Please provide more 5GHZ wifi channel options - restricting to channels 36-48 is too limiting
I live in London in the UK and nearly every house nearby has wifi and growth of 5GHZ routers is growing rapidly - the WiFI explorer application on my Mac is picking up at least 13 wifi signals on cha...

Please... Let's get the legal stuff straight here for the people who are coming to read this. DFS Law in the US does NOT restrict manufacturors from creating devices that operate in the DFS/TPC bandwidth in Channels 50 - 144. It merely states that DFS SENSING is required on devices that can operate in these ranges. Channel 144 was only *just* added for WiFi use in 2013 with the emergence of 802.11ac, so there is still some ambiguity around the law in other countries. However, in the United states, 5Ghz devices may freely operate in channels 32-48, and 149 - 165 WITHOUT DFS sensing or other restrictions. Furthermore, a vendor may configure their device to operate in the DFS/TPC range so long as that vendor provides DFS SENSING intelligence that can dynamically change channels to prevent interference with government radar systems.
There is a great chart and explanation on the following wiki:
https://en.wikipedia.org/wiki/List_of_WLAN_channels#United_States
I have two old TP-Link access points and a Linksys WRT access point that both allow me to select channels 149 - 165. And you only have to do a little research to find other routers that offer DFS sensing technology that will uniquely change channels "on the fly" to prevent interference. These routers allow operation in the DFS/TPC range, are sold in the United States, and they all comply with the current US laws.
It is obvious that Netgear has decided to forego the more costly solution of adding DFS technology and sidestep the DFS sensing matter altogether by simply not allowing their customers to select any channels above 48 in the 50 - 144 range. And it looks like the other unrestricted range (149 - 165) is reserved for their 5GHz wifi backhaul, so we cannot select any channels in that range either. If they are going to reserve the higher unrestricted channels for backhaul, then they should include DFS sensing technology to allow us to use the channels in the DFS/TPC range. At the very least, allow us to disable wifi backhaul and use the higher, unrestricted channels ourselves.
I freely admit... this is on me for not having done my usual research in the first place. Normally, I heavily vet a new product before I buy, and I did not do that this time. I assumed that this Netgear product would have the same functionality as my older TP-Link and Linksys routers. It does not.
In retrospect, I should have figured that out on my own.The 5GHz backhaul had to go somewhere, and Netgear reserved the higher, unrestricted 5GHz channels for this use. But, the fact that Netgear has taken this route undeniably makes this product less useful for those of us in 5GHz crowded neighborhoods.
I hope that Netgear reads this and at least provides us the ability to disable wifi backhaul so we can opt to use those higher, unrestricted channels ourselves in more crowded neighborhoods. I realize this may not be an option for folks who rely on the wireless backhaul with their satellites. But those of us using wired backhaul should have the option of disabling the wifi backhaul altogether and using those channels ourselves.
Thanks!
