[SOLVED]cannot connect to Internet after forced shutdown

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!

Re: [SOLVED]cannot connect to Internet after forced shutdown

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   ?

Re: [SOLVED]cannot connect to Internet after forced shutdown

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:
1: lo:<LOOPBACK,UP,LOWER_UP> mtu ................
       link/loopback 00:00:00:00:00:00 brd:00:00:00:00:00:00

output of    lspci -k
02:00.0:NetWork controller : BroadCom....
             subsystem: Dell Device 0020
             Keinel modules: brcmfmac

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

Re: [SOLVED]cannot connect to Internet after forced shutdown

That all seems rational (except for the missing NIC)

Are there any mentions of Firmware for Broadcom in the output of journalctl -b   ?

Re: [SOLVED]cannot connect to Internet after forced shutdown

I was kind of hoping for something along the line of

ewaller@turing/home/ewaller % journalctl -b | grep firmware

Re: [SOLVED]cannot connect to Internet after forced shutdown

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
