Thanks for posting.
As all current Intel dual band wireless adapters, the Intel® Wireless-AC 9260 supports both 2.4GHz and 5GHz bands.
The adapter can only be connected to one network at a time, therefore it can't connect to 2.4GHz and 5GHz simultaneously.
Please let us now if there's anything else we can do for you.
Thanks for your comment, but i don't understand if AC-9260 not support concurrent,
why use diplexer before antenna? (form AC-9060 datasheet block diagram), why don not use
2.4G / 5G switch replace diplexer?
Thanks for your reply.
