hi, I disabled ufw entirely and rebooted for effect: no change.
I prevented avahi-daemon from using ipv6: no effect My AP is a WR702N, with a new firmware from 2016, I converted it to a router, no effect whatsoever (symptoms are the same: cannot event ping the device even in static ip) dhclient throws a loop of those lines before timing out: dhclient[2845]: DHCPDISCOVER on wlp3s0 to 255.255.255.255 port 67 interval 3 (xid=0x6c648c32) when connecting directly to the router dhclient sends a dhclient[2866]: DHCPREQUEST of 192.168.0.163 on wlp3s0 to 255.255.255.255 port 67 without the DHCPDISCOVER part I tried disabling rp filters in sysctl, no effect I tried using igmpv2, no effect. thanks -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to ufw in Ubuntu. https://bugs.launchpad.net/bugs/1574474 Title: Xenial fails to connect my intermediate AP (dhcp multicast) Status in ufw package in Ubuntu: Incomplete Bug description: Hi, On Xenial, neither manual nor automatic tools can connect to an intermediary AP (TPLINK TL-WR702N).
