I upgraded to Kongac 39960M 6/8/19 and for some reason checked the speed of the wifi. Using Acrylic Wi-Fi scanning software it shows the 2.4Ghz for the Netgear 7000 is only capable of 216.7 Mbps.

I have tried changing 40 Mhz without any change. Yet if I have tried fixing the channel to 1 or 11 and no difference. If I enable the Wifi on my ISPs Sagemcom Broadband SAS router its 2.4Ghz shows its speed as 600 Mps.

The R7000 is simply acting as AP with its WAN port disabled and is connected to my wired router

Is this speed slowness a known issue on the R7000 router?

216,7 is the speed for 20 Mhz channel width

Make sure you have set to 40 MHz channel width, auto channel never works, to set a fixed channel toggle upper/lower while saving, so that you can set a fixed channel.
Make sure security is set to WPA2/AES
Reboot after changing and check if channels are set.

This router should be able to get 450 Mb/s theoretical speed (one stream at 20 Mhz is 72 Mb/s, for 40 Mhz width this is rounded to 150 Mb/s, the router has 3 streams (3 antennas) so that makes 450 Mb/s.
Real life throughput under optimal circumstances is 2/3 of that. But of course your client also has to support 3 streams (have 3 antennas), a lot of clients only have 2 streams.

Thanks for the information. Strange that I had tried all those settings before and it still showed 216.7 but tried it again and it is now showing 450Mbps.

Thanks again. Smile
