✎ DSL service must use the DSL modem; and cable service must use the
cable modem. Since only a limited number of network connections may be
available, TV network setting may not be used depending on the contract
with Internet service provider. (If the contract does not allow more than one
device per line, only the already-connected PC may be used.)
✎ Wireless network can experience interference from other devices with 2.4
GHz frequency (wireless phone, Bluetooth device, or microwave oven).
Interference may also be caused by devices with 5 GHz frequency, the same
as any other Wi-Fi devices.
✎ The surrounding wireless environment can make wireless network service run
slowly.
✎ Failure to turn off all local home networks may cause excessive traffic on
some devices.
