Hi  @nikisima 

 

Thanks for the feedback.

 

 MLO is also still broken (ping timeouts/packet loss, with good signal).

>>>Did you test this with a Samsung phone?

  @Vincent-TP I can not say with 100% confidence that there is an issue with a Samsung Tablet S9 Ultra (I think it was).

 

But, I can confirm that the issue is present with multiple Google Pixel 9 devices.

Hi  @nikisima 

 

Thanks for the info. We will dig more about this. 

 

 

Just to verify:

but MLO is also still broken (ping timeouts/packet loss, with good signal).

>>>Did the internet affected?

 

The official latest EAP783 (1.1.4 Build 20251030) firmware, does not only still have the non-VLAN (default 1) to VLAN bug,

>>>With MLO enabled, did you use VLAN1?

Yes, the timeouts were to external servers. The same servers were reachable over non-MLO Wi-Fi.

If you’re referring to the ping timeouts: those occurred on VLAN1 and on a "real" VLAN.

 


If you mean the VLAN bug: if I remember correctly, the same bug occurred on both MLO and non-MLO networks. To clarify further, based on my testing, I consistently saw about 13-16 KB of data transferred back from servers connected via a Wi-Fi VLAN. After that, the connection would break (the server never received ACKs, as far as I could tell), eventually timing out.

I reviewed tcpdumps from both my firewall and the server, which confirmed that neither ever saw the packets. That left the access point as the only remaining culprit.

Hello,

 

I just created an account to report the v1.1.4 has effectively a VLAN bug.
My setup:
   SSID3 = VLAN 3, 2.4GHz

   SSID2 = VLAN 2, 5GHz

   SSID1 = no VLAN (Disabled), 6GHz

Mgnt UI: no VLAN

 

From SSID2 I can target SSID3, no problem.

From SSID1, I'm experiencing TCP drops targeting SSID2 or SSID3. Devices never received ACK so it retransmits TCP packets in loop.

And from a wired trunk network, no problem to contact SSID2 or SSID3.

 

It's a critical problem, please provide a correction soon.

 

Edit, new try:

   SSID3 = VLAN 3, 2.4GHz

   SSID2 = VLAN 2, 5GHz

   SSID1 = VLAN99, 6GHz

Mgnt UI: no VLAN

 

VLAN99, DHCP OK but no internet, no access to SSID2 & SSID3. If I switch Management UI to VLAN99, everything works.

Since 1.1.4 firmware, noticed that roaming does not work anymore. Sometimes phone sitting with -82 dBm, and not switching to closest AP, which would be like 2m away. Anyone else observing the same?

 

802.11r ON

Fast Roaming ON

Non-stick Roaming ON

AI Roaming ON

MLO OFF

6 Ghz OFF

5 Ghz ON

2.4 Ghz ON

Hi  @liviu2004 

 

Thanks for the feedback. Do you mean this only happens with this iPhone? What about other wireless clients?

Please try the following:

1. update the iPhone to the latest version;

2. Disable 802.11r

Hi  @Benoit2r 

 

Thank you for your feedback. We have already resolved this issue in the next version.

Before the next version is released, you can work around this problem by setting SSID rate limits. The SSID rate limit can be set up to 10G, so it should not affect your normal usage. Note that this setting will slightly increase the device’s CPU usage, but it will not affect the product’s functionality.

Once the next version is released, you can remove this configuration.

If you prefer not to do this, please let me know.

  @Vincent-TP Thanks for coming back to me, I tested with another Iphone, version 15, this works OK, with 802.11r enabled. No issues moving from AP to AP, one does not even notice the roaming moment. yes

 

Next test:

802.11r OFF

 

Iphone 17 Pro still does not roam, lowest signal seen -82dBm.
