Two Routers?

There's an old, simple setup that I am redoing and expanding, but
here's a bit more detail on what I'm thinking...

The modem is an existing DSL modem which I will probably keep.

Router/Switch #1 will be new, probably Gigabit capable and won't need
integrated modem. I will probably have a separate 802.11b/g wireless
access point. May want to go with 802.11n in future. The need
for wireless is not too great right now.

Router/Switch #2 will be Gigabit capable since some of the systems
have Gigabit adapters

Most of the PC #1x are laptops and will have the option of
using wired or wireless. Most of PC #2x are desktops, but
some may want to connect their laptops on the #2 side
of the router/switch.

There are no restrictions (I assume you mean to the internet).

The system, in the near future have no server, but I want to have
the ability for the #2x PCs to share data.

I was just going to make Router/Switch #2 a Switch but I thought
one can restrict access into the #2 side by using a router. Is
this not correct? And if it is possible, can it be configured where
systems on #1 side can access specific #2 computers?

Currently there about 7 computers, but it may expand.

Thanks...

Ok, Sala, but WHERE is this modem connected too?
And how are the PC#1 connected to the PC#2?
What belongs to a LAN setup and what to a WLAN setup?

Ok, so this is a candidate for WLAN?

WHY do You think they might have virsuses?

Ok, but this does not identify the physical connection.

This has nothing to do with a server.

Not sure what You want. But access on LAN would need
specific LAN accesses: i.e. on PC#2 You will specify what other
users of PC#1 will have access via user/password.

> Currently there about 7 computers, but it may expand.
No problem - but only ONE may provide the I-Net connection!
Then You need to setup ICS (internet connecton share) and define
the other PCs that might use this interface.
But do not mix this up with LAN access to another PC.
This is a type of network setup (LAN) and access regulations.
If You don't want that any PC#1 can access any PC#2 data, then
don't allow such an access. And for specifics establish special logons.
This will need special users identified by password.

NO, this has nothing to do with router setup!
It only depends on network (LAN) setup.

But as I said before, without telling Your exact HW setup, there would
be only guessings.
