A Wireless Network within a Wireless Network

I have a customer whose network is both wired and wireless.
The wireless portion of the network and wired are both isolated.

Point A = Wired, Point B = Wireless

Point B is being design and acomplished by assigning a single computer with a wireless device to connect to the new SSD network.

In addition Point B will have 7 workstations that are not wireless capable. This mini network will be a total of 8 computers. I have only a single computer that is able to get wireless. In order for the other computers to be on a network, I have added a router and a switch.

How do I go about configuring such an animal because the moment I add the router, the wireless computer looses its configuration due to the new router that is attached to. Other than that in this mini network, (Point B), all computers can now see each other

Not 100% sure what your aim is here, but from what i understand you are asking how to connect a single machine to 2 different networks? I.e. its already connected to wireless, so how do you connect it to the new router as well?

Can you explain this a bit more clearer so we can help?
As for it connecting to the new router - are you connecting by LAN cable?

Yes I know this sounds kind of confusing.
The customer has a wireless computer which has Internet.
He wants 7 more computers to connect to this wireless computer to get the interent from it.

I believe this could be done.
Thing is for the other 7 computers to see this wireless desktop, I have added a router and a switch. The router is wireless but I have disable the wireless capability.

In order for the 7 workstations to see the wireless computer, I have attached it to the router. When I do this, the wireless PC loosing its connection.

Once I have setup the wireless computer to use the router correctly possibly the wireless would work. I have never done something like this before in my life.

The quick fix is running a Cat6 cable from router PointA to PointB but customer does not want this.

The wireless pc loses its connection cause it can't connect to 2 different routers at the same time...unless it itself is a router

Just so I am clear(cause I'm still struggling with the config/layout of your network)

PC is connected to an existing network
You've added 7 workstations to the same room this first pc is in
You want those machines to connect to the pc to obtain internet? Can I be stupid here and ask why?

If this were me the proper way to do this is with an access point, not a router

Get a wireless access point, connect it back to the same line as the existing pc is connected to - then config that access point with wireless network name/security etc...

Then the other 7 machines will have access to internet through that access point...

To do it your way you'd need to enable routing on the existing pc(assume its Windows 7 yes?) which doesn't offer any advantage that I can see(plus its not easy)

Not at all....the owners dont want any wires to be run to this location.
The other 7 computer can not be wireless they dont have the hardware capability else I would do them wireless.

An Access Point?
Doesnt the access point need to be wired attached to it to magnify the signal?
Please let me know.
Yes...but again I'm obviously missing something...

The pc with internet currently - how does it obtain internet?
Your original title of the question was 'a wireless network within a wireless network'

So the first pc already receives wireless from somewhere I assume? And you want to somehow boost this signal in the new location?

If this first pc receives internet can you explain how it does and maybe I can point you in the right direction...sorry if this is dragging out a bit but not 100% clear on all the details
If the pc is currently receiving internet wirelessly what you really need is an access point that supports wireless bridging...

Eg...in the main location you have a router and the pc in question is receiving wireless from there, what you need is to get a wireless AP that will 'bridge' the signal from location A to location B

Now to make this work you need to get compatible ap's/routers
What make router(or AP) is in location A?

As an example Netgear AP's will talk to Netgear AP's/routers and allow these wireless bridges to form, not saying different makes/models won't talk - but sometimes it all depends on the settings in the AP/router

Anyways, once you setup the bridge, the clients in location B can then connect to the new AP and all is good...

** The PC with Internet currently is obtaining the internet via a wireless PCI expansion card.
** So yes the title was to build a wired network of a wireless pc.

So the first pc already receives wireless from somewhere I assume?
Yes of a wireless router.

If this first pc receives internet can you explain how.
Yes of a wireless router.

I know even for me creating this network is difficult.
Yes...so instead of the pc getting wireless, get an AP that will connect to the existing wireless in bridge mode, plus since the other workstations in location B don't have wireless(just seeing that now) I'd then use the switch in location B - plug in the AP into the switch and it will distribute internet to the internal machines

What you are trying to do with another router isn't going to help, since the router itself isn't connected to the original wireless therefore can't get to internet...

I will also assume since PC-A(the working one) can receive wireless - this means there is a decent wireless signal in the building, so another AP bridging from that existing wireless signal should work

I understand the AP now.

How would DHCP work here then if not routing?

That is why at the begingnning I started using a router to DHCP.
The wireless bridge takes care of routing/DHCP...

Basically a wireless bridge is same as connecting 2 switches back to back
For example connecting from one building to another switch in 2nd building - since its still on the same physical network the 2nd building switch will pass traffic to the clients just like you were using 2 switches in the same building

Wireless bridge is exactly the same - 2 AP's(which at the end of the day are just switches with aerials) are connecting to each other and passing traffic from side to side...but again you need to get similar makes/models to be 100% sure of compatibility(which is why I mentioned Netgear models, since they have a setting called 'Wireless bridge' that allows you to connect to another netgear ap/router on the other side to distribute the wireless signal)

So again...what model router is on the working side of the network? Or is it another AP providing the wireless to PC-A?
If its an AP then check the settings for 'wireless bridge' and you should be ok - then just get same AP for the 2nd location and setup as per instructions...

One last thing - when an AP is in 'bridge mode' it doesn't always service client connections - Netgear models do allow both bridge and client access at same time - in their settings its called 'Wireless bridge with client access'

That's why its important to get 2 models the same, less to worry about with compatibility going forward...

I just thought of something....

Can I make the Windows 7 Ultimate PC a DHCP server?
Have a switch attach to the wireless PC and make this work without the AP?
Em...possibly, never actually tried that before but yes might work

You'd need 3rd party DHCP server though...so not sure how that would work
Or you could setup ICS(Internet Connection Sharing) within Windows itself
Into Network and Sharing center
Click Change Adapter settings on left
Right click wireless adapter, properties and select Sharing tab

Note when you do this it sets the machine up basically as a router, and DHCP...so might get you out of jail
use Internet Connection Sharing (ICS) on the host machine.  install a 2nd wireless card and connect it to that 2nd wireless ssid.  then go to the properties of the internet link on the host computer and enable ICS and bridge it to the 2nd wireless card.

personally I still agree with previous comments that you should just go the AP route, but this is a second option.  ICS takes care of DHCP for you.

Ok I was able to do it the following way:

I enable Windows 7 Ultimate Internet Wireless sharing.
I disable the router and only left the switch.
I hooked up the Wireless PC Ethernet connection to the switch.
Then I bonded or bridged the wireless connection to the wired ethernet connection a WOALA!!!

Internet for ALL PCS thru a single Wireless computer serving as a DHCP server.

AP was not the solution, too much work.
Installing another wireless card did not make sence to me.

I have never done this type of connection but last night I was amazed to see how it worked.
Its like allowing your computers accessibility thru your cell phone service.

Thank You guys but I was looking for a more robust, easy to install and configuration.
This by far was the best.
Ok, I guess I misunderstood what was written.  I thought you needed to connect the computer to two SSIDs, not just perform a bridge from the wired to the wireless network

I was able to bridge both wireless and wired connection thru the wireless pc and WHAM!
Internet for all wired PC's.
