Thread: Cannot obtain DHCP lease

-

hi, i'm beginning learn linux networking, please bear me. have home wifi network has been working fine ages, supports 2 windows-based laptops , wm5 smartphone. connect wifi router (linksys wrt54g) in turn connects adsl modem (huawei mt882). router configured wep key, ssid not being broadcast, , mac addresses must whitelisted. try follow wireless network security practice. have nat running between router , modem.

working fine windows clients, , trying add linux box mix. setting older hp pavilion 510a desktop ubuntu v8.04lts, using realtek rtl8185 wlan card. machine has onboard rtl8139 lan adaptor also, works fine when plug in directly ethernet port on wireless router. wlan, however, not seem getting dhcp packet, , keeps on autoconfiguring 169.254.x.x address. when try giving static ip address doesn't connect either.

can see screenshots below, wlan working fine. have installed using ndiswrapper , windows drivers. i've been through comprehensive ndiswrapper troubleshooting guide did not resolve problem.




configured network myself, , works windows machines. lack of experience linux preventing me getting wireless work under linux. can hdcp packet in linux when connected lan using rtl8139 adaptor, not on wlan using rtl8185 adaptor. advice appreciated.

try
sudo dhclient wlan0
