hello guys, i suspended my system and found it not react for a long time when i tried to wake it, then i forced shutdown it, i knew it was very stupid and i have regretted to it, as it could not connect to the network now.
i have spent several hours try to solve this problem but failed.
i hope someone could help me on this issue. thanks!

Wired, or wireless ?
Check the output of uname -a and of pacman -Qi linux (Assuming you are running the stock Arch kernel)
Are the version numbers of the running kernel (uname) and the installed kernel (pacman -Qi) the same? If not, the kernel won't be able to find its loadable modules.
What are the output of lspci -nn and of ip link ?

ewaller:
my computer do not have wired interface, and i am using another computer asking for help. the versions are both 4.5.4-1.
the output of lspci -nn,
...
Network controller [0280]: Broadcom Corporation BCM43602 802.11ac Wireless LAN soC [14e4:43ba] (rev 01)
...
all the output of ip link:

there seems to have "Kernel driver in use" here, but not in reality.

That all seems rational (except for the missing NIC)
Are there any mentions of Firmware for Broadcom in the output of journalctl -b ?

I was kind of hoping for something along the line of

it seems there is no problem in drive, as i just exe 'pacman -Syu' but without 'reboot'. and the there are some problem with the chip setting itself, after i start win10 in the same computer, and it also have some problems occur, and problems are solved in win10. and arch goes well after that.
thank ewaller
best wishes
