Bandwidth has the same meaning of capacity, and defines the data transfer rate.īandwidth, though, is not a measure of network speed.Īs a matter of fact, the words “bandwidth” and “speed” are often misused as synonymous.

Network bandwidth is the capacity of a network communications link to transmit the maximum volume of data from one point to another over a computer network or Internet connection in a given amount of time, usually one second. The same action takes a few seconds instead if the connection is broadband, like the one with the optical fibers (over 1000 Gbps). For example, a low definition video lasting 15 seconds, weighing 1 Megabyte, can be downloaded from an Internet site on your computer in 3-5 minutes if the connection is made via modem (56 kbps) or ISDN line (from 64 to 128 kbps). The unit of measurement is the bits per second (bps). The bandwidth determines, therefore, the number of bytes that can be transmitted on the connection. The basic unit of this language, the byte, is composed of 8 bits. During the transmission, the information is sent in a binary system, a language that encodes data using only two symbols (often defined as “1” and “0”, or “on” and “off”), each of which is called a bit. Utilising Ethernet to connect Sky boxes frees up the most valuable and most reliable 5 GHz Wi-Fi spectrum for your Wi-Fi network.Bandwidth is the capacity of a channel to transmit data. With Sky utilising all four so-called non-DFS (Dynamic Frequency Selection) channels, you would be forced to use DFS channels for your own Wi-Fi network, which could fail to operate if radar is detected. These channels are particularly valuable in the UK since they are the only ones where there is not co-existence with radar systems. Sky actually recommends that the Sky boxes are configured to use wide 80 MHz channels (taking up four 20 MHz channels – 36, 40, 44 and 48). Particularly if you use multiple Wi-Fi Access Points (where different channels should be used with each one to minimise interference), freeing up the 5 GHz bandwidth used by Sky boxes will be very useful.
#HOW TO CHECK WIFI CHANNEL USAGE INSTALL#
In general, when Sky engineers install Sky Q boxes and/or install additional Sky Q Mini boxes, they configure them to have wireless switched on (both 2.4 GHz and 5 GHz). Wi-Fi scanner applications such as NetSpot, inSSIDer or WiFi Scanner can be useful to check that Sky boxes are no longer using Wi-Fi and are using the Ethernet connection itself. We have found that Sky boxes can be a bit temperamental and turn Wi-Fi connections back on in some cases. Make sure you turn off both 2.4 GHz and 5 GHz and select ‘Confirm’.

You also have the opportunity to set the channel(s) used by the 5 GHz Wi-Fi. Here you have the options to separately turn 2.4 GHz and 5 GHz wireless on or off. The message “These settings should only be changed if you’ve been instructed to by Sky” will pop up.

When you arrive at ‘Settings’ please do not press the enter/select button.Įnter the sequence 001 and press the enter/select button. Press the ‘Home’ button on your Sky remote control. Make sure you have connected Ethernet cables to your Sky Q and Sky Q Mini boxes (and ensure these are connected to your router).
