Slow WIFI on RBR850

Hi. I have a RBR850. Getting 1gbit/1gbit hard wired. Only getting 360 mbit wifi.


What Firmware version is currently loaded? V3.2.18.1
What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too? No modem
What wieless device are you using? iPhone, Rasperry PI, Tesla

What are your wired speed results with a wired PC or laptop? 955 mbit / 978 mbit

 

What is the size of your home? Around 128 sqm
What is the distance between the router and satellite(s)? 10 meters

What channels are you using? Channel 1 for 2,4 48 for 5 GHZ
Any Wifi Neighbors near by? If so, how many? Around 15

 

Try disabling the following and see:
Armor, IPv6 and Set 20/40Mhz Coexistence to 40Mhz only. Set Short preamble instead of Long preamble modes. Save settings and reboot the router and satellite(s). I did disable Coexistence, I did set short. Disabled IPv6 and armor. Cant set to 40 MHZ. Cant see that option.

 

Please advise.

Re: Slow WIFI on RBR850

Wifi speeds depend on connection rate, MIMO antenna support and OFDMA which Orbi AX doesn't support from what I was told. 

Most phones and pads are 2x2 MIMO antenna design and max out at anywhere from 300-500Mpbs on wifi. 

Connection rate depends on the connection support by the device and the host wifi router. AC rates max out at 1733Mpbs and AX is 2400Mbps on 5Ghz, Depending on support and design of the host router.  https://kb.netgear.com/19668/Link-Rate-and-Transfer-Speed

 

I've seen my iphone 12 max get around 500-600mpbs. My Mac Book pro 2018 has seen 700Mpbs with Orbi AX. Using a non NG orbi mesh system, I've seen my iphone get around 900Mpbs however that system supports OFDMA.

What are you connection rates seen on the MBP at the RBR with RBS turned OFF?

Re: Slow WIFI on RBR850

What are you connection rates seen on the MBP at the RBR with RBS turned OFF? This is seen on the wifi connections list when you press the option button on the MBP and left click on the wifi icon on the top tool bar of the screen.

Re: Slow WIFI on RBR850

Do you have Traffic Meter enabled by chance on the RBR? 

 

For setting 40Mhz only, just take the check mark out of the check box for 20/40Mhz Coexistance and this sets 40Mhz only. Apple the change. 

 

How close are you to the RBR when speed testing? 6-10 feet range? 

Make sure Enable WMM is enabled and try setting 2347 for CTS. Under Advanced Tab/Advanced Settings/Wireless Settings

Re: Slow WIFI on RBR850

Just checked mine when I got home. 1Gb/50Mbps ISP service.

v1 FW. 

Manual channels 11 and 48. 

40Mhz only. 

CTS 64

Armor and Traffic Meter not enabled.

WMM enabled. Preamable Mode: Auto

Mac Book Pro 2018 placed near the RBR, 4 ft:

Screen Shot 2021-05-25 at 4.34.14 PM.png

 

Checked my Iphone 12 Max as well:

Pretty good for sitting right next to the RBR. I presume as distance gains in between the devices, speeds will have some degradation which is to be expected.

Re: Slow WIFI on RBR850

Have a different laptop to test with? 

You might try downloading v1 FW manually using a wired PC on the RBR, factory reset and test again...

Possible your RBR is faulty.

I'd make contact with NG support and get additional help on this. Possible you have a faulty system.
