Orbi WiFi speed slow
Please help... I have the orbi rbk50 set up and was fine. However recently I have noticed the speed is slow. When I test in the orbi app it thinks it is 50mb but when I test on mobile I am getting abo...

You can try the following:
- Test another 5 GHz channel
- Do you have old devices connected to the network to use Long Preamble Mode which will lower the max speed for other devices if you Have Auto Mode (difference should not be that big as you see though). Try to set the Preamble Mode to Short and see if this will improve.
- As a last resort, try "calibrating" the CTS/RTS Threshold. Test with values like 2341/2345 for the 2.4GHz/5GHz.

I had a similar issue today playing with settings. I'm on a gig connection and could get no better than about 21meg or up on any wireless device. While toying with wifi power, channels and other settings I had turned OFF the WMM (wi-fi multimedia settings) under Advanced, Wireless Settings for both 2.4 and 5ghz channels. Not sure why but once I turned this off my wi-fi bandwidth just wouldn't go past about 20meg. Turned WMM back on and am getting about 400 meg on my cell phone now.
Check you WMM status also and switch it to see if it changes anything.

WMM should be enabled most of the time.

- danall22Oct 07, 2018AspirantOk...an update... So I plugged the ethernet cable into my routerand solid upload but then I plugged it into the main orbi which is connected to my router and it have the same poor download speed which must mean it is the router that is at fault here then? Maybe a new router would fix it or replace with modem and have orbi be the router?

If you have a router infront of the Orbi, this would be a problem...
Modem Combo Units:
Couple of options,
1. Configure the modem for transparent bridge 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 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.

- cahiattOct 07, 2018TutorAnd just discovered why. On the surface you would think WMM is just a QOS thing for voice and video. Not a lot of warnings about disabling it pretty much also kills AC and N protocols making your WiFi basically as slow as generic 2.4g. This is probably one feature that could use a better description or even a name change in the menu.
