Solved Wireless USB adapter TP-Link TL-WN823N now detected, still fails, disappears after wpa_supplicant

Hi,

I'm trying to use a Mini Wireless USB adapter TP-Link TL-WN823N on my PC. At first it didn't seem to be detected at all. After some changes to my configuration following a similar (successful) thread it is now detected (see conf files attached), and detects the two Wifis in my house correctly, but still cannot get an IP from either one :
dhclient says :
wlan0: no link .............. giving up

wpa_supplicant (-Dbsd -c wpa_supplicant.conf -i wlan0) apparently fails to authenticate and times out (see messages.txt and daemon.txt, which contain the last 500 lines of both logs)
What is interesting is it seems wpa_supplicant make the interface "disappear" (confirmed with ifconfig) :
Successfully initialized wpa_supplicant

After that, dhclient shows :
ifconfig: interface wlan0 does not exist
wlan0: not found
exiting.

I have had no luck with static IPs either (see commented lines in rc.conf)

Here is ifconfig output after booting (I have seen ALTICE_XXXX in "ssid" at some point, but I can't remember when)

I don't get what is the problem as my configuration seems correct on paper, and the dongle is detected and finds the Wifis now. Any idea would be welcome :)

I gave up trying to setup a similar device some time ago(RTL8192EU chipset). I remember that when it disappeared it wouldn't work again until reboot and even when it worked it was very slow.

Try SYNCDHCP in rc.conf and key_mgmt=WPA-PSK in wpasupplicant.conf
 
your dmesg is showing the device stalling out and falling off the bus. Is it plugged into a hub? or directly into the machine?

Thanks for all your answers, I did :
- plug the dongle in another USB port (it was on the PC directly)
- add SYNCDHCP to rc.conf
And most importantly (I think) :
- redo my wpa_supplicant.conf with wpa_passphrase
I think it is probably the last one that solved it, since I removed SYNCDHCP later and it was still working. I'll double check later if it could be the port but I have plugged a keyboard and mouse in that port and it seemed to be working.
