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?

 

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.

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?

Orbi Firmware is v4.6.3.7

 

Modem is owned by me to save on ISP fees, ARRIS Surboard SB6183.  Bought in 2019

 

Roughly 2000 sqft home, main router is on second floor, both satellites down stairs about 40ft apart, one in room below main router and other across the house.  Main reason I replaced my previous netgear nighthawk X4 was for mesh coverage of farthest room and backyard which seems to get great coverage now.

 

Should be set on auto but will check and play with setting as suggested and see what happens.

 

Neighbors have wifi, maybe three systems I can see on my phone nearby but weak signals.

 

Actually just had another issue with internet dropping, was able to disconnect router and plug modem directly into a PC.  No internet from modem either so router shouldn't be the issue.  Did a hard restart on modem which didn't fix problem immediately but internet came back up soon after.  Still haven't switched the cable back to router but looks like its not the issue.

    Is the 40 feet appart between the RBS or between the RBR and RBS? 

     

    For the modem:

    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 them back ON.

      Long story short, had two techs from ISP come out and tell me they see no issue with line into house, of course I don't have the problem when they come out as well, and a thrid buy to check the lines along the street.  I have RG6 into the house and RG59 in the walls but was told its a high quality RG59 based on the material of the shielding, only running a 200mbps service so shouldn't be an issue.  Replaced the modem with an ISP modem and still had issues.  Was having this problem when using both my older Nighthawk X4 router and Orbi router which was leading me to believe it was the line in or I got a second bad modem.  Did factory reset to the modem and both routers as I switched back and forth testing things, checked for firmware updates and was hoping to find one for the Orbi satellies as someone else had this as a solution to a similar problem here on the forum but everything is up to date.   I've tried pluggin the modem directly into my PC and haven't notice a loss of internet recently but occasional slow downs, would this cuase the router to have issues?  Played with the Wifi settings last night, put 2.4G on 6 instead of Auto and 5G on 40 instead of 48, this caused almost instant issues.  Changed 2.4G to 1 and 5G to 44, have not had internet drop issues since but we are less than 24hours out.  I'll give it some time before confirming this as a solution as when I replaced my modem for the ISP modem everything ran for 4 days without issue then it started again.

       

      On a side note, can you explain the reasoning behind changing the 2.4G and 5G channels and how this might affect the routers internet connection?

       

      Also, my Samsung smart TV won't connect to my Orbi anymore since I've been switching back and forth with two routers trying to determine wha the issue was.
