Sorry for the long delay - when working on upstream kernel testing with 3.19.0-031900.201502091451 i386/32bit to confirm bug 1422513 I realized that the internal Broadcom chip works fine after uninstalling bcmwl-kernel-source and running with above kernel.
b43 seems to do fine in that case as lsmod indicates: Module Size Used by nfnetlink_queue 17963 0 nfnetlink_log 17665 0 nfnetlink 14324 2 nfnetlink_log,nfnetlink_queue ctr 13025 1 ccm 17562 1 dm_crypt 22836 1 snd_hda_codec_realtek 68841 1 snd_hda_codec_generic 63667 1 snd_hda_codec_realtek snd_hda_intel 29576 3 snd_hda_controller 30930 1 snd_hda_intel snd_hda_codec 121018 4 snd_hda_codec_realtek,snd_hda_codec_generic,snd_hda_intel,snd_hda_controller carl9170 86955 0 snd_hwdep 13276 1 snd_hda_codec uvcvideo 78147 0 ath 24509 1 carl9170 snd_pcm 89214 3 snd_hda_codec,snd_hda_intel,snd_hda_controller videobuf2_vmalloc 13485 1 uvcvideo videobuf2_memops 13170 1 videobuf2_vmalloc videobuf2_core 45571 1 uvcvideo arc4 12509 2 snd_seq_midi 13324 0 snd_seq_midi_event 14475 1 snd_seq_midi v4l2_common 14442 1 videobuf2_core snd_rawmidi 25786 1 snd_seq_midi videodev 140634 3 uvcvideo,v4l2_common,videobuf2_core b43 404250 0 snd_seq 56978 2 snd_seq_midi_event,snd_seq_midi bcma 47124 1 b43 coretemp 13358 0 snd_seq_device 14451 3 snd_seq,snd_rawmidi,snd_seq_midi mac80211 643092 2 b43,carl9170 snd_timer 29036 2 snd_pcm,snd_seq media 21127 2 uvcvideo,videodev joydev 17311 0 serio_raw 13251 0 snd 67102 16 snd_hda_codec_realtek,snd_hwdep,snd_timer,snd_pcm,snd_seq,snd_rawmidi,snd_hda_codec_generic,snd_hda_codec,snd_hda_intel,snd_seq_device lpc_ich 17000 0 cfg80211 462008 4 b43,ath,mac80211,carl9170 rfcomm 59314 8 btusb 31907 0 bnep 19107 2 bluetooth 444619 22 bnep,btusb,rfcomm soundcore 14635 2 snd,snd_hda_codec shpchp 32280 0 ideapad_laptop 18132 0 sparse_keymap 13658 1 ideapad_laptop mac_hid 13099 0 parport_pc 32154 0 ppdev 17423 0 lp 13359 0 parport 40945 3 lp,ppdev,parport_pc ums_realtek 18008 0 uas 22257 0 usb_storage 57197 2 uas,ums_realtek i915 956578 3 i2c_algo_bit 13316 1 i915 drm_kms_helper 106489 1 i915 tg3 159805 0 psmouse 106642 0 drm 276577 5 i915,drm_kms_helper ptp 18938 1 tg3 pps_core 18768 1 ptp pata_acpi 12901 0 ssb 56722 1 b43 video 20019 1 i915 wmi 18843 0 ** Tags added: kernel-fixed-upstream -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1385059 Title: 14e4:4315 [lenovo IdeaPad S10e] No WiFi - Broadcom Corporation BCM4312 802.11b/g LP-PHY (rev 01) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bcmwl/+bug/1385059/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
