Hello, I hope this is the right place to report. I can connect via WiFi to my LTE router with the legacy 'wext' driver but not with 'nl80211'. The router is a rebranded version of this one: https://forum.openwrt.org/t/alcatel-tlc-hh40-lte-router-based-on-openwrt/77580 This command fails: # wpa_supplicant -c wpa-home-lte.conf -i wlan0 wlan0: SME: Trying to authenticate with dc:9b:d6:de:d4:27 (SSID='<redacted>' freq=2452 MHz) wlan0: Trying to associate with dc:9b:d6:de:d4:27 (SSID='<redacted>' freq=2452 MHz) wlan0: SME: Trying to authenticate with dc:9b:d6:de:d4:27 (SSID='<redacted>' freq=2452 MHz) wlan0: Trying to associate with dc:9b:d6:de:d4:27 (SSID='<redacted>' freq=2452 MHz) wlan0: SME: Trying to authenticate with dc:9b:d6:de:d4:27 (SSID='<redacted>' freq=2452 MHz) wlan0: Trying to associate with dc:9b:d6:de:d4:27 (SSID='<redacted>' freq=2452 MHz) wlan0: SME: Trying to authenticate with dc:9b:d6:de:d4:27 (SSID='<redacted>' freq=2452 MHz) wlan0: Trying to associate with dc:9b:d6:de:d4:27 (SSID='<redacted>' freq=2452 MHz) wlan0: CTRL-EVENT-SSID-TEMP-DISABLED id=0 ssid="<redacted>" auth_failures=1 duration=10 reason=CONN_FAILED while this succeeds: # wpa_supplicant -Dwext -c wpa-home-lte.conf -i wlan0 Successfully initialized wpa_supplicant ioctl[SIOCSIWENCODEEXT]: Invalid argument ioctl[SIOCSIWENCODEEXT]: Invalid argument wlan0: Trying to associate with dc:9b:d6:de:d4:27 (SSID='<redacted>' freq=2452 MHz) wlan0: Associated with dc:9b:d6:de:d4:27 wlan0: WPA: Key negotiation completed with dc:9b:d6:de:d4:27 [PTK=CCMP GTK=CCMP] wlan0: CTRL-EVENT-CONNECTED - Connection to dc:9b:d6:de:d4:27 completed [id=0 id_str=] Kernel logs, failure: Nov 30 20:24:41 papaya kernel: wlan0: authenticate with dc:9b:d6:de:d4:27 Nov 30 20:24:41 papaya kernel: wlan0: bad VHT capabilities, disabling VHT Nov 30 20:24:41 papaya kernel: wlan0: Invalid HE elem, Disable HE Nov 30 20:24:41 papaya kernel: wlan0: 80 MHz not supported, disabling VHT Nov 30 20:24:42 papaya kernel: wlan0: send auth to dc:9b:d6:de:d4:27 (try 1/3) Nov 30 20:24:42 papaya kernel: wlan0: authenticated Nov 30 20:24:42 papaya kernel: wlan0: associate with dc:9b:d6:de:d4:27 (try 1/3) Nov 30 20:24:42 papaya kernel: wlan0: associate with dc:9b:d6:de:d4:27 (try 2/3) Nov 30 20:24:42 papaya kernel: wlan0: associate with dc:9b:d6:de:d4:27 (try 3/3) Nov 30 20:24:42 papaya kernel: wlan0: association with dc:9b:d6:de:d4:27 timed out Nov 30 20:24:45 papaya kernel: wlan0: authenticate with dc:9b:d6:de:d4:27 Nov 30 20:24:45 papaya kernel: wlan0: bad VHT capabilities, disabling VHT Nov 30 20:24:45 papaya kernel: wlan0: Invalid HE elem, Disable HE Nov 30 20:24:45 papaya kernel: wlan0: 80 MHz not supported, disabling VHT Nov 30 20:24:45 papaya kernel: wlan0: send auth to dc:9b:d6:de:d4:27 (try 1/3) Nov 30 20:24:45 papaya kernel: wlan0: authenticated Nov 30 20:24:45 papaya kernel: wlan0: associate with dc:9b:d6:de:d4:27 (try 1/3) Nov 30 20:24:45 papaya kernel: wlan0: associate with dc:9b:d6:de:d4:27 (try 2/3) Nov 30 20:24:46 papaya kernel: wlan0: associate with dc:9b:d6:de:d4:27 (try 3/3) Nov 30 20:24:46 papaya kernel: wlan0: association with dc:9b:d6:de:d4:27 timed out Kernel logs, success: Nov 30 20:30:45 papaya kernel: wlan0: authenticate with dc:9b:d6:de:d4:27 Nov 30 20:30:45 papaya kernel: wlan0: bad VHT capabilities, disabling VHT Nov 30 20:30:45 papaya kernel: wlan0: Invalid HE elem, Disable HE Nov 30 20:30:45 papaya kernel: wlan0: 80 MHz not supported, disabling VHT Nov 30 20:30:45 papaya kernel: wlan0: send auth to dc:9b:d6:de:d4:27 (try 1/3) Nov 30 20:30:45 papaya kernel: wlan0: authenticated Nov 30 20:30:45 papaya kernel: wlan0: associate with dc:9b:d6:de:d4:27 (try 1/3) Nov 30 20:30:45 papaya kernel: wlan0: RX AssocResp from dc:9b:d6:de:d4:27 (capab=0x431 status=0 aid=1) Nov 30 20:30:45 papaya kernel: wlan0: associated Nov 30 20:30:45 papaya kernel: IPv6: ADDRCONF(NETDEV_CHANGE): wlan0: link becomes ready System information: Artix dist, Linux papaya 6.0.7-artix1-1 #1 SMP PREEMPT_DYNAMIC Thu, 03 Nov 2022 21:10:08 +0000 x86_64 GNU/Linux wpa_supplicant v2.10 05:00.0 Network controller: MEDIATEK Corp.
