I have a fresh install of Linux Mint Mate 64 on an old iMac (late 2008). I can not connect using a network cable so I need to use wlan. I've installed broadcom drivers, the network managers shows the wi-fi connection and everything seems fine... but I cannot connect to anything except localhost.
I've tried to reduce the problem and I believe I've a problem connecting to the router. If I ping it, I get 100% packet lost. If I ping broadcast I receive replies from the router!
$ ping 192.168.10.1 PING 192.168.10.1 (192.168.10.1) 56(84) bytes of data. From 192.168.10.111 icmp_seq=1 Destination Host Unreachable $ ping -b 192.1168.10.255 WARNING: pinging broadcast address PING 192.168.10.255 (192.168.10.255) 56(84) bytes of data. 64 bytes from 192.168.10.1: icmp_seq=3 ttl=255 time=299ms ...
Please note that DHCP works, since the machine is correctly identified as 192.168.10.111 in the first
EDIT 1: more info
$ arp -a Address HWtype HWaddress Flags Mask Iface 192.168.10.104 (incomplete) wlan0 192.168.10.112 ether 38:c9:86:24:d6:88 C wlan0 192.168.10.1 (incomplete) wlan0 # arp -d 192.168.10.1
no reply, the command returns without any output.
$ route -an
the "a" flag was not recognized.

please note that I've successfully removed 169.254.0.0 route previously, but it re-appeared after re-starting network manager.

EDIT 2 on a different machine, in the same network (using wi-fi connection as well)
arp -areturns the following:
$ arp -a ? (169.254.221.46) at c8:ff:28:46:52:c5 on en1 [ethernet] router.local (192.168.10.1) at 0:a0:a2:62:c1:dc on en1 ifscope [ethernet] nas.local (192.168.10.104) at 0:11:32:38:e:1 on en1 ifscope [ethernet] ?

The machine is a mac, so the
route command does not provide a list of routes but I've tried a different command

I'm still investigating on the origin of 169.254.x.x routes, but they does not seems to cause any issues on other machines.
END EDIT 2
$ arping -I wlan 0:a0:a2:62:c1:dc arping: unknown host 0:a0:a2:62:c1:dc
Trying to ping/arping other machines returns "Destination Host Unreachable" for every machine in the arp list, using both IPv6 and IPv4 addresses
END EDIT 3
I have no idea how to "debug" this connection issue. I've searched forums, I've tried to set BSSID manually (it was empty), I've set DNS to 192.168.10.1,18.104.22.168 (and restarting everything so many times) but with no luck. What should I try?
