drivers - IRQ from Realtek WiFi are loading CPU - Ask Ubuntu


i have problem toshiba satellite c850-d3k laptop ubuntu 16.04 installed , rtl8723ae wireless adapter. thing cpu consumption may go after while (30 mins - 2 hours) no reason. see image below:

$ cat /proc/interrupts             cpu0       cpu1          0:         43          0   io-apic   2-edge      timer   1:       8809        535   io-apic   1-edge      i8042   8:          1          0   io-apic   8-edge      rtc0   9:         50         81   io-apic   9-fasteoi   acpi  12:     115818      18613   io-apic  12-edge      i8042  16:        326         30   io-apic  16-fasteoi   ehci_hcd:usb1  17:      14687  151826239   io-apic  17-fasteoi   rtl_pci

i suppose problem wifi driver, because when execute

modprobe -r rtl8723ae rtl_wifi

cpu consumption goes normal (not taking account wifi not working anymore)

i've tried installing driver https://github.com/lwfinger/rtlwifi_new didn't solve problem.

the way solve problem me suspend , wake laptop each time problem appears. returns cpu consumption normal, quite annoying.

i glad if me that.
