Orbi AC2200 Slow as Molasses

ARGH!!  I replied to all your questions below and posted, but they did not show up on this board!  Here we go again!

Your last tip to disable 20/40 MHz Coexist did the trick!  OOPs.  Spoke too fast.  Back down to crap speeds on the Orbi (<50MBps) after a few minutes.  Whne using the Xfinity wif, get 145 MBps.  Switch back to Orbi and get 40Mbps.

 

What is the Mfr and model# of the ISP modem the NG router is connected too? Arris TG1682G.
Is the Orbi system operating in Router or AP mode? It is in Router mode.

 

You said this is a modem router combo, if so, 

Couple of options,
1. Configure the modem for transparent bridge mode. Then use the Orbi router in router mode. You'll need to contact the ISP for help and information in regards to the modem being bridged correctly.  No option available to do this.
2. If you can't bridge the modem, disable ALL wifi radios on the modem, configure the modems DMZ for the IP address the Orbi router gets from the modem. Then you can use the Orbi router in Router mode.  No option available to do this.
3. Or disable all wifi radios on the modem leaving it in router mode and connect the Orbi router to the modem, configure AP mode on the Orbi router. https://kb.netgear.com/31218/How-do-I-configure-my-Orbi-router-to-act-as-an-access-point and https://www.youtube.com/watch?v=H7LOcJ8GdDo&app=desktop  No option available to do this.

What is the size of your home? Sq Ft? 2,900 two story wood frame.
What is the distance between the router and satellite(s)? 30 feet is recommended in between them to begin with depending upon building materials.  Router to satellite 45 ft.  Router on 1st floor, satellite on 2nd.

 

What channels are you using? Auto? Try setting manual channel 1, 6 or 11 on 2.4Ghz and any unused channel on 5Ghz.
Any Wifi Neighbors near by? If so, how many?  One neighbor 500 ft. away.
What WPA security modes are you using?

 

Try enableding Beamforming and MIMO.  This helped some, but still resulted in 1/4 the speed expected.

Try disabling the following and see:

IPv6 and Set 20/40Mhz Coexistence to 40Mhz only. Save settings and reboot the router and satellite(s).  This did the trick!  Speeds now at 12ms, 135Mbps, 6 Mbs.

My Orbi rounter and satellite are 9 months in operation.  My ISP (Comast) alloted speed is 150Mbps.  I noticed when connected wirelessly to my Orbi WiFi router my speed test (xfinity.speedtest.net) shows a download speed of around 30Mbps or less.  When I connect to the Comcast wireless router (Arris), I get speeds of arounf 140Mbps.  Before suggesting solutions, please consider what I have already done and which produced NO speed increase.

 

1.  Reset/powered off-on my router and its one satellite.

2.  disconnected the satellite.

3.  Checked the firmware revision and it is up to date.

4. Disabled "Daisy-Chain Topology" (saw this mentioned somewhere).

 

Honestly, I am so weary of Netgear hype, followed by my purchases, followed by POOR performance after a short time.  Any help or tips will be greatly appreciated.  Thank you.
