I finally figured it out. The cheap router I share with my neighbor does 
not handle IPv6. After disabling IPv6 all is good:


echo net.ipv6.conf.all.disable_ipv6=1 > /etc/sysctl.d/disableipv6.conf

edit /etc/modprobe.d/aliases.conf and
  * Comment out:
    alias net-pf-10 ipv6
  * Add:
    alias net-pf-10 off
    alias ipv6 off

and also setting network.dns.disableIPv6 to true for Iceweasel and 
Thunderbird
