aX20 recently updated firmware and ever scince, no device connects to 5Ghz network.
All devices connect to 2.4Ghz.
If I turn off 2.4Ghz, no device can connect to the router even with 5Ghz on.
This applies to all devices including those compatible with wifi 6.
Completedf a factory reset, and same issue. New firmware appears to have disabled 5Ghz network on device

Have you checked on which wireless channel the 5GHz band is emitting its signal ?
Check that and if the wireless channel is greater than 48 try to set it to 36 and test again.
By the way you should be able to revert back to the previous FW version if that's not the case.

@terziyski Hi, its set to 7 fro 2.4Ghz and 36 for 5Ghz. Still no connection.
Will then have to reverse the auto update on the firmware.

Turniing auto-update off is a good idea.
Is your AX20 with the HW v2 ? You should see that on the bottom sticker of the device.
If it is then revert back to the previous FW release (manual upgrade with the older FW file) - check out this thread.
You should report this to support.forum@tp-link.com so the TP-Link support be aware of this issue.

Hello @Hogrod, as replied in another thread, I've forwarded your case to the TP-Link support engineers who will contact you with your registered email address later.
Please reply to the email for follow-up. Thank you.

This is the reply I got from support
"We have confirmed this problem.It seems it only exists in AX20(EU) 2.0. Other models are not affected. The new official firmware will be ready in next 2 weeks due to our Chinese spring festival. During this time, I suggest you use the beta firmware in our community. :-)"

They are joking right?
Tplink released a broken firmware without testing this week, and telling paying customers to wait 2 weeks because of it. How's that fair?
Let's hope no more routers are updated with this broken firmware, or will they tell everyone to use a beta version. Terrible .

@Hogrod I got the same email from TP-link. Good that they have responded quickly and acknowledged an issues, pretty terrible that its' going to take two weeks to release a fix. Fortunately we can roll-back to earlier version, however some customers may not be so confident to follow the procedure.
In my line of work if I released a product that had such a serious defect that slipped through testing my customer would claim financial compensation and I woud be discplined by Management.
Now I am not for a moment suggesting that any of this should happen, however it is a bit poor and certainly shows that the testing procedure in TP-link are quite lacking.
This is all particulalry amusing as on the TP-link (UK) websie they say "Founded in 1996, TP-Link is a global provider of reliable networking devices and accessories, involved in all aspects of everyday life." .... reliable, really!

Hello, I fully understand this could be frustrating to find a new firmware version causing an issue, I agree with you that the testing procedure should be more rigorous to avoid causing new bugs or issues, but I would also want to say that there are rare cases that the testing procedure may not cover every aspect as the network environment could also be a factor to bring new issues. Since I'm not on the development team, I will not know more about why this happens.
As klamath404 also mentioned, the good point is you can still revert to the previous official version to get the 5GHz back working. The new official version could be available soon, please pay close attention to your router web GUI or the Tether app for any updates.

Thanks,
fyi, You've asked me to keep a close eye on new firmware via the router UI, yet it's still being offered the faulty firmware via the tether app and router ui.
Has the bad firmware not been pulled from being offered to routers automatically?

Installing a new beta version from Support has resolved the 5Ghz connectivity issues. Thank you.
