ubuntu16.04 cannot connect for a period of time without a WiFi link

ubuntu16.04 can not connect the WiFi link for a period of time and can not be connected, from the online search confirmation of this one bug.

Workaround:

1.Get details of your PCI wireless card by runningsudo lshw -class network

The following information is displayed:

*-network                      description: Wireless interface       RTL8723BE PCIe Wireless Network Adapter       vendor: Realtek Semiconductor Co., Ltd.       physical id: 0       bus info: [email protected]:02:00.0       logical name: wlp2s0       version: 00       serial: b0:c0:90:5c:1c:d5       width: 64 bits       clock: 33MHz       capabilities: pm msi pciexpress bus_master cap_list ethernet physical wireless       configuration: broadcast=yes driver=rtl8723be driverversion=4.4.0-21-generic firmware=N/A ip=192.168.0.8 latency=0 link=yes multicast=yes wireless=IEEE 802.11bgn       resources: irq:16 ioport:d000(size=256) memory:df200000-df203fff

2.Get your card model info according to the product line. For instance, as can see in the question description it says so the product: RTL8723BE PCIe Wireless Network Adapter model of my card isRTL8723BE

3.Open or Create and /etc/pm/config.d/config add SUSPEND_MODULES="rtl8723be" (replace RTL8723BE with your own model number) then run and echo "options rtl8723be fwlps=N" | sudo tee /etc/modprobe.d/rtl8723be.conf reboot.

Command behavior:

sudo vim/etc/pm/config.d/config

Then enter: suspend_modules= "Rtl8723be" (note rtl8723be to replace with your own number)

Then save and exit the file

In the terminal, enter:echo "options rtl8723be fwlps=N" | sudo tee /etc/modprobe.d/rtl8723be.conf

Then enter reboot to restart
