I've the same problem, its a Realtek rtl8327be and I think that the problem is related with the antennas like said in this post:
http://ubuntuforums.org/showthread.php?t=2304607&page=2 It appears that there are 2 antennas and that some manufacturers (hp and lenovo) only connect one with a cable that works as a physical antenna and that the driver is trying to connect to the other one.... So people have fixed this problem changing the cable from one connector to the other.... But anyway NO, Christopher, there isn't invalid because it works in windows so its not faulty hardware. So, if it works in windows is because it isn't faulty hardware ** Changed in: linux (Ubuntu) Status: Invalid => Confirmed -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1516251 Title: 10ec:b723 [HP Notebook - 15-ac106na] Wifi unstable Status in linux package in Ubuntu: Confirmed Bug description: Networks not detected unless router is within 2feet weak signal strength, connection dropping device dropping (disappearing from NM) Have tried Rtlwifi_new drivers and kernels 3.19, 4.0, 4.26, 4.3 all have this issue ProblemType: Bug DistroRelease: Ubuntu 15.04 Package: linux-image-3.19.0-33-generic 3.19.0-33.38 ProcVersionSignature: Ubuntu 3.19.0-33.38-generic 3.19.8-ckt7 Uname: Linux 3.19.0-33-generic x86_64 ApportVersion: 2.17.2-0ubuntu1.7 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC1: al 1316 F.... pulseaudio /dev/snd/controlC0: al 1316 F.... pulseaudio CurrentDesktop: KDE Date: Sat Nov 14 14:25:40 2015 HibernationDevice: RESUME=UUID=0060deca-1eb3-44cd-81bc-67a22cea2f8c InstallationDate: Installed on 2015-11-07 (7 days ago) InstallationMedia: Kubuntu 15.04 "Vivid Vervet" - Release amd64 (20150422) MachineType: HP HP Notebook ProcFB: 0 inteldrmfb ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-3.19.0-33-generic.efi.signed root=UUID=80298215-cee2-4b22-b670-e347f14b8d0b ro quiet splash vt.handoff=7 RelatedPackageVersions: linux-restricted-modules-3.19.0-33-generic N/A linux-backports-modules-3.19.0-33-generic N/A linux-firmware 1.144+ar3012~vivid SourcePackage: linux UdevLog: Error: [Errno 2] No such file or directory: '/var/log/udev' UpgradeStatus: No upgrade log present (probably fresh install) dmi.bios.date: 07/23/2015 dmi.bios.vendor: Insyde dmi.bios.version: F.11 dmi.board.asset.tag: Type2 - Board Asset Tag dmi.board.name: 80C1 dmi.board.vendor: HP dmi.board.version: 96.31 dmi.chassis.asset.tag: Chassis Asset Tag dmi.chassis.type: 10 dmi.chassis.vendor: HP dmi.chassis.version: Chassis Version dmi.modalias: dmi:bvnInsyde:bvrF.11:bd07/23/2015:svnHP:pnHPNotebook:pvrType1ProductConfigId:rvnHP:rn80C1:rvr96.31:cvnHP:ct10:cvrChassisVersion: dmi.product.name: HP Notebook dmi.product.version: Type1ProductConfigId dmi.sys.vendor: HP To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1516251/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
