This is interesting, an H2C command was dropped, but no idea which. [ 9.848052] rtl8723be: error H2C cmd because of Fw download fail!!! Disconnection happened at boot+440 seconds, associate+429 seconds; [ 439.871033] rtlwifi: AP off, try to reconnect now [ 439.871093] wlp2s0: Connection to AP 4c:5e:0c:c7:fa:e3 lost I cannot tell what causes disconnect. I wonder if the same timing of the problem happens always, or if the timing varies. Init MAC failed was another 30 seconds later; [ 468.600670] IPv6: ADDRCONF(NETDEV_UP): wlp2s0: link is not ready [ 469.618926] rtl8723be: Init MAC failed Looking at _rtl8723be_init_mac, there are two false returns; hardware power on fail, and llt write fail. Sorry, I don't have rtl8723be hardware. R?kosi, did any older kernel keep connection? -- James Cameron http://quozl.netrek.org/
