I have 5 PC's and a printer connected to two ATT Plug&Share 6800G. I get internet through DSL modem. Router1 has 3 PC's connected and is connected to DSL modem through WAN port. Router2 has 2 PC's and a network printer connected to LAN ports and is connected to Router1 via WAN port. Modem has 192.168 address, Router1 is 172.16.0.1 , Router2 is 172.16.1.1 . All PC's are on the same Workgroup, 3 have WinXP pro, 1 is WinXP home and 1 pc is Win98 SE. All PC's can connect to the internet, 3 PC's on Router1 can see each other and share files, 2 PC's on Router2 can also see each other, share files, and print to the netvork printer connected to Router2. However, PC's connected to Router1 can't see PC's on Router2 (and vice versa), nor they can print to the printer connected to Router2.
Question:
What do I need to do to have all PC's share files and Router1 PC's print to the printer on Router2?
Any help would be greatly appreciated.

Router2 is able to access internet because router1 is just passing the connection through without considering the IPs.

Here's what I feel that you should do..
Try to ping your router 2 PCs.
check your router2's gateway address? It should be router1's Ip address.
Make sure that your submask is different for both routers. ex. router1 255.255.0.0, router2 255.255.0.1

Still no luck:
I mada changes per your suggestions and still the same. From PC on Router1 I can ping all 5 PC's, but from PC on Router1 I can only ping PC's connected to Router1. Here are the settings:

LAN
IP Address: 172.16.0.1
Subnet Mask: 255.255.255.0
DHCP Server: Enabled
WAN
IP Address: 192.168.0.102
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.0.1
DNS: 192.168.0.1 xxx.xxx.x.xx

ROUTER 2:
LAN
IP Address: 172.16.1.1
Subnet Mask: 255.255.255.128
DHCP Server: Enabled
WAN
IP Address: 172.16.0.102
Subnet Mask: 255.255.255.0
Default Gateway: 172.16.0.1
DNS: 172.16.0.102

Thanks in advance
