this sounds like a problem setting up dns and routes from a dhcp serving access point you should be getting something like route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.0.0 0.0.0.0 255.255.255.0 U 0 0 0 wlan0 0.0.0.0 192.168.0.1 0.0.0.0 UG 0 0 0 wlan0 and cat /etc/resolv.conf nameserver 192.168.0.1 .. if the update broke dhcp for *your* router, you can configure dns and route manually for e.g. set a dns server echo 4.2.2.1 > /etc/resolv.conf add a route route add default gw 192.168.0.1
