиента 3 приставки. У других и 4 приставки тянет нормально. Проблем не замечалось.

Что тут не понятного.

На группу 231.195.0.15 два подписчика - на 49 и на 8 порту.
