R7800 - DL speed 1/3 that of UL Speed over WiFi
Hello! I've recently upgraded to gigabit fiber in my home and as a result, have upgraded my network hardware. I have an Ubiquiti Edgerouter Lite feeding a brand new R7800 in AP mode. Connected via et...

Thanks for that suggestion. Might be worth a shot.
After trying the Synology and Unifi AC HD and getting essentially identical performance from all three, I'm thinking this could be some sort of limitation of my computer. As a result, both the Synology and Unifi were sent back and I'll plan to keep the R7800 for the forseeable future. So trying out 3rd party FW seems like a logical next step to try when I have time.

Hi netwrks. Thanks for the help. I tried basically everything you mentioned with exactly the same results each time.
- HT 160 is already disabled
- Disabled MU-MIMO with no effect
- Tried iPerf3 with one gigabit computer connected via eithernet and the other new MacBook Pro via 5Ghz wifi and it gave me the same results again when the wired machine was the server. When swapped them and the wifi machine was the server, again same results, it was much faster.
- Also tried setting it in router mode. No difference.
I'm stumped. I may check out the Unifi if I can't figure this one out or the Synology gives me the same thing. I'd love to get the R7800 to work, but it seems to be some sort of hardware or software limitation.

Have tried disabling the traffic monitor.
Someone reported for his x6 he had similar issues with both wired and wireless reporting 450/450mbps. Once he disable the monitor it jumped back to 930+mbps

Disabling traffic monitor, if it can be enabled in AP mode, is a good idea..
EDIT: the wired testing you did, was that directly connected to the ERL, or on the back of the 7800? If you tested wired, connected to the ERL, for giggles, swap out your Ethernet cable between the ERL and 7800.

The traffic meter is grayed out in AP mode, so it must be disabled by default, since I can't even select it. Also, the wired testing I did with iPerf was when the wired computer was connected to the back of the R7800.
Still stumped... but that also makes me curious if a similar AP with similar (or nearly identical) hardware would perform any better. Hope to find that out soon.

Do you have any other devices apart from MAC.
It always clients culprit can be . As this is raw performance. Wireless speed of 800+ itself a big deal.
Does your mac have 3x3 client in AC band. what is the connection rate you see. Are you testing in speed test or doing a heavy ftp download test to confirm this.
