Thanks for the instructions. I hope I can try tomorrow (I need to bring my laptop there). In the mean time, I could try another open wifi hotspot that was reachable, and the connection was successful. I could see a difference in the kernel logs. This time, I had the following additional lines: Dec 12 10:36:50 zira kernel: wlp61s0: authenticate with 14:0c:76:9f:e9:d9 Dec 12 10:36:50 zira kernel: wlp61s0: send auth to 14:0c:76:9f:e9:d9 (try 1/3) Dec 12 10:36:50 zira kernel: wlp61s0: aborting authentication with 14:0c:76:9f:e9:d9 by local choice (Reason: 3=DEAUTH_LEAVING) Dec 12 10:36:50 zira kernel: wlp61s0: authenticate with 14:0c:76:9f:e9:d9 Dec 12 10:36:50 zira kernel: wlp61s0: send auth to 14:0c:76:9f:e9:d9 (try 1/3) Dec 12 10:36:50 zira kernel: wlp61s0: authenticated Dec 12 10:36:50 zira kernel: wlp61s0: associate with 14:0c:76:9f:e9:d9 (try 1/3) Dec 12 10:36:50 zira kernel: wlp61s0: RX AssocResp from 14:0c:76:9f:e9:d9 (capab=0x401 status=0 aid=1) Dec 12 10:36:50 zira kernel: wlp61s0: associated Dec 12 10:36:50 zira kernel: IPv6: ADDRCONF(NETDEV_CHANGE): wlp61s0: link becomes ready So, the issue was not due to DHCP. BTW, I don't know whether this is related, but I sometimes see a kernel warning with a trace, e.g. Dec 11 11:01:43 zira kernel: ------------[ cut here ]------------ Dec 11 11:01:43 zira kernel: TX on unused queue 2 Dec 11 11:01:43 zira kernel: WARNING: CPU: 0 PID: 2545 at /build/linux-F3l5KA/linux-4.18.20/drivers/net/wireless/intel/iwlwifi/pcie/tx.c:2287 iwl_trans_pcie_tx+0xdab/0x1180 [iwlwifi] [...] -- Vincent Lefèvre <vinc...@vinc17.net> - Web: <https://www.vinc17.net/> 100% accessible validated (X)HTML - Blog: <https://www.vinc17.net/blog/> Work: CR INRIA - computer arithmetic / AriC project (LIP, ENS-Lyon)
