Could it be that IPv6 responses are being remembered when talking to a non-AP0 but then can't be used with AP0? If the laptop temporarily disabled IPv6 on the Wi-Fi interface then it would be using IPv4 to all APs? Something like this should do. It's temporary, resetting to default on reboot. i=wls34 # Change to suit. ip a s dev $i # Show the ‘before’. sysctl net.ipv6.conf.$i.disable_ipv6 sudo -i sysctl net.ipv6.conf.$i.disable_ipv6=1 ip a s dev $i -- Cheers, Ralph. -- Next meeting: BEC, Bournemouth, Tuesday, 2019-08-06 20:00 Check to whom you are replying Meetings, mailing list, IRC, ... http://dorset.lug.org.uk/ New thread, don't hijack: mailto:dorset@mailman.lug.org.uk
