DHCP is not working. -----Original Message----- From: psyche-list-admin@redhat.com [mailto:psyche-list-admin@redhat.com]On Behalf Of Levinshtein, Eyal Sent: Thursday, January 30, 2003 2:47 PM To: 'psyche-list@redhat.com' Subject: RE: Wireless Networking, no gateway, no DNS. Dave, First I would like to say thank you so much for your time and dedication, I truly appreciate it. Second, reply to your message: The diagram you drew is 100% accurate in Windows XP. In WINDOWS XP: When the Laptop was configured to obtain IP from the Lucent AP, It GETS 169.254.93.100 (but no GW or DNS) That is why I had to hard code it. (one test should be to find out what the internal IP of the WAP) On my Red Hat Linux 8.0 (Dual Boot) using the above config, it doesnt want to work. Let me know your thoughts, Eyal Let's draw this out in a diagram: Laptop---(wireless)--------Lucent WAP===(ethernet)==Linksys router 169.254.93.100/16 (right) 169.254.x.x/16 (left) 192.168.1.150/24 (right) 192.168.1.1/24 (left) 24.x.x.x (right) Does this make sense? I had to go back and look over your comments again to put this together. It sounds/looks like the Lucent gets its IP via DHCP from the Linksys, and your laptop gets its IP via DHCP from the Lucent WAP. Apparently, however, this is not happening. Instead, you have to hard-code your IP and DNS entries in your laptop to make it work. Is this correct? Do you know the inside ("left" in the diagram) IP address of your Lucent WAP? Given that your subnet is 255.255.0.0 (16 bits, thus my /16 notation), the IP should follow the pattern I show in the diagram, 169.254.x.x. It sounds like DHCP is not working in the Lucent. This would explain why you had to hard-code your IP address, subnet mask, and DNS entries in WinXP. If you can get it working, you should be ok. In truth, it doesn't make any sense to me that WinXP shows the 169.254.x.x address, because that address space is only supposed to be used for APIPA (a different kind of automatic IP addressing), not DHCP. If my diagram is incorrect, then please correct it (including IP addresses) so we have a better understanding of how things are laid out. -- Dave Sherman MCSE, MCSA, CCNA "If we wanted you to understand it, we wouldn't call it code." -----Original Message----- From: Dave Sherman [mailto:dsherman@real-time.com] Sent: Thursday, January 30, 2003 1:54 PM To: RedHat 8.0 Subject: RE: Wireless Networking, no gateway, no DNS.
