Hello, I have the same problem on my Lenovo Flex 2-14. I tried the tip #38 and it seems to be a little more stable. But the drop outs are existent in present and the pingrate to my local router is very slow. Another problem is that i'm not able to find or connect with another bluetoothdevice with this notebook. I'm not sure if that fact is in relationship with the wifi-problem. Here are my additional parameters: uname -a: Linux Flex-2-14 3.13.0-34-generic #60-Ubuntu SMP Wed Aug 13 15:45:27 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux lspci: 00:00.0 Host bridge: Intel Corporation Haswell-ULT DRAM Controller (rev 0b) 00:02.0 VGA compatible controller: Intel Corporation Haswell-ULT Integrated Graphics Controller (rev 0b) 00:03.0 Audio device: Intel Corporation Haswell-ULT HD Audio Controller (rev 0b) 00:14.0 USB controller: Intel Corporation Lynx Point-LP USB xHCI HC (rev 04) 00:16.0 Communication controller: Intel Corporation Lynx Point-LP HECI #0 (rev 04) 00:1b.0 Audio device: Intel Corporation Lynx Point-LP HD Audio Controller (rev 04) 00:1c.0 PCI bridge: Intel Corporation Lynx Point-LP PCI Express Root Port 1 (rev e4) 00:1c.2 PCI bridge: Intel Corporation Lynx Point-LP PCI Express Root Port 3 (rev e4) 00:1c.3 PCI bridge: Intel Corporation Lynx Point-LP PCI Express Root Port 4 (rev e4) 00:1c.4 PCI bridge: Intel Corporation Lynx Point-LP PCI Express Root Port 5 (rev e4) 00:1f.0 ISA bridge: Intel Corporation Lynx Point-LP LPC Controller (rev 04) 00:1f.2 SATA controller: Intel Corporation Lynx Point-LP SATA Controller 1 [AHCI mode] (rev 04) 00:1f.3 SMBus: Intel Corporation Lynx Point-LP SMBus Controller (rev 04) 02:00.0 Network controller: Realtek Semiconductor Co., Ltd.
