Problem with adapter TP-Link wn722n chipset(Atheros AR9271)

er flag

I cannot use adapter TP-Link wn722n on lubuntu 20.04 on laptop. I tried to install drivers for github but nothing works. Kernel version is 5.15.0-56. Please can you give me more information and suggestions what can i try to do, to fix this problem. Meanwhile i also cannot use wifi which is integrated on my laptop. Activation is on F12 button. When i activate it's still writes, wifi disabled. Also when i type sudo rfkill list, it shows that it's hard blocked. Also to mention,all these things (integrated wifi and adapter TP-link) works normally on windows OS. Thanks in advance.

Also this adapter is in list bellow: [1]: https://i.stack.imgur.com/dqZby.jpg

Please edit your question to show the exact result of the terminal command: `rfkill list all` and: `sudo dmesg | grep ath9`

@chill555, do you maybe know, if there is some references or link for downloading drivers for TP-Link WN722n for kernel 5.15.0-56?

No. The required driver has been included in the kernel for many years. A newer or older or different driver isn't going to fix the hp_wmi and rfkill problem.

Ahaa, so there is not so much what i can do to fix this problem, instead of hp_wmi and rfkill? Is this problem related to HP, or?

All you can do it remove the card and tape off pin 20. It is an hp-wmi (HP) problem entirely. I regret that I have no better suggestion.

And about tp link adapter?

If the helper module hp_wmi reports that the airplane mode switch F12 is set to disable wireless, then *all* wireless is disabled.

hi @chili555, sry for not answering on the time, i can tell you that problem is solved thankfully to you. I remove the internal wifi card from my HP laptop, and after that I pluged in TP-Link adapter and wifi list are shown. I also tried to plug in Netis Wifi adapter and wifi list are also shown. So thank you for that advice. Best Regards chill555.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
