CBR750 Fails after firmware update
I recently updared the firmware on my Orbi CBR750 to the latest v4.6.3.6_2.0.48 update. I can no longer establish internet connectivity. Prior to updating my connection was fine with no issues. My ISP says nothing is wrong and the Netgear tech support is no help considering I'm outside my 90 day purchase window.
The cable connection error is with the cable connection continuously failing to connect. I've used new cables and moved it to other cable ports in the house known to work in the past.
Please help.

ORBI is back online in San Diego. Latest firmware V4.6.3.6_2.0.48 is running with no hiccups. Now to get COX to refund my $75 service call charge.
I hope you get a refund. The Cox Tech that tested my line and confirmed it was an Orbi CBR750 issue had my service charge waived so it was no cost. Now if things are truly fixed, later today when I can, I will have my Orbi provisioned again to test it out, but I am still hesitant.
All,
I just went the the NG web page or firmware downloads and documentation. Firmware version 4 has been removed. https://www.netgear.com/support/product/CBR750.aspx#download
FW was removed from support website for abudance of caution since the root cause was not clear.
Now that problem has been rectified by ISP, we will work through to get new FW back (we will let things stabilize to make sure there are no new cases).
change was in CM boot file where ISP was doing changes for network and the CM Boot file for this model was errorneously coded.
VkDelta, Well up and running now in the Fairfax County, VA area on Cox. Just had the CBR750 reprovisioned and all is working. With the start of school this week, I was getting hammered by my wife and daughter to get the internet working. Especially with all the school stuff online these days, no one uses real books anymore.
Regards, Rick
Thank you to everyone who commented bringing attention to this issue! I can proudly say my CBR750 is operational once again. A special thanks to the NETGEAR employees who never gave up hope even when a few of us had thrown in the towl.
Be sure to save off a back up configuration to file for safe keeping. Saves tine if a reset is needed.

I have a CBR750 with firmware Version 4.6.3.6.
Orbi Android App V 2.11.5.1716
After updating to the latest level of firmware last week, I've had consistant drops in service. My ISP (TDS) says there is nothing wrong on their end, yet my Orbi cable modem keeps losing signal. I'm in the same boat as you guys. I've read a lot of this thread and will try the ways you all did before I escalate to NG. Thank you for all the replies.
Contact NG support regarding your CBR750.

Hi Dellaman87. I started this string I believe close to a month ago and last 2 weeks spent time on several calls with NG trying to resolve. I was highly disappointed in that they did not have a solution other than trying to convince me that the drop in download speed was what I should experience with WiFi. When I told them that the drop happened after the firmware update, they wanted proof so I sent them a screen shot from the Orbi app. That was not good enough as they tried to tell me that app was bad. I told them Speedtest gave me the same pattern and of course they wanted proof of that which I could not provide, as to my knowledge, Speedtest does not accumulate history. They tried to place the issue on Xfinity which when I test off of an Ethernet cable, I run the download speed that I am supposed to run at + 900 Mbs not the 600 Mbs that is post firmware update. Just to be sure, I talked to Xfinity and they confirmed that they were performing as advertised. After shooting down all of their excuses, they came up with "let's throw parts at it" since they don't seem to want to own this issue. They are now shipping me a new Orbi at their suggestion though before agreeing to the approach, they told me that this would not fix the problem. I figured I have nothing to lose and the Orbi is to arrive tomorrow perhaps using this as proof that they have the issue in their firmware change. Then, I have to go through the hassle of having to return one of the Orbis. I understand that IT issues can happen and I am willing to work with anyone as long as they show interest in resolving matters. NG has not displayed that desire yet and I am highly disappointed. I have received better suggestions from the Community than from NG.
FYI, the problems of speed testing and results are effected on the CBRs internal speed test app and Orbi app. NG is aware of this and is working on it. More direct connections with wired speed tests and test apps like Ooklas installable speed test app should see to spec speeds. "It DOES NOT impact actual speeds on phones/laptops, etc. Only impacts internal Speedtest client." Fixes should be out in next FW update. Fixing problems can take longer than expected and more than just over night fix can't be done. So please be patient.
Weird update status for my family room? Downgrade? Whats going on? Also, my wifi has been down everyday and TDS says its not them again. I tried reinstalling the latest firmware... lets see if that helps.
be sure to power OFF the CBR and RBS for 1 minute or more then back ON.

I left it powerless for 3 to 5 minutes. After 10 min the WiFi went out again.... I'm about to dump this system and get another brand.
New FW is out:

Please help.New Firmware is not helping either. What are the options? Netgear knows this is a problem with many users and why they are not proactive in fixing this. I believe they want people to pay for support. Terrible company values. Was anyone able to recover from this disastrous firmware update without getting help from gearhead? I think we should do a class action lawsuit.
Others have already reported most current FW is better than prior version.
