Router Much Slower than ModemSome quick information:- 500mbps Internet plan- ROUTER: Orbi RBR20 with 2 satellites near each other running at 50% transmission power (quite a small house).- MODEM: Netgear CM1150v Docsis 3.1- SWITCH: 8-port gigabit TP-Link (TL-SG108).- Speed test done mainly through testmy.netMODEM — no more than 38 feet cat 5e Ethernet —&gt; ORBI ROUTER — pretty damn long cat5e cable, much longer than the one that connects the modem to the router —&gt; SWITCH.So I connected my computer to the modem directly and got around 480mbps each time. When I connect directly to the switch, which is connected to the Orbi router, I get 320mbps directly on the main router and roughly the same on the satellites (test done through PS5). Furthermore, WiFi drops me down to 120mbps.What could be the issue? Is it normal to not get the same Ethernet speed when connected to a switch connected to the main Orbi router compared to directly to the modem?Edit: I brought the Orbi router where the modem is and used a roughly 10 in shorter cat5e cable. I connected that to the Orbi router with that cable. I then connected the desktop computer with the same cable I used to connect it to the modem where I got 480mbps to the Orbi router. I got roughly 300 mbps so no change from before (actually speeds were worse lol).Looking at the Orbi configurations:- MU-MIMO = off- Fast roaming = off- Implicit beamforming = off- Guest network = off- 2.4ghz = auto- 5ghz = somewhere in the 40sI do have a smart home system with Zigbee being the main + a raspberry pi. The recent test with the computer directly linked to the Orbi router without the switch did not have the switch installed (zigbee system and such are all connected through there).

Netgear has set up a community forum specifically for the Orbi AC products. Most of the people who watch that forum are more likely to have experience with Orbi and know how to work it better than those of us who follow this router forum. Might be more likely to find someone who has a solution if the question is posted there:https://community.netgear.com/t5/Orbi/bd-p/Orbi https://community.netgear.com/t5/Orbi/Router-Ethernet-Much-Slower-than-Modem/m-p/2168684#M129085 Please use this link to the main forum product list to review and choose where to make your posts. https://community.netgear.com/t5/NETGEAR-Forum/ct-p/en-netgear Thank you.

What do you get out of the router, before the switch? And with no switch on the network? I assume that all tests are wired. (PS5 means nothing to me.) Furthermore, WiFi drops me down to 120mbps. Maybe 120 Mbps is as fast as the wifi clients can handle. That's what determines wifi speeds. It might be worth a bit of background reading.

michaelkenward No I know my test computer can handle the full 500mb because from what I wrote, I said that when I connect to the modem directly, I can get the full 500mbps. When I connected to the router directly (with and without the switch on the network) using 2 different ethernet cables for the switch to the modem and using the same patch cable that I used on the computer and the modem, I got around 300mbps which was the same on the PS5 (which is connected using ethernet to the sattlite Orbi).

It looks like your modem is also a router: https://www.netgear.com/home/wifi/modems/cm1150v/ - It has multiple ethernet ports to support multiple downstream clients at once. Can you put it into bridge mode? Otherwise if you have Double NAT then that overhead can impact your speed. Alternatively, setup your RBR50 in Access Point (AP) mode and leave the router functionality to your CM1150V.

It is not a router. Modem only. Other Ethernet ports are aggregation.
