Broadcom BCM4360 & TP-Link AC1300 Wifi Adapter (Archer T6E) - No 5GHz signal!!

I recently bought this dual-channel TP-Link AC1300 Wireless Dual Band PCI Express Wi-Fi Adapter for a desktop PC that sits two floors below my router:

The PC was originally using Windows 10 and the 5GHz signal was much stronger than the 2.4GHz one.

I then decided to replace W10 with Linux Mint 21 MATE.

The Broadcom BCM4360 was recognised by Mint and the appropriate driver installed.

So far, so good.

I then found that only the much weaker 2.4GHz signal was available.

I used the excellent Wifi Analyzer (open-source) app on my Android mobile phone and this registered nothing for the 5GHz band. In contrast the 2.4GHz showed a strong signal.

I tried connecting to a “Hidden network” and creating a new network, all to no avail.

Finally after much research, I discovered that the Broadcom BCM4360 802.11ac Wireless Network Adapter [14e4:43a0] (rev 03) does not see 5GHz networks with a high channel number.

See confirmed bug #1574196 at Launchpad:

To rectify this, it is necessary to login to the router and change the channel for the 5GHz to a lower one.

In my ASUS router I went to Advanced Settings > Wireless > Wireless General > select 5GHz band.

Then clicked on Control Channel and reduced the figure from 140 maximum to 36.

Clicked on Apply and logged out.

The Wifi Analyzer immediately picked up a very strong signal from the 5GHz.

All is now well.
