Channel 1 operates at a center frequency of 2.412 GHz. Channel 11 operates at 2.462 GHz. Other channels operate at frequencies in between, evenly spaced at 5 MHz (0.005 GHz) intervals. Wi-Fi gear in Europe and other parts of the world also supports channels

I am confused as to why the least expensive one has more channels compared to the “better” one. And also curious with which channel is best to use and what the difference is if I pick a lower channel compared to a higher numbered channel.

The channels that your “better” router has omitted are what is known as the dynamic frequency selection or DFS channels.最佳回答 · 21The best channel to use is the lowest channel that has a high transmit power. Lower frequencies penetrate walls more easily, and there is a signifi7Your “better” router probably supports that fuller list of channels as well, but it doesn’t show you those channels for manual channel selection. A6To answer the other half of your question, channels 149-161 will provide better range than 36-48. The higher band broadcasts at a stronger signal t3If you are in a house where your wifi needs to penetrate multiple walls and/or floors – choose a low channel. If your in a loft apartment or want y0

All channels on your 5GHz band will deliver the same bandwidth as well as speeds. (Please note that this is different if you use channel bonding.) The only way to pick the best 5GHz channel for you would be to choose the one which offers the least amount of

Channel Bandwidth for 5GHz The 5GHz frequency can support the wider channel bandwidths, which means not just the 40MHz, but also the 80MHz and even the 160MHz channel bandwidth. Not all routers are capable of the 160MHz or support it, but it can be

Most dual band devices that support both 2.4GHz and 5GHz will automatically pick a band based on different factors like signal strength. Another friendly reminder: Your Wifi point(s) uses the same network name for both the 2.4 and 5GHz bands.

The big appeal of 802.11ac is higher bandwidth, which will be accomplished in first generation 11ac products primarily through the use of wider 80 MHz channels. Channel planning in 802.11ac also involves assigning primary channels to allow for dynamic per-frame
