EAP660HD - massive tx error in both networks (32% in 2.4Ghz)
This thread has been locked for further replies. You can start a new thread to share your ideas or ask questions.
I'm using a two weeks old EAP660 HD. Omada Controller is installed on a ESXI VM.
The WIFI connection is so unstable that even streaming Spotify is not working right. Well with 30% packet loss/error. Nothing is working well.
Tx error in 2.4Ghz is 31% and in 5Ghz it's 8% which is IMHO also too high. Video chat is not working proberly.
Rx error in 2.4Ghz is 7.3% and in 5Ghz it's 1,1%
What I tried so far: Scanning channels and changing them to from 1 to 6 to 11 to 12. Nothing helps so far and I don't know what to do. It's a quite busy neighbourhood but with products from AVM or Ubiquiti this problem never happend before (had AVM before and tested U6-Pro against EAP660 - coverage of the EAP was better, but well packet loss is horrible..).
Setup looks like this:
- 1x SSID only 5Ghz, transmit power High, VLAN10, Channel Util 8%
- 1x SSID only 2,4Ghz, transmit power medium, VLAN20, Channel Util 54%
- round about 12-15 clients (9 in 2.4Ghz 3-5 in 5Ghz)
I don't know what I can do. Bandwith is quite okay but the packet loss makes important things like videos calls and simple streaming music unusable and soon the "stakeholder" (family...) will through me (and the eap 660) out of the window...

Hi @shberge
Thx for your feedback. I cannot use beta firmware, as it would allow TP-Link to get a lot of statistics and insight into my network.
Have to wait for final firmware.

Ok, I'm locked into beta now so can not roll back to test. I use PPSK and as far as I know it is only this beta version that works with PPSK ..
Yes there is time for TP-Link to push out a non beta to all access point now.

TP-Link confirmed to replace my 660HD. I will come back and report if everything is fine with the new device.

That sound's nice. I thought they found out, it's a firmware bug?? So exchanging hardware means the opposite?

Hi @Spryde
I can confirm it is just a "shown" mistake. No influence on the EAP performance.
The new firmware is in the plan but I do not have an accurate release date.

Thx for that.
It happened two times at my side, that after a big RX/TX drop/error the switch went from 1GBit/s to 100MBit/s because of a huge traffic peak several 100GB transfer showing within switch stats. So switch decided to take down speed as safety measure maybe?
But possibly it's not related to each other?

Today I can confirm again, that it's not a "shown" mistake. It can be said that the errors are related to the failures.... A lot of WPA auth failures at the same time when packets are dropping/error are coming... But only with EAP660 HD. EAP225 Outdoor, EAP610 Outdoor and EAP670 (same position as EAP660 HD - only exchanged) don't have any issues.
So why only the EAP 660 HD? And why does it take so long to solve those issues? They're there for months!

I just received the replacement part - a certified and refurbished device from TP-Link. One device is connected to the AP. Packet loss is around 45% after 20 minutes connection time. Since I'm facing too much real problems with the EAP 660 HD I'm going to sell it.
In the end I cannot tell if this is a problem in my environment (building, other networks..) but everybody who believes this is just a display problem in the controller software: Try to run the EAP 660 HD detached from the controller in single device mode. The problem still exists so it's definitely no controller related problem.
These are the results from the new EAP 660 HD TP-Link sent me (5Ghz is disabled, little inference but nearly nothing):
