Hi,

Does these iphones have same problem when connect to other APs or routers?
What's the firmware version of EAP225? What's the models and OS of iphone?

Yeah, I've been having issues with maintaining speed on my EAP245 and with iPhone 6 Plus and iPhone 7 Plus.

 

I recently reset everything, and at first I got good speeds....~350Mbps down/~400Mbps up. (I can get wired speeds of around 940Mbps down and up...maybe a hair higher on the up, but once I resume cloud backups, I'm sure that'll change.)

 

But, it'll feel like its slowing down during the day, and when I wake in the morning, can't connect to anything or it'll feel like I'm doing dialup again...actually worse.

 

Though download is more impacted than upload.  I had a test result of 0.09Mbps down / 81.5Mbps up.  A couple later cases of 21.3 / 361 or 69.1 / 324.... hmmm, I actually have a 0.00 / 37.1 result.

 

Got so frustrated, that I dug out my Airport Extreme.... 440 Mbps down / 513 Mbps up.  Problem is that I have 3 vlans (4 if you count management vlan so that I can use Omada app on my iPhone.)

 

Got the latest firmware on it...hmmm, there's a V3 version now?  (wonder what happened to V2)

 

Hmm, the V3 sounds like a big step up....it has 2 gigabit ports, MuMimo, band steering, airtime fairness....  Also it draws 12.3W (vs, IIRC, 12.5W), so its a 802.3af POE rather than 802.3at POE of the V1. (and it comes with a passive POE injector....rather than the wall wart, which was a few inches short...so I had to get an injector.)

 

If I can get this speed problem resolved, I'd probably just live with it (versus wishing I got the V3).  Since, I did get it cheap on Amazon Prime Day.

I have exactly the same issue. When connecting with my iPhone 7 or iPhone 11 I experience extreme loss of speed. After the first setup the speed was well, both on 2,4 and 5Ghz. But minutes after it, the speed drops dramatically. Did a complete reset of my EAP225 AP's and Omada cloud controller. In the beginning the speed seems good, but again the speed drops after some time. Also did a reset of my iPhone network settings to factory default. That works for a couple of minutes after which the speed drops again. Unable to pinpoint what the exact issue is. Didn't experience any of this with previous routers. I reall hope TP-Link can solve this issue, it is really bothering.

Still after updating all 3 AP's I have the same issue, my iPhone (XR) loses internet connection, the Wifi connection stays fine.

There's no problem with my laptop and iPad
