My dhclient or dhcpcd can't receive an IP. > When I set a static IP, I can't ping the gateway. dhclient is not suitable for wireless networking because it brings the interface down briefly and breaks the connection. So I suggest that you use static addresses or a DHCP client that doesn't bring the interface down. Please check iwconfig output. In particular, please see "access point" and "link quality". If the later is 0, there is no association. If there is no association, no IP packets can go through. Try reestablishing the association by setting ESSID with iwconfig while the interface is up. Also please see the kernel log for possible signs of trouble. It's shown by the "dmesg" command. -- Regards, Pavel Roskin
