Broad band keeps freezing and is very slow

[Elliesmall]

The broadband keeps freezing and is slow. The emtvs freeze and gaming chips out and the WiFi keeps disconnecting from the mobiles cause the phones to run on data instead of WiFi. Problem has been going on for some time and is getting worse. I have tried to watch one movie and it's frozen multiple times. I turn of the tvs and u  plug I unplug the broad band box but it keeps happening.
