Advanced Wireless Settings: Enable 20/40 MHz Coexistence
At my office I have a Netgear business class access point. The 2.4 GHz radio has the following three choices via a drop-down for Channel Width: 20 MHz 40 MHz Dynamic 20/40 MHz (I've selected 20 ...
I want to improve speed and range on our 2.4ghz wifi as we have a sprawling one story home and so we need the range as much as we want maximum speed. The 5ghz signal just does not get out very well. I use a windows laptop but we also use a Macbook Pro and two iphones on the wifi. I read a post on this site that suggested that if we have "nearby neighbors" that we might not want to turn off the the 5ghz and go only with our 2.4ghz wifi signal. Our neighbors on both sides are about 75-100 feet from the router.
What is the reason for this advice about not turning off the 5ghz signal and going only 2.4ghz as it relates to "nearby neighbors" and how might it impact them or us in this setting?
Thanks for your input and assistance.
This setting doesn't impact range and coverage however does on performance.
If you have neighbors near by, please try changing to a manual channel 1, 6 or 11, which ever one isn't used alot by neighboring wifi.
You can also lower the output power of the radios from 100% to something lower. This will help reduce your over all wifi coverage if you having issues with nieghbors.
5Ghz is effected by building materials.
Orbi is designed to use both 2.4Ghz and 5ghz radios for its MESH system. It wouldnt' be a MESH system if 5Ghz was disabled.

Thanks but I don't know how to tell what channel(s) our neighbors wifi use.
Also, when you say that it does not impact range and coverage but does impact performance, do you mean it will be somewhat slower?
My router is a N750 WNDR 4300 if that helps.
Thanks again for your assistance.
Do you not have an Orbi system?
Use a wifi scanner...there free. https://www.acrylicwifi.com/en/wlan-wifi-wireless-network-software-tools/wlan-scanner-acrylic-wifi-free
Yes, if it happens that the device has to switch from 40Mhz to 20Mhz, the speed will be slower.

No, I don't have Orbi -- I just searched for Wireless Settings: Enable 20/40 MHz Coexistence and landed in this group. Hope that is OK?
Thanks again for your help.
