I have the following configuration

<switch>---<modem>----Internet
| rrrrr|
| rr <PC-1>
| rrrrrrrrrrrrrrrrrrrrrrrusb
<DIR-825 router>--------<printer>
| rrrrrrr|
| rrrr <other PC's>
|
<MyBook HDisk>

How do I make PC-1 to see <printer> and <MyBook> so it can use them?

You can replace the switch with another router, but that alone will do nothing to fix your problem as the original router is still blocking PC-1 from accessing the network drive and printer.

You will need to configure the original router to be a wireless access point, this strips away the traffic routing functions and makes it just a wifi extension of your network. If you search "congiure <router manufacturer> as an access point" you should find more detailed informaiton on the process. The main things you need to do is dissable NAT and SPI firewalls, dissable dhcp, set the access points IP address to be in the subnet of the new router (but outside of the dhcp range), and plug the ethernet cable into a LAN port instead of the WAN...

Sorry, I forgot to tell that the switch and the router are in two separate and somewhat far rooms and the printer (which is connected to the usb port of the router) needs to be in the room where the other pcs are.
Tks anyway.

The reason that PC1 can not connect to your network drive/printer is becasue PC-1 is before the router.

Your router is seeing PC-1 as an outside connection (as if it is a remote computer someehre over the internet). If PC-1 is a webserver or something that requires customrs to access it then it needs to be in its current configuration, otherwise having PC-1 in front of the router is a big security issue as it is not being protected by the nat firewall in the router.

You have one of 4 options.
1) relocate modem to be near router
2) relocate pc-1 somewhere else
3) Install 2nd ethernet cable from router to switch location.
4) buy network print server device so you can switch the locaiton of your router and switch.

Tks alot but 1, 2 & 3 can't do. 4, maybe. What if I replace the switch with another router, would it be possible to accomplish what I need?

The only mild concern is if it would break your USB print server function. There is no reason for it to, but I have seen weirder/stupider things before.

If you utilize wireless and the wifi being in its current locaiton is ideal, then the router/access point option is the best one. If you dont need wireless or you need it more in the switch/pc-1 location then the usb-network print server is the simplier option.
