@esaad86 I am not an expert at all but just wondering if you ensured that you are connecting to 5gHz. I am sure you have but just wondering. I have a much smaller Eap615-Wall and can consistently get 500Mbps with an iPhone next to it. Alternatively of course is to switch all the different modes in settings.

  @Hendrics yes, I have the bands separated and I'm connected to the 5ghz band

Using the HH3000, same configuration and distance away, I'm getting 650mbps-700-mbps

That is all I am ever able to get out of my 660 HD with most devices downstream (AP -> Device), mostly Androids, but even a Windows Laptops with Intel AX Adaptors.

The ONLY device I have that will break that limit is my Work iPhone, its able to hit about 600mbps somewhat regularly.

This is with different FW version, 80mhz, rural area with no interference and different channels.

While these 660HDs have good signal and can allow devices to work at great distances, the speed is just not there.

I have seen others mention this is due to the AP not transmitting using MIMO even when devices support 2x2.

On the other hand, the devices with the 300mbps +/- downstream limit can upload at about double that in the 600mbps, which seems to lend credabilit yto those reports.

  @Napsterbater yeah, my best case scenario right now in direct line of sight of the eap I get 400mbps download and 600mbps upload. Frustrating as I'm replacing the wifi on my hap ac2 which was averaging almost the same and it's only ac1200. Pretty disappointed with it tbh. Tried an Asus xt4 3 node mesh with wired backhaul and I'm getting over 700mbps download (ax1800). Thought it was something in my configuration because specs of the eap660 are much better than all these other devices I've tried

  @esaad86 Maybe try to change the Channel to 36 or 48 to see if there is any difference?

Using my house as an example

Omada Controller v5.4.6

3x EAP660HD on firmware v1.1.1 Build 20220118 Rel. 60852

-all APs connected at 2.5gb

I have 3 5ghz SSIDs being broadcast

-802.11r is enabled

-all have minimum data rate control enabled and set to 54Mbps

-Require clients to use rates at or above the specified value

I have 1 2.4ghz SSID being broadcast

-no special options enabled

Fast Roaming is enabled

AI Roaming is enabled

DTIM Period for 2.4 and 5ghz is set to 2 from the default of 1.

Airtime Fairness for 2.4 and 5ghz is enabled

2.4ghz is set to 20mhz

5ghz is set to 80mhz

Channels manually set for each AP as best as can be for 2.4 and 5ghz to limit overlapping.

I am in a typical suburban area in the midwest.  So I do see other wireless networks around me.

I get iperf3 numbers from intel ax adapters and ax phones (like one plus 8t and pixel 6) consistently over 800mbps with bursts over 1gbps to my local file/media server connected via 10gb.  This is also with 75+ wireless devices connected.  Doing internet speed tests to openspeedtest or fast.com gives me the same results (at least for download as I'm not lucky enough to have fiber in my area, stuck with over provisioned cable).  All of that with sub 80ms latency as well.

This, just to say, the EAP660HD is def capable of faster speeds than you are seeing.  If you are expecting consistently faster than 800mbps over wifi, you will need an AP that is 160mhz and clients that are the same kind of 160mhz (80+80 vs 160mhz).  You also need to realize that business APs, like the EAP660HD are built more towards density vs single client speed.  In any case, I am able to cap 80mhz channel bandwidth with 75+ devices connected across 3 APs.

  @Somnus tried but it results in lower speeds

  @esaad86 

I'm just using the software controller.  It's a free download, so I'd say it's worth a try.  You could also run the new AI Optimizer in v5.4.6 to see if that helps out at all.

In terms of DFS channels, I doubt the current hardware revision EAP660HDs will get DFS channels with firmware updates... at least not in the US.  As it would require TP-Link to recertify them with the FCC.... unless I just missed the DFS channels in their current certifications.  If they were in current certifications I'm not sure why they wouldn't have been released with them.  In anycase, would be great to see usable DFS channels though.

  @Vilmalith The controller is going to have zero effect on speed.

This has already been shoen to be an issue with the 660HDs spicificly, and potinally other APs.

Many have resported this issue via these forms and reddit, and one person was able to show its becuase the AP is not properly transmitting to many clients with MIMO so you only get half the expected realistic speed on those deivces.
