Slow Wifi on Netgear Orbi Satellite with ethernet backhaul
I have a Netgear Orbi system with a RBR50 router and 1 RBS50 Satellite. The Satelite is connected through an ethernet cable with the router, so a good and stable backhaul connection. My internet sp...
Updated the firmware manually this afternoon. My firmware was 2.5.1.8 and the Orbi router dashboard said there were no firmware updates. However, by accident I saw that version 2.5.1.16 is available which was not detected by my orbi router/satellite.
Rebooted and tested the speed settings. I get 304Mb as expected. Now wait a few days and see if the speed stays stable or lowers again after some amount of time with these new firmware.If I test the speed when I suspect an issue. I always test with 3 devices;
- a macbook pro which is connected to the satellite via wife,
- an iPhone which is connected to the satellite via wifi
- a mac mini which is connected to the satellite by ethernet.
The speed of the mac mini is always around 300Mb, also when the speed over wifi is very slow and around 45Mb. When the wifi speed is 45Mb, both my macbook and my iphone encounter these low speeds.
If the speed is low I mostly also move my iphone to the ground floor where the router is so it can connect to the router instead of the satellite and then I always get speeds around 290-300Mb, as expected. So the issue seems to only occur when a device is connected to the satellite via wifi and the satellite is powered on for 1 or more days. Not sure after how much time the speed drops down to around 15% of the original speed.
The latest firmware is loaded.
The Router is connected to a Ziggo Connectbox. Not sure what the original brand of it is.
Home size is about 2000 square feet but as I said in the original post, the satellite is connected with the router through the ethernet backhaul. not through wifi.
MiMO, Beamforming and WMM are enabled from day 1
Daisy Chain, Circle, Armor are disabled from day 1.
20/40Mhz coexstince was disabled from day 1
Fast Roaming I disabled last week, rebooted and tested again, problem still occurred.
Just disabled IPv6, set preamble to short instead of auto.
So only 2 changes made, going to reboot and test. Return later with the results.
Is this your modem?

If so, this modem has a built in router and wifi already. 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. 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
Yes, that is my modem.
I have wifi disabled on the Ziggo modem. It used to be in bridge mode several months ago, but currently it is not not i bridoge mode. And yes, a double NATbut that doesn't prevent to get 300Mb speeds at downloads when connected to the Wifi of the Router or with an ethernet cable to the satellite. Only wifi connections to the satellite give issues with a very low speed after a while.
Just rebooted after changing the 2 settings in my previous post and now I get 302Mb download speed through wifi connected on the satellite. However, I expect it (but hope not) to be slow again tomorrow...I'll test again tomorrow.
Not all isp's bridge mode functions properly.
An easy test if it slows down again?
put the Ziggo back in router mode, disabled its wireless, and place the ORbi in Access point mode. You'd loose some features of the orbi but still retain the wirless mesh coverage and ethernet port usage.
Well, I can do that. But, if my internet speed is only slow when I am connected to my satellite (not the router) via Wifi 5Ghz band and my speed is perfect when connected to my satellite through ethernet or when I am connected to my router via Wifi, how can the issue be with the ISP modem/router?
The symptoms all point to an issue with the wifi on the satellite.
