Significant Drop in download speed cbr750
CBR750 — Orbi WiFi 6 DOCSIS 3.1 Mesh WiFi Cable Modem Router
Firmware version V4.6.3.6
App version 2.11.0.11
In last two days, my Download speed dropped from between 1200-1400 to 500-600. Had this model since March 2021 and first time a download speed drop has persisted more than a few hours. Tried calling support and they provided basic advice and had me change a couple settings and said everything else looked okay and to give it 24 hours. The drop seems to have started happening right after I installed the last firmware update. I called ISP (xfinity) and they said everything is fine on their end and they are sending 1g speeds. I paid $1k for the modem router combo plus two satellites and netgear tech on the phone says I need to pay a subscription if I need advanced help. I am so disappointed. Has anyone else experienced a slow down after latest firmware update?

How are you speed testing? Wired or wireless?
What devices are you using to speed test with?
What is the size of your home? Sq Ft?
What is the distance between the router and 📡 satellite(s)? 30 feet or more is recommended in between RBR and RBS📡 to begin with depending upon building materials when wirelessly connected.
https://kb.netgear.com/31029/Where-should-I-place-my-Orbi-satellite 📡What channels are you using? Auto? Try setting manual channel 1, 6 or 11 on 2.4Ghz and 40 to 48 channel on 5Ghz.
Any Wifi Neighbors near by? If so, how many?
Is Armor enabled?What CTS values are currently set? Under Advanced Tab/Advanced Settings/Wireless Settings
Have the ISP check the signal and line quality UP to the modem. Be sure the ISP provisions the modem correctly.
Be sure there are no coax cable line splitters in the between the modem and ISP service box.
Be sure your using good quality RG6 coax cable up to the modem.
Be sure to power OFF the modem for 1 minute then back ON.
https://community.netgear.com/t5/Cable-Modems-Routers/General-info-and-Troubleshooting-for-Cable-Modems/m-p/1530376#M12853- 2700 sq ft, two satellites. Really everything has been amazing up until I installed latest firmware. The locations of my satellites haven’t changed and good distance apart. The satellites light up as expected, no yellow or pink lights. They are not blinking either. I am having an xfinity tech come out to check my cables inside and out to rule out ISP since it is a newer construction community.
I do the speed test on a computer hard wired into the main orbi and on my phone sitting a foot away from main unit. This didn’t happen before and never had to tweak my settings. Both ways as of right now give me less than 600. Before this issue, I could pull 1200+ MPs on my phone ANYWHERE in the house until a couple days ago so something is up. Will check those other settings and reply shortly. I am not hooked up for armor but I periodically check to make sure the devices connected to my network are good and I change my internet password every six months. I purchased the orbi products to not have to pay Comcast a monthly fee to rent equipment. If I start paying for armor and Netgear customer service I might as well pay xfinity since it only costs 15 bucks a month and they provide all that security stuff. When xfinity comes out today I am going to have them hook up one of their modems to check speed. This will tell me if it is my orbi is causing my issue. Again no problems since Install and have had it since March 2021. Hoping this is just an xfinity issue.
How many devices can I hook up to to this product? I currently have 32 devices. This has also not changed and if anything I had more hooked up last month with no issues.Are you speed testing using the built in speed test app on the RBR or with a external speed test app on the PC and mobile device?
I presume this is a FW issue that seems to stem on this v4 version of FW as we are seeing similar behavior on the RBK7 and 8 series which the CBR750 is based off of.
I am in the same situation!!! Prior to CBK 752 Firmware updates (CBR750 -V4.6.3.6, RBS750 -V4.6.3.7) was consistently getting 1.2gb - 1.4gb download speeds. Now it below 650mb. Nothing else, besides the firmware updates, has changed.
Netgear Team - Kindly review firmware and provide a fix!!!
Please open a support ticked with NG support and let them know what your experiencing. Can reference this forum thread as well.
Thank you.

- I also have this se speed drop. Was regularly getting 1300-1400 down and now topping out at 600 after the update. I am testing speed at router login as the app is all but useless because it does nothing but crash. Ridiculous that I can not roll back to the previous firmware either. Please fix netgear!
I have the same issue with the same software V4.6.3.6. The software was downloaded by Xfinity on 8-13 and I saw my speeds drop from 900+ down to 600. This needs to be addressed by Netgear and Xfinity.
Well, at least you were lucky to have had close to or above 1000Mbps -- my average is 600 Mbps probably because I updated the firmware as soon as I got the CBR 750 -- probably should have checked this thread before doing that. I called Xfinity, and they said that everything looked ok on their end. I was getting 980 Mbps on Xfinity's white Technicolor WiFi6 cable modem when wired. This is highly disappointing since I am paying for 1200Mbps service and getting half of that.
Wait.... just tested by going to the speedtest.net site and got over 900 Mbps -- hmmm....maybe it is an app and web interface problem with Orbi.
I thought it was strange that I was getting over 600 Mbps on my iphone from the satellite connection while my wired to the CBR 750 connection was the same or slower than that.
I am not sure what is going on, but I will test this again in the next few days and try to determine whether the ethernet connection or the speed calculations are wonky.
I am still frustrated with this situation.Yes I can pull 900 + hardwired but I have a significant dropoff in speed on wireless that was not the case before the firmware update. I also see that my wireless devices are now ignoring the satellite and staying attahed to the CBR750. Only one or two devices connect to the satellite, the ones right next to it, while before this update I usually had 10+ devices connected. I am on Comcast and see that the Cox folks got a new version pushed to them. I hope Netgear is working with Comcast also for a quick resolution to these issues.
Same exact issue over here what the hell, making me instantly regret firmware update.
At least im not the only one...
- I have an Orbi 850 with Xfinity gig plus. When I upgraded to the new firmware I to went from 1100-1300 down to 800-900.
I checked with Xfinity and this is definitely a Netgear issue. Anyone gotten a response from the as to a fix?Netgear has set up a community forum specifically for the Orbi AX (WiFi 6) products. Most of the people who watch that forum are more likely to have experience with Orbi AX and know how to work it better than those of us who follow this "Orbi with Cable modem " forum. Might be more likely to find someone who has a solution if the question is posted there:

- Another day of all day dropped signal while I was at work. Got home, reset it. Worked fine since. This is getting annoying!
- I was able to upgrade my RBS 750 satellite software today from the Netgear support page. Neither the CBR or RBS were showing a upgrade available through the web interface.
This drop in speed is a known issue and has been going on way to long! I sure hope we see a CBR 750 upgrade that fixes this soon, but I am on Comcast and they seem to be very slow at updates.
If nothing changes by end of year I will switch to T-Mobile home internet when my contract is up. I will not pay for speeds I am not getting through the CBK 752 Orbi system.
What NG Orbi model do you have?

I have fixed this by switching my main Orbi to AP mode then back to router mode. It did a reset by itself and now the speed are back up to normal after 4 weeks of slow speeds following the update.
