A modem allows computers to receive and transmit data over a telephone network. A cable modem allows computers to receive and transmit data over television lines, cable modems are faster than telephone modems. Wireless routers connect to the internet by connecting to modems. There are two types of wifi bandwidths, 5GHz and 2.4GHz. One thing that can block 2.4GHz signals are other 2.4GHz signals, so can microwaves. A solution would be to switch to 5GHz, but 2.4GHz is better at getting a signal through walls. One other thing that can block a WiFi signal is water, which is also why humans can block one, because most of the human body is water. Mirrors can block a wifi signal, which is why a wifi signal
