I see the same bug on my Lenovo G50-45. Unloading and reloading the module as in #56 gets me back online. However, its not a permanent solution as it will again drop intermittently.
Kernel info: 3.16.0-34-generic #45~14.04.1-Ubuntu SMP According to http://askubuntu.com/questions/526214/how-to-set- parameters-for-realtek-wifi-rtl8723 the culprit could be powersave. Looking at the module parameters, it seems msi is 0 by default. modinfo rtl8723be filename: /lib/modules/3.16.0-34-generic/kernel/drivers/net/wireless/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: C94095C986767A931B924EF alias: pci:v000010ECd0000B723sv*sd*bc*sc*i* depends: rtlwifi,rtl8723-common,rtl_pci,btcoexist,mac80211 intree: Y vermagic: 3.16.0-34-generic SMP mod_unload modversions signer: Magrathea: Glacier signing key sig_key: 4A:55:71:9E:5C:6C:61:54:BE:06:25:D0:48:83:AE:41:1B:76:41:AD sig_hashalgo: sha512 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) How can I help (by testing) to get this fixed? Is there a way for me to look at logs or some module/device state to see if msi or power save triggered the problem? -- 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/1320070 Title: Realtek Wifi card RTL8723BE drops connection with MSI enabled Status in linux package in Ubuntu: Fix Released Status in linux source package in Trusty: Fix Released Status in linux source package in Utopic: Fix Released Bug description: As my testing result with ThinkPad E540 and other users' report[1], RTL8723BE drops connection with MSI enabled, need to backport 329d6e299f92a591acb3a80f6d597a5f9dce7e6d "rtlwifi: rtl8723be: disable MSI interrupts mode" [1] https://bugs.launchpad.net/bugs/1240940 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1320070/+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
