Jaunty network problem

[Huisi Wang]

Hi there,

I installed jaunty on my laptop, Dell 640m. I find a network problem.
When I use wired network interface, my ip address is 192.168.86.41, I
can only access the hosts in 192.168.86.x. When I use wireless network
interface, everything works fine.

I'm wondering how to solve this problem. Any ideas?

Thanks,
Huisi
