You are off to a good start. I'm not theoretically advanced enough to offer any more than some practical knowledge derived from my own fiddling. Between Google and help forums you can do anything imaginable.

If you use static IP assignment, and you should whenever possible, you can assign multiple subnets to a single network card. This allows you to network with devices on different subnets with a single NIC. I use this feature a lot, and find it very handy. It would allow your laptop to work in the 192.168.0.xxx subnet and still allow it to access the router on the 192.168.2.xxx subnet. It does not work with a DHCP configured NIC, so it will not be very good to do to your laptop. Click the picture for full size.

Make it 192.168.0.2 and you will be able to access it anytime you like. The reason 192.168.2.1 is invisible is because it is a different subnet. The subnet mask of 255.255.255.0 means that only the last octet is available and the first 3 octets need to be the same for the devices to communicate. The answer can get a lot more complicated real fast, but for what you are doing, that should suffice.

When you need to change the programming of AP2 you will need to manually program the laptop with an address in the 192.168.2.xxx range. It should not be much of an inconvenience since you only need to program the router about once every 7 years.

Needing to access the router's console once every 7 years? Where are you getting that number from?

And even assuming it's true, it's not answering the question; that being, why can't I access the router as is? Maybe you answered it and I just didn't realize, but please clarify. It's disconcerting to say the least that I don't have access to my own router due to some technical reason I don't understand.

If you need any specific info on my setup, let me know and I'll post it.

This is going to be a problem. What is the make and model of AP2 ?

Edit - Looks like you are messing with the DHCP of the WAN. That is not the DHCP I was referring to. It is the DHCP SERVER in AP2 that needs to be disabled. Also, the connection from PC NIC2 and AP2 should be to a LAN port of AP2, not it's WAN port.

Yes ! The computer portion of the access point has nothing to do with network connectivity. You can make it 10.10.10.10 if you wanted to and it would work fine. I always put my access points in their own subnet just for neatness.

Edit - If AP2 has a DHCP server be sure to turn it off.

:

Can you explain the conflicts?

Ok, I thought the LAN NIC IP is referring to what it is connecting to (i.e. AP2). I had no idea NICs actually have their own IP.

After I ran the Network Setup Wizard on the desktop, it defaulted the LAN NIC to 192.168.0.1 and no gateway, so I figured it was point to a device that should have that address, so I went ahead and manually changed AP2's IP to that as well.

So to fix this, does it matter what I change AP2's IP to? I will change it to 192.168.2.1 for logic's sake, but could I technically do 192.168.9.1, or 192.168.200.1 even?]]> http://www.dslreports.com/forum/remark,21204042 Thu, 02 Oct 2008 12:56:14 EDT Re: Is it possible to do this? http://www.dslreports.com/forum/remark,21204015 SipSizzurp :

:

Certainly. It's right in yer own post. The LAN NIC of the desktop is 192.168.0.1 and so is AP2. Change either device to a new address and the conflict will go away. Under the circumstances your general configuration is good and should do what you need.

Do you realize that if a laptop connects to AP1 it will have access to the Internet and will also be able to share files with the desktop right through that same connection ? You do not need AP2 to accomplish your stated goal. I see the conflicts with the current setup...

Second, this seems way more complicated then necessary...

As others suggest, having just 1 AP/network would surely work. If you want to limit OUTBOUND access to just one machine, you can likely do that in the first AP itself.

As drawn, you have "Desktop" as a multi-homed device. Depending on the OS, you need to configure it as such.

I'd ditch the second AP and go with the simpler setup...

It's not working.

---------

ipconfig (desktop):

LAN
DNS Suffix:
IP Address: 192.168.0.1
Subnet Mask: 255.255.255.0
Default Gateway:

Wireless
DNS Suffix: phub.net.cable.rogers.com
IP Address: 192.168.1.101
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.1.1

---------

Points of note:

• I manually set the LAN IP (AP2) to 192.168.0.1

• ICS seems to work for a moment, until the desktop complains about an IP address conflict, at which point ICS stops working.

• I can access the AP1 console (192.168.1.1) from the desktop, but I cannot access the AP2 console (192.168.0.1).
• I can access the AP2 console (192.168.0.1) from the notebook, but I cannot access the AP1 console (192.168.1.1).

• I tried changing the subnet of AP2 to 255.255.255.128 but it didn't do anything.

In short: I don't know what the heck is going on.

For example, whenever I'm using wireless on my laptop, and plug in an ethernet cable to share files with another computer through ethernet, my wireless stops working.

Does that have something to do with the "default gateway"?

I believe AP1 is a wireless router, how about AP2, if it is also a router, you have to disable DHCP in AP2. If AP1 and AP2 are from same manufacturer, you will have a crash in their gateway IP. That is why "make sure they are in different subnet".

anyway, have everything hook up (the way you have problem), in the desktop, post the result of IPCONFIG/ALL and we will have a better mental picture.

I have a desktop that has a wireless PCI card, using it to access the Net from an AP.

I want to have it also connected to another AP to use as a local network (intranet?), for sharing of files between other computers and the desktop.

Note that the two APs are separate (AP1 has access to the Net and is used by the desktop wirelessly to access the Net, and AP2 has no access to the Net but is used to share files on the desktop with other computers).

In other words, can my desktop access the Internet using a wireless card through AP1, while sharing its files with computers on the local intranet using AP2?

Here is a diagram (with color-coding!) to explain what I mean:
