RBK50 With 2 sattelites losing internet speed

[NowayDude]

As I have mentioned above the RBK50 router with 2 satellites. I have 250Mb internet speed. When I reset the router every device in my house has 250 Mb speed, but after a day it slows down to 40-50 mb. I have already done a factory reset, etc. The satellites connection is good at 5ghz. Can anyone help me?

[NowayDude · Accepted solution]

Sorry for the delay in answering the questions. I went back to 2.3.5.30 and have now the appletv downstairs as main HomeKit Hub (the others are l stand-by). I have also updated all the apple stuff to 13.1.2. I do have a good connection for a couple of days now. I think the solution was to have the (main) HomeKit Hub connect to the router and not to a satellite. For now on I am happy and I would thank you all for your help.

What firmware are you on?

What modem is it connected to? (model number)

When the speeds slow down, is it all devices including the hardwired devices that slow down or just the wireless devices?

Are you using QoS?

What I'd start with is to try and determine if its the wireless backhaul causing the problems, the satellites talking to the device (aka bandsteering or another setting), or the device itself.

How to do this?

hardwire into the satellites with a laptop/pc and speedtest over the ethernet connection. If you're getting full speeds without slow downs, the backhaul is probably not the issue.  If you're not getting full speed while doing this, then we need to investigate your backhaul.

If the backhaul is fine then its back to do all the devices slowdown or just the wireless devices?

[NowayDude]

Thank you Plemans for your quick reply.

Both the Sattelites and the router have firmware 2.3.5.30 The Router is RBR50, 1 Sattelite is RBS50 and the other is RBS40. I have tested it wired and the RBR50 has wired a speed of 235Mb and the RBS40 250Mb. The upload speed of all the devices is 25Mb. If the downloadspeed is slower, the upload stays at 25Mb. 

The modem is in bridge and if I test the download speed with the Orbi app is always has a download speed of 250Mb.

If I test it now on my 2 Apple Iphones 8 and Macbook air 2017 I have a downloadspeed of 40 Mb and an upload of 25Mb. I am connected to the router which is 2 meters aaway.

I don't know waht you mean with

[NowayDude]

Excuse me for not typing further (has to do with the autosave). I don't know what you mean with Qos. 

[plemans]

so hardwired in to router and satellite, you're speeds are good.

Over wireless, regardless of connection to satellite or main router, they're slow. 

Is this correct?

QoS is bandwidth management. it ensures that all devices get enough bandwidth for usage.

do you have this enabled or disabled? 

Is there much wireless interference in your area? try changing the wifi channels.

Try enabling/disabling these settings to see if it helps:

Beamforming, airtime fairness, mu-mimo

[plemans]

and I know the article is for nighthawk. its more to explain what qos is. 

[NowayDude]

Hello Plemans,

Again thank you for reactions. With http://orbilogin.net/QOS_main.htm I saw that Qos is disabled. Is that alright?

I have different channels then my neighbors. I will try your other suggestions.

[NowayDude]

Hello,

BTW beam forming and fast roaming are both enabled.

[NowayDude]

The (not so!) funny part is that if I enable/disable something on my Orbi by applying , the wireless speed is 250Mb but after a couple of hours it goes back to 40Mb.

[plemans]

You didn't put what model modem it is. You've put that its in bridge mode but it wouldn't be the first time that a routing function on a combo device has caused decreased speeds. Its just interesting that its only happening over wireless.

Model number of the modem?

Did you disable wireless on the modem? (you put its in bridge mode so I imagine its a combo device)

Have you tried the old reinstall the firmware to the main orbi router and reset it back to factory? It occassionally fixes issues. 

How old is the orbi system?

[NowayDude]

Hello Plesman,

Thank you for your reply.

The modem has the brand of my provider. I will ask which model and vendor. The Orbi is 1 1/2 year old. Yesterday I have done a factory reset. Do I have to do it again by the way you mentioned?

[NowayDude]

Excuse me for replying my own message. Wireless is disabled on the modem.

[plemans]

You can try if you'd like. If the firmware was corrupt, a factory reset only erases the settings. it doesn't load a backup firmware (sadly).  If the wireless speed decrease is happening regardless of connection to satellite or router, I'd shut off the satellites while you're troubleshooting.

[NowayDude]

Hello Plesmans,

I have tried all the suggestions unfortunately without success. Is it possible that HomeKit would be the reason ? The problem is I guess 5ghz.

[plemans]

when you say the problem is the 5ghz, what do you mean and how did you come to this realization?

If you're modem has wireless and you say its in bridge mode, how about turning the bridge mode off and letting the modem function as the router. Then place the orbi in AP mode (access point) and seeing what happens. 

It wouldn't be the first time an isp supplied modem/router caused issues.

[NowayDude]

Hello Plesmans,

The devices are connected at 5ghz. BTW the vendor of the modem is Compal. Type CH7465LG-ZG.

[NowayDude]

Do you have experienced with Compal?

None, but its worth a chance to leave the compal in router mode (disable wireless on it) and just run orbi in AP mode to see how it functions. 

[NowayDude]

I will try it, although not today. I was just thinking: 1 satellite is a RBS40. Do you know any problems with the RBK50 with 1 RBS50 satellite and 1 RBS40 satellite?

[plemans]

No the RBS40 just has a more narrow backhaul but not enough to slow you down that much.

Since no one has asked or mentioned....this may be your problem ...............FW  2.3.5.30 

Do a search

[NowayDude]

Hello VAJim,

Thank you for your comment. Also with the older FW’s I had the same problems. Tomorrow I will shutdown the RBS40 and I will tell here what happened. Thank you both for helping me. 👍

[ekhalil]

@NowayDude What type of wired devices do you have connected to Orbi? Do you have any mesh speakers (e.g. Sonos) attached to Orbi?

[NowayDude]

Hello ekhalil,
I have a Synology NAS and IKEA Bridge (lamps) wired. I have 2 unwired Apple HomePods.

[NowayDude]

Strange! It’s middle in the night. Like I said I have 2 satellites and of course the router. The router is downstairs and the satellites on the first floor. I had in my bedroom (upstairs and far away from the router) 250mb connected 5ghz to the router. Now I am at another room 1 1/2 m form the router and I have also 250mb connected to the satellite upstairs.
