Orbi RBK753 lowering ISP speeds after 1 day router and satellites restarted
I know this question has been asked many times because I have seen it before but I can't pinpoint where the issue resides. I have ORBI RBK753 system for around 2 years, has been working fine but ...
Swap LAN cables for sure. CAT6 UTP between the ISP ONT and RBR and RBR to laptop.
Also might test with a different PC to compare results as well.
What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too?
Be sure your using a good quality LAN cable between the modem and router. CAT6A STP is recommended.
May want to downgrade FW back to v.21. RBS first, the RBR lastly.
The ISP modem model is a Huawei HG8145V5, I'm not sure how to get the ONT or how to know it, this is the first time that I see this term.
The ethernet cable that I have between the ISP modem and ORBI router RBR750 is a category 7 cable.
What I noticed is that if I connect directly to the Orbi router through ethernet, I get speeds around 90/100 mb, but If I connect via ethernet to the ISP modem, I get the 200+ mbs.
May need to ask the ISP to help you with the ONT. Seems to have a router and wifi built in. Would be best if they can bridge it or use it's DMZ for the RBR to help with this:
This would be a double NAT (two router) condition which isn't recommended. https://kb.netgear.com/30186/What-is-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.

Try option #2 first...
https://kb.netgear.com/000061277/Which-features-are-disabled-on-my-Orbi-router-when-it-is-set-to-AP-ModeHi All,
Again it happen the issue, I verified the debug section and nothing abnormal regarding the CPU and Memory usage
CPU Load: 16.01%
Memory Usage(Used/Total): 345 MB/874 MB
System Uptime: 0 days 21:36:20
Please see the speedtest captured on july 29 at 10:55 AM and one from today where the speed was reduced the half.
I already set the Orbi system as AP mode with the same result, it only works for some time and it reduces the speed after a period of time. Installing again the firmware could help with the issue?
Thanks for all the responses and help.
What speeds are seen with a ethernet connected PC and Ooklas installable speed test app installed on the PC?
