Model: EAP650-Outdoor  
Hardware Version: V1
Firmware Version: 1.1.3

Hi all,

 

I recently acquired said Wifi AP for our outdoor living area. After some playing around with the internal web interface and Omada controller, I reset the device and installed it for actual use.

 

However, I discovered that the wifi is very slow (< 20mibt/s up and down) on Android devices (Android 14 phone and an older tabled). With my notebook and an iPhone SE, everything was fine. There I got 600+Mbit/s). I tried various things, but nothing helped. Also on the 2.4Ghz things were much slower than expected.

 

After veryfying that the wifi channel was free and checking my phone with my internet box (1Gbit symmetrical glass fiber, router KPN Box 12, wifi 6, OFDMA, 160Mhz), I was sure something was wrong with this AP.

As a last resort, I downgraded to firmware 1.1.2. That resolved the wifi issue! So now my phone also gets around 600Mbit/s up/down. Not bad for a wifi 5 phone!

 

The phone is Xiaomi Mi8 with Lineagos 21 (Android 14) and seems fine in all other occasions. So there is something with the 1.1.2 firmware causing issues. I got simular results with an Samsung GT-T510 tabled.

 

Any idea what is going on? I reported this to TP-Link support directly as well. Hope to get also some explanation of what is happening here.

 

Many thanks in advance,

 

Bas.

I got a new phone, Google Pixel 8 and everything works like a charm. Getting iperf3 transfer rates of 900Mbit/s+ towards my wired connected notebook. So the wireless is outperforming the wired 1Gbit/s connection of the network. Time for an AP with 2.5Gbit/s Ethernet :-)

 

So I think it is safe to conclude that I happened to have old Android devices that have their issues with WiFi and WPA3 in particular.

 

Thanks for the helpfull responses. It looks like the EAP650-Outdoor is fine with 1.1.4 firmware at least and with iPhone/iPad and newer Android devices. Unfortunately, I don't have other Android devices to test with.

Thanks, that firmware wasn't available yet in my region (https://www.tp-link.com/nl/support/download/eap650-outdoor/#Firmware)

 

The firmware is much better than the 1.1.3, but still slower than 1.1.2. The upload is suffering, getting only 350-400 while the download is almost 600. I verified with a notebook and that got same results for up and down (around 450, but at much larger distance).

 

So I feel the problem is not fully solved yet. Is there already new work being done on this firmware?

With this latest firmware, are only those two devices' speeds slower than other devices in certain locations? When testing speed, get closer to the unit. Additionally, please try to optimize the network. How to optimize wireless performance of EAP products

  @Hank21 No, also on the iPhone SE I tried previously, the upload performance dropped from 650 to 540Mbit/s. With the Android phone, I did again have troubles. The up and down dropped below 20-30Mbit/s, even with the transmit and receive link speeds both at 866 Mbps according to the phone (2x2 MIMO on 5GHz, channel 36, Wifi 5.)

 

I think I revert to 1.1.2 and see if I get better stability.

  @BasMevissen 

What is the distance when you test the speed of your Android phone? When the speed reaches 20-30 mbits, which band do you connect? It appears that the speed result fluctuates. Please test the phone in the same place as the other devices. We have not received reports about sluggish Android phone speeds with this product. Also, does your network have other clients that deal a lot of traffic? 

Please use Iperf to test the speed:How to use iPerf to test the speed between the EAP and the wireless client

  @Hank21 I tried to speedtest (from Google) with WPA2 instead of WPA3. That appeared to make a huge difference. Now I get 500-600Mbit/s near the AP, which is what I expected. So for some reason, WPA3 causes issues. My home router (KPN Box 12) now also showed throughput issues with WPA3, while I hadn't them before. So I switched to WPA2 for my Android phone. Not sure what is going on here.

 

I'll organize a more recent Android phone to do more testing. For now, I'll stick to the 1.1.4 firmware and WPA2.

 

Thanks for your help so far.
