Orbi Wifi 6 downloads slower (1/3rd) than uploads
I am trying to figure out why my WiFi downloads are so slow compared to my uploads when no other devices are downloading. And the router speedtest clocks at my ISPs stated speed. I have 250 Mbit up...
- Thanks for the follow-up questions!
Turns out that Ethernet speed test from MBP -> Orbi -> Fiber ONT I get 220-280 down (depending on server or when I run the test on a given server)/285 up (all servers). Similarly, when I connect via Ethernet directly into the Fiber ONT router I also get 220-280 down (depending on the server or when I run the test on a given server)/285 up. The difference between down and up seems to be the ONT or my service provider or something not related to the Orbi. Opened a ticket with them.
I tested the MBP using WiFi around the house to see if I saw the same speeds, with all other devices on or off the WiFi, and I saw the same results. Slightly slower down, 285 up.
Overall, issue does not seem to be the Orbi! Happy it’s working like it should. Thank you all for your troubleshooting suggestions and questions.
My RBR840 router and satellite RBS840 are running the latest firmware, V3.2.10.11 and V3.2.10.11 (same for both).
My ONT is DASAN Zhone Solutions, ZNID-GE-2424A1-NA. This is the link to the specs for that ONT,

I’ll try running the Speedtest.com test on my 2015 MBP and an iPhone XR (Speedtest app) later today.
Let us know. I know my MBP 2018 does.
I believe the following is the conclusion I arrived at using Speetest.com or the Speedtest OOKLA app on my MBP Mid-2015, iPad Pro, iPhone X, and Apple TV 4K (all on AC connected WiFi): regardless of device, speeds varied based on the Speedtest server I was connected to and not necessarily because of the Orbi router. Downloads were always slower, usually half of what I could get for uploads - but I think this is a function of the servers not wanting to use up their upload bandwidth (my download), but willing to use up their download bandwidth (my upload). This "server hypothesis" includes the opposite conclusion, that the servers discriminate against my ISP.
An interesting sidenote is that the iPad and MBP were the fastest on Down & Up, and the iPhone and Apple TV were slower (in that order) regardless of server. There were random occasions when the iPad achived the 250 Mbps up and down, although no other device did. It's possible the iPhone and Apple TV were consistently slower because these two devices don't provide as much power throughput for down/uploads.
Overall, it seems like speeds vary based on server chosen. I do not believe the Orbi or devices are the culprits because running the speed tests from a given device with different servers I could see sometimes 50+ (iPhone/Apple TV) or 100+ Mbps (iPad/MBP) differences on download or upload, respectively. Nothing about Orbi or the device had changed but the speeds varied significantly.
Lingering thought/question. I wonder what server the Orbi app is connecting to because I couldn't ever get the same consistent test-over-test results over that Orbi is getting on through the Orbi app (always 280+ Mbps down and up, regardless of when tested). If the sever selection isn't the issue (ie. Orbi connects to any random nearby server), could the servers be providing faster up/down to the Orbi because it detects it's a router? Doubtful, but just strange that the Orbi sees utterly consistenly up/down, but my devices see very different speeds between servers.I found I had the same results across devices with 20/40 on or off (20/40 didn't affect fast or slow results). I ran all the tests with WMM disabled and with CTS/RTS on 2347.
PS - it's possible the Orbi router gets consistently high speeds regardless of server chosen because it runs short burst-speed tests (as evidenced by the quick succession/circling of speed results shown on the Orbi app when running a speedtest, versus the Speedtest.com tests that are longer tests measuring the throughput of a longer download/upload.
Are you using a browser to speed test or Ooklas installable speed test app?
