wifi network connection

[hce <webmail.hce@gmail.com>]

Hi,

I am doing an experiment to set up a home wifi network. The setup is
descripbed as follows:

I have a laptop running Debian connected to the ISP via phone line
(ppp), the laptop has also an ethernet port, I set it to 192.168.5.1
which connectes to a wifi router at Internet port. The wifi local LAN
IP address  to 192.168.2.1. The nameserver in laptop is assigned by
ISP 139.134.2.190 and the default gw in laptop does not have an IP
address, but the iface = ppp0.

I have another desktop connect tot he wifi LAN via udhcpc, it gets the
ip address 192.168.0.252 from DHCP server of wifi route. On the
desktop, the nameserver in resolv.conf sets to 192.168.0.1 and default
gw sets to 192.168.0.1. But, the desktop could not connect to the
internet. Any help what I was missing?

Thank you.

Jim
