Problem setting up workgroup between laptop and main computer

Apolgies if I'm not so good with the terminology - I've had a look
around the web and suspect the problem may be a bit complicated.

I've got a Buffalo wireless router plugged into my phone line.

I have a Linksys Wireless Bridge ethernet into which I've plugged an
Xbox 360 and my main computer.

I'm trying to share files between my main computer and my laptop.
They're both apparently on the same workgroup MSHOME but cannot see
each other's shared files.

I've used run/cmd/ipconfig to trying pinging etc

My main computer's IP 192.168.1.170 and its default gateway
192.168.1.129. It can ping these both just fine.

My laptops IP is 192.168.1.2 and its default gateway 192.168.1.1

My main computer can ping all four of these addresses just fine. My
laptop can only successfully ping 192.168.1.1.

I'm at a loss - should the default gateways be different? Anything
else I can try? Thanks

In most cases, one way ping is firewall issue. Check the below troubleshooting page. By the way, why does each computer point to the different gateway?

Hi
Judging from the numbers and the way you describe your setting it seems that
your Network configuration is a little off.
Buffalo Wireless Router can not be plugged into a Tel. line, it need to be
plugged into modem that in turn should be plugged into the tel. line, if you
have DSL.
The Wireless Router has to be configured as the DHCP server, the IP and
default Gateway of the computers should be set to Auto. They can be changed
to manual (if necessary) after every thing works on auto and providing that
you have a real understanding how manual setting is done, and what IP
choices are valid.
The computers as to be configured to obtain Automatically their IP etc. from
the Router.
Log here there are few pages that describe basic configuration of Wired and
Wireless Network.
http://www.ezlan.net
As per Sharing per-se.
Successful Sharing involves some general consideration in Network settings,
http://www.ezlan.net/sharing.html
As well as specific adjustment of each computer according to what is allowed
to be shared.

Thanks for the replies.

The computers are both set to auto for IP addresses and gateways.

I've tried turning off all firewalls, and it doesn't seem to make a
difference.

A bit more info about my setup: My Buffalo is an ADSL modem/wireless
router, and the other Router is a Linksys WRT54g running DD-WRT setup
to work as a wireless access point for the main computer and consoles
(which are connected to the Linksys wired). Part of the setup of the
WRT54g involved setting the subnet mask on it as 255.255.255.128,
whereas this is set to 255.255.255.0 on the buffalo. The WRT54g is
also set up as a DHCP server (on a different range of IP addresses
than the Buffalo).

I've tried changing the subnet masks to be the same on both routers,
but this stops internet access on the Linksys.

Is there a way of keeping the WRT54g working as an access point, but
also get the main computer and laptop seeing each other on the
network?

It's sorted now - it was just an issue with the setup of DD WRT. It
was set up as a client with its own subnet and DHCP server, whereas is
needed to be setup as a client bridge on the same subnet as the main
router. Once I got the primary router to assign an IP address to the
machines using the secondary router, it was plain sailing.
