Dear Debians, I have purchased Lenovo laptop around 6 months back. (Lenovo ideapad) I had installed ubuntu earlier and Wifi used to work fine. Somehow it got crashed a month back.
I have decided to switch over to debian 9.9 and installed it. Internet via Ethernet port is working. But wifi is not working and not showing available wireless networks. I searched/googled certain topic related to Debian wifi and tried installing firmware-atheros earlier. It did not work. When i tried restart, shutdown is stuck. If i force shutdown and restart, It will be stuck again. When i tried to do recover mode, msg displays that "ath10k_pci ** failed recieve control reponse completion, polling ...." Please let me know how to proceed. Thanks Senthil
