Fails to associate with AP after resume
First noticed this problem after kernel update 4.13.10 -> 4.13.11, also reproduced on 4.13.12. After resuming networkmanager shows available networks, but can't connect to any. No wifi problems before suspend.

Log for kernel 4.13.10 shows same error messages, but no problems with wifi connection after resume.
As you are the one with the problem, you need to bisect between 4.13.11 and 4.13.10 to find the bad commit.
Took a quick look over changelog before starting bisect, there is only one commit related to wireless or usb: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git/commit/?id=f2aa694b7459f20d37199651bc2a4495a5559502
Maybe this will give you some clue
Same regression between stock Ubuntu kernels 4.13.0-17-generic and 4.13.0-18-generic, changelog shows, that later one is based on 4.13.13 mainline kernel.
I have the same answer as the one I stated above: You need to bisect the problem between those two Ubuntu kernels. I cannot do that as your machine is the one with the problem.
Unfortunately I'm unable to build kernels right now -- I don't have enough space.
I can confirm the same behavior on 4.14.0, the good news is that doing
# rmmod 8723bu
# modprobe rtl8723bu
After waking up makes it go again.
Then investigate adding the appropriate scripts to unload on going to sleep and reloading on waking up.
Yes, I should have said that I also did that, but adding systemd sleep hooks worked perfectly, and wifi is now fully functional.

i have this same problem on my Alpha litebook running Manjaro.
Could you please explain what you did to solve this problem?
Thannks !!
Here's what I did. I found some examples on the Arch wiki. i created 3 files; wifi-sleep.service, wifi-wake.service and wifi-resume.service. I placed the files in /etc/systemd directory and then enabled the 3 services.
So far, everthing seems to be working.

cfg80211: fix connect/disconnect edge cases
commit 51e13359cd5ea34acc62c90627603352956380af upstream.
If we try to connect while already connected/connecting, but
this fails, we set ssid_len=0 but leave current_bss hanging,
leading to errors.
Check all of this better, first of all ensuring that we can't
try to connect to a different SSID while connected/ing; ensure
that prev_bssid is set for re-association attempts even in the
case of the driver supporting the connect() method, and don't
reset ssid_len in the failure cases.
While at it, also reset ssid_len while disconnecting unless we
were connected and expect a disconnected event, and warn on a
successful connection without ssid_len being set.

Some info about this (just a braindump).
The problem seems to be originated in https://github.com/torvalds/linux/blob/51e13359cd5ea34acc62c90627603352956380af/net/wireless/sme.c#L1077 since prev_bssid is not being set by https://github.com/torvalds/linux/blob/51e13359cd5ea34acc62c90627603352956380af/net/wireless/nl80211.c#L8942
So is info->attrs[NL80211_ATTR_PREV_BSSID] supposed to be set by the driver during suspend?
@karora no, that's set by the userspace when using nl80211 on reconnection. I checked wpa_supplicant and it appears that it should set it correctly (see https://w1.fi/cgit/hostap/plain/wpa_supplicant/ChangeLog). I'm still looking into it.
Still somehow this is mismanaged by the driver causing this problem.
Just to update this on resume NL80211_ATTR_PREV_BSSID is not set by wpa_supplicant. This is only triggering the problem but probably it's correct and not a problem in itself.
I installed the updated driver on my Alpha Litebook running kernel 4.15. All is well so far.
Thanks !!!
It works on my system, thus there is a problem with your user-space components that control network connections.
Do some research on how to set up a script that will unload the driver on hibernate or suspend, and reload it on resume.
After some debugging of wpa_supplicant, found that it's error is "nl80211: MLME connect failed: ret=-114(Operation already in progress)", returned, as i can see, directly from driver, but can't find where
This code is returned from kernel/net/wireless/sme.c, line 1200 "If connected, reject (re-)association unless prev_bssid matches the current BSSID."
