When connecting to the AP of my router, everything works as expected provided no other PC has already been connected to the AP. If that is not the case, I have to reboot the router and make sure my new laptop is the first to connect. Here is the log of such a failing connection: Oct 1 08:55:41 ares kernel: [ 8774.854934] ADDRCONF(NETDEV_CHANGE): wlan0: link becomes ready Oct 1 08:55:41 ares NetworkManager[1830]: (wlan0): supplicant interface state: associating -> associated Oct 1 08:55:48 ares kernel: [ 8781.880987] wlan0: deauthenticated from ce:67:c3:86:34:80 (Reason: 15) Oct 1 08:55:49 ares wpa_supplicant[1859]: CTRL-EVENT-DISCONNECTED bssid=ce:67:c3:86:34:80 reason=15 Oct 1 08:55:49 ares kernel: [ 8781.931122] cfg80211: Calling CRDA to update world regulatory domain Oct 1 08:55:49 ares NetworkManager[1830]: (wlan0): supplicant interface state: associated -> disconnected Oct 1 08:55:49 ares NetworkManager[1830]: (wlan0): supplicant interface state: disconnected -> scanning Oct 1 08:55:50 ares wpa_supplicant[1859]: Trying to authenticate with ce:67:c3:86:34:80 (SSID='Kirya' freq=2422 MHz) Oct 1 08:55:50 ares NetworkManager[1830]: (wlan0): supplicant interface state: scanning -> authenticating Oct 1 08:55:50 ares kernel: [ 8783.091580] wlan0: authenticate with ce:67:c3:86:34:80 (try 1) Oct 1 08:55:50 ares wpa_supplicant[1859]: Trying to associate with ce:67:c3:86:34:80 (SSID='Kirya' freq=2422 MHz) Oct 1 08:55:50 ares kernel: [ 8783.093674] wlan0: authenticated Oct 1 08:55:50 ares NetworkManager[1830]: (wlan0): supplicant interface state: authenticating -> associating Oct 1 08:55:50 ares kernel: [ 8783.114042] wlan0: associate with ce:67:c3:86:34:80 (try 1) Oct 1 08:55:50 ares kernel: [ 8783.123261] wlan0: RX ReassocResp from ce:67:c3:86:34:80 (capab=0x411 status=0 aid=2) Oct 1 08:55:50 ares kernel: [ 8783.123265] wlan0: associated Oct 1 08:55:50 ares wpa_supplicant[1859]: Associated with ce:67:c3:86:34:80 Oct 1 08:55:50 ares NetworkManager[1830]: (wlan0): supplicant interface state: associating -> associated Oct 1 08:55:52 ares kernel: [ 8785.016027] wlan0: no IPv6 routers present Oct 1 08:55:56 ares kernel: [ 8789.887920] wlan0: deauthenticated from ce:67:c3:86:34:80 (Reason: 15) Oct 1 08:55:56 ares wpa_supplicant[1859]: CTRL-EVENT-DISCONNECTED bssid=ce:67:c3:86:34:80 reason=15 Oct 1 08:55:56 ares kernel: [ 8789.903098] cfg80211: Calling CRDA to update world regulatory domain Oct 1 08:55:56 ares NetworkManager[1830]: (wlan0): supplicant interface state: associated -> disconnected Oct 1 08:55:57 ares NetworkManager[1830]: (wlan0): supplicant interface state: disconnected -> scanning Oct 1 08:55:58 ares wpa_supplicant[1859]: Trying to authenticate with ce:67:c3:86:34:80 (SSID='Kirya' freq=2422 MHz) Oct 1 08:55:58 ares NetworkManager[1830]: (wlan0): supplicant interface state: scanning -> authenticating Oct 1 08:55:58 ares kernel: [ 8791.063535] wlan0: authenticate with ce:67:c3:86:34:80 (try 1) Oct 1 08:55:58 ares wpa_supplicant[1859]: Trying to associate with ce:67:c3:86:34:80 (SSID='Kirya' freq=2422 MHz) Oct 1 08:55:58 ares kernel: [ 8791.070815] wlan0: authenticated Oct 1 08:55:58 ares NetworkManager[1830]: (wlan0): supplicant interface state: authenticating -> associating Oct 1 08:55:58 ares kernel: [ 8791.091384] wlan0: associate with ce:67:c3:86:34:80 (try 1) Oct 1 08:55:58 ares kernel: [ 8791.100579] wlan0: RX ReassocResp from ce:67:c3:86:34:80 (capab=0x411 status=0 aid=2) Oct 1 08:55:58 ares kernel: [ 8791.100583] wlan0: associated Oct 1 08:55:58 ares wpa_supplicant[1859]: Associated with ce:67:c3:86:34:80 Oct 1 08:55:58 ares NetworkManager[1830]: (wlan0): supplicant interface state: associating -> associated Oct 1 08:56:04 ares kernel: [ 8797.894857] wlan0: deauthenticated from ce:67:c3:86:34:80 (Reason: 15) Oct 1 08:56:05 ares wpa_supplicant[1859]: CTRL-EVENT-DISCONNECTED bssid=ce:67:c3:86:34:80 reason=15 Oct 1 08:56:05 ares kernel: [ 8797.933108] cfg80211: Calling CRDA to update world regulatory domain Oct 1 08:56:05 ares NetworkManager[1830]: (wlan0): supplicant interface state: associated -> disconnected Oct 1 08:56:05 ares NetworkManager[1830]: (wlan0): supplicant interface state: disconnected -> scanning Oct 1 08:56:06 ares NetworkManager[1830]: Activation (wlan0/wireless): association took too long.

I have already tested changing the security scheme from WPA (AES) to WPA (AES/TKIP), WPA (TKIP), WEP and even without security, but the problem is the same. I own other laptops using the brcmsmac and b43 modules which do not have any problem with this router. On the other hand, I have successfully tested the laptop chip with other routers with success. I normally use NetworkManager as a wireless client, but have also tested wicd and manual configuration (through Debian ifupdown and wpa_supplicant), but still encounter the same problem. I do not have much control on the router as it is the one supplied by my internet provider, hence I cannot access to the logs. I suspect it might be a problem of the ath9k module and/or in the router itself, but I do not know how to confirm any of these speculations. I have already noticed similar issues [0] in the archive of the list, which lets me think I am in the right direction, but what extra information would you need to help you understand the issue?
