'Can't find server' errors with ORBI 753

Understand, you may need to find one with a built in router, however some also offer a bridge mode or mode only mode as a featrue so this will work as well. 

I tried dealing with the "Can't find server" errors over the past several days, but there are a few other issues with this router. Devices seem to come and go; one minute they're shown on the device list page, and the next they're gone. Not a big deal with iPhones, iWatch, and iPads, but my Brother printer is also a casualty. The solution seems to be that when I want to print I first have to cycle power on the Brother, at which time Orbi sees it (again!) and assigns an IP address. As long as I start printing within a few minutes, all is well. If I delay, the Brother disappears and it's back to the power cycle "solution".

I finally decided to do a factory reset and start over, but even this didn't fix things - same problems with server not found errors and device dropouts. After fighting this for a few hours today I finally gave up, disconnected it, and reverted to my original router and WiFi extenders. Not nearly as good coverage as with the Orbi, but having a slower but reliable network is orders of magnitude better than a fast and unreliable one. Luckily I'm within the return period, so the Orbi goes back tomorrow and I'll continue to wait for a reliable mesh system. A real shame.

You didn't get a chance to try a different modem did you.Your modem is of a older generation and also not working at 1000Mbps which is what Orbi supports. I would stil consider your modem a culprit as well. At any rate, sorry it didnt' work out. 

Good Luck. 

Dealing with exactly the same issue with my RBR750. On with support (had to buy gearhead support) and after 4 days of reset, reset, reset, on/off reset, reset downgrade firmware, upgrade firmware, reset they agreed this morning to RMA my router. I feel as though this is a hardware issue since the older firmware did it as well but we will see

Thanks for the update. I agree thatr it's definitely a problem with the Orbi, although I'm not sure if it's hardware or software. The problem is certainly not due to a slower modem, unless there's no flow control (hardware or software) or insufficient buffering in the Orbi, which is, once again, an Orbi issue. I never got a response back from Netgear support, which is another reason I returned mine.

If Netgear does acknowledge that there's a problem and fixes it I'll see about trying it again, but if not I'll have to se if there's a mesh network system that has equivalent coverage and good reliability.

What Firmware version is currently loaded?
What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too?

It is on current, 3.2.16.6_1.4.4

at&t arris bgw210 modem.

You modem already has a built in router, This would be a double NAT (two router) condition which isn't recommended. https://kb.netgear.com/30186/What-is-Double-NAT
https://kb.netgear.com/30187/How-to-fix-issues-with-Double-NAT
Couple of options,
1. Configure the modem for transparent bridge or modem only 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.
2. If you can't bridge the modem, disable ALL wifi radios on the modem, configure the modems DMZ/ExposedHost or IP Pass-Through for the IP address the Orbi router gets from the modem. Then you can use the Orbi router in Router mode.
3. Or disable all wifi radios on the modem 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

Way ahead of you. I had an RBR50 prior and already have my AT&T set to passthrough. No double nat here

Something to try as well, set the ISP modem back to router mode and change the RBR to AP mode and see if the Can't Find Server messages still appear...

I am having the same problem with a brand new Orbi 753.  Every so often following a link will get "server not found".  Very intermittment and no pattern to it that I can see, sometimes its at a site I have never visited before, sometimes its a site I was at an hour ago.  Once happened checking email via pop (at gmail).  

This problem started a day after replacing a TP Link mesh network with the Orbi mesh network.   Negear support has not been of much help, suggested diabling WiFi 6 and going to an older firmware version, neither of which helped.

What Firmware version is currently loaded?
What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too?

Is Armor enabled?

Has a factory reset and setup from scratch been performed since last FW update? 

I fixed my issue by getting an RMA AND more importantly not enabling access control. Once I do it all but hoses the system. Disabled it works 100%

Any progress on this?
