Connecting to multiple networks

Hi everyone,

I wanted to know if i can have my computer connect 2 networks @ the same time

I have a Network card which connects to local area network and i added a wireless adapter to access the internet bcoz we can only have wireless access to internet.

When i connect my wireless adapter i am forced to disable the lan which is local area connection 2 so that i can browse internet and when i want to access the lan i have to disconnect the LAN$ which is the wireless adapter.

is there any workaround where i dont have to disable these and have access to the internet and lan @ same time

Ethernet adapter Local Area Connection 4: <<<<<<< Wireless Adapter ( Cable Modem >>> Wireless Router )

        Connection-specific DNS Suffix  . :
        IP Address. . . . . . . . . . . . : 192.168.1.126
        Subnet Mask . . . . . . . . . . . : 255.255.255.0
        Default Gateway . . . . . . . . . : 192.168.1.1

Ethernet adapter Local Area Connection 2: <<<<<< Lan ( Server >>> Switch >>> computer)

        Connection-specific DNS Suffix  . :
        IP Address. . . . . . . . . . . . : 192.168.1.61

In general You can do it what You suggested, but in this circumstances You have bad luck.
Both networks You are connecting are 192.168.1/24, so computer have same network on both cards (eth, wifi) (it would work, if your system was a eth bridge :).
And moreover, You can only have one default gateway, so If You tend to connect to two networks, You can have gateway set only on one of them.

  I know when you set up Windows Server versions to access two networks you set it as a router.
  Then (it has been a while) you set the NIC card leading out to the Internet up normally and the
  second NIC is set up with NO default gatway.  This also required DNS to resolve on the computer
  if you used computer names instead of IP addresses to connect to Internal computers.

  Internal NIC
  IP Address. . . . . . . . . . . . : 192.168.1.61
  Subnet Mask . . . . . . . . . . . : 255.255.255.0
  Default Gateway . . . . . . . . . :

  Since must people run Client (Windows 2000/XP) at home then I was thinking if setting up
  port forwarding for File and print sharing to the other computer on the network.  My theory
  is that since you Don't run DNS internally but the LAN is capable of forwarding services and
  ports that when you use the internal IP address to connect and share files the Router will forward the
  request directly to the other computer (like a switch.)

  I am planning on working on this over the next three days and will update you.

  Good Luck.

Hi Kris,
Thanks for posting the ipconfig printouts, that helps to understand the problem.

And the problem is... both interfaces have IP addresses that are too similar:
both your LAN and your wireless networks use the address range 192.168.1.1 through 192.168.1.254

There are two possible solutions:
1. talk to the administrators of the LAN and also of the wireless to see if you can get a different address range on either one
2. set up static routes to route all non-LAN traffic through 192.168.1.254, and all LAN traffic through 192.168.1.1.  Be careful to seperate out traffic for 192.168.1.254 so that it is NOT sent to the LAN!! (This could get tricky.)

The best solution is let the administrators of the LAN and the wireless work it out.

LOL - looks like three of us were typing answers at the same time!  Not bad for a question that is "only" worth 250 points.
It really attracts attention because the good ipconfig info is posted in the question!
