RBK40 Download Speed Slows Down After 5 Days
I have the RBK40 Router with two RBS20 satellites connected to my home wifi. I'm using it in router mode and not AP mode..Every 5 days my Internet speed drops from around 200mbps to around 40mbps..Th...
What FW is currently loaded?
What is the Mfr and model# of the IP modem the Orbi is connected too?
What is the Mfr and model# of the ethernet switch if one is in the configuration.
What is the size of your home? Sq Ft?
What is the distance between the router and satellite(s)? 30 feet is recommended in between them to begin with depending upon building materials.
What channels are you using? Auto? Try setting manual channel 1, 6 or 11 on 2.4Ghz and any unused channel on 5Ghz.
Any Wifi Neighbors near by? If so, how many?
Try disabling the following and see:
MIMO, Daisy Chain, Fast Roaming, IPv6 and Set 20/40Mhz Coexistence to 40Mhz only. Save settings and reboot the router and satellite(s).
Are your speeds tested wireless or wired?
Was a reset performed after the FW update?

I'm using it in router mode and not AP mode..Every 5 days my Internet speed drops from around 200mbps to around 40mbps..The satellites are not affected and I still get over 200mbps on each satellite. My satellites are connected through wireless backhaul. I can reboot the the system and every thing will go back to normal for another 5 days..What could be causing this? Memory leak of some sort) I have not changed any of the default settings except for disabling the daisy chain option. I am running the latest firmware (2.1.4.16)
1.) FW version (2.1.4.16)
2.) Arris Surfboard SB6183 Modem-If I hook up directly to the modem I get my full download speed. After I saw my speed slow down on the router I hooked my computer directly to the modem to see if the problem was coming from my isp.
3.) Home Square Feet= 2107
4.) Both satellites are almost exactly 30 feet from the router. My satellites are not affected..I'm only seeing the speeds slow down on the router on the 5th day after I reboot everything. It happens on the 5th day every time..If I reboot the system the speeds go back to over 200mbps for another 5 days.
5.) My channels are set to auto. I downloaded Netspot and none of my neighbors are on the same channel as me. I have 2 houses nearby.
6.) I've already tried disabling those options but it did not affect anything.
7.) My speeds are tested wireless.I get over 200mbps wirelessly until the fifth day and then anything connected to the router will drop to about 40mbps..Anything connected to the satillites after the fifth day will continue to see speeds over 200mbps wirelessly. After I reboot the speeds on the router will go back to over 200mbps wirelessly.
8.) There has not been a firmware update since I bought the system that I'm aware of.
I'm going to try clearing the logs next time my speeds slow down again per a suggestion from another person on this thread.
"5.) My channels are set to auto. I downloaded Netspot and none of my neighbors are on the same channel as me. I have 2 houses nearby." Can't be on same channel as this will cause interferences. Lets try manual channels, 1, 6 or 11, which ever one is less used by nieghbors. Try any channel on 5Ghz.
Currently none of my neighbors are on the same channel as me..I will check again and see if anything has changed and if they are I will change the channel. Thanks for your help!!
Try a factory reset as a last resort as well and set up from scratch. Disable MIMO, Daisy Chain and Fast Roaming as well...use manual channels...Hope something makes it better for you..

Hey guys just wanted to give a quick update on my situation. Today was the six day and my speeds dropped to around 40mbps again on the router only. I went in and cleared the logs but that did not help so I guess it's back to the drawing board. As of right now the only thing that will make my speeds go back to 200mbps is rebooting the system. The weird thing is that the satellites are not affected and anything attached to them continue to see speeds over 200mbps. I'm going to set the system up to email me the logs everyday so the logs will clear out each day and will never really get full and hopefully this will help.
Has the ethernet cable been swapped out between the modem and Orbi router?
When you are testing speeds, are you wired or wireless connected with a PC and testing with a browser at speedtest.net?
