I have a very very strange DHCP problem I can't work out. The problem is that my Macbook Pro cannot receive an IP from the billion DHCP server on my router. I have a Billion 7800N and various devices on the wired and wireless network (5 laptops, 2 desktops, 2 airport express's, 3+ iphones etc etc). Every device receives an IP fine, no problem, except for my Macbook Pro laptop, 15in 2007 model. Now, on the wired network, the laptop receives an ip fine, but the airport card can't. If I set the tcp/ip info manually everything is fine and life is good. So, I figured well, my airport card / mac-os must be stuffed. So I tested my airport card on many other networks. Lo and behold, dhcp works fine on the airport card. What you say??? Yes, works fine, no problem. So strangely, only when using my laptop and this 7800n device together, dhcp fails. This has been going on for some time, I can't remember when exactly but I've been trudging along fine manually configuring my IP, but it's come to the point that every time I take my laptop to another wifi network I have to turn on DHCP and vice versa when I return to my home network. It's annoying to say the least. I've updated my firmware to the latest 1.04c only yesterday and the problem still occurs. I thought I'd do a bit of a a look into what osx is doing so I set 'ipconfig setverbose 1' to spew the dhcp sequence into the system log. And the full packet trace of the dhcp sequence to the file "com.apple.IPConfiguration.bootp" found in /var/logs/. I'm no network engineer so I'm not sure exactly what is happening. But for those that can: I've hosted the com.apple.IPConfiguration.bootp log at http://files.me.com/johnwiles/hr5rqp and an exerp from the sys log concerning any dhcp events here: http://files.me.com/johnwiles/b3n72q Please have a look. Any help is much appreciated!
