None of the known fix (disable pm for wireless, change kernel module options, disable bluetooth, get last wifi_new driver) has work so far. Wifi works out of the box, then stop with no message. disconnect-connect again and it works perfectly for 5 more min! here are some significant dmesg warning [ 1.833114] r8169 Gigabit Ethernet driver 2.3LK-NAPI loaded [ 1.833134] r8169 0000:04:00.0: can't disable ASPM; OS doesn't have ASPM control [ 1.990773] usb 1-3: new high-speed USB device number 2 using xhci_hcd [ 2.119481] usb 1-3: New USB device found, idVendor=1a40, idProduct=0101 [ 2.119488] usb 1-3: New USB device strings: Mfr=0, Product=1, SerialNumber=0 [ 2.119492] usb 1-3: Product: USB 2.0 Hub [ 2.120597] hub 1-3:1.0: USB hub found [ 2.120630] hub 1-3:1.0: 4 ports detected [ 2.120940] usb: failed to peer 1-3-port2 and usb2-port1 by location (1-3-port2:none) (usb2-port1:usb1-port1) [ 2.120944] usb 1-3-port2: failed to peer to usb2-port1 (-16) [ 2.120946] usb: port power management may be unreliable after suspend/resume, I have a lot of those : [ 2650.032170] i915 0000:00:02.0: BAR 6: [??? 0x00000000 flags 0x2] has bogus alignment and [ 2650.032294] pcieport 0000:00:1c.0: BAR 14: no space for [mem size 0x00200000] [ 2650.032312] pcieport 0000:00:1c.0: BAR 14: failed to assign [mem size 0x00200000] [ 2650.032353] pcieport 0000:00:1c.0: BAR 15: no space for [mem size 0x00200000 64bit pref] and [ 2653.779718] xhci_hcd 0000:00:14.0: xHCI xhci_drop_endpoint called with disabled ep ffff880076bba490 lspci gives : 02:00.0 Network controller: Realtek Semiconductor Co., Ltd.
