I’m trying to understand a strange 6 GHz Wi-Fi behavior on the TP-Link BE550 (Indian model) and whether this is a firmware / region issue.

Some important context:

• My Xiaomi Pad 7 fully supports 6 GHz Wi-Fi
• Xiaomi never blocked 6 GHz, even before the Indian government officially de-licensed the band
• On the same router, my Pad 7 sometimes detects the 6 GHz SSID — but very randomly (once in several days or even a week)
• Most of the time, the 6 GHz network doesn’t appear at all
• No changes in router config, firmware, or environment
• I even purchased a USB Wi-Fi adapter that explicitly supports 6 GHz, and it shows the same random behavior (Adapter: https://www.amazon.in/dp/B0F48KJLGH)

This makes it clear that:

• Client hardware support is not the issue
• 6 GHz has been usable on Xiaomi devices even before de-licensing
• The inconsistency likely points to router firmware, channel selection

Questions:

1. Is there a specific 6 GHz channel / PSC channel that actually works reliably on TP-Link BE series in India?
2. Is this a known firmware issue on BE550 Indian models? But the firmware version is same as in US.
3. Has anyone received or heard about a firmware update to properly stabilize 6 GHz now that India has allowed it?

Would really appreciate input from anyone using BE550 / BE series routers in India or who understands how TP-Link is handling 6 GHz region configs.

Note: Please don’t reply saying “6 GHz Wi-Fi was blocked in India”. I’ve already clarified that the TP-Link BE550 has always been broadcasting 6 GHz signals, and Xiaomi never blocked 6 GHz on my Xiaomi Pad 7. I was receiving and connecting to 6 GHz Wi-Fi even before the government officially de-licensed it last week.

The issue here is random / unstable availability, not regulatory blocking.
