RBK752 - AX4200 Internet connection dropping


RBK752 - AX4200 Internet connection dropping

Hi There,

I purchased this device 2days ago and have had constant issues since purchase. I phoned NG support yesterday and spoke to an 'orbi specialist' whom changed a few things will list below my current set up as per NG Support advisal.

The support advisor also explained that it maybe a hardware issue if the internet continues to drop - which seems like a cop out as opposed to NG actually knowing what the constant issue with there hardware is.


I previously had ORBI Rbr20 and it worked perfectly fine, the upgrade is due to the lack of coverage rbr20 offerred and not being able to purchase the satellites in NZ anymore.


To install the RBK752 i had to factory reset the hardware itself along with the satellite.

Since establishing connection it fails to stay connected for longer than 24hrs.


Current orbi settings are as follows:

2.4ghz -6

5ghz - 44

DNS Server - Google -


And I have just updated the CTS to 2347


I have a Huawei Modem.

model: HG630b
