Hi!

The frustration reached unimaginable levels... as I do not know where to look anymore...

I have the following setup:
- internet into a modem / 4x router
- from router to one desktop (wired) and router / AP (wired)
- the AP enables a wireless network for one laptop.

Modem = 192.168.1.1 (default gateway as well, DNS servers correctly declared)
AP = 192.168.1.254
desktop = 192.168.1.2
laptop = 192.168.1.3

The IPs are set based on the MAC addresses (I need to do this to forward ports, I cannot leave them to get any IP).

From Laptop I can ping all the other three.
From desktop I can ping the modem / router and the AP, but NOT the laptop!!
I can access Internet OK from any of the computers.
I want to be able to transfer files from one to the other. I got it working at a point but I moved house after that and when I re-installed all the components, it does not work properly anymore...

DHCP server enabled on the modem / router and turned off on the wireless AP.

Any ideas wher should I be looking to?
Thank you.

It sounds like you have a firewall enabled on the laptop.
What O/S are you running on each?

Opinions are my own and not the views of my employer.

Do you have the AP in bridge mode? Sounds like you've potentially got some NAT issues.

Thak you for the quick replies!

Both computers run XP Pro.
Both have Firewall enabled but it made no difference when I disable it.
I tried with the AP in Bridge mode and without it, no change in behaviour.

I created a home network on both, same workgroup, but when I want to add new places, I cannot see the other computer (I believe it will not work until the ping issue is resolved)

NAT is set on "SUA only", it was always on this setting, I really do not know what the others do. Then click on "edit details" and is the screen where I forward ports. I selected "None" on the NAT page, still no improvement. I also deleted all the entries in the SUA page and re-enabled it, and is still the same, can ping from laptop but not from desktop.

It looks like I am back to transferring 1.5Gb files with the USB stick...

The other thing that could be going on is that the wired network is setup as a "DMZ", that would prevent it from gaining access to the wireless, "internal" network.
