Observed behavior:

Single STA works:
- wifi0 or wifi1 alone connects successfully (auth/assoc + key negotiation completed).
Dual 2.4GHz+5GHz works:
Dual 5GHz+5GHz does not work:
- With one STA already connected, second STA fails to connect.
- Repeated scan/auth/assoc attempts on second STA, then temp disable:
  - CTRL-EVENT-SSID-TEMP-DISABLED ... reason=CONN_FAILED
- This occurs even when connecting “one at a time” (bring one up, then second).
- dmesg:

Should this firmware/driver build support stable simultaneous dual-5GHz STA connections across two PCIe functions? Are there recommented module parameters / firmware update / driver patch for this scenario?

Re: 88W9098 Dual-STA Concurrency Issue: 2.4GHz+5GHz Works, 5GHz+5GHz Fails

Hi,

If I am understanding correctly:

STA (2.4 GHz) + STA (5 GHz) works.

STA (5 GHz) + STA (5 GHz) doesn't work.

If the above is correct, I'm afraid this is expected behavior. This is because:

Radio 0 always operates in 5 GHz. Radio 1 always operates in 2.4 GHz. One Wi-Fi interface from MAC 1 operates in Radio 0 and one Wi-Fi interface from MAC 2 operates in Radio 1.

Interfaces of Wi-Fi Radio 0 (MAC 1 - 5 GHz): mlan0, uap0, and wfd0
Interfaces of Wi-Fi Radio 1 (MAC 2 - 2.4 GHz): mmlan0, muap0, and mwfd0

For more information, I would recommend you take a look at the Concurrent dual Wi-Fi (CDW) mode Release Notes section.

Regards,
Daniel.
