3x NWA130BE MLO

fandabrabec

I have 3x NWA130BE APs managed thru Nebula configured as follows:

• WPA3, no transition mode
• Band select and assisted roaming on, 802.11r off
• smart steering off
• V7.30(ACIL.4)
• 5ghz channels hardwired to 36, 44 and 149 with 40MHz width, 6ghz on DCS with 160MHz width

Using it with Pixel 10 Pro, Adaptive Connectivity off

When moving around, roaming often results in unstable connectivity, either switch to cell with no wifi functioning at all or going back and forth between wifi and cell every 10 seconds. When I turn off 6GHz, everything works fine. Here is a log of one situation where the cell/wifi back and forth would keep going seemingly indefinitely.

Is it a buggy firmware or can I tweak something on my end? Thanks.

Hi @fandabrabec

We need more information to check this issue.

Please help to:

1. Replicate this issue and take a screenshot of the "results in unstable connectivity" and the WiFi MAC address (the information under SSID details).
2. Please help to collect the diagnostic file of the two AP.

Thanks!
