I have the same issue and have been for about 6 months. Everything works fine and then a device can see the main Wifi but no internet connection. Switch to guest Wifi and it works fine, try and switch back to main Wifi and still not connection. If I reset router it will all work for a week or so and then it starts again. If I leave devices on guest Wifi they do not have any issues.
My house is small, so I do not have a satellite running just my main router, Wifi strength is great on all devices. Firmware is V4.6.8.2
I am not a router expert, could someone please share steps to "Set orbi router to AP mode" or will that not help in my case because I am not running any satellites?
Thanks for any help, love the Orbi until this issue started happening.... Would love for it to work flawless like it originally did.
What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too?
Has a factory reset and setup from scratch been performed since last FW update?
What is the size of your home? Sq Ft?
What channels are you using? Auto? Try Auto and 48 on 5Ghz. Or 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?
You might update FW to v.5 as well and see if anything changes:
