Peter Ludwig, thank you for taking the time to report this bug and trying to help make Ubuntu better. However, Linux Mint is not a software package provided by the official Ubuntu repositories. Because of this the Ubuntu project can not support or fix your particular bug. Please report this bug to the provider of the software package. Thanks!

No Model Number - nothing.But I have this problem on other HP (455) Notebooks too. OS tried: OpenSuse / Kubuntu / Linux Mint Mate (card does not work out of the box / no scanning) The Wifi card is: (in Germany!) -------------------------------------- lspci -nn | grep -iA2 net 02:00.0 Network controller [0280]: Realtek Semiconductor Co., Ltd. RTL8723BE PCIe Wireless Network Adapter [10ec:b723] -------------------------------------- I am now under kernel: 4.4.0-21-generic I installed the newest kernel because in some threads people said the card woule be available in the newest kernel. But this was not the case. I mean the card is there but does not scan nor see any wifi networks. ------------------------------------- Before I tried everything I could find to get my wifi running but I do not even see one spot. So no connection at all. I even cloned git and compiled the driver - the compiling and installation worked fine. I tried the old and the new driver. By the way the BT seems to be fine - although I have not checked cause I do not need BT. --------------------------------------------- Here is what I tried: rfkill list all; hciconfig -a 0: hci0: Bluetooth Soft blocked: no Hard blocked: no 1: phy0: Wireless LAN Soft blocked: no Hard blocked: no hci0: Type: BR/EDR Bus: USB BD Address: 2C:33:7A:3F:E4:3E ACL MTU: 820:8 SCO MTU: 255:16 UP RUNNING PSCAN RX bytes:1327 acl:0 sco:0 events:139 errors:0 TX bytes:25058 acl:0 sco:0 commands:139 errors:0 Features: 0xff 0xff 0xff 0xfe 0xdb 0xff 0x7b 0x87 Packet type: DM1 DM3 DM5 DH1 DH3 DH5 HV1 HV2 HV3 Link policy: RSWITCH HOLD SNIFF PARK Link mode: SLAVE ACCEPT Name: 'mint-0' Class: 0x740100 Service Classes: Rendering, Object Transfer, Audio, Telephony Device Class: Computer, Uncategorized HCI Version: 4.0 (0x6) Revision: 0xe2f LMP Version: 4.0 (0x6) Subversion: 0x9f73 Manufacturer: Realtek Semiconductor Corporation (93) ------------------------------------- I added the options sugested in rtl8723be.conf options rtl8723be fwlps=0 swlps=0 But this did not help either. -------------------------------------- lsmod reports: rfcomm 69632 12 rtl8723be 139264 0 btcoexist 180224 1 rtl8723be rtl_pci 40960 1 rtl8723be rtlwifi 98304 3 btcoexist,rtl_pci,rtl8723be hp_wmi 16384 0 mac80211 733184 3 rtl_pci,rtlwifi,rtl8723be sparse_keymap 16384 1 hp_wmi kvm 532480 0 irqbypass 16384 1 kvm btusb 45056 0 crct10dif_pclmul 16384 0 btrtl 16384 1 btusb btbcm 16384 1 btusb ... ------------------------------------------------------- dmesg | grep rtl reports: [ 8.982260] Bluetooth: hci0: rtl: examining hci_ver=06 hci_rev=000b lmp_ver=06 lmp_subver=8723 [ 8.982262] Bluetooth: hci0: rtl: loading rtl_bt/rtl8723b_fw.bin [ 9.064265] rtlwifi: module verification failed: signature and/or required key missing - tainting kernel [ 9.403770] Using firmware rtlwifi/rtl8723befw.bin [ 9.404023] rtlwifi: channel plan 0x20 [ 9.404027] rtlwifi: country code 11 [ 9.422483] ieee80211 phy0: Selected rate control algorithm 'rtl_rc' [ 9.423458] rtlwifi: wireless switch is on -------------------------------------------------------- modinfo rtl8723be filename: /lib/modules/4.4.0-21-generic/kernel/drivers/net/wireless/realtek/rtlwifi/rtl8723be/rtl8723be.ko firmware: rtlwifi/rtl8723befw.bin description: Realtek 8723BE 802.11n PCI wireless license: GPL author: Realtek WlanFAE <wlan...@realtek.com> author: PageHe <page...@realsil.com.cn> srcversion: 00619764255210776FAB54D alias: pci:v000010ECd0000B723sv*sd*bc*sc*i* depends: rtlwifi,rtl_pci,btcoexist,mac80211 vermagic: 4.4.0-21-generic SMP mod_unload modversions parm: swlps:bool parm: swenc:using hardware crypto (default 0 [hardware]) (bool) parm: ips:using no link power save (default 1 is open) (bool) parm: fwlps:using linked fw control power save (default 1 is open) (bool) parm: msi:Set to 1 to use MSI interrupts mode (default 0) (bool) parm: debug:Set debug level (0-5) (default 0) (int) parm: disable_watchdog:Set to 1 to disable the watchdog (default 0) (bool) parm: ant_sel:Set to 1 or 2 to force antenna number (default 0) (int) --------------------------------------------------------- sudo iwlist scan wlan0 No scan results --------------------------------------------------------- sudo iwconfig eth0 no wireless extensions. wlan0 IEEE 802.11bgn ESSID:off/any Mode:Managed Access Point: Not-Associated Tx-Power=20 dBm Retry short limit:7 RTS thr=2347 B Fragment thr:off Encryption key:off Power Management:off lo no wireless extensions. ---------------------------------------------------------- sudo ifconfig wlan0 down sudo ifconfig wlan0 up without errors. ---------------------------------------------------------- In my disappointment I tried this: From https://bugzilla.kernel.org/show_bug.cgi?id=83641#c1 "There is a new version of this driver at GitHub.
