Additional information with kaihengfeng's comment.

dmesg shows wifi stops working after suspend and resume. wifi driver also tried to restart hardware but failed:

[ 459.548998] e1000e: enp0s25 NIC Link is Down
[ 461.601935] iwlwifi 0000:03:00.0: Error sending REPLY_SCAN_ABORT_CMD: time out after 2000ms.
...
[ 461.865575] ieee80211 phy0: Hardware restart was requested
...
[ 467.757292] Hardware became unavailable during restart.

If this is the case, please try to re-initialize wifi driver by "sudo modprobe -r iwlwifi; sudo modprobe iwlwifi".
