File shareing problem

i have 2 routers, a switch and a modem
the modem is connected to the internet
router 1 (dlink) is connected to the modem
switch is connected to router 1 and has a bunch of pc's running off it and the wifi of router 1

now i have a second wifi router (netgear) to add a few more ports, it is connected to router 1
my internet works fine and the wifi is good too

my problem is when i try to use file shareing or print something on a device running of router 1 or the switch


any suggestions would be appriciated

THe Dlink is natting to probably 192.168.0.x. Then your wireless router is taking that address and natting to probably 192.168.1.x or another natted subnet. You can't route traffic between two nonroutable subnets.

So you have a few options - run the cable modem straight to the wireless router, then run the switch after the wireless router. then everything is on the wireless routers subnet. Do you need the dlink router? I'm guessing no.

If you do for some reason need the dlink, you can see if your wireless router can have the firmware replaced by something like ddwrt. Then you can set the wireless up as a dumb repeater instead of a firewall/router.

Does that help?
